Detailed Description

The Qt namespace contains miscellaneous identifiers used throughout the Qt library.
PySide.QtCore.Qt.ShortcutContext

For a QEvent.Shortcut event to occur, the shortcut’s key sequence must be entered by the user in a context where the shortcut is active. The possible contexts are these:

Constant Description
Qt.WidgetShortcut The shortcut is active when its parent widget has focus.
Qt.WidgetWithChildrenShortcut The shortcut is active when its parent widget, or any of its children has focus. Children which are top-level widgets, except pop-ups, are not affected by this shortcut context.
Qt.WindowShortcut The shortcut is active when its parent widget is a logical subwidget of the active top-level window.
Qt.ApplicationShortcut The shortcut is active when one of the applications windows are active.
PySide.QtCore.Qt.CheckState

This enum describes the state of checkable items, controls, and widgets.

Constant Description
Qt.Unchecked The item is unchecked.
Qt.PartiallyChecked The item is partially checked. Items in hierarchical models may be partially checked if some, but not all, of their children are checked.
Qt.Checked The item is checked.

PySide.QtCore.Qt.FocusPolicy

This enum type defines the various policies a widget can have with respect to acquiring keyboard focus.

Constant Description
Qt.TabFocus the widget accepts focus by tabbing.
Qt.ClickFocus the widget accepts focus by clicking.
Qt.StrongFocus the widget accepts focus by both tabbing and clicking. On Mac OS X this will also be indicate that the widget accepts tab focus when in ‘Text/List focus mode’.
Qt.WheelFocus like Qt.StrongFocus plus the widget accepts focus by using the mouse wheel.
Qt.NoFocus the widget does not accept focus.
PySide.QtCore.Qt.GestureType

This enum type describes the standard gestures.

Constant Description
Qt.TapGesture A Tap gesture.
Qt.TapAndHoldGesture A Tap-And-Hold (Long-Tap) gesture.
Qt.PanGesture A Pan gesture.
Qt.PinchGesture A Pinch gesture.
Qt.SwipeGesture A Swipe gesture.
Qt.CustomGesture A flag that can be used to test if the gesture is a user-defined gesture ID.

User-defined gestures are registered with the QGestureRecognizer.registerRecognizer() function which generates a custom gesture ID with the Qt.CustomGesture flag set.

PySide.QtGui.QGesture QWidget.grabGesture() QGraphicsObject.grabGesture()

Note

This enum was introduced or modified in Qt 4.6

PySide.QtCore.Qt.DropAction
Constant Description
Qt.CopyAction Copy the data to the target.
Qt.MoveAction Move the data from the source to the target.
Qt.LinkAction Create a link from the source to the target.
Qt.ActionMask  
Qt.IgnoreAction Ignore the action (do nothing with the data).
Qt.TargetMoveAction On Windows, this value is used when the ownership of the D&D data should be taken over by the target application, i.e., the source application should not delete the data. .. raw:: html <br /> On X11 this value is used to do a move. .. raw:: html <br /> TargetMoveAction is not used on the Mac.
PySide.QtCore.Qt.WindowType

This enum type is used to specify various window-system properties for the widget. They are fairly unusual but necessary in a few cases. Some of these flags depend on whether the underlying window manager supports them.

The main types are

Constant Description
Qt.Widget This is the default type for PySide.QtGui.QWidget . Widgets of this type are child widgets if they have a parent, and independent windows if they have no parent. See also Qt.Window and Qt.SubWindow .
Qt.Window Indicates that the widget is a window, usually with a window system frame and a title bar, irrespective of whether the widget has a parent or not. Note that it is not possible to unset this flag if the widget does not have a parent.
Qt.Dialog Indicates that the widget is a window that should be decorated as a dialog (i.e., typically no maximize or minimize buttons in the title bar). This is the default type for PySide.QtGui.QDialog . If you want to use it as a modal dialog, it should be launched from another window, or have a parent and used with the QWidget.windowModality property. If you make it modal, the dialog will prevent other top-level windows in the application from getting any input. We refer to a top-level window that has a parent as a secondary window.
Qt.Sheet Indicates that the window is a Macintosh sheet. Since using a sheet implies window modality, the recommended way is to use QWidget.setWindowModality() , or QDialog.open() , instead.
Qt.Drawer Indicates that the widget is a Macintosh drawer.
Qt.Popup Indicates that the widget is a pop-up top-level window, i.e. that it is modal, but has a window system frame appropriate for pop-up menus.
Qt.Tool Indicates that the widget is a tool window. A tool window is often a small window with a smaller than usual title bar and decoration, typically used for collections of tool buttons. If there is a parent, the tool window will always be kept on top of it. If there isn’t a parent, you may consider using Qt.WindowStaysOnTopHint as well. If the window system supports it, a tool window can be decorated with a somewhat lighter frame. It can also be combined with Qt.FramelessWindowHint . .. raw:: html <br /> .. raw:: html <br /> On Mac OS X, tool windows correspond to the Floating class of windows. This means that the window lives on a level above normal windows; it impossible to put a normal window on top of it. By default, tool windows will disappear when the application is inactive. This can be controlled by the Qt.WA_MacAlwaysShowToolWindow attribute.
Qt.ToolTip Indicates that the widget is a tooltip. This is used internally to implement tooltips .
Qt.SplashScreen Indicates that the window is a splash screen. This is the default type for PySide.QtGui.QSplashScreen .
Qt.Desktop Indicates that this widget is the desktop. This is the type for PySide.QtGui.QDesktopWidget .
Qt.SubWindow Indicates that this widget is a sub-window, such as a PySide.QtGui.QMdiSubWindow widget.

There are also a number of flags which you can use to customize the appearance of top-level windows. These have no effect on other windows:

Constant Description
Qt.MSWindowsFixedSizeDialogHint Gives the window a thin dialog border on Windows. This style is traditionally used for fixed-size dialogs.
Qt.MSWindowsOwnDC Gives the window its own display context on Windows.
Qt.X11BypassWindowManagerHint Bypass the window manager completely. This results in a borderless window that is not managed at all (i.e., no keyboard input unless you call QWidget.activateWindow() manually).
Qt.FramelessWindowHint Produces a borderless window. The user cannot move or resize a borderless window via the window system. On X11, the result of the flag is dependent on the window manager and its ability to understand Motif and/or NETWM hints. Most existing modern window managers can handle this.

The CustomizeWindowHint flag is used to enable customization of the window controls. This flag must be set to allow the WindowTitleHint , WindowSystemMenuHint , WindowMinimizeButtonHint , WindowMaximizeButtonHint and WindowCloseButtonHint flags to be changed.

Constant Description
Qt.CustomizeWindowHint Turns off the default window title hints.
Qt.WindowTitleHint Gives the window a title bar.
Qt.WindowSystemMenuHint Adds a window system menu, and possibly a close button (for example on Mac). If you need to hide or show a close button, it is more portable to use WindowCloseButtonHint.
Qt.WindowMinimizeButtonHint Adds a minimize button. On some platforms this implies Qt.WindowSystemMenuHint for it to work.
Qt.WindowMaximizeButtonHint Adds a maximize button. On some platforms this implies Qt.WindowSystemMenuHint for it to work.
Qt.WindowMinMaxButtonsHint Adds a minimize and a maximize button. On some platforms this implies Qt.WindowSystemMenuHint for it to work.
Qt.WindowCloseButtonHint Adds a close button. On some platforms this implies Qt.WindowSystemMenuHint for it to work.
Qt.WindowContextHelpButtonHint Adds a context help button to dialogs. On some platforms this implies Qt.WindowSystemMenuHint for it to work.
Qt.MacWindowToolBarButtonHint On Mac OS X adds a tool bar button (i.e., the oblong button that is on the top right of windows that have toolbars).
Qt.BypassGraphicsProxyWidget Prevents the window and its children from automatically embedding themselves into a PySide.QtGui.QGraphicsProxyWidget if the parent widget is already embedded. You can set this flag if you want your widget to always be a toplevel widget on the desktop, regardless of whether the parent widget is embedded in a scene or not.
Qt.WindowShadeButtonHint  
Qt.WindowStaysOnTopHint Informs the window system that the window should stay on top of all other windows. Note that on some window managers on X11 you also have to pass Qt.X11BypassWindowManagerHint for this flag to work correctly.
Qt.WindowStaysOnBottomHint Informs the window system that the window should stay on bottom of all other windows. Note that on X11 this hint will work only in window managers that support _NET_WM_STATE_BELOW atom. If a window always on the bottom has a parent, the parent will also be left on the bottom. This window hint is currently not implemented for Mac OS X.
Qt.WindowOkButtonHint Adds an OK button to the window decoration of a dialog. Only supported for Windows CE.
Qt.WindowCancelButtonHint Adds a Cancel button to the window decoration of a dialog. Only supported for Windows CE.
Qt.WindowSoftkeysVisibleHint Makes softkeys visible when widget is fullscreen. Only supported for Symbian.
Qt.WindowSoftkeysRespondHint Makes softkeys to receive key events even when invisible. With this hint the softkey actions are triggered even the softkeys are invisible i.e. the window is displayed with showFullscreen(). Only supported for Symbian.
Qt.WindowType_Mask A mask for extracting the window type part of the window flags.

QWidget.windowFlags Window Flags Example

PySide.QtCore.Qt.DateFormat
Constant Description
Qt.TextDate The default Qt format, which includes the day and month name, the day number in the month, and the year in full. The day and month names will be short, localized names. This is basically equivalent to using the date format string, “ddd MMM d yyyy”. See QDate.toString() for more information.
Qt.ISODate ISO 8601 extended format: either YYYY-MM-DD for dates or YYYY-MM-DDTHH:MM:SS, YYYY-MM-DDTHH:MM:SSTZD (e.g., 1997-07-16T19:20:30+01:00) for combined dates and times.
Qt.SystemLocaleShortDate The short format used by the operating system .
Qt.SystemLocaleLongDate The long format used by the operating system .
Qt.DefaultLocaleShortDate The short format specified by the application's locale .
Qt.DefaultLocaleLongDate The long format used by the application's locale .
Qt.SystemLocaleDate This enum value is deprecated. Use Qt.SystemLocaleShortDate instead (or Qt.SystemLocaleLongDate if you want long dates).
Qt.LocaleDate This enum value is deprecated. Use Qt.DefaultLocaleShortDate instead (or Qt.DefaultLocaleLongDate if you want long dates).
Qt.LocalDate This enum value is deprecated. Use Qt.SystemLocaleShortDate instead (or Qt.SystemLocaleLongDate if you want long dates).

Note

For ISODate formats, each Y , M and D represents a single digit of the year, month and day used to specify the date. Each H , M and S represents a single digit of the hour, minute and second used to specify the time. The presence of a literal T character is used to separate the date and time when both are specified.

PySide.QtCore.Qt.TextFormat

This enum is used in widgets that can display both plain text and rich text, e.g. PySide.QtGui.QLabel . It is used for deciding whether a text string should be interpreted as one or the other. This is normally done by passing one of the enum values to a setTextFormat() function.

Constant Description
Qt.PlainText The text string is interpreted as a plain text string.
Qt.RichText The text string is interpreted as a rich text string.
Qt.AutoText The text string is interpreted as for Qt.RichText if Qt.mightBeRichText() returns true, otherwise as Qt.PlainText .
Qt.LogText A special, limited text format which is only used by Q3TextEdit in an optimized mode.
PySide.QtCore.Qt.PenJoinStyle

This enum type defines the pen join styles supported by Qt, i.e. which joins between two connected lines can be drawn using PySide.QtGui.QPainter .

../../_images/qpen-bevel.png ../../_images/qpen-miter.png ../../_images/qpen-roundjoin.png
Qt.BevelJoin Qt.MiterJoin Qt.RoundJoin
Constant Description
Qt.MiterJoin The outer edges of the lines are extended to meet at an angle, and this area is filled.
Qt.BevelJoin The triangular notch between the two lines is filled.
Qt.RoundJoin A circular arc between the two lines is filled.
Qt.SvgMiterJoin A miter join corresponding to the definition of a miter join in the SVG 1.2 Tiny specification.
PySide.QtCore.Qt.GestureFlag

This enum type describes additional flags that can be used when subscribing to a gesture.

Constant Description
Qt.DontStartGestureOnChildren By default gestures can start on the widget or over any of its children. Use this flag to disable this and allow a gesture to start on the widget only.
Qt.ReceivePartialGestures Allows any ignored gesture events to be propagated to parent widgets which have specified this hint. By default only gestures that are in the Qt.GestureStarted state are propagated and the widget always gets the full gesture sequence starting with a gesture in the Qt.GestureStarted state and ending with a gesture in the Qt.GestureFinished or Qt.GestureCanceled states.
Qt.IgnoredGesturesPropagateToParent Since Qt 4.7, this flag allows you to fine-tune gesture event propagation. By setting the flag when grabbing a gesture all ignored partial gestures will propagate to their parent items.

QWidget.grabGesture() QGraphicsObject.grabGesture()

Note

This enum was introduced or modified in Qt 4.6

PySide.QtCore.Qt.CaseSensitivity
Constant Description
Qt.CaseInsensitive  
Qt.CaseSensitive  
PySide.QtCore.Qt.EventPriority

This enum can be used to specify event priorities.

Constant Description
Qt.HighEventPriority Events with this priority are sent before events with NormalEventPriority or LowEventPriority .
Qt.NormalEventPriority Events with this priority are sent after events with HighEventPriority , but before events with LowEventPriority .
Qt.LowEventPriority Events with this priority are sent after events with HighEventPriority or NormalEventPriority .

Note that these values are provided purely for convenience, since event priorities can be any value between INT_MAX and INT_MIN , inclusive. For example, you can define custom priorities as being relative to each other:

# An important event
ImportantEventPriority = Qt.HighEventPriority
# A more important event
MoreImportantEventPriority = ImportantEventPriority + 1
# A critical event
CriticalEventPriority = 100 * MoreImportantEventPriority
# Not that important
StatusEventPriority = Qt.LowEventPriority
# These are less important than Status events
IdleProcessingDoneEventPriority = StatusEventPriority - 1
PySide.QtCore.Qt.ImageConversionFlag

The options marked “(default)” are set if no other values from the list are included (since the defaults are zero):

Color/Mono preference (ignored for PySide.QtGui.QBitmap ):

Constant Description
Qt.AutoColor (default) - If the image has PySide.QtGui.QImage.depth() 1 and contains only black and white pixels, the pixmap becomes monochrome.
Qt.ColorOnly The pixmap is dithered/converted to the native display depth .
Qt.MonoOnly The pixmap becomes monochrome. If necessary, it is dithered using the chosen dithering algorithm.

Dithering mode preference for RGB channels:

Constant Description
Qt.DiffuseDither (default) - A high-quality dither.
Qt.OrderedDither A faster, more ordered dither.
Qt.ThresholdDither No dithering; closest color is used.

Dithering mode preference for alpha channel:

Constant Description
Qt.ThresholdAlphaDither (default) - No dithering.
Qt.OrderedAlphaDither A faster, more ordered dither.
Qt.DiffuseAlphaDither A high-quality dither.

Color matching versus dithering preference:

Constant Description
Qt.PreferDither (default when converting to a pixmap) - Always dither 32-bit images when the image is converted to 8 bits.
Qt.AvoidDither (default when converting for the purpose of saving to file) - Dither 32-bit images only if the image has more than 256 colors and it is being converted to 8 bits.
Qt.NoOpaqueDetection Do not check whether the image contains non-opaque pixels. Use this if you know that the image is semi-transparent and you want to avoid the overhead of checking the pixels in the image until a non-opaque pixel is found, or if you want the pixmap to retain an alpha channel for some other reason. If the image has no alpha channel this flag has no effect.
PySide.QtCore.Qt.GestureState

This enum type describes the state of a gesture.

Constant Description
Qt.GestureStarted A continuous gesture has started.
Qt.GestureUpdated A gesture continues.
Qt.GestureFinished A gesture has finished.
Qt.GestureCanceled A gesture was canceled.

Note

This enum was introduced or modified in Qt 4.6

PySide.QtCore.Qt.BGMode

Background mode:

Constant Description
Qt.TransparentMode  
Qt.OpaqueMode  
PySide.QtCore.Qt.ConnectionType

This enum describes the types of connection that can be used between signals and slots. In particular, it determines whether a particular signal is delivered to a slot immediately or queued for delivery at a later time.

Constant Description
Qt.AutoConnection (default) If the signal is emitted from a different thread than the receiving object, the signal is queued, behaving as Qt.QueuedConnection . Otherwise, the slot is invoked directly, behaving as Qt.DirectConnection . The type of connection is determined when the signal is emitted.
Qt.DirectConnection The slot is invoked immediately, when the signal is emitted.
Qt.QueuedConnection The slot is invoked when control returns to the event loop of the receiver’s thread. The slot is executed in the receiver’s thread.
Qt.BlockingQueuedConnection Same as QueuedConnection , except the current thread blocks until the slot returns. This connection type should only be used where the emitter and receiver are in different threads. Note: Violating this rule can cause your application to deadlock.
Qt.UniqueConnection Same as AutoConnection , but the connection is made only if it does not duplicate an existing connection. i.e., if the same signal is already connected to the same slot for the same pair of objects, then the connection will fail. This connection type was introduced in Qt 4.6.
Qt.AutoCompatConnection The default type when Qt 3 support is enabled. Same as AutoConnection but will also cause warnings to be output in certain situations. See Compatibility Signals and Slots for further information.

With queued connections, the parameters must be of types that are known to Qt’s meta-object system, because Qt needs to copy the arguments to store them in an event behind the scenes. If you try to use a queued connection and get the error message:

QObject::connect: Cannot queue arguments of type 'MyType'

Call qRegisterMetaType() to register the data type before you establish the connection.

When using signals and slots with multiple threads, see Signals and Slots Across Threads .

PySide.QtCore.Qt.AlignmentFlag

This enum type is used to describe alignment. It contains horizontal and vertical flags that can be combined to produce the required effect.

The Qt.TextElideMode enum can also be used in many situations to fine-tune the appearance of aligned text.

The horizontal flags are:

Constant Description
Qt.AlignLeft Aligns with the left edge.
Qt.AlignRight Aligns with the right edge.
Qt.AlignHCenter Centers horizontally in the available space.
Qt.AlignJustify Justifies the text in the available space.

The vertical flags are:

Constant Description

Qt.AlignBottom Aligns with the bottom.
Qt.AlignVCenter Centers vertically in the available space.

You can use only one of the horizontal flags at a time. There is one two-dimensional flag:

Constant Description
Qt.AlignCenter Centers in both dimensions.

You can use at most one horizontal and one vertical flag at a time. Qt.AlignCenter counts as both horizontal and vertical.

Three enum values are useful in applications that can be run in right-to-left mode:

Constant Description
Qt.AlignAbsolute If the widget’s layout direction is Qt.RightToLeft (instead of Qt.LeftToRight , the default), Qt.AlignLeft refers to the right edge and Qt.AlignRight to the left edge. This is normally the desired behavior. If you want Qt.AlignLeft to always mean “left” and Qt.AlignRight to always mean “right”, combine the flag with Qt.AlignAbsolute .
Qt.AlignLeading Synonym for Qt.AlignLeft .
Qt.AlignTrailing Synonym for Qt.AlignRight .

Masks:

Constant Description
Qt.AlignHorizontal_Mask  
Qt.AlignVertical_Mask  

Conflicting combinations of flags have undefined meanings.

PySide.QtCore.Qt.ContextMenuPolicy

This enum type defines the various policies a widget can have with respect to showing a context menu.

Constant Description
Qt.NoContextMenu the widget does not feature a context menu, context menu handling is deferred to the widget’s parent.
Qt.PreventContextMenu the widget does not feature a context menu, and in contrast to NoContextMenu, the handling is not deferred to the widget’s parent. This means that all right mouse button events are guaranteed to be delivered to the widget itself through mousePressEvent(), and mouseReleaseEvent().
Qt.DefaultContextMenu the widget’s QWidget.contextMenuEvent() handler is called.
Qt.ActionsContextMenu the widget displays its QWidget.actions() as context menu.
Qt.CustomContextMenu the widget emits the QWidget.customContextMenuRequested() signal.

Qt.TopDockWidgetArea  
Qt.BottomDockWidgetArea  
Qt.AllDockWidgetAreas  
Qt.NoDockWidgetArea  
PySide.QtCore.Qt.UIEffect

This enum describes the available UI effects.

By default, Qt will try to use the platform specific desktop settings for each effect. Use the QApplication.setDesktopSettingsAware() function (passing false as argument) to prevent this, and the QApplication.setEffectEnabled() to enable or disable a particular effect.

Note that all effects are disabled on screens running at less than 16-bit color depth.

Constant Description

Qt.NavigationModeKeypadDirectional Qt.Key_Up , Qt.Key_Down , Qt.Key_Left and Qt.Key_Right are used to change focus.
Qt.NavigationModeCursorAuto The mouse cursor is used to change focus, it is displayed only on non touchscreen devices. The keypad is used to implement a virtual cursor, unless the device has an analog mouse type of input device (e.g. touchpad). This is the recommended setting for an application such as a web browser that needs pointer control on both touch and non-touch devices.
Qt.NavigationModeCursorForceVisible The mouse cursor is used to change focus, it is displayed regardless of device type. The keypad is used to implement a virtual cursor, unless the device has an analog mouse type of input device (e.g. touchpad)

Note

: in 4.6, cursor navigation is only implemented for Symbian OS. On other platforms, it behaves as NavigationModeNone .

PySide.QtCore.Qt.FillRule

Specifies which method should be used to fill the paths and polygons.

Constant Description
Qt.OddEvenFill Specifies that the region is filled using the odd even fill rule. With this rule, we determine whether a point is inside the shape by using the following method. Draw a horizontal line from the point to a location outside the shape, and count the number of intersections. If the number of intersections is an odd number, the point is inside the shape. This mode is the default.
Qt.WindingFill Specifies that the region is filled using the non zero winding rule. With this rule, we determine whether a point is inside the shape by using the following method. Draw a horizontal line from the point to a location outside the shape. Determine whether the direction of the line at each intersection point is up or down. The winding number is determined by summing the direction of each intersection. If the number is non zero, the point is inside the shape. This fill mode can also in most cases be considered as the intersection of closed shapes.
PySide.QtCore.Qt.MaskMode

This enum specifies the behavior of the QPixmap.createMaskFromColor() and QImage.createMaskFromColor() functions.

Constant Description
Qt.MaskInColor Creates a mask where all pixels matching the given color are opaque.

Specifies the direction of Qt’s layouts and text handling.

Constant Description
Qt.LeftToRight Left-to-right layout.
Qt.RightToLeft Right-to-left layout.
Qt.LayoutDirectionAuto Automatic layout.

Right-to-left layouts are necessary for certain languages, notably Arabic and Hebrew.

LayoutDirectionAuto serves two purposes. When used in conjunction with widgets and layouts, it will imply to use the layout direction set on the parent widget or PySide.QtGui.QApplication . This has the same effect as QWidget.unsetLayoutDirection() .

When LayoutDirectoinAuto is used in conjunction with text layouting, it will imply that the text directionality is determined from the content of the string to be layouted.

PySide.QtCore.Qt.ApplicationAttribute

This enum describes attributes that change the behavior of application-wide features. These are enabled and disabled using QCoreApplication.setAttribute() , and can be tested for with QCoreApplication.testAttribute() .

Constant Description
Qt.AA_ImmediateWidgetCreation Ensures that widgets are created as soon as they are constructed. By default, resources for widgets are allocated on demand to improve efficiency and minimize resource usage. Setting or clearing this attribute affects widgets constructed after the change. Setting it tells Qt to create toplevel windows immediately. Therefore, if it is important to minimize resource consumption, do not set this attribute.
Qt.AA_MSWindowsUseDirect3DByDefault This value is obsolete and has no effect.
Qt.AA_DontShowIconsInMenus Actions with the Icon property won’t be shown in any menus unless specifically set by the QAction.iconVisibleInMenu property. Menus that are currently open or menus already created in the native Mac OS X menubar may not pick up a change in this attribute. Changes in the QAction.iconVisibleInMenu property will always be picked up.
Qt.AA_NativeWindows Ensures that widgets have native windows.
Qt.AA_DontCreateNativeWidgetSiblings Ensures that siblings of native widgets stay non-native unless specifically set by the Qt.WA_NativeWindow attribute.
Qt.AA_MacPluginApplication Stops the Qt mac application from doing specific initializations that do not necessarily make sense when using Qt to author a plugin. This includes avoiding loading our nib for the main menu and not taking possession of the native menu bar. When setting this attribute to true will also set the AA_DontUseNativeMenuBar attribute to true.
Qt.AA_DontUseNativeMenuBar All menubars created while this attribute is set to true won’t be used as a native menubar (e.g, the menubar at the top of the main screen on Mac OS X or at the bottom in Windows CE).
Qt.AA_MacDontSwapCtrlAndMeta On Mac OS X by default, Qt swaps the Control and Meta (Command) keys (i.e., whenever Control is pressed, Qt sends Meta, and whenever Meta is pressed Control is sent). When this attribute is true, Qt will not do the flip. QKeySequence::StandardShortcuts will also flip accordingly (i.e., QKeySequence.Copy will be Command+C on the keyboard regardless of the value set, though what is output for QKeySequence::toString( QKeySequence.PortableText ) will be different).
Qt.AA_S60DontConstructApplicationPanes Stops Qt from initializing the S60 status pane and softkey pane on Symbian. This is useful to save memory and reduce startup time for applications that will run in fullscreen mode during their whole lifetime. This attribute must be set before PySide.QtGui.QApplication is constructed.

By default in Symbian^3, a separate editing window is opened on top of an application. This is exactly like editing on previous versions of Symbian behave. When this attribute is true, a virtual keyboard window is shown on top of application and it is ensured that the focused text widget is visible. This is only supported in Symbian^3. (internal)

PySide.QtCore.Qt.TextFlag

This enum type is used to define some modifier flags. Some of these flags only make sense in the context of printing:

Constant Description
Qt.TextSingleLine Treats all whitespace as spaces and prints just one line.
Qt.TextDontClip If it’s impossible to stay within the given bounds, it prints outside.
Qt.TextExpandTabs Makes the U+0009 (ASCII tab) character move to the next tab stop.
Qt.TextShowMnemonic Displays the string “&P” as P (see QButton for an example). For an ampersand, use “&&”.
Qt.TextWordWrap Breaks lines at appropriate points, e.g. at word boundaries.
Qt.TextWrapAnywhere Breaks lines anywhere, even within words.
Qt.TextHideMnemonic Same as Qt.TextShowMnemonic but doesn’t draw the underlines.
Qt.TextDontPrint Treat this text as “hidden” and don’t print it.
Qt.IncludeTrailingSpaces When this option is set, QTextLine.naturalTextWidth() and naturalTextRect() will return a value that includes the width of trailing spaces in the text; otherwise this width is excluded.
Qt.TextIncludeTrailingSpaces Same as IncludeTrailingSpaces
Qt.TextJustificationForced Ensures that text lines are justified.

Ensures that the longest variant is always used when computing the size of a multi-variant string. (Internal)

You can use as many modifier flags as you want, except that Qt.TextSingleLine and Qt.TextWordWrap cannot be combined.

Flags that are inappropriate for a given use are generally ignored.

PySide.QtCore.Qt.BrushStyle

This enum type defines the brush styles supported by Qt, i.e. the fill pattern of shapes drawn using PySide.QtGui.QPainter .

../../_images/brush-styles.png
Constant Description
Qt.NoBrush No brush pattern.
Qt.SolidPattern Uniform color.
Qt.Dense1Pattern Extremely dense brush pattern.
Qt.Dense2Pattern Very dense brush pattern.
Qt.Dense3Pattern Somewhat dense brush pattern.
Qt.Dense4Pattern Half dense brush pattern.
Qt.Dense5Pattern Somewhat sparse brush pattern.
Qt.Dense6Pattern Very sparse brush pattern.
Qt.Dense7Pattern Extremely sparse brush pattern.
Qt.HorPattern Horizontal lines.
Qt.VerPattern Vertical lines.
Qt.CrossPattern Crossing horizontal and vertical lines.
Qt.BDiagPattern Backward diagonal lines.
Qt.FDiagPattern Forward diagonal lines.
Qt.DiagCrossPattern Crossing diagonal lines.
Qt.LinearGradientPattern Linear gradient (set using a dedicated PySide.QtGui.QBrush constructor).
Qt.ConicalGradientPattern Conical gradient (set using a dedicated PySide.QtGui.QBrush constructor).
Qt.RadialGradientPattern Radial gradient (set using a dedicated PySide.QtGui.QBrush constructor).
Qt.TexturePattern Custom pattern (see QBrush.setTexture() ).
PySide.QtCore.Qt.WidgetAttribute

This enum type is used to specify various widget attributes. Attributes are set and cleared with QWidget.setAttribute() , and queried with QWidget.testAttribute() , although some have special convenience functions which are mentioned below.

Constant Description
Qt.WA_AcceptDrops Allows data from drag and drop operations to be dropped onto the widget (see QWidget.setAcceptDrops() ).
Qt.WA_AlwaysShowToolTips Enables tooltips for inactive windows.
Qt.WA_ContentsPropagated This flag is superfluous and obsolete; it no longer has any effect. Since Qt 4.1, all widgets that do not set WA_PaintOnScreen propagate their contents.
Qt.WA_CustomWhatsThis Indicates that the widget wants to continue operating normally in “What’s This?” mode. This is set by the widget’s author.
Qt.WA_DeleteOnClose Makes Qt delete this widget when the widget has accepted the close event (see QWidget.closeEvent() ).
Qt.WA_Disabled Indicates that the widget is disabled, i.e. it does not receive any mouse or keyboard events. There is also a getter functions QWidget.isEnabled() . This is set/cleared by the Qt kernel.
Qt.WA_DontShowOnScreen Indicates that the widget is hidden or is not a part of the viewable Desktop.
Qt.WA_ForceDisabled Indicates that the widget is explicitly disabled, i.e. it will remain disabled even when all its ancestors are set to the enabled state. This implies WA_Disabled . This is set/cleared by QWidget.setEnabled() and QWidget.setDisabled() .
Qt.WA_ForceUpdatesDisabled Indicates that updates are explicitly disabled for the widget; i.e. it will remain disabled even when all its ancestors are set to the updates-enabled state. This implies WA_UpdatesDisabled . This is set/cleared by QWidget.setUpdatesEnabled() .
Qt.WA_GroupLeader This attribute has been deprecated. Use QWidget.windowModality instead.
Qt.WA_Hover Forces Qt to generate paint events when the mouse enters or leaves the widget. This feature is typically used when implementing custom styles; see the Styles example for details.
Qt.WA_InputMethodEnabled Enables input methods for Asian languages. Must be set when creating custom text editing widgets. On Windows CE and Symbian this flag can be used in addition to QApplication.autoSipEnabled to automatically display the SIP when entering a widget.
Qt.WA_KeyboardFocusChange Set on a toplevel window when the users changes focus with the keyboard (tab, backtab, or shortcut).
Qt.WA_KeyCompression Enables key event compression if set, and disables it if not set. By default key compression is off, so widgets receive one key press event for each key press (or more, since autorepeat is usually on). If you turn it on and your program doesn’t keep up with key input, Qt may try to compress key events so that more than one character can be processed in each event. For example, a word processor widget might receive 2, 3 or more characters in each QKeyEvent.text() , if the layout recalculation takes too long for the CPU. If a widget supports multiple character unicode input, it is always safe to turn the compression on. Qt performs key event compression only for printable characters. Qt.Modifier keys, cursor movement keys, function keys and miscellaneous action keys (e.g. Escape, Enter, Backspace, PrintScreen) will stop key event compression, even if there are more compressible key events available. Platforms other than Mac and X11 do not support this compression, in which case turning it on will have no effect. This is set/cleared by the widget’s author.
Qt.WA_LayoutOnEntireRect Indicates that the widget wants PySide.QtGui.QLayout to operate on the entire QWidget.rect() , not only on QWidget.contentsRect() . This is set by the widget’s author.
Qt.WA_LayoutUsesWidgetRect Ignore the layout item rect from the style when laying out this widget with PySide.QtGui.QLayout . This makes a difference in QMacStyle and PySide.QtGui.QPlastiqueStyle for some widgets.
Qt.WA_MacNoClickThrough When a widget that has this attribute set is clicked, and its window is inactive, the click will make the window active but won’t be seen by the widget. Typical use of this attribute is on widgets with “destructive” actions, such as a “Delete” button. WA_MacNoClickThrough also applies to all child widgets of the widget that has it set.
Qt.WA_MacOpaqueSizeGrip Indicates that the native Carbon size grip should be opaque instead of transparent (the default). This attribute is only applicable to Mac OS X and is set by the widget’s author.
Qt.WA_MacShowFocusRect Indicates that this widget should get a PySide.QtGui.QFocusFrame around it. Some widgets draw their own focus halo regardless of this attribute. Not that the QWidget.focusPolicy also plays the main role in whether something is given focus or not, this only controls whether or not this gets the focus frame. This attribute is only applicable to Mac OS X.
Qt.WA_MacNormalSize Indicates the widget should have the normal size for widgets in Mac OS X. This attribute is only applicable to Mac OS X.
Qt.WA_MacSmallSize Indicates the widget should have the small size for widgets in Mac OS X. This attribute is only applicable to Mac OS X.
Qt.WA_MacMiniSize Indicates the widget should have the mini size for widgets in Mac OS X. This attribute is only applicable to Mac OS X.
Qt.WA_MacVariableSize Indicates the widget can choose between alternative sizes for widgets to avoid clipping. This attribute is only applicable to Mac OS X.
Qt.WA_MacBrushedMetal Indicates the widget should be drawn in the brushed metal style as supported by the windowing system. This attribute is only applicable to Mac OS X.
Qt.WA_Mapped Indicates that the widget is mapped on screen. This is set/cleared by the Qt kernel.
Qt.WA_MouseNoMask Makes the widget receive mouse events for the entire widget regardless of the currently set mask, overriding QWidget.setMask() . This is not applicable for top-level windows.
Qt.WA_MouseTracking Indicates that the widget has mouse tracking enabled. See QWidget.mouseTracking .
Qt.WA_Moved Indicates that the widget has an explicit position. This is set/cleared by QWidget.move() and by QWidget.setGeometry() .
Qt.WA_MSWindowsUseDirect3D This value is obsolete and has no effect.
Qt.WA_NoBackground This value is obsolete. Use WA_OpaquePaintEvent instead.
Qt.WA_NoChildEventsForParent Indicates that the widget does not want ChildAdded or ChildRemoved events sent to its parent. This is rarely necessary but can help to avoid automatic insertion widgets like splitters and layouts. This is set by a widget’s author.
Qt.WA_NoChildEventsFromChildren Indicates that the widget does not want to receive ChildAdded or ChildRemoved events sent from its children. This is set by a widget’s author.
Qt.WA_NoMouseReplay Used for pop-up widgets. Indicates that the most recent mouse press event should not be replayed when the pop-up widget closes. The flag is set by the widget’s author and cleared by the Qt kernel every time the widget receives a new mouse event.
Qt.WA_NoMousePropagation Prohibits mouse events from being propagated to the widget’s parent. This attribute is disabled by default.
Qt.WA_TransparentForMouseEvents When enabled, this attribute disables the delivery of mouse events to the widget and its children. Mouse events are delivered to other widgets as if the widget and its children were not present in the widget hierarchy; mouse clicks and other events effectively “pass through” them. This attribute is disabled by default.
Qt.WA_NoSystemBackground Indicates that the widget has no background, i.e. when the widget receives paint events, the background is not automatically repainted. Note: Unlike WA_OpaquePaintEvent , newly exposed areas are never filled with the background (e.g., after showing a window for the first time the user can see “through” it until the application processes the paint events). This flag is set or cleared by the widget’s author.
Qt.WA_OpaquePaintEvent Indicates that the widget paints all its pixels when it receives a paint event. Thus, it is not required for operations like updating, resizing, scrolling and focus changes to erase the widget before generating paint events. The use of WA_OpaquePaintEvent provides a small optimization by helping to reduce flicker on systems that do not support double buffering and avoiding computational cycles necessary to erase the background prior to painting. Note: Unlike WA_NoSystemBackground , WA_OpaquePaintEvent makes an effort to avoid transparent window backgrounds. This flag is set or cleared by the widget’s author.
Qt.WA_OutsideWSRange Indicates that the widget is outside the valid range of the window system’s coordinate system. A widget outside the valid range cannot be mapped on screen. This is set/cleared by the Qt kernel.
Qt.WA_PaintOnScreen Indicates that the widget wants to draw directly onto the screen. Widgets with this attribute set do not participate in composition management, i.e. they cannot be semi-transparent or shine through semi-transparent overlapping widgets. Note: This flag is only supported on X11 and it disables double buffering. On Qt for Embedded Linux, the flag only works when set on a top-level widget and it relies on support from the active screen driver. This flag is set or cleared by the widget’s author. To render outside of Qt’s paint system, e.g., if you require native painting primitives, you need to reimplement QWidget.paintEngine() to return 0 and set this flag.
Qt.WA_PaintOutsidePaintEvent Makes it possible to use PySide.QtGui.QPainter to paint on the widget outside PySide.QtGui.QWidget.paintEvent() . This flag is not supported on Windows, Mac OS X or Embedded Linux. We recommend that you use it only when porting Qt 3 code to Qt 4.
Qt.WA_PaintUnclipped Makes all painters operating on this widget unclipped. Children of this widget or other widgets in front of it do not clip the area the painter can paint on. This flag is only supported for widgets with the WA_PaintOnScreen flag set. The preferred way to do this in a cross platform way is to create a transparent widget that lies in front of the other widgets.
Qt.WA_PendingMoveEvent Indicates that a move event is pending, e.g., when a hidden widget was moved. This flag is set or cleared by the Qt kernel.
Qt.WA_PendingResizeEvent Indicates that a resize event is pending, e.g., when a hidden widget was resized. This flag is set or cleared by the Qt kernel.
Qt.WA_QuitOnClose Makes Qt quit the application when the last widget with the attribute set has accepted closeEvent(). This behavior can be modified with the QApplication.quitOnLastWindowClosed property. By default this attribute is set for all widgets of type Qt.Window .
Qt.WA_Resized Indicates that the widget has an explicit size. This flag is set or cleared by QWidget.resize() and QWidget.setGeometry() .
Qt.WA_RightToLeft Indicates that the layout direction for the widget is right to left.
Qt.WA_SetCursor Indicates that the widget has a cursor of its own. This flag is set or cleared by QWidget.setCursor() and QWidget.unsetCursor() .
Qt.WA_SetFont Indicates that the widget has a font of its own. This flag is set or cleared by QWidget.setFont() .
Qt.WA_SetPalette Indicates that the widget has a palette of its own. This flag is set or cleared by QWidget.setPalette() .
Qt.WA_SetStyle Indicates that the widget has a style of its own. This flag is set or cleared by QWidget.setStyle() .
Qt.WA_ShowModal This attribute has been deprecated. Use QWidget.windowModality instead.
Qt.WA_StaticContents Indicates that the widget contents are north-west aligned and static. On resize, such a widget will receive paint events only for parts of itself that are newly visible. This flag is set or cleared by the widget’s author.
Qt.WA_StyleSheet Indicates that the widget is styled using a style sheet .
Qt.WA_TranslucentBackground Indicates that the widget should have a translucent background, i.e., any non-opaque regions of the widgets will be translucent because the widget will have an alpha channel. Setting this flag causes WA_NoSystemBackground to be set. On Windows the widget also needs the Qt.FramelessWindowHint window flag to be set. This flag is set or cleared by the widget’s author.
Qt.WA_UnderMouse Indicates that the widget is under the mouse cursor. The value is not updated correctly during drag and drop operations. There is also a getter function, QWidget.underMouse() . This flag is set or cleared by the Qt kernel.
Qt.WA_UpdatesDisabled Indicates that updates are blocked (including the system background). This flag is set or cleared by the Qt kernel.

Warning

This flag must never be set or cleared by the widget’s author.

Constant Description
Qt.WA_WindowModified Indicates that the window is marked as modified. On some platforms this flag will do nothing, on others (including Mac OS X and Windows) the window will take a modified appearance. This flag is set or cleared by QWidget.setWindowModified() .
Qt.WA_WindowPropagation Makes a toplevel window inherit font and palette from its parent.
Qt.WA_MacAlwaysShowToolWindow On Mac OS X, show the tool window even when the application is not active. By default, all tool windows are hidden when the application is inactive.
Qt.WA_SetLocale Indicates the locale should be taken into consideration in the widget.
Qt.WA_StyledBackground Indicates the widget should be drawn using a styled background.
Qt.WA_ShowWithoutActivating Show the widget without making it active.
Qt.WA_NativeWindow Indicates that a native window is created for the widget. Enabling this flag will also force a native window for the widget’s ancestors unless Qt.WA_DontCreateNativeAncestors is set.
Qt.WA_DontCreateNativeAncestors Indicates that the widget’s ancestors are kept non-native even though the widget itself is native.
Qt.WA_X11NetWmWindowTypeDesktop Adds _NET_WM_WINDOW_TYPE_DESKTOP to the window’s _NET_WM_WINDOW_TYPE X11 window property. See http://standards.freedesktop.org/wm-spec/ for more details. This attribute has no effect on non-X11 platforms.

Qt.WA_MacFrameworkScaled Enables resolution independence aware mode on Mac when using Carbon. This attribute has no effect on Cocoa. The attribute is off by default and can be enabled on a per-window basis.
Qt.WA_AcceptTouchEvents Allows touch events (see PySide.QtGui.QTouchEvent ) to be sent to the widget. Must be set on all widgets that can handle touch events. Without this attribute set, events from a touch device will be sent as mouse events.
Qt.WA_TouchPadAcceptSingleTouchEvents Allows touchpad single touch events to be sent to the widget.
Qt.WA_MergeSoftkeys Allows widget to merge softkeys with parent widget, i.e. widget can set only one softkeys and request softkey implementation to take rest of the softkeys from the parent. Note parents are traversed until WA_MergeSoftkeys is not set. See also Qt.WA_MergeSoftkeysRecursively This attribute currently has effect only on Symbian platforms
Qt.WA_MergeSoftkeysRecursively Allows widget to merge softkeys recursively with all parents. If this attribute is set, the widget parents are traversed until window boundary (widget without parent or dialog) is found. This attribute currently has effect only on Symbian platforms
