PySide.QtCore.Qt. WindowType ¶

此枚举类型用于为 Widget 指定各种窗口系统特性。它们相当不寻常，但在某些情况下是必要的。其中一些标志从属底层窗口管理器是否支持它们。

主要类型是

常量	描述
Qt.Widget	这是默认类型对于 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 窗口。
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() ，或 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 属性。
Qt.ToolTip	指示 Widget 是工具提示。这在内部使用以实现 tooltips .
Qt.SplashScreen	指示窗口是闪屏。这是默认类型对于 PySide.QtGui.QSplashScreen .
Qt.Desktop	Indicates that this widget is the desktop. This is the type for PySide.QtGui.QDesktopWidget .
Qt.SubWindow	指示此 Widget 是子窗口，譬如 PySide.QtGui.QMdiSubWindow 小部件。

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:

常量	描述
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.

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.

常量	描述
Qt.CustomizeWindowHint	关闭默认窗口标题提示。
Qt.WindowTitleHint	赋予窗口标题栏。
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.

Obsolete flags:

PySide.QtCore.Qt. DateFormat ¶

常量	描述
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() 了解更多信息。
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.LocalDate	This enum value is deprecated. 使用 Qt.SystemLocaleShortDate instead (or Qt.SystemLocaleLongDate if you want long dates).

注意

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.

常量	描述
Qt.PlainText	文本字符串被解释成纯文本字符串。
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 .

PySide.QtCore.Qt. ImageConversionFlag ¶

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

彩色/单色首选 (被忽略对于 PySide.QtGui.QBitmap ):

常量	描述
Qt.AutoColor	(默认) - 若图像有 PySide.QtGui.QImage.depth() 1 且只包含黑色和白色像素，像素图变为单色。
Qt.ColorOnly	像素图抖动/转换为 native display depth .
Qt.MonoOnly	像素图变成单色。若有必要，使用所选抖动算法进行抖动。

Dithering mode preference for RGB channels:

常量	描述

Qt.OrderedDither	A faster, more ordered dither.
Qt.ThresholdDither	没有抖动；使用最接近的颜色。

Dithering mode preference for alpha channel:

常量	描述
Qt.ThresholdAlphaDither	(默认) - 没有抖动。
Qt.OrderedAlphaDither	A faster, more ordered dither.
Qt.DiffuseAlphaDither	A high-quality dither.

颜色匹配 vs 抖动偏好：

常量	描述

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.

Don't do any format conversions on the image. Can be useful when converting a PySide.QtGui.QImage 到 PySide.QtGui.QPixmap for a one-time rendering operation for example.

PySide.QtCore.Qt. CursorMoveStyle ¶

此枚举描述文本光标的可用移动样式。选项：

常量	描述
Qt.LogicalMoveStyle	Within a left-to-right text block, decrease cursor position when pressing left arrow key, increase cursor position when pressing the right arrow key. If the text block is right-to-left, the opposite behavior applies.
Qt.VisualMoveStyle	Pressing the left arrow key will always cause the cursor to move left, regardless of the text's writing direction. Pressing the right arrow key will always cause the cursor to move right.

PySide.QtCore.Qt. GestureState ¶

此枚举类型描述手势的状态。

常量	描述
Qt.GestureStarted	连续手势已开始。

PySide.QtCore.Qt. ConnectionType ¶

此枚举描述可以用于信号和槽之间的连接类型。尤其，它确定是把特定信号立即交付给槽，还是在以后队列交付。

常量	描述
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	槽被援引当控制返回给接收者线程的事件循环时。槽在接收者线程中执行。
Qt.BlockingQueuedConnection	如同 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. 注意： Violating this rule can cause your application to deadlock.
Qt.UniqueConnection	如同 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.

采用队列连接，参数类型必须是 Qt 元对象系统知道的，因为 Qt 需要拷贝自变量以存储它们在幕后事件中。若试着队列排队连接并获得错误消息：

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

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

当使用信号和槽采用多个线程时，见 信号和槽跨线程 .

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() .

常量	描述
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	此值已过时且不起作用。
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 属性。
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.
Qt.AA_S60DisablePartialScreenInputMode	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 false, a non-fullscreen virtual keyboard window is shown on top of application and it is ensured that the focused text input widget is visible. The auto-translation of input widget is only supported for applications based on PySide.QtGui.QGraphicsView , but the non-fullscreen virtual keyboard will work for any kind of application (i.e. QWidgets-based). By default this attribute is true. This attribute must be set after PySide.QtGui.QApplication is constructed. This is only supported in Symbian^3 and later Symbian releases.
Qt.AA_X11InitThreads	Calls XInitThreads() as part of the PySide.QtGui.QApplication construction in order to make Xlib calls thread-safe. This attribute must be set before PySide.QtGui.QApplication is constructed.
Qt.AA_CaptureMultimediaKeys	Enables application to receive multimedia key events (play, next, previous etc). This includes also external sources such as headsets. Application can not use Remote Control framework on Symbian if this attribute is set. On Symbian, multimedia key event routing may vary between different devices. For example, application on background may receive multimedia key events only if it has active audio stream i.e. it is playing music or video. This attribute must be set before PySide.QtGui.QApplication is constructed. This attribute is only supported in Symbian platform.

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:

常量	描述
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 (见 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	如同 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	如同 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 .

常量	描述
Qt.NoBrush	没有笔刷图案。
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	自定义图案 (见 QBrush.setTexture() ).

PySide.QtGui.QBrush

PySide.QtCore.Qt. WidgetAttribute ¶

此枚举类型用于指定各种 Widget 属性。属性被设置和清零采用 QWidget.setAttribute() , and queried with QWidget.testAttribute() , although some have special convenience functions which are mentioned below.

常量	描述
Qt.WA_AcceptDrops	允许来自拖放操作的数据掉落到 Widget (见 QWidget.setAcceptDrops() ).
Qt.WA_AlwaysShowToolTips	为不活动窗口启用工具提示。
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	使 Qt 删除此 Widget 当小部件接受关闭事件时 (见 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	此属性已弃用。 使用 QWidget.windowModality 代替。
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 样式 范例了解细节。
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	启用键事件压缩，若设置；否则禁用，若未设置。默认情况下，键压缩是关闭的，因此每次按键 (或更多，因为自动重复通常是打开的) Widget 只接收一个键事件。若打开，而程序却跟不上键输入，Qt 可能试着去压缩键事件，以便在每个事件中可以处理多个字符。例如：字处理 Widget 可能接收 2、3 或更多字符，在各 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 PySide.QtGui.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	指示 Widget 已启用鼠标跟踪。见 QWidget.mouseTracking .
Qt.WA_Moved	指示 Widget 拥有明确位置。这的设置/清零通过 QWidget.move() and by QWidget.setGeometry() .
Qt.WA_MSWindowsUseDirect3D	此值已过时且不起作用。
Qt.WA_NoBackground	This value is obsolete. Use WA_OpaquePaintEvent 代替。
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	阻止将鼠标事件传播到 Widget 父级。此属性被禁用，默认情况下。
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	指示 Widget 没有背景 (即：当 Widget 接收描绘事件时，不自动重新绘制背景)。 注意： 不像 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. 注意： 不像 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. 注意： 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	此属性已弃用。 使用 QWidget.windowModality 代替。
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 样式表 .
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 窗口标志被设置。此标志由 Widget 的作者设置或清零。
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.

警告

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

常量	描述
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 被设置。
Qt.WA_DontCreateNativeAncestors	Indicates that the widget's ancestors are kept non-native even though the widget itself is native.
