Qt.FuzzyHit	The point at which input occurred can lie close to input-sensitive parts of the document.

PySide2.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 QWidget . Widgets of this type are child widgets if they have a parent, and independent windows if they have no parent. See also and .
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 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 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 sheet on macOS. Since using a sheet implies window modality, the recommended way is to use setWindowModality() ，或 open() , instead.
Qt.Drawer	指示小部件是 macOS 抽屉。
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 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 . On macOS, tool windows correspond to the NSPanel class of windows. This means that the window lives on a level above normal windows making 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 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 QSplashScreen .
Qt.Desktop	Indicates that this widget is the desktop. This is the type for QDesktopWidget .
Qt.SubWindow	指示此 Widget 是子窗口，譬如 QMdiSubWindow 小部件。
Qt.ForeignWindow	Indicates that this window object is a handle representing a native platform window created by another process or by manually using native code.
Qt.CoverWindow	Indicates that the window represents a cover window, which is shown when the application is minimized on some platforms.

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.

注意

The use of this flag is not recommended in multi-monitor environments. This is because the system will enforce that the window maintains its native size when moving it across screens. This is particularly undesirable when using monitors with different resolutions.

常量	描述
Qt.MSWindowsOwnDC	Gives the window its own display context on Windows.
Qt.BypassWindowManagerHint	This flag can be used to indicate to the platform plugin that “all” window manager protocols should be disabled. This flag will behave different depending on what operating system the application is running on and what window manager is running. The flag can be used to get a native window with no configuration set.
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 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.
Qt.NoDropShadowWindowHint	Disables window drop shadow on supporting platforms.

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 for it to work.
Qt.WindowMaximizeButtonHint	Adds a maximize button. On some platforms this implies for it to work.
Qt.WindowMinMaxButtonsHint	Adds a minimize and a maximize button. On some platforms this implies for it to work.
Qt.WindowCloseButtonHint	Adds a close button. On some platforms this implies for it to work.
Qt.WindowContextHelpButtonHint	Adds a context help button to dialogs. On some platforms this implies for it to work.
Qt.MacWindowToolBarButtonHint	On macOS adds a tool bar button (i.e., the oblong button that is on the top right of windows that have toolbars).
Qt.WindowFullscreenButtonHint	在 MacOS 添加全屏按钮。
Qt.BypassGraphicsProxyWidget	Prevents the window and its children from automatically embedding themselves into a 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	Adds a shade button in place of the minimize button if the underlying window manager supports it.
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 for this flag to work correctly.
Qt.WindowStaysOnBottomHint	Informs the window system that the window should stay on bottom of all other windows.

注意

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 macOS.

注意

在 Windows，这仅工作于无框或全屏窗口。

常量	描述
Qt.WindowTransparentForInput	Informs the window system that this window is used only for output (displaying something) and does not take input. Therefore input events should pass through as if it wasn’t there.
Qt.WindowOverridesSystemGestures	Informs the window system that this window implements its own set of gestures and that system level gestures, like for instance three-finger desktop switching, should be disabled.
Qt.WindowDoesNotAcceptFocus	Informs the window system that this window should not receive the input focus.
Qt.MaximizeUsingFullscreenGeometryHint	Informs the window system that when maximizing the window it should use as much of the available screen geometry as possible, including areas that may be covered by system UI such as status bars or application launchers. This may result in the window being placed under these system UIs, but does not guarantee it, depending on whether or not the platform supports it. When the flag is enabled the user is responsible for taking availableGeometry() into account, so that any UI elements in the application that require user interaction are not covered by system UI.
Qt.WindowType_Mask	A mask for extracting the window type part of the window flags.

PySide2.QtCore.Qt. WindowState ¶

此枚举类型用于指定顶层窗口的当前状态。

状态是

常量	描述
Qt.WindowNoState	窗口未设置状态 (在正常状态)。
Qt.WindowMinimized	窗口被最小化 (即：图标化)。
Qt.WindowMaximized	窗户被最大化，采用框架围绕它。
Qt.WindowFullScreen	窗口填充整个屏幕，没有任何框架围绕它。
Qt.WindowActive	窗口是活动窗口，即：它拥有键盘聚焦。

PySide2.QtCore.Qt. ApplicationState ¶

This enum type is used to specify the current state of the application.

状态是

常量	描述
Qt.ApplicationSuspended	The application is about to suspend. When entering this state, the application should save its state, cease all activities, and be prepared for code execution to stop. While suspended, the application can be killed at any time without further warnings (e.g. when low memory forces the OS to purge suspended applications).
Qt.ApplicationHidden	The application is hidden and runs in the background. This is the normal state for applications that need to do background processing, like playing music, while the user interacts with other applications. The application should free up all graphical resources when entering this state.
Qt.ApplicationInactive	The application is visible, but not selected to be in front. On desktop platforms, this typically means that the user activated another application. On mobile platforms, it is more common to enter this state when the OS is interrupting the user with e.g. incoming calls or SMS-messages. While in this state, consider reducing CPU-intensive tasks.
Qt.ApplicationActive	The application is visible and selected to be in front.

PySide2.QtCore.Qt. ScreenOrientation ¶

This enum type specifies the various orientations a screen might have.

常量	描述
Qt.PrimaryOrientation	The display’s primary orientation.
Qt.LandscapeOrientation	Landscape orientation, display width is greater than display height.
Qt.PortraitOrientation	Portrait orientation, display height is greater than display width, rotated 90 degree clockwise relative to landscape.
Qt.InvertedLandscapeOrientation	Inverted landscape orientation, rotated 180 degrees relative to landscape.
Qt.InvertedPortraitOrientation	Inverted portrait orientation, rotated 180 degrees relative to portrait.

PySide2.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 setAttribute() , and queried with 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 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 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 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 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 . This is set/cleared by setEnabled() and 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 . This is set/cleared by setUpdatesEnabled() .
Qt.WA_GroupLeader	此属性已弃用。 使用 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	启用用于亚洲语言的输入法。必须设置，当创建自定义文本编辑 Widget 时。
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 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. 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 QLayout to operate on the entire rect() , not only on 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 QLayout .
Qt.WA_MacNoClickThrough	此值已过时且不起作用。
Qt.WA_MacOpaqueSizeGrip	Indicates that the native size grip should be opaque instead of transparent (the default). This attribute is only applicable to macOS and is set by the widget’s author.
Qt.WA_MacShowFocusRect	Indicates that this widget should get a QFocusFrame around it. Some widgets draw their own focus halo regardless of this attribute. Not that the 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 macOS.
Qt.WA_MacNormalSize	Indicates the widget should have the normal size for widgets in macOS. This attribute is only applicable to macOS.
Qt.WA_MacSmallSize	Indicates the widget should have the small size for widgets in macOS. This attribute is only applicable to macOS.
Qt.WA_MacMiniSize	Indicates the widget should have the mini size for widgets in macOS. This attribute is only applicable to macOS.
Qt.WA_MacVariableSize	Indicates the widget can choose between alternative sizes for widgets to avoid clipping. This attribute is only applicable to macOS.
Qt.WA_MacBrushedMetal	此值已过时且不起作用。
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 setMask() . This is not applicable for top-level windows.
Qt.WA_MouseTracking	指示 Widget 已启用鼠标跟踪。见 mouseTracking .
Qt.WA_Moved	指示 Widget 拥有明确位置。这的设置/清零通过 move() and by setGeometry() .
Qt.WA_MSWindowsUseDirect3D	此值已过时且不起作用。
Qt.WA_NoBackground	This value is obsolete. Use 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	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 : Unlike , 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 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 : Unlike , 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 paintEngine() to return 0 and set this flag.
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 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 quitOnLastWindowClosed property. By default this attribute is set for all widgets of type Window .
Qt.WA_Resized	Indicates that the widget has an explicit size. This flag is set or cleared by resize() and 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 setCursor() and unsetCursor() .
Qt.WA_SetFont	Indicates that the widget has a font of its own. This flag is set or cleared by setFont() .
Qt.WA_SetPalette	Indicates that the widget has a palette of its own. This flag is set or cleared by setPalette() .
Qt.WA_SetStyle	Indicates that the widget has a style of its own. This flag is set or cleared by setStyle() .
Qt.WA_ShowModal	此属性已弃用。 使用 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 . is set whenever a widget is subject to a style sheet, even if the style sheet did not affect the widget appearance.
Qt.WA_StyleSheetTarget	Indicates that the widget appearance was modified by a 样式表 . will also be set. This value was introduced in Qt 5.12.
Qt.WA_TabletTracking	Indicates that the widget has tablet tracking enabled. See tabletTracking .
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 to be set. On Windows the widget also needs the 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, 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.
Qt.WA_WindowModified	Indicates that the window is marked as modified. On some platforms this flag will do nothing, on others (including macOS and Windows) the window will take a modified appearance. This flag is set or cleared by setWindowModified() .
Qt.WA_WindowPropagation	Makes a toplevel window inherit font, palette and locale from its parent.
Qt.WA_MacAlwaysShowToolWindow	On macOS, 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 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_X11NetWmWindowTypeUtility	Adds _NET_WM_WINDOW_TYPE_UTILITY 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. 注意 : Qt automatically sets this attribute for the 工具 window type.
Qt.WA_X11NetWmWindowTypeSplash	Adds _NET_WM_WINDOW_TYPE_SPLASH 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. 注意 : Qt automatically sets this attribute for the SplashScreen window type.
Qt.WA_X11NetWmWindowTypeDialog	Adds _NET_WM_WINDOW_TYPE_DIALOG 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. 注意 : Qt automatically sets this attribute for the Dialog and Sheet window types.
Qt.WA_X11NetWmWindowTypeDropDownMenu	Adds _NET_WM_WINDOW_TYPE_DROPDOWN_MENU 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. 注意 : Qt automatically sets this attribute for QMenu objects added to a QMenuBar .
Qt.WA_X11NetWmWindowTypePopupMenu	Adds _NET_WM_WINDOW_TYPE_POPUP_MENU 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. 注意 : Qt automatically sets this attribute for QMenu .
Qt.WA_X11NetWmWindowTypeToolTip	Adds _NET_WM_WINDOW_TYPE_TOOLTIP 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. 注意 : Qt automatically sets this attribute for the ToolTip window type.
Qt.WA_X11NetWmWindowTypeNotification	Adds _NET_WM_WINDOW_TYPE_NOTIFICATION 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_X11NetWmWindowTypeCombo	Adds _NET_WM_WINDOW_TYPE_COMBO to the window’s _NET_WM_WINDOW_TYPE X11 window property. See http://standards.freedesktop.org/wm-spec/ for more details.

Qt.WA_MacFrameworkScaled	此值已过时且不起作用。
Qt.WA_AcceptTouchEvents	Allows touch events (see 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_X11DoNotAcceptFocus	Asks the window manager to not give focus to this top level window. This attribute has no effect on non-X11 platforms.
Qt.WA_AlwaysStackOnTop	Since Qt 5.4, this value forces QOpenGLWidget and QQuickWidget to be drawn last, on top of other widgets. Ignored for other type of widgets. Setting this attribute breaks the stacking order, but allows having a semi-transparent OpenGL widget with other widgets visible underneath. It is strongly recommended to call update() on the widget’s top-level window after enabling or disabling this attribute.
Qt.WA_ContentsMarginsRespectsSafeArea	A QWidget respects the safe area margins of a window by incorporating the margins into its contents’ margins by default. This means, that a QLayout will use the content area of a widget for its layout, unless the attribute is set. This along with a contents margin of 0 can be used on the actual layout, to allow for example a background image to underlay the status bar and other system areas on an iOS device, while still allowing child widgets of that background to be inset based on the safe area.

PySide2.QtCore.Qt. ApplicationAttribute ¶

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

常量	描述
Qt.AA_DontShowIconsInMenus	Actions with the Icon property won’t be shown in any menus unless specifically set by the iconVisibleInMenu property. Menus that are currently open or menus already created in the native macOS menubar may not pick up a change in this attribute. Changes in the iconVisibleInMenu property will always be picked up.
Qt.AA_DontShowShortcutsInContextMenus	Actions with the Shortcut property won’t be shown in any shortcut menus unless specifically set by the shortcutVisibleInContextMenu property. This value was added in Qt 5.10.
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 WA_NativeWindow 属性。
Qt.AA_PluginApplication	Indicates that Qt is used to author a plugin. Depending on the operating system, it suppresses specific initializations that do not necessarily make sense in the plugin case. For example on macOS, this includes avoiding loading our nib for the main menu and not taking possession of the native menu bar. Setting this attribute to true will also set the attribute to true. It also disables native event filters. This attribute must be set before QGuiApplication constructed. This value was added in Qt 5.7.
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 macOS).
Qt.AA_MacDontSwapCtrlAndMeta	On macOS 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. StandardKey will also flip accordingly (i.e., Copy will be Command+C on the keyboard regardless of the value set, though what is output for toString() will be different).
Qt.AA_Use96Dpi	Assume the screen has a resolution of 96 DPI rather than using the OS-provided resolution. This will cause font rendering to be consistent in pixels-per-point across devices rather than defining 1 point as 1/72 inch.
Qt.AA_SynthesizeTouchForUnhandledMouseEvents	All mouse events that are not accepted by the application will be translated to touch events instead.
Qt.AA_SynthesizeMouseForUnhandledTouchEvents	All touch events that are not accepted by the application will be translated to left button mouse events instead. This attribute is enabled by default.
Qt.AA_UseHighDpiPixmaps	Make pixmap() generate high-dpi pixmaps that can be larger than the requested size. Such pixmaps will have devicePixelRatio() set to a value higher than 1. After setting this attribute, application code that uses pixmap sizes in layout geometry calculations should typically divide by devicePixelRatio() to get device-independent layout geometry.
Qt.AA_ForceRasterWidgets	Make top-level widgets use pure raster surfaces, and do not support non-native GL-based child widgets.
Qt.AA_UseDesktopOpenGL	Forces the usage of desktop OpenGL (for example, opengl32.dll or libGL.so ) on platforms that use dynamic loading of the OpenGL implementation. This attribute must be set before QGuiApplication is constructed. This value was added in Qt 5.3.
Qt.AA_UseOpenGLES	Forces the usage of OpenGL ES 2.0 or higher on platforms that use dynamic loading of the OpenGL implementation. This attribute must be set before QGuiApplication is constructed. This value was added in Qt 5.3.
Qt.AA_UseSoftwareOpenGL	Forces the usage of a software based OpenGL implementation on platforms that use dynamic loading of the OpenGL implementation. This will typically be a patched build of Mesa llvmpipe , providing OpenGL 2.1. The value may have no effect if no such OpenGL implementation is available. The default name of this library is opengl32sw.dll and can be overridden by setting the environment variable QT_OPENGL_DLL . See the platform-specific pages, for instance Qt for Windows, for more information. This attribute must be set before QGuiApplication is constructed. This value was added in Qt 5.4.
Qt.AA_ShareOpenGLContexts	Enables resource sharing between the OpenGL contexts used by classes like QOpenGLWidget and QQuickWidget . This allows sharing OpenGL resources, like textures, between QOpenGLWidget instances that belong to different top-level windows. This attribute must be set before QGuiApplication is constructed. This value was added in Qt 5.4.
Qt.AA_SetPalette	Indicates whether a palette was explicitly set on the QGuiApplication . This value was added in Qt 5.5.
Qt.AA_EnableHighDpiScaling	Enables high-DPI scaling in Qt on supported platforms (see also High DPI Displays). Supported platforms are X11, Windows and Android. Enabling makes Qt scale the main (device independent) coordinate system according to display scale factors provided by the operating system. This corresponds to setting the QT_AUTO_SCREEN​_SCALE_FACTOR environment variable to 1. This attribute must be set before QGuiApplication is constructed. This value was added in Qt 5.6.
Qt.AA_DisableHighDpiScaling	Disables high-DPI scaling in Qt, exposing window system coordinates. Note that the window system may do its own scaling, so this does not guarantee that devicePixelRatio() will be equal to 1. In addition, scale factors set by QT_SCALE_FACTOR will not be affected. This corresponds to setting the QT_AUTO_SCREEN​_SCALE_FACTOR environment variable to 0. This attribute must be set before QGuiApplication is constructed. This value was added in Qt 5.6.
Qt.AA_UseStyleSheetPropagationInWidgetStyles	By default, Qt Style Sheets disable regular QWidget palette and font propagation. When this flag is enabled, font and palette changes propagate as though the user had manually called the corresponding QWidget 方法。见 The Style Sheet Syntax - Inheritance for more details. This value was added in Qt 5.7.
Qt.AA_DontUseNativeDialogs	All dialogs created while this attribute is set to true won’t use the native dialogs provided by the platform. This value was added in Qt 5.7.
Qt.AA_SynthesizeMouseForUnhandledTabletEvents	All tablet events that are not accepted by the application will be translated to mouse events instead. This attribute is enabled by default. This value was added in Qt 5.7.
Qt.AA_CompressHighFrequencyEvents	Enables compression of certain frequent events. On the X11 windowing system, the default value is true, which means that MouseMove , TouchUpdate , and changes in window size and position will be combined whenever they occur more frequently than the application handles them, so that they don’t accumulate and overwhelm the application later. On Windows 8 and above the default value is also true, but it only applies to touch events. Mouse and window events remain unaffected by this flag. On other platforms, the default is false. (In the future, the compression feature may be implemented across platforms.) You can test the attribute to see whether compression is enabled. If your application needs to handle all events with no compression, you can unset this attribute. Notice that input events from tablet devices will not be compressed. See if you want these to be compressed as well. This value was added in Qt 5.7.
Qt.AA_CompressTabletEvents	Enables compression of input events from tablet devices. Notice that must be true for events compression to be enabled, and that this flag extends the former to tablet events. Currently supported on the X11 windowing system, Windows 8 and above. The default value is false. This value was added in Qt 5.10.
Qt.AA_DontCheckOpenGLContextThreadAffinity	When making a context current using QOpenGLContext , do not check that the QObject thread affinity 的 QOpenGLContext object is the same thread calling makeCurrent() . This value was added in Qt 5.8.
Qt.AA_DisableShaderDiskCache	Disables caching of shader program binaries on disk. By default Qt Quick, QPainter ‘s OpenGL backend, and any application using QOpenGLShaderProgram with one of its addCacheableShaderFromSource overloads will employ a disk-based program binary cache in either the shared or per-process cache storage location, on systems that support glProgramBinary() . In the unlikely event of this being problematic, set this attribute to disable all disk-based caching of shaders.
Qt.AA_DisableWindowContextHelpButton	禁用 WindowContextHelpButtonHint by default on Sheet and Dialog widgets. This hides the ? button on Windows, which only makes sense if you use QWhatsThis functionality. This value was added in Qt 5.10. In Qt 6, WindowContextHelpButtonHint will not be set by default.
Qt.AA_DisableSessionManager	禁用 QSessionManager . By default Qt will connect to a running session manager for a GUI application on supported platforms, use of a session manager may be redundant for system services. This attribute must be set before QGuiApplication is constructed. This value was added in 5.14
Qt.AA_DisableNativeVirtualKeyboard	When this attribute is set, the native on-screen virtual keyboard will not be shown automatically when a text input widget gains focus on a system without a physical keyboard. Currently supported on the Windows platform only. This value was added in 5.15

The following values are deprecated or obsolete:

常量	描述
Qt.AA_ImmediateWidgetCreation	This attribute is no longer fully supported in Qt 5. It 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_MacPluginApplication	This attribute has been deprecated. Use instead.
Qt.AA_MSWindowsUseDirect3DByDefault	此值已过时且不起作用。
Qt.AA_X11InitThreads	此值已过时且不起作用。

PySide2.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 QBitmap ):

常量	描述
Qt.AutoColor	(默认) - 若图像有 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。

抖动模式首选：

常量	描述
Qt.DiffuseDither	(默认) - 使用误差扩散的高质量抖动。
Qt.OrderedDither	更快，有序抖动。
Qt.ThresholdDither	没有抖动；使用最接近的颜色。

1 位 Alpha 蒙版的抖动模式首选：

常量	描述
Qt.ThresholdAlphaDither	(默认) - 没有抖动。
Qt.OrderedAlphaDither	更快，有序抖动。
Qt.DiffuseAlphaDither	使用误差扩散的高质量抖动。

颜色匹配 vs 抖动偏好：

常量	描述
Qt.PreferDither	始终抖动图像当转换为更小色彩空间时。
Qt.AvoidDither	Only dither to indexed formats if the source image uses more different colors than the size of the color table of the destination format.
Qt.AutoDither	(default) - Only dither when down-converting to 1 or 8-bit indexed formats.
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.
Qt.NoFormatConversion	Don’t do any format conversions on the image. Can be useful when converting a QImage 到 QPixmap for a one-time rendering operation for example. Note that a QPixmap not in the preferred format will be much slower as a paint device.

For dates and times separately, the same formats are matched and the unwanted parts are ignored. In particular, note that a time is not recognized without an accompanying date. When converting dates to string form, format dd MMM yyyy is used, for times the format is hh:mm:ss . For combined date and time, these are combined as dd MMM yyyy hh:mm:ss ±tzoff (omitting the optional leading day of the week from the first format recognized).

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.

Qt.DirectConnection	槽被立即援引当发射信号时。槽在发信号的线程中执行。
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 , except that the signalling thread blocks until the slot returns. This connection must not 被使用，若接收者活在发信号线程中，否则应用程序将死锁。
Qt.UniqueConnection	This is a flag that can be combined with any one of the above connection types, using a bitwise OR. When is set, connect() will fail if the connection already exists (i.e. if the same signal is already connected to the same slot for the same pair of objects). This flag was introduced in Qt 4.6.

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'
											

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

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.
