This enum type is used to describe alignment. It contains horizontal and vertical flags that can be combined to produce the required effect.
TextElideMode enum can also be used in many situations to fine-tune the appearance of aligned text.
水平标志:
常量 | 值 | 描述 |
---|---|---|
Qt::AlignLeft
|
0x0001
|
与左边缘对齐。 |
Qt::AlignRight
|
0x0002
|
与右边缘对齐。 |
Qt::AlignHCenter
|
0x0004
|
在可用空间水平居中。 |
Qt::AlignJustify
|
0x0008
|
Justifies the text in the available space. |
垂直标志:
常量 | 值 | 描述 |
---|---|---|
Qt::AlignTop
|
0x0020
|
与顶部对齐。 |
Qt::AlignBottom
|
0x0040
|
与底部对齐。 |
Qt::AlignVCenter
|
0x0080
|
在可用空间垂直居中。 |
Qt::AlignBaseline
|
0x0100
|
与基线对齐。 |
You can use only one of the horizontal flags at a time. There is one two-dimensional flag:
常量 | 值 | 描述 |
---|---|---|
Qt::AlignCenter
|
AlignVCenter | AlignHCenter
|
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:
常量 | 值 | 描述 |
---|---|---|
Qt::AlignAbsolute
|
0x0010
|
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
|
AlignLeft
|
Synonym for Qt::AlignLeft. |
Qt::AlignTrailing
|
AlignRight
|
Synonym for Qt::AlignRight. |
Masks:
常量 | 值 |
---|---|
Qt::AlignHorizontal_Mask
|
AlignLeft | AlignRight | AlignHCenter | AlignJustify | AlignAbsolute
|
Qt::AlignVertical_Mask
|
AlignTop | AlignBottom | AlignVCenter | AlignBaseline
|
Conflicting combinations of flags have undefined meanings.
The Alignment type is a typedef for QFlags <AlignmentFlag>. It stores an OR combination of AlignmentFlag values.
Specifies a side of a layout item that can be anchored. This is used by QGraphicsAnchorLayout .
常量 | 值 | 描述 |
---|---|---|
Qt::AnchorLeft
|
0
|

|
3
|
The top side of a layout item. |
Qt::AnchorVerticalCenter
|
4
|
A "virtual" side that is centered between the top and the bottom side of a layout item. |
Qt::AnchorBottom
|
5
|
The bottom side of a layout item. |

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 | 值 | 描述 |
---|---|---|
Qt::AA_DontShowIconsInMenus
|
2
|
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 macOS menubar may not pick up a change in this attribute. Changes in the QAction::iconVisibleInMenu property will always be picked up. |
Qt::AA_DontShowShortcutsInContextMenus
|
28
|
Actions with the Shortcut property won't be shown in any shortcut menus unless specifically set by the QAction::shortcutVisibleInContextMenu property. This value was added in Qt 5.10. |
Qt::AA_NativeWindows
|
3
|
Ensures that widgets have native windows. |
Qt::AA_DontCreateNativeWidgetSiblings
|
4
|
Ensures that siblings of native widgets stay non-native unless specifically set by the Qt::WA_NativeWindow 属性。 |
Qt::AA_PluginApplication
|
5
|
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 AA_DontUseNativeMenuBar 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
|
6
|
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
|
7
|
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. QKeySequence::StandardKey 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 () will be different). |
Qt::AA_Use96Dpi
|
8
|
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
|
11
|
All mouse events that are not accepted by the application will be translated to touch events instead. |
Qt::AA_SynthesizeMouseForUnhandledTouchEvents
|
12
|
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
|
13
|
Make QIcon::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
|
14
|
Make top-level widgets use pure raster surfaces, and do not support non-native GL-based child widgets. |
Qt::AA_UseDesktopOpenGL
|
15
|
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
|
16
|
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
|
17
|
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
|
18
|
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
|
19
|
Indicates whether a palette was explicitly set on the QGuiApplication . This value was added in Qt 5.5. |
Qt::AA_EnableHighDpiScaling
|
20
|
Enables high-DPI scaling in Qt on supported platforms (see also 高 DPI 显示 ). 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
|
21
|
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 QPaintDevice::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
|
22
|
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 methods. See The Style Sheet Syntax - Inheritance for more details. This value was added in Qt 5.7. |
Qt::AA_DontUseNativeDialogs
|
23
|
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
|
24
|
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
|
25
|
Enables compression of certain frequent events. On the X11 windowing system, the default value is true, which means that QEvent::MouseMove , QEvent::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 AA_CompressTabletEvents if you want these to be compressed as well. This value was added in Qt 5.7. |
Qt::AA_CompressTabletEvents
|
29
|
Enables compression of input events from tablet devices. Notice that AA_CompressHighFrequencyEvents 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
|
26
|
When making a context current using QOpenGLContext , do not check that the QObject thread affinity of the QOpenGLContext object is the same thread calling makeCurrent() . This value was added in Qt 5.8. |
Qt::AA_DisableShaderDiskCache
|
27
|
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
|
30
|
Disables the WindowContextHelpButtonHint by default on Qt::Sheet and Qt::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. |
The following values are deprecated or obsolete:
常量 | 值 | 描述 |
---|---|---|
Qt::AA_ImmediateWidgetCreation
|
0
|
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
|
AA_PluginApplication
|
This attribute has been deprecated. Use AA_PluginApplication instead. |
Qt::AA_MSWindowsUseDirect3DByDefault
|
1
|
This value is obsolete and has no effect. |
Qt::AA_X11InitThreads
|
10
|
This value is obsolete and has no effect. |
This enum type is used to specify the current state of the application.
The states are
常量 | 值 | 描述 |
---|---|---|
Qt::ApplicationSuspended
|
0x00000000
|
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
|
0x00000001
|
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
|

常量 | 值 | 描述 |
---|---|---|
Qt::ThresholdAlphaDither
|
0x00000000
|
(default) - No dithering. |

|
A faster, ordered dither. |
Qt::DiffuseAlphaDither
|
0x00000008

Color matching versus dithering preference:
常量 | 值 | 描述 |
---|---|---|

0x00000040
|
Always dither images when converting to smaller color-spaces. |
Qt::AvoidDither
|

(default) - Only dither when down-converting to 1 or 8-bit indexed formats. |
Qt::NoOpaqueDetection
|
0x00000100
|
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
|
0x00000200
|
Don't do any format conversions on the image. Can be useful when converting a QImage to a 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. |

此枚举描述项的特性:
常量 | 值 | 描述 |
---|---|---|
Qt::NoItemFlags
|
0
|
It does not have any properties set. |
Qt::ItemIsSelectable
|
1
|
它可以被选中。 |

|
The user can interact with the item. |
Qt::ItemIsAutoTristate
|
64
|
The item's state depends on the state of its children. This enables automatic management of the state of parent items in QTreeWidget (checked if all children are checked, unchecked if all children are unchecked, or partially checked if only some children are checked). |
Qt::ItemIsTristate
|
ItemIsAutoTristate
|
This enum value is deprecated. Use Qt::ItemIsAutoTristate instead. |
Qt::ItemNeverHasChildren

Note that checkable items need to be given both a suitable set of flags and an initial state, indicating whether the item is checked or not. This is handled automatically for model/view components, but needs to be explicitly set for instances of QListWidgetItem , QTableWidgetItem ,和 QTreeWidgetItem .
Note that it is undefined behavior to reimplement QAbstractItemModel::hasChildren to return true for an index if that index has the Qt::ItemNeverHasChildren flag set.
The ItemFlags type is a typedef for QFlags <ItemFlag>. It stores an OR combination of ItemFlag values.

On UNIX (including Linux, macOS , and iOS), Qt will keep millisecond accuracy for Qt::PreciseTimer. For Qt::CoarseTimer, the interval will be adjusted up to 5% to align the timer with other timers that are expected to fire at or around the same time. The objective is to make most timers wake up at the same time, thereby reducing CPU wakeups and power consumption.
在 Windows,Qt 将为 Qt::PreciseTimer 使用 Windows 的多媒体计时器功能 (若可用),为 Qt::CoarseTimer 和 Qt::VeryCoarseTimer 使用正常 Windows 计时器。
在所有平台,Qt::VeryCoarseTimer 的间隔被圆整到最近完整秒 (如 23500ms 间隔将被圆整到 24000ms, 而 20300ms 将被圆整到 20000ms)。

|
Allows data from drag and drop operations to be dropped onto the widget (see QWidget::setAcceptDrops ()). |
Qt::WA_AlwaysShowToolTips
|
84
|
Enables tooltips for inactive windows. |
Qt::WA_ContentsPropagated
|
3
|
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
|
47
|
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
|
55
|
Makes Qt delete this widget when the widget has accepted the close event (see QWidget::closeEvent ()). |
Qt::WA_Disabled
|
0
|
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
|
103
|
Indicates that the widget is hidden or is not a part of the viewable Desktop. |
Qt::WA_ForceDisabled
|
32
|
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 () 和 QWidget::setDisabled (). |
Qt::WA_ForceUpdatesDisabled
|
59
|
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
|
72
|
This attribute has been deprecated. 使用 QWidget::windowModality 代替。 |
Qt::WA_Hover
|
74

|
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
|
77
|
Set on a toplevel window when the users changes focus with the keyboard (tab, backtab, or shortcut). |
Qt::WA_KeyCompression
|
33
|
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
|
48
|
Indicates that the widget wants QLayout to operate on the entire QWidget::rect (), not only on QWidget::contentsRect (). This is set by the widget's author. |
Qt::WA_LayoutUsesWidgetRect
|
92
|
Ignore the layout item rect from the style when laying out this widget with QLayout . |
Qt::WA_MacNoClickThrough
|
12
|
This value is obsolete and has no effect. |
Qt::WA_MacOpaqueSizeGrip

85
|
Indicates that the native Carbon 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
|
88
|
Indicates that this widget should get a 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 macOS . |
Qt::WA_MacNormalSize
|
89
|
Indicates the widget should have the normal size for widgets in macOS . This attribute is only applicable to macOS . |
Qt::WA_MacSmallSize

11
|
Indicates that the widget is mapped on screen. This is set/cleared by the Qt kernel. |
Qt::WA_MouseNoMask
|
71
|
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
|
2
|
Indicates that the widget has mouse tracking enabled. See QWidget::mouseTracking . |
Qt::WA_Moved
|
43
|
Indicates that the widget has an explicit position. This is set/cleared by QWidget::move () and by QWidget::setGeometry (). |
Qt::WA_MSWindowsUseDirect3D
|
94
|
This value is obsolete and has no effect. |
Qt::WA_NoBackground
|
WA_OpaquePaintEvent
|
此值已过时。使用 WA_OpaquePaintEvent 代替。 |
Qt::WA_NoChildEventsForParent
|
58
|
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
|
39
|
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
|
54
|
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. |

73
|
Prohibits mouse events from being propagated to the widget's parent. This attribute is disabled by default. |
Qt::WA_TransparentForMouseEvents
|
51
|
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
|
9
|
Indicates that the widget has no background, i.e. when the widget receives paint events, the background is not automatically repainted. 注意 : 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
|
4
|
指示 Widget 描绘其所有像素,当它接收描绘事件时。因此,不需要采用 (像更新、重置尺寸、卷动及聚焦改变的) 操作擦除 Widget,在生成描绘事件之前。使用 WA_OpaquePaintEvent 提供小的优化,通过帮助减少在不支持双缓冲的系统上的闪烁,并在描绘之前避免擦除背景必要的计算周期。 注意 :不像 WA_NoSystemBackground,WA_OpaquePaintEvent 努力避免透明窗口背景。此标志由 Widget 作者设置或清零。 |
Qt::WA_OutsideWSRange
|
49
|
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
|
8
|
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_PaintUnclipped
|
52
|
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
|
34
|
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
|
35
|
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
|
76
|
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
|
42
|
Indicates that the widget has an explicit size. This flag is set or cleared by QWidget::resize () 和 QWidget::setGeometry (). |
Qt::WA_RightToLeft
|
56
|
Indicates that the layout direction for the widget is right to left. |
Qt::WA_SetCursor
|
38
|
Indicates that the widget has a cursor of its own. This flag is set or cleared by QWidget::setCursor () 和 QWidget::unsetCursor (). |
Qt::WA_SetFont
|
37
|
Indicates that the widget has a font of its own. This flag is set or cleared by QWidget::setFont (). |
Qt::WA_SetPalette

|
70
|
This attribute has been deprecated. 使用 QWidget::windowModality 代替。 |
Qt::WA_StaticContents
|
5
|
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
|
97
|
Indicates that the widget is styled using a style sheet . WA_StyleSheet 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
|
131
|
Indicates that the widget appearance was modified by a style sheet . WA_StyleSheet will also be set. |
Qt::WA_TabletTracking
|
129
|
Indicates that the widget has tablet tracking enabled. See QWidget::tabletTracking . |
Qt::WA_TranslucentBackground
|
120
|
指示 Widget 应该具有半透明的背景,即:Widget 的任何不透明区域会是半透明的,因为 Widget 将具有 Alpha 通道。设置此标志导致 WA_NoSystemBackground 被设置。在 Windows 小部件还需要 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
|
1
|
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. |

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. This attribute has no effect on non-X11 platforms. 注意 : Qt automatically sets this attribute for the QComboBox pop-up. |
Qt::WA_X11NetWmWindowTypeDND
|
116
|
Adds _NET_WM_WINDOW_TYPE_DND 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 on the feedback widget used during a drag. |
Qt::WA_MacFrameworkScaled
|
117
|
This value is obsolete and has no effect. |
Qt::WA_AcceptTouchEvents
|
121
|
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
|
123
|
Allows touchpad single touch events to be sent to the widget. |
Qt::WA_X11DoNotAcceptFocus
|
126
|
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
|
128
|
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
|
130
|
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 Qt::WA_LayoutOnEntireRect 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. |
This enum is used to describe parts of a window frame. It is returned by QGraphicsWidget::windowFrameSectionAt () to describe what section of the window frame is under the mouse.

This enum specifies the behavior of a modal window. A modal window is one that blocks input to other windows. Note that windows that are children of a modal window are not blocked.
The values are:
常量 | 值 | 描述 |
---|---|---|
Qt::NonModal
|
0
|
The window is not modal and does not block input to other windows. |
Qt::WindowModal
|
1
|
The window is modal to a single window hierarchy and blocks input to its parent window, all grandparent windows, and all siblings of its parent and grandparent windows. |
Qt::ApplicationModal
|
2
|
The window is modal to the application and blocks input to all windows. |

|
窗口未设置状态 (在正常状态)。 |
Qt::WindowMinimized
|
0x00000001
|
The window is minimized (i.e. iconified). |
Qt::WindowMaximized
|
0x00000002
|
The window is maximized with a frame around it. |
Qt::WindowFullScreen
|
0x00000004
|
The window fills the entire screen without any frame around it. |
Qt::WindowActive
|
0x00000008
|
The window is the active window, i.e. it has keyboard focus. |
The WindowStates type is a typedef for QFlags <WindowState>. It stores an OR combination of WindowState values.
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
常量 | 值 | 描述 |
---|---|---|
Qt::Widget
|
0x00000000
|
This is the default type for 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
|
0x00000001
|
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
|
0x00000002 | Window
|
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 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
|
0x00000004 | Window
|
Indicates that the window is a sheet on macOS . Since using a sheet implies window modality, the recommended way is to use QWidget::setWindowModality (),或 QDialog::open (), instead. |
Qt::Drawer
|
Sheet | Dialog
|
Indicates that the widget is a drawer on macOS . |
Qt::Popup
|
0x00000008 | Window
|
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
|
Popup | Dialog
|
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. 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 Qt::WA_MacAlwaysShowToolWindow 属性。 |
Qt::ToolTip
|
Popup | Sheet
|
Indicates that the widget is a tooltip. This is used internally to implement tooltips . |
Qt::SplashScreen
|
ToolTip | Dialog
|
Indicates that the window is a splash screen. This is the default type for QSplashScreen . |
Qt::Desktop
|
0x00000010 | Window
|
Indicates that this widget is the desktop. This is the type for QDesktopWidget. |
Qt::SubWindow
|
0x00000012
|
Indicates that this widget is a sub-window, such as a QMdiSubWindow 小部件。 |
Qt::ForeignWindow
|
0x00000020 | Window
|
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
|
0x00000040 | Window
|
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 | 值 | 描述 |
---|---|---|
Qt::MSWindowsFixedSizeDialogHint
|
0x00000100
|
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 | 值 | 描述 |
---|---|---|
Qt::MSWindowsOwnDC
|
0x00000200
|
Gives the window its own display context on Windows. |
Qt::BypassWindowManagerHint
|
0x00000400
|
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
|
BypassWindowManagerHint
|
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
|
0x00000800
|
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
|
0x40000000
|
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 | 值 | 描述 |
---|---|---|
Qt::CustomizeWindowHint
|
0x02000000
|
Turns off the default window title hints. |
Qt::WindowTitleHint
|
0x00001000
|
Gives the window a title bar. |
Qt::WindowSystemMenuHint
|
0x00002000
|
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
|
0x00004000
|
Adds a minimize button. On some platforms this implies Qt::WindowSystemMenuHint for it to work. |
Qt::WindowMaximizeButtonHint
|
0x00008000
|
Adds a maximize button. On some platforms this implies Qt::WindowSystemMenuHint for it to work. |
Qt::WindowMinMaxButtonsHint
|
WindowMinimizeButtonHint | WindowMaximizeButtonHint
|
Adds a minimize and a maximize button. On some platforms this implies Qt::WindowSystemMenuHint for it to work. |
Qt::WindowCloseButtonHint
|
0x08000000
|
Adds a close button. On some platforms this implies Qt::WindowSystemMenuHint for it to work. |
Qt::WindowContextHelpButtonHint
|
0x00010000
|
Adds a context help button to dialogs. On some platforms this implies Qt::WindowSystemMenuHint for it to work. |
Qt::MacWindowToolBarButtonHint
|
0x10000000
|
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
|
0x80000000
|
On macOS adds a fullscreen button. |
Qt::BypassGraphicsProxyWidget
|
0x20000000
|
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
|
0x00020000
|
Adds a shade button in place of the minimize button if the underlying window manager supports it. |
Qt::WindowStaysOnTopHint
|
0x00040000
|
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
|
0x04000000
|
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: On Windows, this will work only for frameless or full-screen windows.
常量 | 值 | 描述 |
---|---|---|
Qt::WindowTransparentForInput
|
0x00080000
|
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
|
0x00100000
|
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
|
0x00200000
|
Informs the window system that this window should not receive the input focus. |
Qt::MaximizeUsingFullscreenGeometryHint
|
0x00400000
|
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 QScreen::availableGeometry () into account, so that any UI elements in the application that require user interaction are not covered by system UI. |
Qt::WindowType_Mask
|
0x000000ff
|
A mask for extracting the window type part of the window flags. |
The WindowFlags type is a typedef for QFlags <WindowType>. It stores an OR combination of WindowType values.
