## Detailed Description
该QGraphicsWidget类是在所有部件项目的基类[QGraphicsScene](qgraphicsscene.html)。
QGraphicsWidget是一个扩展的基地项目,超过提供额外的功能[QGraphicsItem](qgraphicsitem.html)。它类似于[QWidget](qwidget.html)在很多方面:
* Provides a [palette](qgraphicswidget.html#palette-prop), a [font](qgraphicswidget.html#font-prop) and a [style](qgraphicswidget.html#style)().
* Has a defined [geometry](qgraphicslayoutitem.html#geometry)().
* Supports layouts with [setLayout](qgraphicswidget.html#layout-prop)() and [layout](qgraphicswidget.html#layout-prop)().
* Supports shortcuts and actions with [grabShortcut](qgraphicswidget.html#grabShortcut)() and [insertAction](qgraphicswidget.html#insertAction)()
不像[QGraphicsItem](qgraphicsitem.html), QGraphicsWidget不是一个抽象类,你可以创建一个QGraphicsWidget的实例,而无需继承它。这种方法对小部件,只有服务于构建子控件到布局的目的是有用的。
QGraphicsWidget如果您需要先进的输入焦点的处理,例如,标籤对焦和激活,或布局被用来作为自己的自定义项目的基础项目。
由于QGraphicsWidget酷似[QWidget](qwidget.html)并具有类似的API ,它更容易端口插件从[QWidget](qwidget.html)到QGraphicsWidget ,而不是[QGraphicsItem](qgraphicsitem.html)。
**Note:** [QWidget](qwidget.html)基于窗口小部件可以被直接嵌入到一个[QGraphicsScene](qgraphicsscene.html) using [QGraphicsProxyWidget](qgraphicsproxywidget.html)。
QGraphicsWidget之间明显的差异[QWidget](qwidget.html)分别是:
| QGraphicsWidget | [QWidget](qwidget.html) |
| --- | --- |
| Coordinates and geometry are defined with qreals (doubles or floats, depending on the platform). | [QWidget](qwidget.html) uses integer geometry ([QPoint](qpoint.html), [QRect](qrect.html)). |
| The widget is already visible by default; you do not have to call [show](qgraphicsitem.html#show)() to display the widget. | [QWidget](qwidget.html) is hidden by default until you call [show](qgraphicsitem.html#show)(). |
| A subset of widget attributes are supported. | All widget attributes are supported. |
| A top-level item's style defaults to QGraphicsScene.style | A top-level widget's style defaults to QApplication.style |
| Graphics View provides a custom drag and drop framework, different from [QWidget](qwidget.html). | Standard drag and drop framework. |
| Widget items do not support modality. | Full modality support. |
QGraphicsWidget支持Qt的窗口部件的属性的一个子集, ([Qt.WidgetAttribute](qt.html#WidgetAttribute-enum))所示,在下表中。本表中未列出的任何属性是不支持的,或以其他方式使用。
| Widget Attribute | Usage |
| --- | --- |
| [Qt.WA_SetLayoutDirection](qt.html#WidgetAttribute-enum) | Set by [setLayoutDirection](qgraphicswidget.html#layoutDirection-prop)(), cleared by [unsetLayoutDirection](qgraphicswidget.html#layoutDirection-prop)(). You can test this attribute to check if the widget has been explicitly assigned a [layoutDirection](qgraphicswidget.html#layoutDirection-prop). If the attribute is not set, the [layoutDirection()](qgraphicswidget.html#layoutDirection-prop) is inherited. |
| [Qt.WA_RightToLeft](qt.html#WidgetAttribute-enum) | Toggled by [setLayoutDirection](qgraphicswidget.html#layoutDirection-prop)(). Inherited from the parent/scene. If set, the widget's layout will order horizontally arranged widgets from right to left. |
| [Qt.WA_SetStyle](qt.html#WidgetAttribute-enum) | Set and cleared by [setStyle](qgraphicswidget.html#setStyle)(). If this attribute is set, the widget has been explicitly assigned a style. If it is unset, the widget will use the scene's or the application's style. |
| [Qt.WA_Resized](qt.html#WidgetAttribute-enum) | Set by [setGeometry](qgraphicswidget.html#geometry-prop)() and [resize](qgraphicswidget.html#size-prop)(). |
| [Qt.WA_SetPalette](qt.html#WidgetAttribute-enum) | Set by [setPalette](qgraphicswidget.html#palette-prop)(). |
| [Qt.WA_SetFont](qt.html#WidgetAttribute-enum) | Set by [setFont](qgraphicswidget.html#font-prop)(). |
| [Qt.WA_WindowPropagation](qt.html#WidgetAttribute-enum) | Enables propagation to window widgets. |
虽然QGraphicsWidget从两个继承[QObject](qobject.html)和[QGraphicsItem](qgraphicsitem.html),你应该使用所提供的功能[QGraphicsItem](qgraphicsitem.html),_not_ [QObject](qobject.html),管理父和子项之间的关系。这些功能控制项目的堆叠顺序以及它们的所有权。
**Note:**该[QObject.parent](qobject.html#parent)( )应该总是返回0 QGraphicsWidgets ,但这项政策没有严格的定义。
* * *
## Method Documentation
```
QGraphicsWidget.__init__ (self, QGraphicsItem parent = None, Qt.WindowFlags flags = 0)
```
该_parent_的说法,如果不是没有,原因_self_通过Qt的,而不是PyQt的拥有。
构造一个[QGraphicsWidget](qgraphicswidget.html)实例。可选的_parent_参数被传递给[QGraphicsItem](qgraphicsitem.html)的构造。可选的_wFlags_参数指定了小部件的窗口标志(例如,小部件是否应该是一个窗口,一个工具,一个弹出式等) 。
```
list-of-QAction QGraphicsWidget.actions (self)
```
返回这个窗口部件的动作(可能为空)列表。
此功能被引入Qt的4.5 。
**See also** [insertAction](qgraphicswidget.html#insertAction)( )[removeAction](qgraphicswidget.html#removeAction)( )[QWidget.actions](qwidget.html#actions)( )[QAction.associatedWidgets](qaction.html#associatedWidgets)()和[QAction.associatedGraphicsWidgets](qaction.html#associatedGraphicsWidgets)( ) 。
```
QGraphicsWidget.addAction (self, QAction action)
```
追加行动_action_以行动这个小工具的列表。
所有QGraphicsWidgets具有列表[QAction](qaction.html)秒,但是它们可以被以图形方式在许多不同的方式来表示。在默认情况下使用的[QAction](qaction.html)列表(所返回[actions](qgraphicswidget.html#actions)())是创建一个上下文[QMenu](qmenu.html)。
A [QGraphicsWidget](qgraphicswidget.html)应该只有每个动作中的一个,并将其添加已经有一个操作不会导致相同的动作是在插件的两倍。
此功能被引入Qt的4.5 。
**See also** [removeAction](qgraphicswidget.html#removeAction)( )[insertAction](qgraphicswidget.html#insertAction)( )[actions](qgraphicswidget.html#actions)()和[QWidget.addAction](qwidget.html#addAction)( ) 。
```
QGraphicsWidget.addActions (self, list-of-QAction actions)
```
追加行动_actions_以行动这个小工具的列表。
此功能被引入Qt的4.5 。
**See also** [removeAction](qgraphicswidget.html#removeAction)( )[QMenu](qmenu.html),[addAction](qgraphicswidget.html#addAction)()和[QWidget.addActions](qwidget.html#addActions)( ) 。
```
QGraphicsWidget.adjustSize (self)
```
调整小部件的大小达到有效的首选大小的提示。
这个函数被调用时隐式的项目显示的第一次。
**See also** [effectiveSizeHint](qgraphicslayoutitem.html#effectiveSizeHint)()和[Qt.MinimumSize](qt.html#SizeHint-enum)。
```
bool QGraphicsWidget.autoFillBackground (self)
```
```
QRectF QGraphicsWidget.boundingRect (self)
```
[](qrectf.html)
[从重新实现](qrectf.html)[QGraphicsItem.boundingRect](qgraphicsitem.html#boundingRect)( ) 。
```
QGraphicsWidget.changeEvent (self, QEvent event)
```
此事件处理程序可以重新实现来处理状态的变化。
在这种情况下被改变的状态可以通过检索_event_。
更改事件包括:[QEvent.ActivationChange](qevent.html#Type-enum),[QEvent.EnabledChange](qevent.html#Type-enum),[QEvent.FontChange](qevent.html#Type-enum),[QEvent.StyleChange](qevent.html#Type-enum),[QEvent.PaletteChange](qevent.html#Type-enum),[QEvent.ParentChange](qevent.html#Type-enum),[QEvent.LayoutDirectionChange](qevent.html#Type-enum)和[QEvent.ContentsRectChange](qevent.html#Type-enum)。
```
bool QGraphicsWidget.close (self)
```
这种方法也是一个Qt槽与C + +的签名`bool close()`。
调用这个函数来关闭该窗口小部件。
返回True如果部件被关闭,否则返回False 。此插槽会先发送一个[QCloseEvent](qcloseevent.html)到窗口小部件,它可以或不可以接受的事件。如果事件被忽略,没有任何反应。如果事件被接受,它会[hide](qgraphicsitem.html#hide)()的部件。
如果部件有[Qt.WA_DeleteOnClose](qt.html#WidgetAttribute-enum)属性设置将被删除。
```
QGraphicsWidget.closeEvent (self, QCloseEvent event)
```
此事件处理程序,对于_event_,可重新实现在子类中接收部件关闭事件。默认实现接受的事件。
**See also** [close](qgraphicswidget.html#close)()和[QCloseEvent](qcloseevent.html)。
```
bool QGraphicsWidget.event (self, QEvent event)
```
从重新实现[QObject.event](qobject.html#event)( ) 。
处理_event_。[QGraphicsWidget](qgraphicswidget.html)处理以下事项:
| Polish | Delivered to the widget some time after it has been shown. |
| GraphicsSceneMove | Delivered to the widget after its local position has changed. |
| GraphicsSceneResize | Delivered to the widget after its size has changed. |
| Show | Delivered to the widget before it has been shown. |
| Hide | Delivered to the widget after it has been hidden. |
| PaletteChange | Delivered to the widget after its palette has changed. |
| FontChange | Delivered to the widget after its font has changed. |
| EnabledChange | Delivered to the widget after its enabled state has changed. |
| StyleChange | Delivered to the widget after its style has changed. |
| LayoutDirectionChange | Delivered to the widget after its layout direction has changed. |
| ContentsRectChange | Delivered to the widget after its contents margins/ contents rect has changed. |
```
QGraphicsWidget.focusInEvent (self, QFocusEvent event)
```
从重新实现[QGraphicsItem.focusInEvent](qgraphicsitem.html#focusInEvent)( ) 。
```
bool QGraphicsWidget.focusNextPrevChild (self, bool next)
```
发现一个新的widget ,让键盘焦点,以适合Tab和Shift + Tab键,如果能找到一个新的widget返回True,否则返回False 。如果_next_诚然,这个函数向前搜索,如果_next_是假的,它向后搜索。
有时候,你会希望重新实现这个功能,为您的小工具,其subwidgets提供特别注重处理。例如,一个Web浏览器可能会重新实现它移动到其当前活动链接向前或向后,并调用基实现,只有当它到达页面上的最后一个或第一个链接。
子控件调用focusNextPrevChild ( )对它们的父窗口部件,但只有包含的子控件的窗口决定重定向到哪里焦点。通过重新实现这个函数的对象时,你获得控制焦点遍历所有子控件。
**See also** [focusPolicy](qgraphicswidget.html#focusPolicy-prop)( ) 。
```
QGraphicsWidget.focusOutEvent (self, QFocusEvent event)
```
从重新实现[QGraphicsItem.focusOutEvent](qgraphicsitem.html#focusOutEvent)( ) 。
```
Qt.FocusPolicy QGraphicsWidget.focusPolicy (self)
```
[](qt.html#FocusPolicy-enum)
```
QGraphicsWidget QGraphicsWidget.focusWidget (self)
```
[
如果这个小工具的这个小工具,一个孩子或后代目前拥有输入焦点时,这个函数会返回一个指向窗口小部件。如果没有后代部件有输入焦点,则返回0 。

[**See also**](qgraphicswidget.html) [QGraphicsItem.focusItem](qgraphicsitem.html#focusItem)()和[QWidget.focusWidget](qwidget.html#focusWidget)( ) 。
```
QFont QGraphicsWidget.font (self)
```
[
```
(float left, float top, float right, float bottom) QGraphicsWidget.getContentsMargins (self)
```
](qfont.html)
[从重新实现](qfont.html)[QGraphicsLayoutItem.getContentsMargins](qgraphicslayoutitem.html#getContentsMargins)( ) 。
获取控件的内容利润率。页边距都存储在_left_,_top_,_right_和_bottom_,作为指针指向qreals 。每个参数可以是_omitted_通过传递0 。
**See also** [setContentsMargins](qgraphicswidget.html#setContentsMargins)( ) 。
```
(float left, float top, float right, float bottom) QGraphicsWidget.getWindowFrameMargins (self)
```
获取控件的窗口框架的利润。页边距都存储在_left_,_top_,_right_和_bottom_作为指针指向qreals 。每个参数可以是_omitted_通过传递0 。
**See also** [setWindowFrameMargins](qgraphicswidget.html#setWindowFrameMargins)()和[windowFrameRect](qgraphicswidget.html#windowFrameRect)( ) 。
```
QGraphicsWidget.grabKeyboardEvent (self, QEvent event)
```
此事件处理程序,对于_event_,可以在子类来接收通知被重新实现[QEvent.GrabKeyboard](qevent.html#Type-enum)事件。
**See also** [grabKeyboard](qgraphicsitem.html#grabKeyboard)()和[grabMouse](qgraphicsitem.html#grabMouse)( ) 。
```
QGraphicsWidget.grabMouseEvent (self, QEvent event)
```
此事件处理程序,对于_event_,可以在子类来接收通知被重新实现[QEvent.GrabMouse](qevent.html#Type-enum)事件。
**See also** [grabMouse](qgraphicsitem.html#grabMouse)()和[grabKeyboard](qgraphicsitem.html#grabKeyboard)( ) 。
```
int QGraphicsWidget.grabShortcut (self, QKeySequence sequence, Qt.ShortcutContext context = Qt.WindowShortcut)
```
增加了一个快捷方式到Qt的快捷键系统,手表对于给定的键_sequence_在给定的_context_。如果_context_ is [Qt.ApplicationShortcut](qt.html#ShortcutContext-enum),快捷适用于应用程序作为一个整体。否则,要么是本地的这个小工具,[Qt.WidgetShortcut](qt.html#ShortcutContext-enum),或者窗口本身,[Qt.WindowShortcut](qt.html#ShortcutContext-enum)。对于小部件不属于窗口的一部分(即顶层widget和他们的孩子) ,[Qt.WindowShortcut](qt.html#ShortcutContext-enum)快捷方式适用于现场。
如果相同的密钥_sequence_已经抓住了由几个部件,当键_sequence_发生[QEvent.Shortcut](qevent.html#Type-enum)事件被发送到所有的,它适用于非确定性的顺序小部件,而是用``暧昧''标志设置为True 。
**Warning:**你不应该通常需要使用此功能,而是创建[QAction](qaction.html)s的您需要的快捷键顺序(如果你也想等效的菜单选项和工具栏按钮) ,或创建[QShortcut](qshortcut.html)■如果您只需要按键顺序。两[QAction](qaction.html)和[QShortcut](qshortcut.html)处理所有的事件过滤的你,提供当用户触发键序列触发信号,所以更容易比这个低层次的功能使用。
此功能被引入Qt的4.5 。
**See also** [releaseShortcut](qgraphicswidget.html#releaseShortcut)( )[setShortcutEnabled](qgraphicswidget.html#setShortcutEnabled)()和[QWidget.grabShortcut](qwidget.html#grabShortcut)( ) 。
```
QGraphicsWidget.hideEvent (self, QHideEvent event)
```
此事件处理程序,对于[Hide](qevent.html#Type-enum)事件被交付的部件已被隐藏之后,例如,其setVisible (假)被称为小部件或其祖先之一,当小部件曾表明。
您可以重新实现此事件处理程序来检测,当你的小部件被隐藏。调用[QEvent.accept](qevent.html#accept)()或[QEvent.ignore](qevent.html#ignore)( )上_event_没有任何影响。
**See also** [showEvent](qgraphicswidget.html#showEvent)( )[QWidget.hideEvent](qwidget.html#hideEvent)()和[ItemVisibleChange](qgraphicsitem.html#GraphicsItemChange-enum)。
```
QGraphicsWidget.hoverLeaveEvent (self, QGraphicsSceneHoverEvent event)
```
从重新实现[QGraphicsItem.hoverLeaveEvent](qgraphicsitem.html#hoverLeaveEvent)( ) 。
```
QGraphicsWidget.hoverMoveEvent (self, QGraphicsSceneHoverEvent event)
```
从重新实现[QGraphicsItem.hoverMoveEvent](qgraphicsitem.html#hoverMoveEvent)( ) 。
```
QGraphicsWidget.initStyleOption (self, QStyleOption option)
```
填充这个小工具基于其当前状态的样式选项对象,并存储在输出_option_。默认实现填充_option_具有以下属性。
| Style Option Property | Value |
| --- | --- |
| state & [QStyle.State_Enabled](qstyle.html#StateFlag-enum) | Corresponds to [QGraphicsItem.isEnabled](qgraphicsitem.html#isEnabled)(). |
| state & [QStyle.State_HasFocus](qstyle.html#StateFlag-enum) | Corresponds to [QGraphicsItem.hasFocus](qgraphicsitem.html#hasFocus)(). |
| state & [QStyle.State_MouseOver](qstyle.html#StateFlag-enum) | Corresponds to [QGraphicsItem.isUnderMouse](qgraphicsitem.html#isUnderMouse)(). |
| direction | Corresponds to [QGraphicsWidget.layoutDirection](qgraphicswidget.html#layoutDirection-prop)(). |
| rect | Corresponds to [QGraphicsWidget.rect](qgraphicswidget.html#rect)().toRect(). |
| palette | Corresponds to [QGraphicsWidget.palette](qgraphicswidget.html#palette-prop)(). |
| fontMetrics | Corresponds to [QFontMetrics](qfontmetrics.html)([QGraphicsWidget.font](qgraphicswidget.html#font-prop)()). |
的子类[QGraphicsWidget](qgraphicswidget.html)应该调用基实现,然后测试的类型_option_使用qstyleoption_cast \u003c\u003e()或试验[QStyleOption.Type](qstyleoption.html#StyleOptionType-enum)之前存储部件特定的选项。
例如:
```
void MyGroupBoxWidget.initStyleOption([QStyleOption](qstyleoption.html) *option) const
{
[QGraphicsWidget](qgraphicswidget.html).initStyleOption(option);
if ([QStyleOptionGroupBox](qstyleoptiongroupbox.html) *box = qstyleoption_cast<[QStyleOptionGroupBox](qstyleoptiongroupbox.html) *>(option)) {
// Add group box specific state.
box->flat = isFlat();
...
}
}
```
**See also** [QStyleOption.initFrom](qstyleoption.html#initFrom)( ) 。
```
QGraphicsWidget.insertAction (self, QAction before, QAction action)
```
插入动作_action_以行动,在行动之前,这个小工具的列表_before_。其附加的行动,如果_before_是0或_before_是不是这个小工具的有效行动。
A [QGraphicsWidget](qgraphicswidget.html)应该只有每个动作之一。
此功能被引入Qt的4.5 。
**See also** [removeAction](qgraphicswidget.html#removeAction)( )[addAction](qgraphicswidget.html#addAction)( )[QMenu](qmenu.html),[actions](qgraphicswidget.html#actions)()和[QWidget.insertActions](qwidget.html#insertActions)( ) 。
```
QGraphicsWidget.insertActions (self, QAction before, list-of-QAction actions)
```
插入动作_actions_以行动,在行动之前,这个小工具的列表_before_。其附加的行动,如果_before_是0或_before_是不是这个小工具的有效行动。
A [QGraphicsWidget](qgraphicswidget.html)最多可以有各一个动作。
此功能被引入Qt的4.5 。
**See also** [removeAction](qgraphicswidget.html#removeAction)( )[QMenu](qmenu.html),[insertAction](qgraphicswidget.html#insertAction)()和[QWidget.insertActions](qwidget.html#insertActions)( ) 。
```
bool QGraphicsWidget.isActiveWindow (self)
```
返回True如果这个窗口部件的窗口是活动窗口,或者如果控件没有窗口,但在活跃现场(即,一个场景,当前具有焦点) 。
活动窗口是不是包含当前具有输入焦点的子控件的窗口,或者说本身有输入焦点。
**See also** [QGraphicsScene.activeWindow](qgraphicsscene.html#activeWindow)( )[QGraphicsScene.setActiveWindow](qgraphicsscene.html#setActiveWindow)()和[isActive](qgraphicsitem.html#isActive)( ) 。
```
QVariant QGraphicsWidget.itemChange (self, QGraphicsItem.GraphicsItemChange change, QVariant value)
```
从重新实现[QGraphicsItem.itemChange](qgraphicsitem.html#itemChange)( ) 。
[QGraphicsWidget](qgraphicswidget.html)使用此函数的基实现追赶,并提供相关的项状态变化的事件。因为这一点,这是很重要的,子类调用基实现。
_change_指定变化的类型,并_value_为新的值。
例如,[QGraphicsWidget](qgraphicswidget.html) uses [ItemVisibleChange](qgraphicsitem.html#GraphicsItemChange-enum)交付[Show](qevent.html#Type-enum)和[Hide](qevent.html#Type-enum)事件,[ItemPositionHasChanged](qgraphicsitem.html#GraphicsItemChange-enum)交付[Move](qevent.html#Type-enum)事件,以及[ItemParentChange](qgraphicsitem.html#GraphicsItemChange-enum)既提供[ParentChange](qevent.html#Type-enum)事件,以及用于管理的重点链。
[QGraphicsWidget](qgraphicswidget.html)使[ItemSendsGeometryChanges](qgraphicsitem.html#GraphicsItemFlag-enum)标志在默认情况下,以追踪位置的变化。

](qt.html#LayoutDirection-enum)
[此事件处理程序,对于](qt.html#LayoutDirection-enum)[GraphicsSceneMove](qevent.html#Type-enum)事件,交付后的小部件移动时(例如,它的局部位置发生了变化) 。
当项目在本地移动此事件只交付。调用[setTransform](qgraphicsitem.html#setTransform)()或移动的任何项的祖先不影响产品的本地位置。
您可以重新实现此事件处理程序来检测你的部件已经移动了。调用[QEvent.accept](qevent.html#accept)()或[QEvent.ignore](qevent.html#ignore)( )上_event_没有任何影响。
**See also** [ItemPositionChange](qgraphicsitem.html#GraphicsItemChange-enum)和[ItemPositionHasChanged](qgraphicsitem.html#GraphicsItemChange-enum)。

```
从重新实现[QGraphicsItem.paint](qgraphicsitem.html#paint)( ) 。
```
QGraphicsWidget.paintWindowFrame (self, QPainter painter, QStyleOptionGraphicsItem option, QWidget widget = None)
```
这个虚函数被调用[QGraphicsScene](qgraphicsscene.html)绘制使用Windows的窗口框架_painter_,_option_和_widget_在局部坐标。该基地实现使用目前的风格来渲染框架和标题栏。
您可以在子类中重新实现这个功能[QGraphicsWidget](qgraphicswidget.html)提供widget的窗口框架的自定义呈现。
**See also** [QGraphicsItem.paint](qgraphicsitem.html#paint)( ) 。

```
QGraphicsWidget.releaseShortcut (self, int id)
```
删除快捷方式与给定_id_从Qt的快捷键系统。该部件将不再接收[QEvent.Shortcut](qevent.html#Type-enum)事件的快捷方式的按键顺序(除非它使用相同的密钥序列的其他快捷方式) 。
**Warning:**你不应该通常需要使用此功能,因为Qt的快捷键系统自动删除快捷方式时,他们的父窗口部件被销毁。最好是使用[QAction](qaction.html) or [QShortcut](qshortcut.html)处理快捷方式,因为它们更容易比这低级别的功能来使用。还请注意,这是一个昂贵的操作。
此功能被引入Qt的4.5 。
**See also** [grabShortcut](qgraphicswidget.html#grabShortcut)( )[setShortcutEnabled](qgraphicswidget.html#setShortcutEnabled)()和[QWidget.releaseShortcut](qwidget.html#releaseShortcut)( ) 。

**See also** [QGraphicsItem.sceneEvent](qgraphicsitem.html#sceneEvent)( ) 。
```
QGraphicsWidget.setAttribute (self, Qt.WidgetAttribute attribute, bool on = True)
```
If _on_诚然,这个功能可以让_attribute_否则_attribute_被禁用。
请参阅类文档[QGraphicsWidget](qgraphicswidget.html)对于其中的完整列表属性的支持,他们是干什么用的。

```
QGraphicsWidget.setShortcutEnabled (self, int id, bool enabled = True)
```
If _enabled_诚然,使用快捷给定的_id_被启用,否则快捷方式被禁用。
**Warning:**你不应该通常需要使用此功能,因为Qt的快捷键系统启用/禁用自动快捷方式小部件变为隐藏/可见和获得或失去焦点。最好是使用[QAction](qaction.html) or [QShortcut](qshortcut.html)处理快捷方式,因为它们更容易比这低级别的功能来使用。
此功能被引入Qt的4.5 。

QGraphicsWidget.setTabOrder (QGraphicsWidget first, QGraphicsWidget second)
```
移动_second_围绕焦点窗口小部件的环部件,以便从键盘焦点移动_first_窗口小部件的_second_当按下Tab键时控件。
需要注意的是,因为的Tab键顺序_second_窗口小部件被改变,你应该订购链是这样的:
```
setTabOrder(a, b); // a to b
setTabOrder(b, c); // a to b to c
setTabOrder(c, d); // a to b to c to d
```
_not_像这样:
```
// WRONG
setTabOrder(c, d); // c to d
setTabOrder(a, b); // a to b AND c to d
setTabOrder(b, c); // a to b to c, but not c to d
```
If _first_是0 ,这表明_second_应该是要现场增益选项卡焦点(即用户点击标籤,让焦点传递到场景)来接收输入焦点的第一个部件。如果_second_是0 ,这表明_first_应该是第一个部件获得焦点,如果在现场获得了BACKTAB焦点。
默认情况下, Tab键顺序的定义是隐式使用窗口小部件创建的顺序。
