PySide.QtDeclarative.QDeclarativeView class provides a widget for displaying a Qt Declarative user interface.
PySide.QtDeclarative.QDeclarativeItem objects can be placed on a standard PySide.QtGui.QGraphicsScene and displayed with PySide.QtGui.QGraphicsView . PySide.QtDeclarative.QDeclarativeView 是 PySide.QtGui.QGraphicsView subclass provided as a convenience for displaying QML files, and connecting between QML and C++ Qt objects.
PySide.QtDeclarative.QDeclarativeView provides:
Typical usage:
QDeclarativeView *view = new QDeclarativeView;
view->setSource(QUrl::fromLocalFile("myqmlfile.qml"));
view->show();
Since PySide.QtDeclarative.QDeclarativeView 是 PySide.QtGui.QWidget -based class, it can be used to display QML interfaces within PySide.QtGui.QWidget -based GUI applications that do not use the Graphics View framework.
To receive errors related to loading and executing QML with PySide.QtDeclarative.QDeclarativeView , you can connect to the PySide.QtDeclarative.QDeclarativeView.statusChanged() signal and monitor for QDeclarativeView.Error . The errors are available via QDeclarativeView.errors() .
If you're using your own PySide.QtGui.QGraphicsScene -based scene with PySide.QtDeclarative.QDeclarativeView , remember to enable scene's sticky focus mode and to set itemIndexMethod to QGraphicsScene.NoIndex .

| 参数： |
|
|---|
构造 PySide.QtDeclarative.QDeclarativeView with the given parent .
构造 PySide.QtDeclarative.QDeclarativeView with the given QML source and parent .
This enum specifies how to resize the view.
| 常量 | 描述 |
|---|---|
| QDeclarativeView.SizeViewToRootObject | The view resizes with the root item in the QML. |
| QDeclarativeView.SizeRootObjectToView | The view will automatically resize the root item to the size of the view. |
Specifies the loading status of the PySide.QtDeclarative.QDeclarativeView .
| 常量 | 描述 |
|---|---|
| QDeclarativeView.Null | This PySide.QtDeclarative.QDeclarativeView has no source set. |
| QDeclarativeView.Ready | This PySide.QtDeclarative.QDeclarativeView has loaded and created the QML component. |
| QDeclarativeView.Loading | This PySide.QtDeclarative.QDeclarativeView is loading network data. |
| QDeclarativeView.Error | One or more errors has occurred. Call PySide.QtDeclarative.QDeclarativeView.errors() to retrieve a list of errors. |
| 返回类型： | PySide.QtDeclarative.QDeclarativeEngine |
|---|
返回指针指向 PySide.QtDeclarative.QDeclarativeEngine used for instantiating QML Components.
| 返回类型： |
|---|
Return the list of errors that occurred during the last compile or create operation. When the status is not Error, an empty list is returned.
| 返回类型： | PySide.QtCore.QSize |
|---|
Returns the initial size of the root object
| 返回类型： | PySide.QtDeclarative.QDeclarativeView.ResizeMode |
|---|
This property holds whether the view should resize the canvas contents.
If this property is set to SizeViewToRootObject (the default), the view resizes with the root item in the QML.
If this property is set to SizeRootObjectToView , the view will automatically resize the root item.
Regardless of this property, the sizeHint of the view is the initial size of the root item. Note though that since QML may load dynamically, that size may change.
| 返回类型： | PySide.QtDeclarative.QDeclarativeContext |
|---|
This function returns the root of the context hierarchy. Each QML component is instantiated in a PySide.QtDeclarative.QDeclarativeContext . PySide.QtDeclarative.QDeclarativeContext ‘s are essential for passing data to QML components. In QML, contexts are arranged hierarchically and this hierarchy is managed by the PySide.QtDeclarative.QDeclarativeEngine .
| 返回类型： | PySide.QtGui.QGraphicsObject |
|---|
Returns the view's root item .
| 参数： | size – PySide.QtCore.QSize |
|---|
| 参数： | arg__1 – PySide.QtDeclarative.QDeclarativeView.ResizeMode |
|---|
This property holds whether the view should resize the canvas contents.
If this property is set to SizeViewToRootObject (the default), the view resizes with the root item in the QML.
If this property is set to SizeRootObjectToView , the view will automatically resize the root item.
Regardless of this property, the sizeHint of the view is the initial size of the root item. Note though that since QML may load dynamically, that size may change.
| 参数： | obj – PySide.QtCore.QObject |
|---|
| 参数： | arg__1 – PySide.QtCore.QUrl |
|---|
This property holds The URL of the source of the QML component..
Changing this property causes the QML component to be reloaded.
Ensure that the URL provided is full and correct, in particular, use QUrl.fromLocalFile() when loading a file from the local filesystem.
