Detailed Description#
Warning
This section contains snippets that were automatically translated from C++ to Python and may contain errors.
This is a convenience subclass of QQuickWindow
which will automatically load and display a QML scene when given the URL of the main source file. Alternatively, you can instantiate your own objects using QQmlComponent
and place them in a manually setup QQuickWindow
.
Typical usage:
if __name__ == "__main__": app = QGuiApplication(argc, argv) view = QQuickView() view.setSource(QUrl.fromLocalFile("myqmlfile.qml")) view.show() sys.exit(app.exec())
To receive errors related to loading and executing QML with QQuickView
, you can connect to the statusChanged()
signal and monitor for Error
. The errors are available via errors()
.
QQuickView
also manages sizing of the view and root object. By default, the resizeMode
is SizeViewToRootObject
, which will load the component and resize it to the size of the view. Alternatively the resizeMode
may be set to SizeRootObjectToView
which will resize the view to the size of the root object.

PySide6.QtQuick.QQuickView([parent=None])
PySide6.QtQuick.QQuickView(source, renderControl)
PySide6.QtQuick.QQuickView(source[, parent=None])
- Parameters:
renderControl –

PySide6.QtCore.QUrl
engine –
PySide6.QtQml.QQmlEngine
parent –
PySide6.QtGui.QWindow
Constructs a QQuickView
with the given QML engine
and parent
.
Note: In this case, the QQuickView
does not own the given engine
object; it is the caller’s responsibility to destroy the engine. If the engine
is deleted before the view, status()
will return Error
.
Constructs a QQuickView
with the given parent
. The default value of parent
is 0.
Constructs a QQuickView
with the given QML source
and parent
. The default value of parent
is 0.
Note
Properties can be used directly when from __feature__ import true_property
is used or via accessor functions otherwise.
- property PᅟySide6.QtQuick.QQuickView.resizeMode: ResizeMode#
This property holds whether the view should resize the window contents.
If this property is set to SizeViewToRootObject
(the default), the view resizes to the size of the root item in the QML.
If this property is set to SizeRootObjectToView
, the view will automatically resize the root item to the size of the view.

- property PᅟySide6.QtQuick.QQuickView.source: PySide6.QtCore.QUrl#
This property holds The URL of the source of the QML component..
Ensure that the URL provided is full and correct, in particular, use fromLocalFile()
when loading a file from the local filesystem.
Note that setting a source URL will result in the QML component being instantiated, even if the URL is unchanged from the current value.
- property PᅟySide6.QtQuick.QQuickView.status: Status#
The component’s current status
.

Description
QQuickView.SizeViewToRootObject
The view resizes with the root item in the QML.
QQuickView.SizeRootObjectToView
The view will automatically resize the root item to the size of the view.
- PySide6.QtQuick.QQuickView.Status#
Specifies the loading status of the QQuickView
.

One or more errors has occurred. Call
errors()
to retrieve a list of errors.
- PySide6.QtQuick.QQuickView.engine()#
- Return type:
Returns a pointer to the QQmlEngine
used for instantiating QML Components.
- PySide6.QtQuick.QQuickView.errors()#
- Return type:
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.
- PySide6.QtQuick.QQuickView.initialSize()#
- Return type:
Returns the initial size of the root object.
If resizeMode
is QQuickItem::SizeRootObjectToView the root object will be resized to the size of the view. initialSize contains the size of the root object before it was resized.

- PySide6.QtQuick.QQuickView.rootContext()#
- Return type:
This function returns the root of the context hierarchy. Each QML component is instantiated in a QQmlContext
. QQmlContext
‘s are essential for passing data to QML components. In QML, contexts are arranged hierarchically and this hierarchy is managed by the QQmlEngine
.
- PySide6.QtQuick.QQuickView.rootObject()#
- Return type:
Returns the view’s root item
.
- PySide6.QtQuick.QQuickView.setContent(url, component, item)#
- Parameters:
url –
PySide6.QtCore.QUrl
component –
PySide6.QtQml.QQmlComponent
item –
PySide6.QtCore.QObject
- PySide6.QtQuick.QQuickView.setInitialProperties(initialProperties)#
- Parameters:
initialProperties –
Warning

Sets the initial properties initialProperties
with which the QML component gets initialized after calling setSource()
.
view = { QQuickView() } view.setInitialProperties({"x, 100"}, {"width", 50}) view.setSource(QUrl.fromLocalFile("myqmlfile.qml")) view.show()
Note
You can only use this function to initialize top-level properties.
Note
This function should always be called before setSource
, as it has no effect once the component has become Ready
.

- PySide6.QtQuick.QQuickView.setSource(arg__1)#
- Parameters:
arg__1 –
PySide6.QtCore.QUrl
Sets the source to the url
, loads the QML component and instantiates it.
Ensure that the URL provided is full and correct, in particular, use fromLocalFile()
when loading a file from the local filesystem.
Calling this method multiple times with the same url will result in the QML component being reinstantiated.
