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.

class PySide6.QtQuick.QQuickView(engine, parent)#

PySide6.QtQuick.QQuickView([parent=None])

PySide6.QtQuick.QQuickView(source, renderControl)

PySide6.QtQuick.QQuickView(source[, parent=None])

Parameters:

renderControl – PySide6.QtQuick.QQuickRenderControl
source – 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 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.

Access functions:

property PᅟySide6.QtQuick.QQuickView.status: Status#

The component’s current status .

Access functions:
