I am working on a desktop environment and I want my QML window as my main desktop window. I am integrating QML with PyQt5.
here is my code

context.setContextProperty("main", engine)
engine.load('/home/newtron/Muscovy/main.qml')
window = QMainWindow()

win.show()
window.setAttribute(Qt.WA_X11NetWmWindowTypeDesktop, True)

I tried adding window.setAttribute(Qt.WA_X11NetWmWindowTypeDesktop, True) in code but it doesn't work. Also I tried adding Qt.Desktop flag also this doesn't work. At the first time, it gave me error AttributeError: 'QQuickWindow' object has no attribute 'setAttribute'. In second attempt the script ran successfully but window didn't open. I thought it may be because another desktop window is running. So I loggend into an another console with my user name, created a bash file to run window manager and dektop window, then start it by startx /home/newtron/myscript. It opened a blank window. There wasn't even mouse(may be a failure).
can anybody help me?
thanks.
回答1:
Qt::WA_X11NetWmWindowTypeDesktop is a Qt::WidgetAttribute so it only makes sense for the QWidget and it seems that the OP understands it because in its attempt it uses a QMainWindow but the problem is that the QMainWindow does not show the QML so that is not the solution.
The idea is to have a QWidget where the QML is so in this case there are 2 possible solutions:
Set
visible: falsein ApplicationWindow and use QWidget::createWindowContainer():import os import sys from PyQt5.QtCore import Qt, QUrl from PyQt5.QtWidgets import QApplication, QWidget from PyQt5.QtQml import QQmlApplicationEngine DIR_PATH = os.path.dirname(os.path.realpath(__file__)) if __name__ == "__main__": myApp = QApplication(sys.argv) file = os.path.join(DIR_PATH, "main.qml") url = QUrl.fromLocalFile(file) engine = QQmlApplicationEngine() context = engine.rootContext() context.setContextProperty("main", engine) engine.load(url) if not engine.rootObjects(): sys.exit(-1) widget = QWidget.createWindowContainer(engine.rootObjects()[0]) widget.setAttribute(Qt.WA_X11NetWmWindowTypeDesktop, True) widget.showFullScreen() sys.exit(myApp.exec_())main.qml
