Pyqt Qml Error Console Missing

The title says pretty much everything. Lets say I have this simple application: main.py >>> import sys from PyQt5.QtCore import QUrl from PyQt5.QtWidgets import QApplicati

Solution 1:

If all you want is to see error output on the console, you don't need to do anything, because Qt automatically does that anyway. For example, if I change height to heigth in your example, the following message is printed on stderr:

file:///home/foo/test/main.qml:4:17: Cannot assign to non-existent property "heigth" width: 250; heigth: 175

If you want to raise an exception within your application, you can connect to the statusChanged signal and get the details from the errors method:

    def handleStatusChange(status):
        if status == QQuickView.Error:
            errors = appLabel.errors()
            if errors:
                raise Exception(errors[0].description())

    appLabel = QQuickView()
    appLabel.statusChanged.connect(handleStatusChange)
