cannot access QAxWidget custom event/methods with PyQt6/PySide6

kwiechen

Hi,

I am using a .NET control exposed via COM Interop with a custom event TextModified() and a custom method getText()

The following code is working without problems with PyQt5 but I cannot access custom events or methods of this control using PyQt6/PySide6. The control is loaded and displayed correctly.

class MainForm(QMainWindow):
def init(self, parent=None):
super(MainForm, self).init(parent)

    self.widget = QWidget()
    self.layout = QVBoxLayout()
    self.axWidget = QAxWidget("my ID")
    self.axWidget.TextModified.connect(self.notify)
    self.layout.addWidget(self.axWidget)
    self.widget.setLayout(self.layout)
    self.setCentralWidget(self.widget)

def notify(self):
    print(self.axWidget.getText())

If you don't get an answer here and it works under PyQt5 but not PyQt6 you could ask the PyQt folks. I don't know whether this is a Py... issue or an underlying Qt6 one.

I have tested my custom ActiveX using Qt6/C++ without problems. Using Python the QAx.Widget.generateDocumentation() is correct. I think that PyQt5 is autmatically defining signals and methods but PySide6/PyQt6 not. A solution is to subclass QAxWidget defining the ActiveX events/signals explicitly and calling the methods via dynamicCall()

Hi,

It sounds like a regression then since it used to work.

Did you already check the bug report system ?

If there's nothing there, then please consider opening a new report with your findings.
