[PySide] Application.type doesn't exist in PySide2 anymore

[Alexandru Croitor]

Hi,


There's no direct equivalent of qobject_cast in PySide2 afaik.


Perhaps you can use the qApp macro, something like:


 from PySide2.QtWidgets import QApplication

 from PySide2 import QtCore

 app = QApplication([])

 if isinstance(QtCore.qApp, QApplication):

  ....


or alternatively type(QtCore.qApp).__name__ and then a string compare, which avoids importing.

Or some variation of the above.


Note you might stumble on https://bugreports.qt.io/browse/PYSIDE-585 due to qApp usage.

I am finally getting back to this now.
I can't find qobject_cast anywhere. I can only find the C++ example<http://doc.qt.io/qt-5/qobject.html#qobject_cast> which confuses me a bit though.
Could somebody share an example how to check the application type in PySide2 please?

Cheers,
frank

·         QCoreApplication::Type and QApplication::type() are removed. These Qt 3 legacy application types did not match the application types available in Qt 5. Use qobject_cast instead to dynamically find out the exact application type.

And another PySide2 migration question:
I used to do this to check id an app is run in GUI or command line mode:
if QtWidgets.QApplication.type() == QtWidgets.QApplication.Type.GuiClient:
    ...

However QtWidgets.QApplication.type() doesn't exist in PySdie2 anymore.
What's the best way to achieve the same goal?

Thanks,
frank
