QFileDialog Use native dialog despite of Q_OBJECT

[QtAndMore]

Hello together,

I have a problem with QFileDialog.
For some reasons, I don't want to use the Qt user dialog anymore. I want to use the native (Windows) dialog.
The documentation says, that the native dialog is default:

In my case I don't call the option DontUseNativeDialog, but I use the Q_OBJECT macro in the class of FileOpenSaveDialog.

I treid to set the option DontUseNativeDialog to false, but it did not help.

Where is my mistake?!
How is it possible to use native dialog when using Q_OBJECT?

Thank you in advance!

Simply don't subclass fro QFileDialog - from what you're showing it's not needed.

Sadly it is needed, or am I wrong?

I don't see where you call a custom FileOpenSaveDialog function here.
And btw: toAscii() is absolutely wrong
