QFileDialog Question

[ToddAtWSU]

Okay, so this is starting to make some sense. We are forced to use Gnome and when I run some applications, I get an error: GTK-Message: GTKDialog mapped without a transient parent. This is discouraged.

So maybe it is trying to use the GTKDialog for the QFileDialog, and I get this error as it doesn't know how to use a QMainWindow for its parent. And then maybe if I don't use the native dialog like you suggest, it will work. I wasn't certain if I was using the native dialog because the documentation wasn't clear in Linux:

On Windows, and macOS, this static function will use the native file dialog and not a QFileDialog.

It never mentioned Linux so I assumed it was using the QFileDialog, but I think it is now using the GTKDialog so I will try disabling this and see what happens. Thanks for your help

This is probably just a warning, not an error.

As far as I understand the "transient parent" is the window which the dialog should be placed on top of, otherwise the dialog could theoretically be move "below" the parent.
It should still work though.

So maybe it is trying to use the GTKDialog for the QFileDialog, and I get this error as it doesn't know how to use a QMainWindow for its parent.

This kind of window relationship is handled on the level of window system handles, e.g. X11 window IDs, so this shouldn't be a problem.

But of course there could be limitation on the integration API and/or bugs.

Cheers,
