"GTK" warning for Native QFileDialog under Linux
-
Hi,
From a quick look, it doesn't seem there's anything that can be done currently see here.
@SGaist
Thank you for that. I note that the call seems to be:gtk_file_chooser_dialog_new("", 0, ...)That
0is forparent, which I understand to be the cause of the warning. Seems strange that the "parent" we pass toQFileDialogfunction does not get passed down to native dialog call? -

Because it can't. GTK does not know anything about any Qt classes - so it cannot use Qt classes as parents.

Sorry, yes, I meant, when we pass a Qt parent widget as parent to QFileDialog it would pass the corresponding native window onto GTK level as parent. But I don't know anything about GTK!@JNBarchan But since it is a Qt application there is no native GTK window. Qt does not use GTK on Linux - as far as I know it draws by itself.

@mrjj Yes, the native dialog is GTK, but there is no other GTK window to use as parent, right?

Ah, now it is beginning to become clearer! I think you're saying:- The native file dialog is a special kind of window: a "GTK" window. (This applies to Linux/X11? Ubuntu? Unity desktop only?)
- It would like another GTK window as its parent.
- But the Qt window which is its parent in
QFileDialogis not a GTK window. - So the code passes
0/NULLfor the parent, and that causes the warning.
Right?

@JonB Yes, if you use native dialogs on Linux then Qt simply uses GTK dialogs (GTK is isn't related to Unity, see https://www.gtk.org/). Yes, as GTK does not know anything about Qt it is not possible to pass a parent to GTK dialogs from a Qt app.
