GtkDialog mapped without transient parent

Re: "GTK" warning for Native QFileDialog under Linux

Hi,

Is there still no fix/workaround for this? Terminal output is important to my program and I have searched for a way to disable/fix this warning to no avail. (See original post.)

Is there a different file picker available in Qt that I could use in lieu of QFileDialog::getOpenFileName to resolve this issue? I'm kind of new to Qt.

Thanks!

Hi and welcome to devnet,

As an alternative, you can use the non-native version of the dialog.

@sgaist said in GtkDialog mapped without transient parent:

My thoughts exactly, but I couldn't quickly locate the docs for native vs non-native dialogs and didn't want to post a falsehood. Also, using a desktop manager that is not gtk based may alleviate this problem, as gnome/gtk has a well known history of doing things their own way with complete disregard for the rest of the world or the problems they may introduce.

BTW: if this problem is just a case of not wanting to see the warnings in an xterm then the OP can run the app in an xterm where stderr has been redirected to a file or /dev/null. That should make all qt program warning dissappear from the xterm session. Actually, if it were me I'd run xconsole and direct stderr to that window.

Hi all,

Thanks for the helpful responses. Here's the doc link for anyone else facing this issue:
https://doc.qt.io/qt-5/qfiledialog.html#getOpenFileName

The relevant option is QFileDialog::DontUseNativeDialog, detailed here:
https://doc.qt.io/qt-5/qfiledialog.html#Option-enum

Passing this option solved the issue (and I'd say I like the non-native dialog better!)
