[Octave-bug-tracker] [bug #54607] Native (KDE) open/save dialogs are not used

[Kai Torben Ohlhus]

Follow-up Comment #41, bug #54607 (project octave):

Thank you for all the feedback.

Comment #36: Now I really tried a clean installation to /usr/local, removed
everything in my home directory, especially the folder ~/.config/octave with
qtsettings (I almost stick to the default settings anyway...) But no change
:(

One observation here: when the starting first time save as-dialogue hangs (~5
minutes), or at any subsequent call (1 second), a process of 

/usr/lib64/qt5/plugins/kf5/kio/file.so

starts and vanishes some time after closing the dialogue.

Comment #39:

> ... using Gtk or non-native Qt dialogs in KDE is a pain in comparison to the
native dialogs. I think any KDE user would say similarly. 

> I really hope this improvement is not reverted. I also hope remaining issues
are fixed, of course. 

I agree with you completely, too, and want them to work.  But it is not the
case for me, so I propose an option to opt-in non-native-dialogues in the hope
this option becomes deprecate in a near future.

Comment 40: Even nothing to win here.  I tried to copy and paste the demo code
from the tutorial (disregarding any functionality) from the official tutorial
[1] into Octave [2] and recompiled.

It is like witchcraft: The stand-alone tutorial works like a charm, in Octave
[2] the very same code causes this hangs.
