System: freshly installed 12.2 64bit with KDE.
Problem: The Qt interface designer, Qt 4 Designer just won’t start up.
I have installed the pattern Qt development.
Qt Creator, Qt 4 Assistant and Qt 4 Linguist start up okay from kickoff menu.
However, the Qt interface designer, Qt 4 Designer won’t start up. After starting it from the kickoff menu, the system waits for the application with the mouse animation, but that’s all.
I’ve experienced a similar case with Virtualbox, when my user was not added to to the group ‘vboxusers’. But then I could do some debugging by starting the application from a terminal, and by the output error message it was easy to solve the problem. Unfortunately, I do not know how to start this program from terminal (I didn’t find it in /usr/bin).
Thanks, that’s a start. Started ‘designer’ from terminal brought up the program I was looking for.
However there are two new questions.
1.) Why Qt 4 designer won’t start from kickoff menu? Is it a well-known issue, or is it only for me?
2.) There is an interesting output on the terminal, is it okay?
Output:
Error while reparenting!

It starts on my machine from the menu, so that it does not start on
yours is not normal.

That’s typical useless noise from Qt programs, ignore it.
I cannot directly help with the question why the menu entry fails, but
you could lookup what command it invokes
The contents of my .destkop file is exactly the same.
Edit: normally I do not swear, but WTF…
I searched for design in kickoff, it listed Run: designer, and Qt 4 Designer.
The Run: designer worked just okay.
And after that, the Qt 4 Designer also started to work.
After restart, the bug returned.
So I can start Designer from kickoff menu after once started from terminal. Then it works okay. But I have to do it after every boot.

That sounds absolutely weird, no idea how to diagnose that, what version
of libqt4-devel do you have (designer is part of that package) and is
this version the same as the versions you see for the other qt packages with
rpm -qa '*qt4*'
?
This is so far my only idea here that something has a inconsistent
version and leads to such a funny side effect.
Other than that I am clueless.
