[SOLVED] Missing icons in QT5 designer

re_nelson · 05-23-2018, 06:15 PM

I have both QT4 (4.8.7) and QT5 (5.10.1) installed on my BLFS/SVN system. Only recently have I noticed that some of the toolbar icons are missing ONLY on the QT5 instance of designer, falling back to the generic image.

The build and installation of qt-everywhere-src-5.10.1.tar.xz was error free and, thus, I can't account for the missing toolbar icons.

The screenshots show designer, both QT4 where all are populated and QT5, where some are missing.

Has anyone else come across a similar problem or is your QT5 designer toolbar filled with the appropriate icons?

Looks like it switched to generic ones. Try creating some symlinks and/or check your QT_QPA_PLATFORMTHEME environment variable, it is most likely related to whatever is managing your desktop theme.

That was the remedy for replacing the generic icons with those that are task-specific. Setting QT_QPA_PLATFORMTHEME=qt5ct enabled all of the icons. Alternately invoking designer with this option also solved the problem: --platformtheme qt5ct.

I'm marking the thread solved, attaching a screenshot showing the fully-populated icons as proof and thank you, a fellow Texan, very much for the pointer.
