A lot of the checkboxes in QtCreator's "New Class" Wizard are uncheckable when using the framework integration. When I click them, the "checking" animation shortly appears, but the checked state is quickly reverted to "unchecked" again. Unsetting the KDE_FULL_SESSION env. variable or uninstalling the "frameworkintegration" package fixes the issue. I checked if maybe the "Breeze" style is responsible, but running QtCreator with KDE_FULL_SESSION unset while forcing the Breeze style works as expected. I would like to find out where the real issue is, but I don't know how to get proper debug output from QPA/frameworksintegration or load/unload individual QPA plugins.
I'm having the same problem in Arch Linux with Plasma 5.4 and Qt Creator 3.5.1. Your workaround works here too.
I'm having this issue here, also running Arch Linux, frameworkintegration 5.18.0-1 plasma 5.5.3-2 qt-creator 3.6.0-1 breeze 5.5.3-1 qt 5.5.1
Confirm the problem with: frameworkintegration 5.19.0 plasma 5.5.5 qt-creator 3.6.0 qt 5.5.1
Confirming on Arch: qtcreator 3.6.0-4 plasma 5.5.5-1 qt 5.5.1-10 frameworkintegration 5.19.0-1 Unsetting KDE_FULL_SESSION wasn't enough, had to unset XDG_CURRENT_DESKTOP also as a workaround (uninstalling frameworkintegration works, too). Of course this changes the application's visual appearance.
Still present on Arch : qtcreator 4.1.0-1 plasma 5.7.4-2 qt 5.7.0-2 frameworkintegration 5.25.0-1
I can confirm this behaviour too, it's also present when creating a new QtQuick project. Arch, qtcreator 4.1.0-3 frameworkintegration 5.26.0-1 qt5-3d 5.7.0-1 qt5-base 5.7.0-2 qt5-canvas3d 5.7.0-1 qt5-connectivity 5.7.0-1 qt5-declarative 5.7.0-2 qt5-doc 5.7.0-1 qt5-graphicaleffects 5.7.0-1 qt5-imageformats 5.7.0-1 qt5-location 5.7.0-1 qt5-multimedia 5.7.0-1 qt5-quickcontrols 5.7.0-1 qt5-quickcontrols2 5.7.0-1 qt5-script 5.7.0-1 qt5-sensors 5.7.0-1 qt5-serialport 5.7.0-1 qt5-svg 5.7.0-1 qt5-tools 5.7.0-1 qt5-translations 5.7.0-1 qt5-wayland 5.7.0-2 qt5-webchannel 5.7.0-1 qt5-webengine 5.7.0-3 qt5-webkit 5.7.0-1 qt5-websockets 5.7.0-1 qt5-x11extras 5.7.0-1 qt5-xmlpatterns 5.7.0-1
Is the issue still the case?
While quickly testing the "new class" wizard, the bug hasn't occurred to me again. I haven't tested QtCreator thoroughly, though. env: KDE_FULL_SESSION=true XDG_CURRENT_DESKTOP=KDE Arch Linux: qtcreator 4.6.2-3 plasma-desktop 5.13.3-1 qt5 5.11.1-1 frameworkintegration 5.48.0-1
