Dear Maintainer, Despite having set "Single-click to open files and folders" in System Setting, dolphin opens them only by double clicking. Single click just selects the file the pointer is over. Elements in Folder view widgets on the desktop do open with single click. This is a regression to the version in stretch. I don't know when this regression appeared. This might be related to bug #800311.
I no longer have the buggy behaviour. The dolphin package is of the same version, some dependencies have been updated since the report. Best wishes, Gábor
Dear Maintainer, the bug is still present, just encountered the same behaviour in 'bullseye'. Single-click doesn't work neither in Dolphin, nor in Desktop Folder View. Even tried to create a fresh user after reboot — to no avail.
As in my case, gwenview didn't respect the single-click setting either. So, probably, it's some more global configuration inconsistency in plasma, kde5 or qt5. Removing `qt5ct` along with it's user config, and setting explicitly `[KDE]/SingleClick=true` in `.config/kdeglobals` fixed it for me.
