SUMMARY Although the click mode in KDE-settings is set to Single Click, dolphin needs a double click to open files and directories running the Mate desktop. Running KDE desktop the click mode works fine. STEPS TO REPRODUCE 1. Install openSUSE, dolphin, MATE DTE 2. Change to MATE desktop on login 3. open dolphin OBSERVED RESULT Double click working EXPECTED RESULT Single click working SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: Leap 15.1 (available in About System) KDE Plasma Version: KDE Frameworks Version: Qt Version: ADDITIONAL INFORMATION The same behaviour appears running Ubuntu with Mate. Is it possible to set the click mode within the dolphin settings, like other file browsers do it? Among them dolphin is the best for me, but the double clicking is annoying if all other actions to open items work with a single click.
I think this is intentional, and Dolphin attempts to respect the click style of alternative desktops when run outside of Plasma. It would be really weird if Dolphin used single-click in MATE even though Nautilus and the file dialogs and other GTK-based software did not.
It is also possible that MATE doesn't ship with a Qt platform plugin at all, so it cannot get the settings of that environment. Possible solutions: * use qt5ct as a configurable Qt platform plugin for desktops that don't provide one * start KDE applications with XDG_CURRENT_DESKTOP=KDE environment variable to force loading Plasma's Qt platform plugin.

Thank you for this quick response. I tried it, but it didn't help. The XDG_CURRENT_DESKTOP environment variable doesn't show any difference running dolphin if set to MATE or KDE. Setting the click mode in KDE-settings, this results in changing the file ~.kde4/share/config/kdeglobals: SingleClick=true or false It seems that this configurtion is not used by dolphin.
