Description of problem: If you set change the settings in Dolphin to "Double-click to open files and folders", it only works in Dolphin itself, but is not applied on the desktop (the folder view widget). Version-Release number of selected component (if applicable): KDE Plasma 5.4.2 Dolphin 15.04 How reproducible: Always Steps to Reproduce: 1.Open Dolphin Settings 2. In "Navigation" set Mouse to "Double-click to open files and folders" (Single-click is default). 3. Single-click on a destop icon. Actual results: The program or folder you clicked will open. Expected results: The settings should have also applied for desktop symbols, so it a signle-click should only mark them like Dolphin does. Additional info: It behaved as expected in Fedora 21, which ships with KDE Plasma 4.
It behaves as expected in Fedora 23 again, as there are no such setting in the dolphin settings anymore. I found the "mouse behavior"-setting in "system settings" > "Input devices" here. I'll close this bug.
