When we click into the CheckBox the following effects are being enabled:
*kwin4_effect_desktopgrid
*kwin4_effect_presntwindows
*kwin4_effect_dialogparent
If one of the above effects gets disabled, then the checkbox is unchecked.
Our CheckBox can detect if our effects are enable at the start time.
Only ONE of the following effects can be active at the same
time.
*kwin4_effect_slideEnabled
*kwin4_effect_cubeslideEnabled
*kwin4_effect_fadedesktopEnabled
