through kmenuedit i can set new menu items and icons... however, once the application starts, it uses its own icon (which has been set elsewhere, i guess). how do i set a different icon for that application?
Any KDE application has the capability of loading and using a different icon than the built-in one on application start. Use the
--icon option. See the
--help-all option for further customisations.
It think there is no general solution for this since the application sets this icon itself, AFAIK. However it might be possible to replace this icon for a specific application. For this I would have to know what application's icon you want to change.
