hi @ll, i have just a question about BasicSliderUI. I wrote a class which extends from BasicSliderUI to have a knob for toggling. Actually I noticed that I have to disable the knob on Startup of the application because of possible wrong usage. the knob is disabled (no move can be done), but it appears like enabled. so my question is, which method(s) do i have to override, or what do i have to add in paintThumb and paintTrack, that there can be seen a change.
