Can someone explain how the volume slider works? I don't understand why the graphic is allowed to change like that. How is it attached to the volume of the music player?
I have a feeling that it has something to do with the fact that it is an 'xresource' png file. Are these special? I can't seem to find anything about them on the board.
I would like to have a simmular thing for a control of my lights. Slide the control up and down and have the dim level set.
Thanks,
Chad.
