Hello Again,
Thanks for the help, those examples are from Tame, they are on the net for a while, did check them but, cannot use them, the reason is the following:
i have te make thumb couples, the slider has is used to see cutted fragments from a videoplayer,
if the movie is cutted is 3 parts, i see 6 thumbs on it, when i click one thumb, (fe startframe) the couples thumb(stopframe) has to be highlighted and track between must be colorred.
when i dras a thumb it must send an action to another panel, thats why i need a listener.
i send some code with this reply maybe it is easier to see
