Oh, right, you want to turn it OFF, too. :-)

Typically, we keep some kind of a timer flag in the info
structure. We turn the flag on when we start the timer:

info.timer_flag = 1
IF info.timer_flag THEN Widget_Control, info.tID, Timer=0.5

Then, if we hit the STOP button (or whatever it is that is
suppose to stop the timer) then we do something like this:

info.timer_flag = 0
Widget_Control, info.tID, /Clear_Events

In this way, the next timer event cannot get generated.

Cheers,

David
