We have 2 problems with part of our Motif application.
We have a pulldown menu with options that, when selected, manage a
Bulletinboard Dialog with a List and some Pushbuttons. One of the
Pushbuttons (Ok) when selected with the mouse invokes a callback
(ActivateCallback) that will unmanage the Bulletinboard Dialog (and
do other processing).
The first problem we have seen is that if the Ok button is double
(or triple) clicked, then when the BulletinBoard Dialog is managed
again (via pulldown) the Ok button shows it's Arm colour (looks
like it is selected) when the mouse pointer is on the button. I
assume that the Pushbutton set it's Arm colour for the second click,
and then the widgets get unmanaged by the callback from the first
click.
Is there a way that I can stop the second click from leaving the
Arm colour set? (Maybe unset the Arm colour when I manage?)
The 2nd, and more serious, problem is that the ActivateCallback
is invoked twice.
How do I stop the second callback? Do I have to keep a Time_Elapsed
variable and skip the callback processing if a specified amount of
time has not elapsed?.
Configuration:
Motif 1.0
