I seem to be having widget timing problems in IDL under
NT. When an event triggers a call to an event handler in
my code it seems that the event handler is called 4 times
for every event trigger. E.g. if I have some code in my
event handler like...
case event.tag of
push_button: print, 'Big deal you pushed the button'
toot_your_horn: ; do nothing
endcase
every time I push the button the above message gets printed
4 times. This is a real problem when I do things like fire
off another complicated (modal) widget interface from the
current one, to e.g. collect information from the user; i.e.
the user will get a little frustrated filling out a
complicated form identically 4 times (how do you feel when
you have to fill one out once ?!) There's a good chance I'm
just forgetting to set something but I can't figure out what
(this seems to happen regardless of how complicated my widget
program is, including just using e.g.'s from the docs)
Has anybody else had this problem and have any suggestions ?
(BTW if it matters my machine is a 100 MHz pentium) Thanks
for any thoughts,
-- KY
