Widgets and Animation Loops in IDL 5.0 [message #16387]

Hi,
I am using IDL 5.0 on a DEC Alpha. I am animating a 3D plot of a
particle trajectory by incrementing the "az" variable and then
replotting in a loop. I decided to add widgets to control the speed of
rotation and the angle about the x axis "ax". I have found this to be
unworkable so far because once the code enters the loop the widgets do
not issue events, so my event handlers do not get called. This was
easily fixed by using widget_control commands inside the loop and using
sliders to control the speed and x angle, however, I can not find a
method to exit the loop, except for possibly adding a slider that could
turn it off. The solution seemed to be a toggle button that could be
examined using widget_control during the loop, but I have found no way
to examine the state of the toggle button. Also while I am at it, I am
new to 3D plotting using "plots" to do a trajectory plot. There seems
to be no way to get axis on the screen. I have tried the axis command
and can only get either one axis, or a white blotch (this seems random
as I have not touched that line of code for a while). So help on any of
the above will be greatly appreciated.

Thank you,
Shawn
