I don't often work with IDL so please bear with my sloppy terminology.
I'm trying to learn a little about object graphics. I'd like to make
my widgets resizable, but I'm obviously missing something. The following
program (based on some code from the IDL examples and David's web site)
resizes the way I'd like on my PeeCee, but not when using X (on HP-UX or
VMS). On the PC, when I expand the size of the widget the graphics
display expands to fill the widget. Using X the graphics display stays
the original size in the lower left corner (but the "black drawing area"
expands to fill the widget). I'm using IDL 5.3 on all systems (well,
actually, the PC has 5.3.1.)
What do I need to do to make resizing work on X devices?
Thanks,
Dave
