Hello,
Is there a way to ensure that my modal dialog widget will fit on any display
screen? I have a modal dialog which is arranged in a column. On most displays,
the whole widget fits on the screen. But on some smaller displays, the widget
is too tall to fit on the screen, and thus, the "OK" button at the bottom of the
widget cannot be selected.
I realize that I could arrange the widget into two columns so that it is shorter
and wider. But what I'm really interested in is a general way of ensuring that
a dialog will fit on any screen. Should I check the screen size and check the
size of the top level base and rearange the dialog if necessary? Can you add a
scroll bar to a dialog? Any other ideas?
Thanks!

Sorry for giving you bad advice! The manual I looked it up in is for IDL
3.0, and doesn't even mention the /modal flag. I should have looked it
up in the online help, which is more up-to-date. Better yet, I should
have tested it before saying anything.
One alternative would be to apply the /scroll option to a sub-base of
the modal base. Obviously, that will make the widget a little more
complicated.
However, I still stand by my third piece of advice: any really large
widget might benefit by being broken up into sub-widgets.
