how to "check" checkbox state? [message #60179] Tue, 06 May 2008 09:05

Hello everybody,

I am writing a GUI program using the IDL GUI builder. I put a checkbox
on the GUI, and that checkbox state should be checked when a specific
button is pressed. The code is handled inside the x_eventcb.pro file.

Question is: How can I check the state of the checkbox (checked/
unchecked)? Can somebody give me an example?

I've read through the IDL help and several topics on this newsgroup,
but I couldn't a fitting solution for my rather simple problem.

I know how to set the state with "Widget_control, buttonname,
set_button = 1" but since there is no "get_button" I'm quite puzzled
how to get the state.

Any help would be greatly appreciated!
