I'm doing a project,about image processing.But I don't know how to how
to exchange variable between modal dialog and the main window.I can't
find more material about the message exchanging in IDL windows.Could
someone can help me?
Now I use the GUIBuilder,in main window,put a button and make a
procedure like this:

pro OnPress,event
dlggui,group_leader=event.top
end

dlggui is another procedure,with
files:dlggui.pro,dlggui_event.pro,dlg_gui.prc.

I don't know how I can transfer a variable or point A from main window
to dlggui,I want to change the value of dlggui,in main program.

thanks.
