Sorry, that I couldn't answer yesterday.. Well, thanks a lot for your
answers. I tried to do like it was described but it still doesn't
work. Maybe I give a small example code, which makes it clearer, what
i mean and what I want to do.
My main program/widget has an event which opens a modal widget:
pro MFiOpenData, Event
COMMON widget_id, win2
win2=widget_info(event.top, find_by_uname='Window2')
openfile, group_leader=event.top
end
Now in the modal/popup widget i can upload some data, but when i want
to leave my modal widget again, and change/return back to my main
widget, the main widget shoud activate some green lamps on my main
widget. I tried to do it with this Event on my modal widget:
pro OKButton, Event
COMMON widget_id, win2
widget_control, win2, GET_VALUE=win2
wset, win2
green = read_bmp('green.bmp')
tv, green, true=1
widget_control, Event.top, /destroy
end
the problem is, that when i want to make it this way, the compiler
says
WIDGET_CONTROL: Class of specified widget has no value: 36
So is there any other possibility how to handle with it? Because I
still don't know how to control the main widget from my modal widget.
greetings
martin
