common variables between widgets [message #32699]

Hi there,

Iï¿½m a beginner to IDL with some knowledge of VB and C++.
Presently, I try to catch on to widget-programming and now encounter
some problems regarding the scope of variables.

My problem:
I want to load an image file by pushing a button and then manipulate
the image data using a slider. How can I allow the slider-procedure to
"see" the image data as loaded in the button-procedure?

Looking forward to your tips,
Holger
