Hi!
I'm trying to simulate a diffraction grating for my pupils. I have two scrolled-canvas: one for displaying the spectrum as colors, and one for showing its intensity profile.
The problem is that I want to make the first one to have a specific height
have you tried:
(ltk:configure (canvas scrolled-canvas-instance) :height size)
Bye! C.
