Hi everyone!
I'm using IDL v3.6.1.
In an application of mine I'm using a WIDGET_DRAW with /scroll
(only vertical) to display large images.
Now the customer wants an automatic mode, causing the
image to be automatically scrolled (smoothly) from
top to bottom without ANY user interaction.
I first thought of setting the value of the scrollbar
in some way - but I have no reference to the scrollbar,
only the widget_draw itself (And it has no children).
Does any of you GURUs have a clue?
Hopefully waiting for suggestions...
