[Gambas-user] Panning a picturebox inside a scrollview with mouse

[Jesus Guardon]

Many thanks Steven for your input

I have solved this issue using a drawingarea object instead a 
picturebox. I've stated than it is much less cpu consuming, because the 
image --a big world map-- I want to show, needs to be updated 
periodically by other shell command that modifies it with texts and 
lines, and must be loaded everytime. After a bit of thinking, I prefer 
don't update the map itself, and draw over it, instead. Here is what 
I've done so far; you can use the mouse to pan the image around.

#See attached project#

In the meantime I will take a look to your example, I'm sure it will be 
very helpfull.

Thanks again

Regards

Jesús
