Hello,
What is the recommended way to repaint a canvas? Do i have to call the expose
function or is there another way to do it? The problem i have is like this:
I have to implement a zoom function. Every time i press a zoom button, the
canvas has to be redrawn with a new scale factor. What is best way to achieve
this.
(oh, i forgot the questionmark, sorry)
Thanks for your help
Peter
