- I need to be informed of the position of the scrollbar
- (precisely the SCROLLBAR_VIEW _START) whenever i do
- scrolling. I need to know this so that i can append
- the next image to the canvas when the scrolling reaches
- a certain point. I have tried to do this by making
- CANVAS_RETAINED to be false. But this means that every
- time i click on the scrollbar, i have to wait for the
- canvas repaint program to paint the exposed area. This
- is rather slow. I want to be informed of the scrollbar
- position but not by the canvas repaint program.
-
- I hope someone can help me out.
-
- Thanks in advance.
