Customizing balsa (scrolling while selecting)

[Philip Van Hoof <freax pandora be>]

Hi there,

I am customizing balsa a little bit .. I want the preview window to scroll
down when I reached the end of the window while selecting. At this moment I
added a few signals so that when I am pressing and moving my mice over the
window->preview widget .. I get a message like :

You are pressing left mouse button and moving [139, 295] 
 or 
You are pressing right mouse button and moving [139, 295]

(It's in the patch that is attached).

Only thing I still need is to detect wheter I am at the bottom or top of
the preview widget with my mouse pointer and how to "move" the scrollbar of
the preview widget. Can somebody help me with that ? (check the attached
patch. Once patched -against current cvs- the motion callback function is 
at position 2868 called "preview_motion_cb").

*Note* that I am not trying to make an "official" patch so no flamewars 
about the feature that I am adding :). Unless ofcourse the balsa 
maintainers are intrested in the patch... but this one is at this
moment for my personal use. I have my reasons to fix this issue for
me .. ;) so again : no flaming.
