One way would be to do this just like you wrote. Did you try this? scroll->type(0); // disable scrollbars scroll->xposition(int); // scroll horizontally scroll->yposition(int); // scroll vertically scroll->position(int,int); // scroll to an arbitrary position (FLTK 1.1) scroll->scroll_to(int,int); // dto. for FLTK 1.3 to position the scrollable area. I didn't try this, but according to the docs this ought to work. Of course you can use real buttons to change the scroll position. However you won't be able to do smooth scrolling easily. Another way would be to implement mouse dragging. If necessary you may put a transparent box over the scroll area and catch the mouse events to do dragging. Then you can position the scroll area as described above. For an example how to drag an object you can look at Greg's cheat page: http://seriss.com/people/erco/fltk/#DraggableBoxes http://seriss.com/people/erco/fltk/#ClicksOnScrollableBox Albrecht _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
