One widget worked like those force sticks in the middle of the laptop keyboard: the user clicks and holds, the mouse pointer "becomes" the stick. Now the further the user moves the mouse to the right, the faster the video would run. If the widget is on the right edge of the screen, you could not fast forward, so I repositioned the invisible pointer after each drag event, counting only the deltas. With a pen, the deltas become huge, so the video "runs away" quickly. Another solution was the roller, again with a hiden pointer. Repositioning the pointer would create thise endless rolls. The last attempt was basically a Dial, but one could rotate it by simply making circular motions with the mouse. The ide was, that you would not have to make sure that the mouse stayed inside the Dial. You only had to hit a tiny dial to start the motion and then do the gesture. Again, with a pen in absolute position mode, that does not fly well (it could be solved though). >> I stopped assuming that everyone uses a three button mouse with a >> scrollwheel.

Yes, some for me. This particular person draws with a pen *and* even does 3D modelling with it. Amazing. For CAD, I prefer the 16-button "puck" ;-) <http://gis.esri.com/library/userconf/proc01/professional/papers/pap894/p08943.jpg > ---- http://robowerk.com/ _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
