I've Been HAcking!!! I've been trying to setup a custombitmap'd custom screen, using a bitmap larger than the view port. This part works fine. ..I was hoping to be able to make a 'virtual workbench'... along the lines of MWB, but allowing for 'virtual' screens much larger than the viewport size (e.g. 960x960 BitMap when the actual viewport is only 702 x 330 or something)... and then allow the user to 'paw around' in this virtual screen. However, I've run into some problems... I can move the viewport's window on the screen around no problem (Ala MakeScreen/RethingDisplay), but Intuition doesn't handle it right: (A) Intuition doesn't offset the mouse coordinates properly When your viewport origin is something other than the upper left hand corner of the bitmap. (B) Intuition doesn't allow you to move windows past the viewport border (702), even though the bitmap might be 900 across. I have been unable to find what Intuition uses to check that a delta move stays within bounds... I've tried Everything! All the screen BitMap's and RastPort's seem to be geared to the extra large custom bitmap. I can't figure out where Intuition is getting the 702 from (I've even tried changing the Screen->Width after openning!!!). Both (A) and (B) Would be a *real* simple fix for 1.3.... Intuition need simply check the RxOffset and RyOffset in the RasInfo structure, and use the BitMap for bounds checking valid window positions. Can somebody at C-A help? If not with a solution, how'bout with a description of what Intuition is *actually* doing??? You've got to admit, it's appealing to be able to shove your windows all the way off your screen!
