Is there any public or commercial utility to organise a set of MacDraw-like tools allowing the construction of Hypercard cards of movable graphical objects. Preferably, the objects would behave as HC buttons and have scripts attached. If there is no such tools available, how difficult would it be to interface an XCMD to an independent program window and to control all the graphics behaviour from HC? I tried to trick HC into doing sort of primitive object-graphics with buttons. So far I managed to construct a few object-like buttons, e.g. lines and polygons, I am having quite a few problems refreshing the card as draging objects across, or worse tracking the mouse clicks into a particular button (if rectangular buttons are used as hosts for lines and polys then they are going to overlap, quite a lot). Perhaps HC 2.0 solves all these problems and provides an extensive set of button shapes? Perhaps the window and program interface is better? I am new to Hypercard so perhaps I missed something out?

Preferably, the objects would behave as HC buttons and have >scripts attached. I have written an XCMD polygon button handler for HC 1.2.5 that does about half of what you want. The polygons are all transparant autohilite--drawing non-transparant objects on a hypercard card is not feasible, as there is no easy way to give your XCMD's update events. Tail-patching WaitNextEvent would work--if tail-patching in general worked, which it doesn't. If anyone has any ideas about drawing on HC's card in non-XOR mode, I'd like to hear them too. My XCMD detects clicks on the polybuttons by intercepting mouseDown events on the card or bg layer, building a region for each polybutton, and checking PtInRegion to find hits. This process is actually pretty fast--it takes about 20 ticks from the mousedown event until the time the polybutton's script takes control. If anyone is interested in this XCMD, I might clean it up and post it. Some manual setup is required. -- ___\ /___ Greg Anderson ___\ /___ \ \ / / Advanced Technology Group \ \ / / \ /\/\ / Apple Computer, Inc. \ /\/\ / \/ \/ greggor@apple.com \/ \/
