The old stack I have uses a technique of switching the tool from the browse tool (when a user need to click on tool icons or menus or whatever to the appropriate vector drawing tool when the mouse is over the drawing area, including the pointer tool for selecting, dragging, or resizing existing graphic objects created using other tools. The difference is, in the old stack under LC4.6.4 of an object is selected (say a rectangle) and the tool is set back to browse to click on a color palette (or whatever), the object remains selected. However, under LC9 it does not. Or if it is something in the old code of the stack I can't figure out what. That's why I am looking for an example to learn from. I'd appreciate taking a look at your stack. ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode

Re: Help with drawing in LiveCode...
I implemented a fairly complex drawing module to a stack we use all the time. It isn't CAD, but it looks like it, albeit rather less professional looking than, say, AutoCad or SoldWorks would produce. We send these drawings out daily to clients. They are based on data calculated within the stack, and use graphic objects galore. But our drawings are one-way, that is, once drawn, they are complete, and are forwarded as PDF's. You are looking to be able to manipulate objects (in CAD parlance) live on screen.
