Question

Intermittant dialog draw proc CRASH

Hi,

I am developing Illustrator CS2 plugin for Mac using Xcode 1.5/OS 10.3.9. I have intermittant problem with display of certain dialog. I have overridden dialog's draw procedure with my own, which calls default draw and then adds some additional text and icon.

Usually it dislays fine.

Sometimes however, it starts to draw my text and then I get bad crash out of Illustrator. Some of crash log is below. Perhaps it is recursivly calling my display proc?

Tried debugging. I put breakpoint in my draw proc. First time it is hit, nothing shows up in Illustrator. After continue, dialog pops up and breakpoint is hit again (why?). Continue again, and back in Illustrator we can hit OK to dismiss dialog. Now breakpoint is hit a third time, after continue all is normal.

HELP please!

Chunky

Incidentally, I think there are bugs in Illustrator's support of custom drawing. For example, I occasionally get an Illustrator crash if I resize one of my dialogs that has a custom draw proc. I have never had a crash when resizing dialogs without custom draw procs.

It could be that there is a problem with my draw proc and Chunky's draw proc as noted above. However, there are many other issues with custom drawing that make me think it has not been tested very well.

This is probably not the problem - but since text is involved, it would at least be worth triple checking that your string's memory isn't getting overwritten somehow.

Also, I've had a similar issue with debugging a draw proc that may explain your situtation. When I hit the break point, my IDE window gets the focus. When I resume, the dialog repaints itself causing the break point to get hit again, etc... ad nausem...
