I'm trying to replicate a brush tool much like the Artisan brush and the Shave and a Haircut brush. I have an MPxContext set up and working fine and the actual brush functionality seems to be working fine, I would just like to render the opengl red brush ring for visual feedback. I want this to be visible and follow the mouse around whether the mouse button is pressed or not. I scoured the docs and couldn't fine any mouse move callback. MPxContext has doPress, doDrag, doRelase, and doEnterRegion but no plain mouse move event or callback. I noticed on Shave and a Haircut's brush tool that when you enter the context, it creates some dummy transform called shaveBrushProxy that follows the mouse around in the projected viewport coordinates so there has to be some sort of callback or hook I can use. Anyone have any ideas?
