I've been thinking about some ideas and would like to add custom 'overlay' views to the canvas. I don't mean actual layers, but rather views that 'float' above the layers. Something like in the image below:
I'd imagine these overlay views would be normal NSViews. Importantly, I'd like them to be anchored to the position within the underlaying canvas so if the canvas is moved, they should naturally move with it.
I've tried adding them as subviews to MSContentDrawView, etc but didn't achieve the desired result
Is this possible to do? Any suggestions on where to look?
Thanks a lot!
