I worked out that the Eye Control plugin sample crashes in the drawing code
when using Cocoa and it runs okay when compiled for Carbon.
Now I placed the code you suggested in the openFunction
and I do at least get valid height and width for my plugin control.
The problem is that regardless of whether I use Carbon or Cocoa
I am always getting nil returned by REALGetControlHandle()
I think this is because only objects based on RealControl have the Handle
property.
For the moment I am resorting to a workaround of also placing an extra Canvas
object
on my Window and passing the handle of that Canvas object to my control.
How can I make my control to inherit the properties of a RealControl object ?
