See-through custom NSView

Hi,

I know how to make e.g. a NSTextView transparent: Setting the window opacity to NO, no drawing of the NSTextViews background, etc. The result is that I can see through the view and through the window. I can see the objects underneath the window.

Now I tried to accomplish the same with my NSView derived class using the same method, playing around with the isOpaque method (returning YES gives a white background, NO the striped window background), but I could not achieve the same see-through effect as with the NSTextView. (In the drawRect method I do nothing, but it is there)

Any ideas what I am missing here or what makes my view different from a NSTextView?

Thanks,
  Michael
