I've mentioned this before, but now after some investigation, I need to ask again.
AUSampler is one of the few examples of Apple-provided AU's on Lion that feature new controls which pop up a new window when manipulated. I recall that many of the standard plugins in Mountain Lion now have these controls in their views.
I've verified that these windows exist as NSWindows, not just NSViews, that they have no parent window, and no title.
What is the relationship of these windows to the window containing the AU View, and how is a host supposed to ensure that they are removed from the screen when the AU View-containing window is removed? In addition, how is the host supposed to ensure that they move with the AU View-containing window when it is moved, since currently they do not ...
As a side note, I've also verified that the view for AUSampler resets its origin within its superview when the "Show Editor" control is clicked. I have no idea what this behaviour is supposed to accomplish, since it also resizes its frame to accomodate the new controls it wants to display.
I'd really, really appreciate a comment on this from someone inside Apple who can comment on what these new control windows do and how a host is intended to handle them.
thanks,
