The trouble is, your question is actually more nebulous than you think it is.
There are (at least) 3 issues that may or may not have their own subtleties:
1. Geometry.
2. View hierarchy.
3. Initialization timing.
The short answer is that you need to set your view's *frame* rect to the
*bounds* rect of the ancestor view you want to match. The ancestor view in this
case is the window's content view (which is the root of the window's entire
view hierarchy).
This is easy if your view is a subview of the window content view. If it's
merely a descendant view (subview of a subview, etc), then you need to do a
coordinate transformation from the bounds coordinate system of the ancestor to
the bounds coordinate system of the immediate superview.
Of course, this needs to be done at a time when the window already exists,
otherwise the requisite geometry may not be available. And you should follow
the rules/conventions/patterns for initialization that view subclasses
generally follow.
All of this is clearly documented:
