I've got a window that can be moved by clicking on the background
(it's irregularly shape, so it doesn't have a title bar). In that
window is a view which is basically circular (not opaque, only draws
and responds to a circular area in the middle of the view). The
problem is that this results in "dead spots" in the corners of that
view where I'd expect to be able to drag the window (like I can
everywhere else in the background).
The view returns NO for -isOpaque, and NO for -mouseDownCanMoveWindow
(since it needs to be able to track and respond to clicks in the
content). In order to handle the fact that the view is non-square,
I've implemented -hitTest: to see if the mouse is in the circular
"live" area, and return the view, and return nil for things outside
that (which results in the super-views hitTest routine to return the
superview).
I've even overridden the window's content view to determine that it's
hitTest: properly returns the content view when the user clicks on the
corner of the round view.
Nothing I've tried, however, allows the user to actually drag the
window while clicking in the corners of the round view. It's almost
as if the "can move window by background" logic goes by bounding boxes
only and doesn't actually call hitTest to determine what is clicked on
(to see whose -mouseDownCanMoveWindow it should pay attention to).
Everywhere else in the window, dragging works exactly as expected (so
the window's isMovableByWindowBackgound works correctly), but just not
those four corners.
Short of having the window's content view return NO for its
mouseDownCanMoveWindow and then add window moving to the mouseDown/
mouseDragged routines (which seems ugly at best), is there something
I'm missing?
