I put an NSScrollingView in the center of a window, leaving some
border to
the left and to the right. I put an NSView within a NSScrollingView.
Within this NSView, scrollable, I put several graphic objects MYObj,
subclass of NSViews. Then I define an NSCursor for each MYObj within
the
resetCursorRects method.
Everything works well. When I rollover the objects I can see
theCursor.
Now I scroll the scrollingView horizontally such a way an object
goes hidden
out of the scrollingView , let's say at the left side or the right
side out
of the scrollingView. Well, now if I rollover the mouse just on the
window,
out of the scrollingView, I still see the cursor. It seems that the
mouse
detects the position of MYObj even when not visible in the scrolling
view,
due to the scroll.
Have you considered the following from the documentation of
addCursorRect:cursor: ?
Cursor rectangles aren’t subject to clipping by superviews, nor are
they intended for use with rotated views. You should explicitly
confine a cursor rectangle to the view's visible rectangle to
prevent improper behavior.
See also NSIntersectionRect().
