c# - PInvoke of NetUserAdd returns 24 -

NSSegmentedCells, there are no mouse tracking processing when the NSCell subclasses are done, on one hand, mouse tracking, which only starts when the control is clicked. So the question is, how do I process mouse events properly, either in NSSegmentedControl or in the NSSegme...
