For some small places dealing with program configuration, I am using a TTreeView descendant in some of my project. However, my code for checking if a stateimage (used to simulate check boxes) has been clicked (WMLButtonDown/Up) does not work on anyhing but Windows since it uses Treeview_HitTest / TTVHitTestInfo
Any ideas for solving this on Mac/Cocoa platform?
Searching Google I found CarbonHitTest ... inside a Cocoa unit
