Instead of trying to determine the type of the value which should be extracted from the NSObject we receive from NSOutlineView, just pass it to a virtual method in the renderer which knows which type does it need. This fixes the problem with editing boolean/checkbox columns and makes the code more elegant. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@62490 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
