<description><p>A tree event holds information about events associated with <seeerl marker="wxTreeCtrl"><c>wxTreeCtrl</c></seeerl> objects.
      </p><p>To process input from a tree control, use these event handler macros to direct input to member functions that take a <seeerl marker="wxTreeEvent"><c>wxTreeEvent</c></seeerl> argument.
      </p><p>See: <seeerl marker="wxTreeCtrl"><c>wxTreeCtrl</c></seeerl>
      </p>
  <p>This class is derived (and can use functions) from: 
    <seeerl marker="wxNotifyEvent"><c>wxNotifyEvent</c></seeerl> <seeerl marker="wxCommandEvent"><c>wxCommandEvent</c></seeerl> <seeerl marker="wxEvent"><c>wxEvent</c></seeerl></p>
