+ @c wxEVT_GRID_LABEL_RIGHT_CLICK event which simply does nothing (in
+ particular doesn't skip the event) as this will prevent the default
+ right click handling from working.
+
+ Also note that currently @c wxEVT_GRID_LABEL_RIGHT_DCLICK event is not
+ generated for the column labels if the native columns header is used
+ (but this limitation could possibly be lifted in the future).
