+ Processes a @c wxEVT_GRID_CELL_CHANGING event type.

+ call to SetGridCursor() or GoToCell(). Processes a
+ @c wxEVT_GRID_SELECT_CELL event type.
+ @event{EVT_GRID_COL_MOVE(func)}
+ The user tries to change the order of the columns in the grid by
+ dragging the column specified by GetCol(). This event can be vetoed to
+ either prevent the user from reordering the column change completely
+ (but notice that if you don't want to allow it at all, you simply
+ shouldn't call wxGrid::EnableDragColMove() in the first place), vetoed
+ but handled in some way in the handler, e.g. by really moving the
+ column to the new position at the associated table level, or allowed to
+ proceed in which case wxGrid::SetColPos() is used to reorder the
+ columns display order without affecting the use of the column indices
+ otherwise.
+ This event macro corresponds to @c wxEVT_GRID_COL_MOVE event type.
+ @event{EVT_GRID_COL_SORT(func)}
+ This event is generated when a column is clicked by the user and its
+ name is explained by the fact that the custom reaction to a click on a
+ column is to sort the grid contents by this column. However the grid
+ itself has no special support for sorting and it's up to the handler of
+ this event to update the associated table. But if the event is handled
+ (and not vetoed) the grid supposes that the table was indeed resorted
+ and updates the column to indicate the new sort order and refreshes
+ itself.
