- Methods for a registry for mapping data types to Renderers/Editors
+ Register a new data type.
+
+ The data types allow to naturally associate specific renderers and

+ wxGRID_VALUE_STRING which uses wxGridCellStringRenderer and
+ wxGridCellTextEditor as its renderer and editor respectively -- this is
+ the data type used by all the cells of the default wxGridStringTable,
+ so this renderer and editor are used by default for all grid cells.
+
+ However if a custom table returns @c wxGRID_VALUE_BOOL from its
+ wxGridTableBase::GetTypeName() method, then wxGridCellBoolRenderer and
+ wxGridCellBoolEditor are used for it because the grid also registers a
+ boolean data type with this name.
+
+ And as this mechanism is completely generic, you may register your own
+ data types using your own custom renderers and editors. Just remember
+ that the table must identify a cell as being of the given type for them
+ to be used for this cell.
+
+ @param typeName
+ Name of the new type. May be any string, but if the type name is
+ the same as the name of an already registered type, including one
+ of the standard ones (which are @c wxGRID_VALUE_STRING, @c
+ wxGRID_VALUE_BOOL, @c wxGRID_VALUE_NUMBER, @c wxGRID_VALUE_FLOAT
+ and @c wxGRID_VALUE_CHOICE), then the new registration information
+ replaces the previously used renderer and editor.
+ @param renderer
+ The renderer to use for the cells of this type. Its ownership is
+ taken by the grid, i.e. it will call DecRef() on this pointer when
+ it doesn't need it any longer.
+ @param editor
+ The editor to use for the cells of this type. Its ownership is also
