Instance Method

insertColumn:

Inserts a new column of cells at the specified location. .

Declaration

- (void)insertColumn:(NSInteger)column;

Parameters

column: The number of the column before which the new column is inserted. If column is greater than the number of columns in the receiver, enough columns are created to expand the receiver to be column columns wide.

Discussion

New cells are created if needed with makeCellAtRow:column:. This method redraws the receiver. Your code may need to send sizeToCells after sending this method to resize the receiver to fit the newly added cells.

If the number of rows or columns in the receiver has been changed with renewRows:columns:, new cells are created only if they’re needed. This fact allows you to grow and shrink an NSMatrix without repeatedly creating and freeing the cells.
