Instance Method

makeCellAtRow:column:

Creates a new cell at the location specified by the given row and column in the receiver.

Declaration

- (NSCell *)makeCellAtRow:(NSInteger)row column:(NSInteger)col;

Parameters

row

The row in which to create the new cell.

column

The column in which to create the new cell.

Return Value

The newly created cell.

Discussion

If the receiver has a prototype cell, it’s copied to create the new cell. If not, and if the receiver has a cell class set, it allocates and initializes (with init) an instance of that class. If the receiver hasn’t had either a prototype cell or a cell class set, NSMatrix creates an NSActionCell.

Your code should never invoke this method directly; it’s used by addRow and other methods when a cell must be created. It may be overridden to provide more specific initialization of cells.
