column(for:)
Returns the column index for the specified view.
Declaration
func column(for view: NSView) -> IntParameters
- view:
The view for which to retrieve the column.
Return Value
The index of the column containing view in the tableColumns array. This method returns -1 if the view is not in the table view. This method may also return -1 if the row containing the view is being animated away, such as during the deletion of a row.
Discussion
This method is typically called in the action method of an NSButton (or NSControl) to find out what row (and column) the action should be performed on.
The implementation is O(n) where n is the number of visible rows, so this method should generally not be called within a loop.
