noteNumberOfItemsChanged()
Informs the combo box that the number of items in its data source has changed.
Declaration
func noteNumberOfItemsChanged()Discussion
This method allows the combo box to update the scrollers in its displayed pop-up list without actually reloading data into the combo box. It is particularly useful for a data source that continually receives data in the background over a period of time, in which case the NSComboBoxCell can remain responsive to the user while the data is received.
See the NSComboBoxCellDataSource informal protocol specification for information on the messages an NSComboBoxCell sends to its data source.
