Class

NSTextField

Text that the user can select or edit and that sends its action message to its target when the user presses the Return key.

Overview

The NSTextField class uses the NSTextFieldCell class to implement its user interface.

The parent class, NSControl, provides the methods for setting the values of the text field, such as stringValue and doubleValue. There are corresponding methods to retrieve values.
