18.58 java.awt.TextComponent (JDK 1.0)

This class is the superclass of the TextArea and TextField components. It cannot be instantiated itself, but provides methods that are common to these two component types. setEditable() specifies whether the text in the text component is editable or not. getText() returns the text in the component, and setText() specifies text to be displayed. getSelectedText() returns the currently selected text in the text component, and getSelectionStart() and getSelectionEnd() return the extents of the selected region of text. select() and selectAll() select some or all of the text displayed in the text component.

See also TextField and TextArea.
