JTextField - A TextField Lightweight Component

Contents
Swinging Duke

This specification describes the JTextField class, which provides the Java AWT TextField class with added functionality using Swing architecture.

This API adds two new methods -- getColumnWidth() and getRowHeight() -- to the JTextField class. Also, two old methods -- getPreferredSize() and getMinimumSize() -- are no longer present because it has been determined that they should have protected or private access specifiers.

In the Swing version of the TextField class, the notion of a desired number of columns still exists for compatibility, but its meaning is more controllable. The width of a column is now defined by the getColumnWidth() method. By default, this method produces the character width of the letter m. It can be redefined to be a different value. For symmetry, the height of a row can be changed by redefining the getRowHeight() method. By default, this value is defined as the height of the current font.

The API

The JTextField API is generated by JavaDoc. It contains the bulk of the specification.
