All Implemented Interfaces:

ActionListener, MouseListener, Serializable, EventListener, CellEditor, TableCellEditor, TableCellRenderer

public class ButtonCellRenderer
extends AbstractCellEditor
implements TableCellRenderer, TableCellEditor, ActionListener, MouseListener

The ButtonCellRenderer class provides a renderer and an editor that looks like a JButton. The renderer and editor will then be used for a specified column in the table. The TableModel will contain the String to be displayed on the button.

The button can be invoked by a mouse click or by pressing the space bar when the cell has focus. Optionally a mnemonic can be set to invoke the button. When the button is invoked the provided Action is invoked. The source of the Action will be the table. The action command will contain the model row number of the button that was clicked.
