ComponentHandlerNew

public ComponentHandlerNew(com.klg.jclass.table.JCTable table)

Creates new ComponentHandler instance linked to table.

Parameters:

table - The table for this component handler

Method Detail

addListeners

protected void addListeners(Component c,
                            KeyListener keyListener,
                            FocusListener focusListener)

Specified by:

addListeners in class ComponentHandler

Parameters:

c - The component to which to add the listeners

keyListener - The key listener to add

focusListener - The focusListener to add

focusGained

public void focusGained(FocusEvent event)

Specified by:

focusGained in class ComponentHandler

Parameters:

event - The focus event which caused foucs to be gained.

focusLost

public void focusLost(FocusEvent event)

Removes TraverseHandler as a key listener on the component when it loses focus.

Specified by:

focusLost in interface FocusListener

Specified by:

focusLost in class ComponentHandler

Parameters:

event - The focus event which caused foucs to be lost.

keyPressed

public void keyPressed(KeyEvent event)

Tracks TAB/SHIFT-TAB and keypad arrow keys to control navigation when a component has focus.

Specified by:

keyPressed in interface KeyListener

Specified by:

keyPressed in class ComponentHandler

Parameters:

event - The event from the key press
