Method Detail

createKeyListener

protected java.awt.event.KeyListener createKeyListener()

Creates the key listener for handling keyboard navigation in the JSmartGrid.

createFocusListener

protected java.awt.event.FocusListener createFocusListener()

installUI

public void installUI(javax.swing.JComponent jc)

Overrides:

installUI in class javax.swing.plaf.ComponentUI

installDefaults

protected void installDefaults()

Initialize Grid properties, e.g. font, foreground, and background. The font, foreground, and background properties are only set if their current value is either null or a UIResource, other properties are set if the current value is null.
