Method Detail

createUI

public static ComponentUI createUI(JComponent x)

Description copied from class: ComponentUI

Returns an instance of the UI delegate for the specified component. Each subclass must provide its own static createUI method that returns an instance of that UI delegate subclass. If the UI delegate subclass is stateless, it may return an instance that is shared by multiple components. If the UI delegate is stateful, then it should return a new instance per component. The default implementation of this method throws an error, as it should never be invoked.

installDefaults

protected void installDefaults()

getPropertyPrefix

protected String getPropertyPrefix()

createMouseInputListener

createMenuDragMouseListener

createMenuKeyListener

protected MenuKeyListener createMenuKeyListener(JComponent c)

Overrides:

createMenuKeyListener in class BasicMenuItemUI

getMaximumSize

public Dimension getMaximumSize(JComponent c)

Description copied from class: ComponentUI

Returns the specified component's maximum size appropriate for the look and feel. If null is returned, the maximum size will be calculated by the component's layout manager instead (this is the preferred approach for any component with a specific layout manager installed). The default implementation of this method invokes getPreferredSize and returns that value.

Overrides:

getMaximumSize in class BasicMenuItemUI

Parameters:

c - the component whose maximum size is being queried; this argument is often ignored, but might be used if the UI object is stateless and shared by multiple components

Returns:

a Dimension object or null
