Constructor Detail

public BasicMenuUI()

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()

Overrides:

installDefaults in class BasicMenuItemUI

getPropertyPrefix

protected String getPropertyPrefix()

Overrides:

installListeners

protected void installListeners()

getActionMap

ActionMap getActionMap()

The ActionMap for BasicMenUI can not be shared, this is subclassed to create a new one for each invocation.

Overrides:

getActionMap in class BasicMenuItemUI

createActionMap

ActionMap createActionMap()

Invoked to create the ActionMap.

Overrides:

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:

appendPath

private static void appendPath(MenuElement[] path,
                               MenuElement elem)
