createPropertyChangeListener

protected PropertyChangeListener createPropertyChangeListener(JComponent c)

Description copied from class: BasicMenuItemUI

Creates a PropertyChangeListener which will be added to the menu item. If this method returns null then it will not be added to the menu item.

Overrides:

Returns:
an instance of a PropertyChangeListener or null

createMenuKeyListener

protected MenuKeyListener createMenuKeyListener(JComponent c)
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:
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
