public class JPopupMenu
extends JComponent
implements Accessible, MenuElement
```
An implementation of a popup menu -- a small window that pops up and displays a series of choices. A JPopupMenu is used for the menu that appears when the user selects an item on the menu bar. It is also used for "pull-right" menu that appears when the selects a menu item that activates it. Finally, a JPopupMenu can also be used anywhere else you want a menu to appear. For example, when the user right-clicks in a specified area.
For information and examples of using popup menus, see How to Use Menus in The Java Tutorial.
Warning: Swing is not thread safe. For more information see Swing's Threading Policy.
Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans^TM has been added to the java.beans package. Please see XMLEncoder.

  - processFocusEvent
```
protected void processFocusEvent(FocusEvent evt)
```
    Description copied from class: Component
    Processes focus events occurring on this component by dispatching them to any registered FocusListener objects.
    This method is not called unless focus events are enabled for this component. Focus events are enabled when one of the following occurs:
    - A FocusListener object is registered via addFocusListener.
    - Focus events are enabled via enableEvents.
    If focus events are enabled for a Component, the current KeyboardFocusManager determines whether or not a focus event should be dispatched to registered FocusListener objects. If the events are to be dispatched, the KeyboardFocusManager calls the Component's dispatchEvent method, which results in a call to the Component's processFocusEvent method.
    If focus events are enabled for a Component, calling the Component's dispatchEvent method with a FocusEvent as the argument will result in a call to the Component's processFocusEvent method regardless of the current KeyboardFocusManager.
    
    Note that if the event parameter is null the behavior is unspecified and may result in an exception.
    Overrides:
    
    processFocusEvent in class Component
    
    Parameters:
    evt - the focus event
    See Also:
    FocusEvent, FocusListener, KeyboardFocusManager, Component.addFocusListener(java.awt.event.FocusListener), Component.enableEvents(long), Component.dispatchEvent(java.awt.AWTEvent)

```
    Processes key stroke events such as mnemonics and accelerators.
    
    Overrides:

    Parameters:
    evt - the key event to be processed

  - setLightWeightPopupEnabled
```
public void setLightWeightPopupEnabled(boolean aFlag)
```
    Sets the value of the lightWeightPopupEnabled property, which by default is true. By default, when a look and feel displays a popup, it can choose to use a lightweight (all-Java) popup. Lightweight popup windows are more efficient than heavyweight (native peer) windows, but lightweight and heavyweight components do not mix well in a GUI. If your application mixes lightweight and heavyweight components, you should disable lightweight popups. Some look and feels might always use heavyweight popups, no matter what the value of this property.
    
    Parameters:
    aFlag - false to disable lightweight popups
