    BasicComboPopup

      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™ 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)`

    - #### processKeyEvent

          protected void processKeyEvent(KeyEvent evt)

      Processes key stroke events such as mnemonics and accelerators.
      Overrides:
        `processKeyEvent` in class `JComponent`
      Parameters:
        `evt` - the key event to be processed
      See Also:
        `KeyEvent`, `KeyListener`, `KeyboardFocusManager`, `DefaultKeyboardFocusManager`, `Component.processEvent(java.awt.AWTEvent)`, `Component.dispatchEvent(java.awt.AWTEvent)`, `Component.addKeyListener(java.awt.event.KeyListener)`, `Component.enableEvents(long)`, `Component.isShowing()`

    - #### add

          public JMenuItem add(Action a)

        `IllegalArgumentException` - if the value of `pos` < 0, or if the value of `pos` is greater than the number of items
      See Also:
        `Container.add(java.awt.Component)`, `Container.invalidate()`, `Container.validate()`, `Container.getComponentCount()`

    - #### 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.
