Method Detail

• popup

  public void popup()

  Popup a context menu. Use this when you create a Menu that will be used for the popup context menu in response to a right-click somewhere. The menu will appear where the mouse pointer is.

  Unlike normal Menus that are part of an application's MenuBar, context menus are not mapped automatically, so you need to have showAll() called on them once you're done building them to allocate their resources (otherwise you end up with a 1x1 pixel sized menu with nothing in it).

• popup

  public void popup(int x,
           int y)

  Having constructed a Menu to be used as the context menu, present it at the specified location. This is useful in conjunction with TextView's getLocation() if you wish to place the menu at the "cursor position" rather than where the mouse pointer is.

  4.0.15

• popup

  public void popup(StatusIcon status)

  A special case for popping up the context menu associated with a StatusIcon. Having constructed a Menu to be used as the context menu, you then call this from the StatusIcon.PopupMenu signal callback as follows:

   StatusIcon si;
   Menu context;
   ...
   
   si.connect(new StatusIcon.PopupMenu() {
       public void onPopupMenu(StatusIcon source, int button, int activateTime) {
           context.popup(source);
       }
   });
   

  Don't forget to call showAll() on the Menu when you're done constructing it before trying to use it the first time.

  4.0.3

• setAcceleratorGroup

  public void setAcceleratorGroup(AcceleratorGroup group)

  This method must be called in order to have the key bindings in MenuItems work. It has to be the same AcceleratorGroup that was specified for the enclosing top level Window that this Menu will be a part of via Window's addAcceleratorGroup().

  Since:

  4.0.16
