PopupMenu in Java Example

A popupmenu is a small window that pops up and displays a list of choices such as Cut, Copy, Paste, Select All etc. This menu is invisible until the user makes a platform specific mouse action such as pressing the right mouse button over a popup enabled component. The popup menu then appears under the cursor.

In order to create a pop up menu, java .awt .PopupMenu class is used. It is a subclass of Menu and is used very much like a Menu. It provides the following two constructors

• PopupMenu () – Creates an empty popup menu.

• PopupMenu (String title) – Creates an empty pop up menu with the as the title of the popup menu.

As expected, the AWT provides fairly complete support for creating applications using the menu bar (menu bar), drop down menus (pull-down menus) and  independent menu (pop-up menus) through set of classes briefly described following:

import java.awt.*; 
 class PopupMenuExample extends Frame 
 { 
      PopupMenu popupMenu; 
      public PopupMenuExample() 
     { 
            setLayout(new FlowLayout()); 
            popupMenu = new PopupMenu(); 
            popupMenu.add(new MenuItem("Cut")); 
            popupMenu.addSeparator(); 
            popupMenu.add(new MenuItem("Cut")); 
            popupMenu.addSeparator(); 
            popupMenu.add(new MenuItem("paste")); 
            add(popupMenu);    
            setTitle("PopupMenu in Java Example"); 
            setSize(300,120); 
            setVisible(true); 
            popupMenu.show(this,100,100); 
     } 
 } 
  class PopupMenuJavaExample 
  { 
         public static void main(String[] args) 
        { 
             PopupMenuExample frame = new PopupMenuExample(); 
        } 
  }
