//		Implementation for menu creation class IDR_MENU2
//
// WARNING: Do not modify this file.  This file is recreated each time its
//          associated .rct/.res file is sent through the Java Resource Wizard!
//
// This class is use to create a menu on a Frame object.  For addtional
// information on using Java Resource Wizard generated classes, refer to the
// Visual J++ 1.1 documention.
//
// 1) Import this class in the .java file for the Frame that will use it:
//
//      import IDR_MENU2;
//
// 2) Create an instance of this class in your Applet's 'main' member, and call
//    CreateMenu() through this object:
//
//      IDR_MENU2 menu = new IDR_MENU2 (frame);
//      menu.CreateMenu();
//
// 3) To process events generated from user action on the menu, implement
//    the 'handleEvent' member for your Frame:
//
//      public boolean handleEvent (Event evt)
//      {
//
//      }
