// Dialog3.java:
// Implementation for container control initialization class Dialog3
//
// 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 can be use to create controls within any container, however, the
// following describes how to use this class with an Applet. 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 Applet that will use it:
//
// import Dialog3;
//
// 2) Create an instance of this class in your Applet's 'init' member, and call
// CreateControls() through this object:
//
// Dialog3 ctrls = new Dialog3 (this);
// ctrls.CreateControls();
//
// 3) To process events generated from user action on these controls, implement
// the 'handleEvent' member for your applet:
//
// public boolean handleEvent (Event evt)
// {
//
// }
//
