// pushButton.fs
// Created By: Tobin Isenberg
// Date: 11/06/2001
// Version: 1.0
//
// Purpose:
//    Utility to assist in building a dialog with multiple buttons
//    and a text window that can be written too.  This is just an
//    example.
//
// Required Changes:
//    none
//
// Notes 1:
//    This script should be included in
//
// Exposed functions:
//
// public var createDialog( String titleOfDialogWindow )
//
//    Overview:
//       Creates a dialog with the title of the dialog based on the contents
//       of titleOfDialogWindow.
//
//    Returns:
//       Will return a var that can be used to add text to the dialog at any
//       point after the dialog is created including after buttons are pressed.
//       Will attempt to return null if an error occurred.
//
//    Example:
//       var textHandle = createDialog( "My Window" );
//       textHandle.append( "Hello World" );
//
// public void addButton( String theButton , function FunctionName );
//
//    OverView:
//       Adds a button with the text of the button being the contents of
//       "theButton".  When the button is pressed, the function will be
//       called that is referenced by "FunctionName";
//
//     Returns:
//       n/a
//
//     Example:
//       function myFunction() { info( "hello world" ); }
//       addButton( "MyButton", myFunction );
//
// public void closeDialog()
//    Overview:
//       Closes the existing dialog
//
//    Returns:
//       n/a
//
//    Example:
//       createDialog( "Hello World" );
//       closeDialog();
//
//
// Implementing:
//	1) Copy pushButton.fs and pushButtonTest.fs to installDir/database/scripts
//	2) Right-Click on Administration/Server/Operation Definitions and choose
//		Create Operation
//	3) Use the following information...
//		Name: Push Button Test
//		Menu Text: Push Button Test
//		Context: Element or Alarm
//		Match By: name expression
//			next box: .*
//		Permission: View
//		Type: Client script
//		Operation: load( "pushButtonTest.fs" );
//
//  By performing the right-click, an example dialog will show up.
