 * \section Intro_sec 1. About this Example
 *
 * Rich Text Editor example demonstrates the usage of Rich Text Editor. Most of the features
 * are handled automatically when the dialog framework creates the editor. However,
 * some steps, such as inserting an image, setting the text input type, or showing
 * the scroller require the use of methods or classes.
 *
 *
 * \subsection Sub11 1.1 APIs demonstrated
 *
 * - CEikRichTextEditor
 * - CFbsBitmap
 * - TPictureHeader
 * - CPicture
 *
 * \subsection Sub12 1.2 Prerequisites
 *
 * Symbian C++ basics
 *
 * \subsection Sub13 1.3 Running this example
 *
 * Start the application. An editor opens.
 * Select any part of the text: press and hold the Edit key while moving the scroller key
 * to left or right. The selected text is highlighted.

 *
 * \section Design_sec 3. Design and Implementation
 *
 * CEikRichTextEditor is the main class used in this example, which is an edit
 * window that supports rich text, including embedded objects represented
 * either by icons or glass doors. CRTEContainer contains CEikRichTextEditor.
 * The basic features are handled by CEikRichTextEditor API.
 *
 * Another important class CMyPicture, which is used to insert the picture in
 * the editor window.This class contains the CFbsBitmap class, which is
 * reference to bitmap data.
 *
 * \subsection Sub31 3.1 Capabilities
 *
 * The program capabilities are defined in the RichTextEditor_S60_3rd_Ed.mmp file: CAPABILITY NONE
 *
 * \subsection Sub32 3.2 Features

 * which is implemented by user defined class CMyPicture, which handles the picture insertion in the editor.
 *
 * \subsection Sub33 3.3 MMP Files
 *
 * This example is compatible with following S60 platforms
 * - S60 3rd Edition
 * - S60 2nd Edition
 * - S60 1st Edition <br>
 *  <br>Hence provided with two MMP files.
 * - The MMP file for S60 1st Edition and S60 2nd Edition is: RichTextEditor.mmp
 * - The MMP file for S60 3rd Edition is: RichTextEditor_S60_3rd_Ed.mmp
