/**
 * 
 * This sample demonstrates how to use the RAPC preprocessor. The
 * PreprocessorDemoScreen contains a text field to allow a user to enter text.
 * The "Clear Field" menu item is used to clear the text field and is
 * automatically added to the PreprocessorDemoScreen when the text field is
 * added to the screen. If the device supports touch gestures, a swipe gesture
 * will also cause the text field to be cleared. To ensure that this application
 * is compatible with devices which do not include touch screen specific APIs,
 * the preprocessor will only compile the sections of code pertinent to the
 * touch screen API if the TOUCH_API tag is defined. Otherwise only the
 * "Clear Field" MenuItem will allow a user to clear the text field.
 * 
 * See the "readme.txt" file for details on how to use the preprocessor.
 * 
 * Note: The "//#preprocess" directive must be the first line (with no preceding
 * characters or whitespace) in all files requiring preprocessing.
 * 
 * Note: At least one tag must be defined for the preprocessor to engage. In
 * this demo the "PREPROCESSOR" tag will serve this purpose and should not be
 * removed.
 * 
 * To test the demo in JDE 4.7 or later: 1. Ensure the TOUCH_API tag is defined
 * as outlined in the "readme.txt" file. 2. Build the project and run the demo.
 * Note that both the swipe gesture and the "Clear Field" MenuItem may be used
 * to clear the text field. 3. Remove the TOUCH_API tag as outlined in the
 * "readme.txt" file. 4. Build the project and run the demo. Note that only the
 * "Clear Field" MenuItem is used to clear the text field.
 * 
 * To test the demo in JDE 4.6.x or earlier: 1. Ensure the TOUCH_API tag is
 * defined as outlined in the "readme.txt" file. 2. Build the project. Note that
 * the project does not build successfully beacause the TouchEvent and
 * TouchGesture classes are not supported in JDE 4.6.x and earlier. 3. Remove
 * the TOUCH_API tag as outlined in the "readme.txt" file. 4. Build the project.
 * Note that the demo builds successfully.
