J2ME Text Box Example

This application illustrates how to create the text box using TextBox class. The TextBox class is a Screen that allows the user to enter and edit text. A TextBox has a maximum size, which is the maximum number of characters that can be stored in the object at any time. The following are the methods used in class:

delete(int offset, int length)
getCaretPosition()
getChars(char[] data)
getConstraints()
getMaxSize()
getString()
insert(char[] data, int offset, int length, int position)
insert(String src, int position)
setChars(char[] data, int offset, int length)
setConstraints(int constraints)
setMaxSize(int maxSize)
setString(String text)
size()

These methods are accessible in your MIDlet. The application is as follows:

TextBoxMIDlet.java

import javax.microedition.midlet.*; import javax.microedition.lcdui.*; public class TextBoxMIDlet extends MIDlet{ private Display display; public TextBoxMIDlet() { display = Display.getDisplay(this); } public void startApp() { TextBox t = new TextBox("TextBox Example",
"Hello Sandeep Kumar Suman !", 256, 0); display.setCurrent(t); } public void pauseApp() {} public void destroyApp(boolean unconditional) {} }
