Example

public class TextBoxExample implements EntryPoint {

  public void onModuleLoad() {
    // Make some text boxes.  The password text box is identical to the text
    // box, except that the input is visually masked by the browser.
    PasswordTextBox ptb = new PasswordTextBox();
    TextBox tb = new TextBox();

    // Let's disallow non-numeric entry in the normal text box.
    tb.addKeyboardListener(new KeyboardListenerAdapter() {
      public void onKeyPress(Widget sender, char keyCode, int modifiers) {
        if ((!Character.isDigit(keyCode)) && (keyCode != (char) KEY_TAB)
            && (keyCode != (char) KEY_BACKSPACE)
            && (keyCode != (char) KEY_DELETE) && (keyCode != (char) KEY_ENTER) 
            && (keyCode != (char) KEY_HOME) && (keyCode != (char) KEY_END)
            && (keyCode != (char) KEY_LEFT) && (keyCode != (char) KEY_UP)
            && (keyCode != (char) KEY_RIGHT) && (keyCode != (char) KEY_DOWN)) {
          // TextBox.cancelKey() suppresses the current keyboard event.
          ((TextBox)sender).cancelKey();
        }
      }
    });

    // Let's make an 80x50 text area to go along with the other two.
    TextArea ta = new TextArea();
    ta.setCharacterWidth(80);
    ta.setVisibleLines(50);

    // Add them to the root panel.
    VerticalPanel panel = new VerticalPanel();
    panel.add(tb);
    panel.add(ptb);
    panel.add(ta);
    RootPanel.get().add(panel);
  }
}
