  • .gwt-PasswordTextBox-readonly { dependent style set when the password text box is read-only }

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();

    // TODO(ECC) must be tested.
    tb.addKeyPressHandler(new KeyPressHandler() {

      public void onKeyPress(KeyPressEvent event) {
        if (!Character.isDigit(event.getCharCode())) {
          ((TextBox) event.getSource()).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);
  }
}
