Change the example code from the TextBox Javadoc API like this:
tb.addKeyboardListener(new KeyboardListenerAdapter() {
public void onKeyPress(Widget sender, char keyCode, int modifiers) {
if (Character.isDigit(keyCode)) return;
if ((keyCode == '.') // Add all your allowed characters here
|| (keyCode == '$')
|| (keyCode == '#')) return;
// TextBox.cancelKey() suppresses the current keyboard event.
((TextBox)sender).cancelKey();
}
}
});
this allows digits and '.', '$' and '#'
