Both ENTER shortcut and TextArea in Vaadin

TextField f = new TextField();
Button b = new Button("Save");
b.setClickShortcut(KeyCode.ENTER); // For quick saving from text field itself

TextArea longText = new TextArea(); // "Enter" is garbled here

Hot to make the shortcut to work only in the from text field?

Solution

  • Use focus and blur listeners to remove and add the shortcut key:

        f.addFocusListener(new FocusListener() {
        @Override
        public void focus(FocusEvent event) {
            b.setClickShortcut(KeyCode.ENTER);
        }
    });
    f.addBlurListener(new BlurListener() {
        @Override
        public void blur(BlurEvent event) {
            b.removeClickShortcut();
        }
    });
