Question

I have a JFrame with 1 panel for drawing and set KyeListener for JFrame. It works fine unless I add JTextArea or JTextPane. Looks like it stops responding at all. I need some option to display the text and use keylistener for animation. I don’t need anything to type, I just want my keylistener working all the time. I need something better than JLabel, I want some formatting.

Answer 1

1. KeyListener isn’t designated for listening KeyEvents came from keyboard to the Swing GUI,

2. because KeyListener required focusable JComponent, you have to set for setFocusable() or programatically moving with Focus

3. Focus / Focus SubSystem is asynchonous

4. use KeyBindings rather that bothering with Focus / Focus SubSystem
