I got really strange results when tried to listen to KeyEvents from
JTextArea, JTextPane, etc. Actually the deal is that i didn't get any
result at all! I know 4 sure that an instance of KeyAdapter is
constructed, but none of its methods is called when i press a key.
Should i set a keymap? I think it's not necessary, since there must be a
default one. Then anyway how could i add an Action for KeyStroke? I
considered the following code to be appropriate 4 this purpose, but got
only NullPointerException.

    Action action = new sendButtonAdapter();

    Keymap keymap = typingArea.getKeymap();
    KeyStroke key = KeyStroke.getKeyStrokeForEvent(
      new KeyEvent(typingArea, KeyEvent.VK_ENTER, 0, 0,
KeyEvent.VK_ENTER));
    keymap.addActionForKeyStroke(key, action);

So, definitely i'm doing smth wrong (or not?). But WHAT??? Well, that
was my question. Hope u would give me a hint.

PS: Actually customized DefaultStyledDocument with overridden
insertString() method do this task pretty good. But i'm just SO curious!
Anyway the solution must be simple.
