hi all

i have a jTextField and a jButton im my programm. i want to make the jButton
disable, when the jTextField is empty. the codes are follows:
void jTextField2_keyPressed(KeyEvent e) {
  if ( jTextField2.getText().equals( "" ) )
    jButton1.setEnabled( false );
  else
    jButton1.setEnabled( true );
}

but when i have inputed a charactor in the jTextField, the jButton is still
unusable, until i have inputed the second charator. how can i make it just
like i have hoped?

regrads
