title: java setEnable(false) does not work
body: <p>When I press <code>JLabel</code>, I get a <code>mousePressed</code> event call in which I want to disable a <code>JButton</code>.  However, nothing happens.  Why is this?</p>
  
  <p>Here is the <code>JLabel</code> <code>mousePress</code> event handler:</p>
  
  <pre><code>public void mousePressed(MouseEvent e) {
      get_clickevent(false)
  }
  </code></pre>
  
  <p>Here is the function that get call on <code>mousePressed</code>:</p>
  
  <pre><code>public void get_clckevent(final boolean value){
  
      java.awt.EventQueue.invokeLater(new Runnable() {
  
          boolean valu = value;
  
          public void run() {
  
              if (valu == false) {                   
                  btnSave.setEnabled(false); //here is button that does not disable.
              }
          }
      });
  </code></pre>
