title: Swing + LWJGL not rendering anything. Black Screen
body: <p>I'm doing a Gr 12 Project. the basic idea is to render a map texture that can be changed via the swing GUI.<br>
  I'm stuck at rendering using a Display that's .parented to a JFrame.
  Nothing is showing up and i cant figure it out. ive changed the backround color and the rendering color. heres some of the code:  </p>
  
  <pre><code>   public class DisplayWindow extends JFrame{
  
     public Canvas canvas = new Canvas();                           
     private JPanel westPanel=new JPanel();                         
     private List animalArr;                                       
     private List animalOptionsBoxArr;                                                              
     public JLabel optionsLabel=new JLabel();                       
     public JToggleButton animalIOToggle = new JToggleButton();     
     public JTextArea animalIOText = new JTextArea();               
  
     List renderableEntities= new ArrayList();                      
  
     //states modified by logic class that handle all swing listners 
     private boolean resizePending=false;  
     private boolean exitPending=false;   
  
     DisplayWindow(List animalArr)
     {
       super(); 
       this.animalArr=animalArr; //created from db in logic class
     }
     public void run()
     {
       startDisplay();   
     }
  
  
     public void startDisplay() 
     {  
        //Init GUI
  
        setupFrame();             //setup main Jframe
        setupMainPanels();        //setup main panels within JFrames borderLayout)
        setupContentPanels();     //setup the content panels within the main panel
  
        canvas.setSize(getDisplayWidth(), getDisplayHeight());     
        canvas.setFocusable(true);                                
        canvas.setIgnoreRepaint(true);                         
  
        this.add(canvas,BorderLayout.CENTER);

  <p>There is allot of code so I dearly hope the problem is in there. I tried to format it a bit. that will explain unused objects/references ext. this is the only code related to LWJGL. DisplayWindow is run as a new Runnable thread.<br>
  This is what the program looks like at the moment:

  <p>Why is nothing showing in the display?  </p>
