    Default Some much needed help, and questions.

    How would I prevent a JPane from resizing? I've tried Pane.setPreferred/.setMin and .setMax and neither work. Or am I doing something wrong?

    Also my problem with the filechooser is it is smushed in 3,1 is there a way I can get it fully into 3,1?

     JFrame prog = new JFrame("Chris's file synchronization");
     
            GridLayout topPanel = new GridLayout(4,1);
            prog.setLayout(topPanel);  
     
            JPanel P1 = new JPanel();                
            P1.add(targetLabel, FlowLayout.LEFT); 
            prog.add(P1);  
     
            P1.add(textField, FlowLayout.CENTER);    
            prog.add(P1);       
            textField.setPreferredSize(new Dimension(200,30));
     
            P1.add(browseButton, FlowLayout.RIGHT);  
            prog.add(P1);       
     
            JPanel P2 = new JPanel();                    
            P2.add(sourceLabel, FlowLayout.LEFT);    
            prog.add(P2);    
     
            P2.add(textField1, FlowLayout.CENTER);
            textField1.setPreferredSize(new Dimension(200,30));
            prog.add(P2);
     
            P2.add(browseButton1, FlowLayout.RIGHT);
            prog.add(P2);

    in the code above you are adding Panel p1 and Panel p2 two times in the frame , which is not possible , one object cannot be available at two places .

    So add components into the panel you want to add and then one time add that panel into frame.
    Thanks and Regards
