    Default Help w/ hw , help with panels layouts in frame.

    It is a class assignment, I have to create a form as given in a picture but I was not given any instructions ...
    Now they did say the window is splited to 3 forms.
    I am not sure what to do I think they meant panels? (by saying forms)...

    this is the pic:
    class_hw.jpg

    My program is different, I don;t know what to do witht he middle panel, I used grid and it's even on the columns unlike the example I tried using different layouts but for no use

    Now I have no idea what this gray line in between the panels is...

    Please help me figure this out.

    This is my code:
    import java.awt.BorderLayout;
    import java.awt.Color;
    import java.awt.Font;
    import java.awt.GridLayout;
     
    import javax.swing.JComponent;
    import javax.swing.JFrame;
    import javax.swing.JLabel;
    import javax.swing.JPanel;
    import javax.swing.JTextField;
    import javax.swing.SwingConstants;
    import javax.swing.border.Border;
    import javax.swing.border.LineBorder;
    import javax.swing.border.TitledBorder;
     
     
    public class HW2_ShirFriedman {
     
    	/**
    	 * @param args
    	 */
    	public static void main(String[] args) {
    		new ApplicationForm();				
    	}
     
    }
     
    class ApplicationForm
    {
    	ApplicationForm()
    	{
    		boolean aln=false;		
    	//declaring the frame
    		JFrame frame = new JFrame("Aplication Form");
     
     
    		//frame settings

    		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    		frame.setLocationRelativeTo(null); // Center the frame
    		frame.setAlwaysOnTop(true);
    		//frame.pack();
    		frame.setVisible(true);
    		frame.setLayout(new BorderLayout());

    		//center panel				
    		JPanel List_of_references=new JPanel(new GridLayout(5,2));
     
    		List_of_references.setBorder(new TitledBorder("List of references"));		
    		aln=true;
     
     
    		List_of_references.add(createLabel("*1: ",Color.RED,null,aln));

    		Programming_Languages.add(createLabel("",null,b,aln));		
    		Programming_Languages.add(createLabel("",null,b,aln));
     
    		//attaching the center panel to the frame
     
    		frame.add(BorderLayout.SOUTH,Programming_Languages);
     
    	}
     
     
    	private JLabel createLabel(String label_name,Color c,Border b,boolean setalighright)
    	{
    		JLabel label=new JLabel(label_name);
    		if(setalighright)
    			label.setHorizontalAlignment(SwingConstants.RIGHT);	
    		else
    			label.setHorizontalAlignment(SwingConstants.CENTER);
     
    		label.setForeground(c);
    		label.setBorder(b);
    		Font myFont = new Font("Times New Roman", Font.ITALIC, 15);
     
    		label.setFont(myFont);
    		return label;
    	}
    }


    looks like this:

    PS:Sorry it turned out really small I hope u can see the difference in the middle panel and the green lines I am missing in my code but present in the example.

    Have you considered using GridBagLayout, not GridLayout for the middle JPanel?

    I can try though we only learned grid flow and border in class.
    Though I don;t mind trying (which I will do right away) it still leaves the question how the gray line in between the panels is created.
    Since it adds to the width between the panels it does not seem to be a part of the panels I don't see a way to add it to the frame though.

    edit: after reading a bit about gridbag : gridbag seems complicated (in comparison to the basic 3 I pointed) since we didn't even mention its existance I hardly believe they expect us to use it.

    The lines may be created by borders, but it's hard to tell as your images are so small.

    I hope this is better
    They did split to 3 parts (using the word forms) but it could b anything I guess like parts in parts or w/e they did not say what not to use :S...
    -.- I am clueless....I tried compound border but I don;t need to touch the sides only upper and lower part of the middle panel.
    And yet again the middle panel's layout is wrong I can;t seem to fix it.

    Left column should start to the most left and go through the center while the right column should start at the end of the center and till the end of the right part.

    can;t make it happen (I can let it start from the center and go to the right, alright, but not from the left -.-)
