    <p>Here's my code in question:</p> <pre><code>import java.awt.Color; import java.awt.Graphics; import javax.swing.JPanel; import sun.java2d.loops.DrawRect; import java.awt.event.MouseListener; import java.awt.event.MouseEvent; public class Board extends JPanel implements MouseListener { //instance variables private int width; private int height; private Block topLeft; private Block topRight; private Block botLeft; private Block botRight; public Board() //constructor { width = 200; height = 200; topLeft=new Block(0,0,width/2-10,height/2-10,Color.RED); topRight=new Block(width/2,0,width/2-10,height/2-10,Color.GREEN); botLeft=new Block(0,height/2,width/2-10,height/2-10,Color.BLUE); botRight=new Block(width/2,height/2,width/2-10,height/2-10,Color.YELLOW); setBackground(Color.WHITE); setVisible(true); //start trapping for mouse clicks addMouseListener(this); } //initialization constructor public Board(int w, int h) //constructor { width = w; height = h; topLeft=new Block(0,0,width/2-10,height/2-10,Color.RED); topRight=new Block(width/2,0,width/2-10,height/2-10,Color.GREEN); botLeft=new Block(0,height/2,width/2-10,height/2-10,Color.BLUE); botRight=new Block(width/2,height/2,width/2-10,height/2-10,Color.YELLOW); setBackground(Color.WHITE); setVisible(true); //start trapping for mouse clicks addMouseListener(this); } public void update(Graphics window) { paint(window); } public void paintComponent(Graphics window) { super.paintComponent(window); topRight.draw(window); topLeft.draw(window); botRight.draw(window); botLeft.draw(window); } public void swapTopRowColors() { Color temp = topLeft.getColor(topRight); topRight.setColor(temp); repaint(); } public void swapBottomRowColors() { } public void swapLeftColumnColors() { } public void swapRightColumnColors() { } </code></pre> <p>How would I swap the colors of 2 of these "squares" using the <code>.getColor()</code> method? I'm thinking I'm on the right track to achieving it but haven't had to do something like this with colors before.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
