    <p>I made the variables for borderX1-Y2 at the top but I didn't assign them til the paint method. I checked the values inside the method and they are correct, but when I checked them in another method they are 0. How do I get them to keep their values?</p> <pre><code>public void paint(Graphics g) { borderX1 = 20; borderY1 = 20; borderX2 = getWidth(); borderY2 = getHeight(); g.setColor(Color.white); g.fillRect(0, 0, borderX2, borderY2); g.setColor(Color.blue); g.drawRect(borderX1, borderY1, borderX2 - 40, borderY2 - 40); } </code></pre> <p>heres everything else (I cut the unnecessary bits)</p> <pre><code>public class ShapePanel extends JPanel { private int borderX1; private int borderY1; private int borderX2; private int borderY2; public ShapePanel(){} public void paint(Graphics g) { borderX1 = 20; borderY1 = 20; borderX2 = getWidth(); borderY2 = getHeight(); g.setColor(Color.white); g.fillRect(0, 0, borderX2, borderY2); g.setColor(Color.blue); g.drawRect(borderX1, borderY1, borderX2 - 40, borderY2 - 40); } public int getX1() {return borderX1;} public int getY1() {return borderY1;} public int getX2() {return borderX2;} public int getY2() {return borderY2;} } </code></pre> <p>My error is in my returns, they return a value of 0 for all of them</p> <p>I can initialize the variables like this</p> <pre><code>private int borderX1 = 20; private int borderY1 = 20; private int borderX2 = 762; private int borderY2 = 533; </code></pre> <p>but I want the values of X2 and Y2 to change based on the window size</p>

    1. COWhat are the types - int/double ? I guess the method you are calling is before the paint() call is made .

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.
