Just getting into building GUI's with the NetBeans 5 GUI builder and encountered an issue that has stopped me dead in my tracks...
Everything was going smooth...
A short discription of the interface:
1 JFrame
3 JPanel (setupPanel, dataPanel, gameSheet)
and a bunch of buttons, text feilds and all that jazz (I removed most of them though so that I can focus on my issue)
The issue:
I would like to draw to the JPanel named gameSheet...nothing too fancy...just some Rectangles.
I have been able to draw to a single JPanel writing the code from scratch, but have no idea what to do with all this code that has been generated for me..
The answer is right in front of me, I just can see it...
Can someone show me how to draw to a JPanel(gameSheet) using the following code?
Any help would be greatly appreciated. This is starting to drive me nuts.
Code:
package my.hanoi;
import java.awt.Color;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.Rectangle;
import javax.swing.JLabel;
import javax.swing.JPanel;
public class hanoiWin extends javax.swing.JFrame {
/** Creates new form hanoiWin */
public hanoiWin() {
initComponents();
//gameSheet.setBackground(Color.blue);
}
