why is this not adding both instances of the move class. it only adds the last one called. the class paint is below what should i change in order for it paint both instances of move
package puzzle;
import java.awt.*;
import java.awt.geom.*;
import javax.swing.*;
public class Move extends JPanel{
int x;
int y;
Color kk;
public Move(int x1, int y1, Color k)
{
x=x1;
y=y1;
kk = k;
}
public void paintComponent(Graphics g)
{Graphics2D g2 = (Graphics2D)g;
super.paintComponent(g2);
g2.setColor(kk);
g2.fill(new RoundRectangle2D.Float(x, y, 50, 50,10,10));
g2.drawString(x+", "+y, 200, 200);
}
}
the class move paints a rectangle with the position and color passed from the puzzle class
Are you taking layout managers into consideration? Do you know about JFrame’s contentPane using BorderLayout as its default layout manager, and if you add components to this without constants, they are added BorderLayout.CENTER, and only one of these can be visible at a time (the last added).
I think that you might do better disassociating Move from JPanel, yes making it paintable, but making it more of a logical object rather than a gui component and instead of having it extend JPanel, allow a single drawing JPanel to hold one or more Move objects and then draw the Move objects in this JPanel’s paintComponent method.
Also, you seem to be using several java.util.Timers in your code, but since it is a Swing application, it would likely be better served by using javax.swing.Timers instead, in fact perhaps just one Swing Timer that functioned as a game loop.
