Resizing Images in JPanel??
Ok I have this Bean machine game that I edited. One problem I have encountered...when I resize the frame, the picture/game does not resize. I have tried the repaint() method, but am I doing it wrong? Here is the code, any help is greatly appreciated.
Code:
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class Exercise14_24 extends JFrame {
private BeanMachinePanel paintPanel = new BeanMachinePanel();
public Exercise14_24() {
add(paintPanel);
}
static class BeanMachinePanel extends JPanel {
final static int HGAP = 20;
final static int VGAP = 20;
final static int RADIUS = 5;
final static int LENGTH_OF_SLOTS = 40;
final static int LENGTH_OF_OPENNING = 15;
final static int Y_FOR_FIRST_NAIL = 50;
final static int NUMBER_OF_SLOTS = 9;
final static int NUMBER_OF_ROWS = NUMBER_OF_SLOTS - 2;
public BeanMachinePanel() {
}
/** Paint message */
public void paintComponent(Graphics g) {
super.paintComponent(g);
int y = Y_FOR_FIRST_NAIL;
int xCenter = getWidth() / 2;
// Draw pegs in multiple lines
g.setColor(Color.GREEN);
for (int i = 0; i < NUMBER_OF_ROWS; i++) {
y += VGAP;
for (int k = 0; k <= i; k++) {
g.fillOval(xCenter - i * HGAP / 2 + k * HGAP - RADIUS, y - RADIUS, 2 * RADIUS, 2 * RADIUS);
}
}
// Draw vertical lines for slots
g.setColor(Color.BLACK);
y = y + RADIUS;
for (int i = 0; i < NUMBER_OF_SLOTS; i++) {
int x = xCenter - (NUMBER_OF_ROWS - 1) * HGAP / 2 + (i - 1) * HGAP;
g.drawLine(x, y, x, y + LENGTH_OF_SLOTS);
}
// Draw a horizontal line for bottom
g.drawLine(xCenter - (NUMBER_OF_ROWS - 1) * HGAP / 2 - HGAP, y + LENGTH_OF_SLOTS,
xCenter - (NUMBER_OF_ROWS - 1) * HGAP / 2 + NUMBER_OF_ROWS * HGAP, y + LENGTH_OF_SLOTS);
// Draw two side lines
g.drawLine(xCenter + HGAP / 2, Y_FOR_FIRST_NAIL + RADIUS, xCenter - (NUMBER_OF_ROWS - 1) * HGAP / 2 + NUMBER_OF_ROWS * HGAP, y);
g.drawLine(xCenter - HGAP / 2, Y_FOR_FIRST_NAIL + RADIUS, xCenter - (NUMBER_OF_ROWS - 1) * HGAP / 2 - HGAP, y);
// Draw two vertical lines for the openning
g.drawLine(xCenter - HGAP / 2, Y_FOR_FIRST_NAIL + RADIUS, xCenter - HGAP / 2, Y_FOR_FIRST_NAIL - LENGTH_OF_OPENNING);
g.drawLine(xCenter + HGAP / 2, Y_FOR_FIRST_NAIL + RADIUS, xCenter + HGAP / 2, Y_FOR_FIRST_NAIL - LENGTH_OF_OPENNING);
}
}
public static void main(String[] args) {
JFrame frame = new Exercise14_24();
frame.setTitle("BEAN MACHINE");
frame.setSize(300, 300);
frame.setLocationRelativeTo(null);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setVisible(true);
}
}
