I'm trying to make it when you click the cameraButton
, the graphics show, but when clicked again, it closes.
@Override
public void paintComponent(Graphics g) {
super.paintComponent(g);
int camButtonWidth = 500;
int camButtonHeight = 33;
int camButtonX = (width - camButtonWidth) / 2;
int camButtonY = (height - camButtonHeight) - 5;
int camWidth = width - 50;
int camHeight = (height - (camButtonHeight * 2)) - 10;
int camX = (width - camWidth) / 2;
int camY = ((height - camHeight) - camButtonHeight) / 2;
Graphics2D g1 = (Graphics2D) g;
Graphics2D g2 = (Graphics2D) g;
Graphics2D g3 = (Graphics2D) g;
RoundRectangle2D camButton = new RoundRectangle2D.Double(camButtonX, camButtonY, camButtonWidth, camButtonHeight, 25, 25);
RoundRectangle2D cameras = new RoundRectangle2D.Double(camX, camY, camWidth, camHeight, 25, 25);
// Background
g1.setColor(Color.BLACK);
g1.fillRect(0, 0, width, height);
addMouseListener(new MouseListener() {
@Override
public void mouseClicked(MouseEvent e) {
if (camButton.contains(e.getPoint())) {
camUp = !camUp;
repaint();
}
}
@Override
public void mousePressed(MouseEvent e) {
}
@Override
public void mouseReleased(MouseEvent e) {
}
@Override
public void mouseEntered(MouseEvent e) {
}
@Override
public void mouseExited(MouseEvent e) {
}
});
// Camera Button
g2.setColor(camColor);
g2.fill(camButton);
paintCameras = camUp;
// Cameras
g3.setColor(camColor);
if (paintCameras) {
g3.fill(cameras);
}
repaint();
}
Try to change make it when you click the camera button, a graphics object shows, but when clicked again, it closes.
To get this sort of program to work you should:
camUp = !camUp;
as you're doingrepaint()
within a painting method as that will cause an uncontrolled animation. If you need a Swing animation, then use a Swing Timer so that you can fully control it. I don't see the need for it here.For example:
import java.awt.*;
import java.awt.event.*;
import java.awt.geom.*;
import java.awt.image.BufferedImage;
import javax.swing.*;
