我正在尝试对透明进行双重缓冲,JWindow
但似乎使用的技术无效(不同的循环值相互绘制)。
public final class Overlay extends JWindow {
public static final Color TRANSPARENT = new Color(0, true);
public static Font standardFont = null;
public static Overlay open() {
return new Overlay();
}
private Overlay() {
Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
setAlwaysOnTop(true);
setBounds(0, 0, screenSize.width, screenSize.height);
setBackground(TRANSPARENT);
}
@Override
public void paint(Graphics g) {
BufferedImage bufferedImage = new BufferedImage(getWidth(), getHeight(), BufferedImage.TYPE_4BYTE_ABGR);
Graphics2D g2d = bufferedImage.createGraphics();
paintUs(g2d);
Graphics2D g2dComponent = (Graphics2D) g;
g2dComponent.drawImage(bufferedImage, null, 0, 0);
}
private void paintUs(Graphics2D g) {
int height = 420;
int x = 20;
g.setColor(TRANSPARENT);
g.fillRect(0, 0, getWidth(), getHeight());
g.setFont(standardFont == null ? standardFont = g.getFont().deriveFont(17f) : standardFont);
for (Plugin plugin : Abendigo.plugins()) {
g.setColor(Abendigo.plugins().isEnabled(plugin) ? Color.GREEN : Color.RED);
g.drawString(plugin.toString(), x + 5, getHeight() - height);
height += 20;
}
height += 20;
g.setColor(Color.YELLOW);
g.drawString("Cycle: " + Abendigo.elapsed + "ms", x, getHeight() - height);
}
@Override
public void update(Graphics g) {
paint(g);
}
}
