我的应用程序中有一个JWindow,它出现在右上角。我已经将形状设置为RoundRectangle2D,但是JWindow的边界没有抗锯齿,因此看起来很糟糕。所以我的问题是,如何对JWindow进行反别名?我知道如何使用Graphics对形状进行反别名,但这对JWindow来说不起作用,是吗?无论如何,我如何对JWindow的边界进行反别名?
代码:
public class Selector实现接口{
//Variables
//Windows
static JWindow Frame = new JWindow();
static JWindow[] Label = new JWindow[100];
static Shape Shape;
static JWindow ExitWindow = new JWindow();
static JWindow MenuWindowHide = new JWindow();
public static void initialize() {
//Settings
Frame.setBounds(0,0,(int)Utility.getScreenRes().getWidth(),(int)Utility.getScreenRes().getHeight());
Frame.setOpacity(0.4f);
ExitWindow.setBounds((int) (Utility.getScreenRes().getWidth() - 40), 25,20,20);
ExitWindow.getContentPane().setBackground(Color.DARK_GRAY);
ExitWindow.setShape(new RoundRectangle2D.Double(0,0,20,20, 6, 6));
//Post settings
Frame.setVisible(true);
ExitWindow.setVisible(true);
}
}
答案 0 :(得分:0)
为此,我将展示如何使用任何消除锯齿的形状制作JFrame。
public class MainFrame extends JFrame
{
public MainFrame()
{
setUndecorated(true);
setBackground(new Color(0,255,0,0));
setSize(300, 300);
add(PaintingSurface); //Where PaintingSurface is JPanel with PaintPanel method below
setVisible(true);
}
然后添加一个与Frame大小相同的JPanel,并在其paint方法中使用以下方法绘制所需的shpae
public void PaintPanel(Graphics g,Shape PaintArea)
{
Graphics2D gg = (Graphics2D) g;
gg.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
gg.fill(PaintArea);
}
