Making a Java panel fullscreen
提问by clamp
How would you make a JComponent(panel, frame, window, etc.) fullscreen, so that it also overlaps everything on the screen including the windows start bar?
您将如何制作JComponent（面板、框架、窗口等）全屏，以便它也覆盖屏幕上的所有内容，包括窗口开始栏？
I don't want to change the resolution or anything with the graphics device like bitdepth etc, I just want to overlap everything else.
我不想更改分辨率或任何图形设备（如位深度等），我只想重叠其他所有内容。

You can try some of the codes in this page, allowing a container to fill the screen (so it is not a solution for an individualcomponent, but for a set of components within a container like a JFrame)
你可以试试这个页面中的一些代码，允许一个容器填满屏幕（所以它不是针对单个组件的解决方案，而是针对一个容器内的一组组件，比如一个JFrame）
public class MainWindow extends JFrame
{
public MainWindow()
{
super("Fullscreen");
getContentPane().setPreferredSize( Toolkit.getDefaultToolkit().getScreenSize());
pack();
setResizable(false);
show();
SwingUtilities.invokeLater(new Runnable() {
public void run()
{
Point p = new Point(0, 0);
SwingUtilities.convertPointToScreen(p, getContentPane());
Point l = getLocation();
l.x -= p.x;
l.y -= p.y;
setLocation(l);
}
});
}
...
}

You need to use the following API: http://java.sun.com/docs/books/tutorial/extra/fullscreen/index.html
您需要使用以下 API：http: //java.sun.com/docs/books/tutorial/extra/fullscreen/index.html
Going full screen isn't as simple as making a large panel, you need to look into the underlying OS graphics. But your JPanel code should translate just fine.
全屏并不像制作大面板那么简单，您需要查看底层的操作系统图形。但是您的 JPanel 代码应该可以很好地翻译。

Check out this tutorialdescribing Java's Full-Screen mode API.
查看本教程描述 Java 的全屏模式 API。
Example code (taken from the tutorial). Note that the code operates on a Windowso you would need to embed your JPanelwith a Window(e.g. JFrame) in order to do this.
示例代码（取自教程）。请注意，代码在 a 上运行，Window因此您需要JPanel使用 a Window(例如JFrame)嵌入您的代码才能执行此操作。
GraphicsDevice myDevice;
Window myWindow;
try {
myDevice.setFullScreenWindow(myWindow);
...
} finally {
myDevice.setFullScreenWindow(null);
}

I needed to search a lot, to do the same. Here is completely a working version of it by steps, so that i can find it later also, and use it.
我需要搜索很多，做同样的事情。这是它的完整工作版本，按步骤进行，以便我以后也可以找到它并使用它。
Step 1: create a file called fullscreen.java
第 1 步：创建一个名为 fullscreen.java 的文件
Step 2: copy this code and paste it as it is:
第 2 步：复制此代码并按原样粘贴：
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class fullscreen extends Window
{
private Button button;
public fullscreen()
{
super(new Frame());
button = new Button("Close");
button.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent e)
{
System.exit(0);
}
});
setLayout(new FlowLayout());
add(button);
Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
setBounds(0,0,screenSize.width, screenSize.height);
}
public static void main(String[] args)
{
// This will take over your whole screen tested and works in my:
// Fedora 12/13/14
// CentOS 5.0
// if this works for you, in other platforms, please leave a comments which OS it worked.
// happy coding!
new fullscreen().setVisible(true);
}
}
Step 3: compile the code and run
第三步：编译代码并运行
Done.
完毕。

If I were you I would try to make Java not draw the border of the Jframe, then make it take all the screen.
如果我是你，我会尝试让 Java 不绘制 Jframe 的边框，然后让它占据整个屏幕。
import java.awt.GraphicsEnvironment;
import java.awt.Rectangle;
import javax.swing.JFrame;
public class FenNoBorder extends JFrame {
public FenNoBorder () {
setUndecorated(true);
setVisible(true);
GraphicsEnvironment graphicsEnvironment=GraphicsEnvironment.getLocalGraphicsEnvironment();
Rectangle maximumWindowBounds=graphicsEnvironment.getMaximumWindowBounds();
setBounds(maximumWindowBounds);
}
}
