Java, how can I popup a dialog box as only an image?
提问by vejmartin
I'm trying to find a way to replace all the contents of a JDialog to simply an image. It's for the about page of a project I'm working on and I want when the user clicks on the About section, an image to popup in the style of a JDialog(and to disappear when focus is lost). Example: http://www.tecmint.com/wp-content/uploads/2012/08/About-Skype.jpgThere Skype displays only an image they've created as their "About" page. How can I make an "image dialog" in Java(swing)?
我试图找到一种方法将 JDialog 的所有内容替换为简单的图像。它用于我正在处理的项目的关于页面，当用户单击“关于”部分时，我想要一个图像以 JDialog 的样式弹出（并且在失去焦点时消失）。示例：http: //www.tecmint.com/wp-content/uploads/2012/08/About-Skype.jpgSkype 仅显示他们创建的图像作为“关于”页面。如何在 Java(swing) 中制作“图像对话框”？

Use an undecorated JDialog with a JLabel containing an ImageIcon:
将未修饰的 JDialog 与包含 ImageIcon 的 JLabel 一起使用：
JDialog dialog = new JDialog();
dialog.setUndecorated(true);
JLabel label = new JLabel( new ImageIcon(...) );
dialog.add( label );
dialog.pack();
dialog.setVisible(true);

BufferedImage image = ImageIO.read(new File("myfile.png"));
JLabel picLabel = new JLabel(new ImageIcon(image));
JOptionPane.showMessageDialog(null, picLabel, "About", JOptionPane.PLAIN_MESSAGE, null);

Here you go, I have annotated the code for you
给你，我已经为你注释了代码
import javax.swing.JOptionPane; //imports
import javax.swing.JLabel;
import javax.swing.JFrame;
import javax.swing.ImageIcon;
import java.awt.Toolkit;
import java.awt.Dimension;
public class img{
public static void main(String[] args){
JFrame f = new JFrame(); //creates jframe f
Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize(); //this is your screen size
f.setUndecorated(true); //removes the surrounding border
ImageIcon image = new ImageIcon(diceGame.class.getResource("image.png")); //imports the image
JLabel lbl = new JLabel(image); //puts the image into a jlabel
f.getContentPane().add(lbl); //puts label inside the jframe
f.setSize(image.getIconWidth(), image.getIconHeight()); //gets h and w of image and sets jframe to the size
int x = (screenSize.width - f.getSize().width)/2; //These two lines are the dimensions
int y = (screenSize.height - f.getSize().height)/2;//of the center of the screen
f.setLocation(x, y); //sets the location of the jframe
f.setVisible(true); //makes the jframe visible
}
}
