图片不会出现在JLabel中 [英] Image won't appear in JLabel

问题描述

我已经使用Netbeans的GUI Builder为我的应用程序创建了GUI.我试图显示包含JLabel和图像的JFrame，但无法显示Image.

I've created GUI for my application using Netbeans' GUI Builder. I am trying to display a JFrame containing a JLabel with an image, and I can't get the Image to display.

我生成的代码:

private void initComponents() {
        //...
        jLabel1 = new JLabel(new ImageIcon(myPicture));
}

我的班级代码:

public class GUIWindow extends javax.swing.JFrame {

    BufferedImage myPicture;

    /** Creates new form GUIWindow */
    public GUIWindow() throws IOException {
        myPicture = ImageIO.read(new File("images/logo.png"));
        initComponents();
        this.add(jLabel1);

    }
}

但是我仍然看不到图像... (图像文件的路径很好)诸如此类:

but I still don't see an image ... (path to the image file is fine) its sth like:

my-project :
  /build
  /dist
  /images/logo.png
  /nbproject
  /src (here I have all my source files)
  /build.xml
  /manifest.mf

推荐答案

您可以这样使用

URL imgSmartURL = this.getClass().getResource("your image path");
jLabel1 = new JLabel(new ImageIcon(imgSmartURL), JLabel.CENTER);
