Question

因此在这个应用程序中, 用户会点击一个按钮, 然后按钮会启动一个程序。这个按钮将拥有应用程序和图标的标题。我只需要知道如何获得图标, 比如 : < a href=\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\

所以我想知道的是:

Is there any REAL way to do this in Java
If so, how would you do it?

提前感谢!

Answer 1

您是否必须获得应用程序执行文件的图标? 如果在 java 中是可能的, 请查看 < a href=" http://www. rgagnon.com/javadetails/java-0 439. html" rel= “ noreferrer” > 此教程 < /a >, 解释从 Java 应用程序中从可执行的二进制文件提取应用程序图标的几种方法。

看看这个代码:

String s = "c:/windows/regedit.exe";
File file = new File(s);

// Get metadata and create an icon
sun.awt.shell.ShellFolder sf =
        sun.awt.shell.ShellFolder.getShellFolder(file);
Icon icon = new ImageIcon(sf.getIcon(true));

Answer 2

您可以简单地为此使用文件系统视图 :

public static void main(String[] args) {
    Icon icon = FileSystemView.getFileSystemView()
         .getSystemIcon(new File("C:\Windows\regedit.exe"));
    JFrame frame = new JFrame();
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.add(new JLabel(icon));
    frame.pack();
    frame.setVisible(true);
}
