Swing 是否支持 Windows 7 风格的文件选择器?

问题描述

我刚刚根据 ) 调出这个对话框.以下是对SWT的FileDialog snippet 使用打开而不是保存对话框.我知道这不完全是您要找的东西，但是您可以将它隔离到一个实用程序类中，并将 swt.jar 添加到您的类路径中以实现此功能.

import org.eclipse.swt.*;导入 org.eclipse.swt.widgets.*;公共类 SWTFileOpenSnippet {公共静态无效主(字符串 [] args){显示显示=新显示()；壳壳=新壳(显示)；//不显示外壳.//shell.open();FileDialog dialog = new FileDialog (shell, SWT.OPEN | SWT.MULTI);String [] filterNames = new String [] {"所有文件(*)"};String [] filterExtensions = new String [] {"*"};String filterPath = "c:\";dialog.setFilterNames(filterNames);dialog.setFilterExtensions(filterExtensions);dialog.setFilterPath(filterPath);dialog.open();System.out.println("所选文件:");String[] selectedFileNames = dialog.getFileNames();for(字符串文件名:selectedFileNames){System.out.println(" " + 文件名);}shell.close();而 (!shell.isDisposed ()) {if (!display.readAndDispatch()) display.sleep();}display.dispose();}}

I just added a standard "Open file" dialog to a small desktop app I'm writing, based on the JFileChooser entry of the Swing Tutorial. It's generating a window that looks like this:

but I would prefer to have a window that looks like this:

In other words, I want my file chooser to have Windows Vista/Windows 7's style, not Windows XP's. Is this possible in Swing? If so, how is it done? (For the purposes of this question, assume that the code will be running exclusively on Windows 7 computers.)

解决方案

It does not appear this is supported in Swing in Java 6.

Currently, the simplest way I can find to open this dialog is through SWT, not Swing. SWT's FileDialog (javadoc) brings up this dialog. The following is a modification of SWT's FileDialog snippet to use an open instead of save dialog. I know this isn't exactly what you're looking for, but you could isolate this to a utility class and add swt.jar to your classpath for this functionality.

import org.eclipse.swt.*;
import org.eclipse.swt.widgets.*;

public class SWTFileOpenSnippet {
    public static void main (String [] args) {
        Display display = new Display ();
        Shell shell = new Shell (display);
        // Don't show the shell.
        //shell.open ();
        FileDialog dialog = new FileDialog (shell, SWT.OPEN | SWT.MULTI);
        String [] filterNames = new String [] {"All Files (*)"};
        String [] filterExtensions = new String [] {"*"};
        String filterPath = "c:\";
        dialog.setFilterNames (filterNames);
        dialog.setFilterExtensions (filterExtensions);
        dialog.setFilterPath (filterPath);
        dialog.open();
        System.out.println ("Selected files: ");
        String[] selectedFileNames = dialog.getFileNames();
        for(String fileName : selectedFileNames) {
            System.out.println("  " + fileName);
        }
        shell.close();
        while (!shell.isDisposed ()) {
            if (!display.readAndDispatch ()) display.sleep ();
        }
        display.dispose ();
    }
}
