我在复制文件和目录方面遇到了一些问题。我有一个按钮和一个源路径和目标路径的文本框。
我想知道如果我点击源路径我可以选择目录是否可能，我也可以选择要复制的文件并将其放到目标路径。
这是我目前的代码

PS：我使用的是SWT和WindowsBuilder，我只能选择目录而不是文件。
答案 0 :(得分：0)
查看FileDialog而不是使用DirectoryDialog
示例：的
FileDialog dialog = new FileDialog(shell, SWT.OPEN);
dialog.setFilterExtensions(new String [] {"*.html"});
dialog.setFilterPath("c:\\temp");
String result = dialog.open();
FAQ How do I prompt the user to select a file or a directory?
