JFileChooser vs JDialog vs FileDialog [英] JFileChooser vs JDialog vs FileDialog

问题描述

我需要知道3对哪一个最适合我。我的要求按重要性排列如下：

I need to know which of the 3 is best for me. My requirements are as follows in order of importance:

• 轻松保存和加载文件。


• 文件类型过滤 文件选择期间（之后）。


• 外观与完全相同，与本机操作系统L& F相同。

• Save and load files with ease.
• File type filter during file selection (not afterwards).
• Look and feel is exactly the same as the native OS L&F.

如果有一个我没有提到的对话会更理想，请告诉我。

If there is a dialog that I've not mentioned that would be more ideal, please let me know.

推荐答案

您的应用程序的其余部分是什么？如果你使用AWT，你应该使用 FileDialog 。如果你使用Swing，你应该使用 JFileChooser 。这两个类都满足您的所有要求。 （ JDialog 只是一个空窗口，如果你向它添加 Component ，你只能使用它来打开文件，而 JFileChooser 已经为你做了这个。）

What is the rest of your application written in? If you used AWT you should use FileDialog. If you used Swing you should use JFileChooser. Both classes meet all of your requirements. (A JDialog is simply an empty window, you can only use it to open files if you add a Component to it which allows you to, and JFileChooser already does this for you.)

保存和加载必须用你自己的方法写， JFileChooser 和 FileDialog 只能用于选择文件。

Saving and loading has to be written with your own methods, both JFileChooser and FileDialog can only be used to select file(s).

两者 FileDialog的 和 JFileChooser 在选择期间支持文件过滤器。

Both FileDialog and JFileChooser support file filters during selection.

FileDialog 的默认UI是本机操作系统'。 JFileChooser （实际上，您的整个应用程序）UI可以使用 UIManager.setLookAndFeel（UIManager.getSystemLookAndFeelClassName（））设置为本机操作系统。

FileDialog's default UI is the native OS'. JFileChooser's (in fact, your entire applicatin's) UI can be set to the native OS' with UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName()).
