如何在不使用JFileChooser的情况下打开Java Swing中的文件 [英] How to open files in Java Swing without JFileChooser

问题描述

我使用的是Java Swing（GUI），我想添加一个按钮到我的项目打开文件。

我不喜欢 JFileChooser ，因为它打开了一个浏览目录文件的小窗口。我可以在Java Swing下使用其他的而不是 JFileChooser 吗？

我试过使用SWT的元素，但是它没有工作，意思是使用按钮对象，然后在 JFrame ，但是失败了，所以我想SWT和Swing不能混合在一起？

下面是开始。将其更改为需要：

..所以我想SWT和Swing不会混在一起？

在同一个顶级容器中混合使用Swing / AWT / SWT组件通常不是一个好主意。 STRONG>。在基于Swing的 JFrame 上打开AWT FileDialog 不是问题，因为它们都是顶级容器。我很肯定，这同样适用于Swing / SWT或AWT / SWT。

I'm using Java Swing (GUI) and I want to add a button to my project for opening files.

I don't like the JFileChooser since it opens a small window for browsing through the files of the directories. Can I use something else instead of the JFileChooser under Java Swing?

I've tried to use elements of SWT but it didn't work, meaning is the use of the button object and then use it inside the JFrame, but that failed, so I guess SWT and Swing don't mix together?

Here is the example of Java Swing with JFileChooser and I'm looking for something like this to put in my JFrame.

解决方案

JFileChooser with the native PLAF seems to fulfill the stated requirement.

import javax.swing.JFileChooser;
import javax.swing.SwingUtilities;
import javax.swing.UIManager;

public class NativeFileChooser {

    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {
            @Override
            public void run() {
                try {
                    UIManager.setLookAndFeel(
                            UIManager.getSystemLookAndFeelClassName());
                } catch(Exception e) {
                    e.printStackTrace();
                }
                JFileChooser jfc = new JFileChooser();
                jfc.showOpenDialog(null);
            }
        });
    }
}

Still not quite to your liking? Then you might start with this one & change it to need:

..so I guess SWT and Swing don't mix together?

It is generally not a good idea to mix Swing/AWT/SWT components in the same top-level container. It is not a problem to open an AWT FileDialog over a Swing based JFrame since they are both top-level containers. I am pretty sure the same would apply to Swing/SWT or AWT/SWT.
