使用 Swing 在窗格中选择文件 [英] Choosing a file in-pane with Swing

问题描述

我正在 Swing 中编写一个 GUI，我想在其中执行主窗口中的文件选择器，如下图所示:

I'm writing a GUI in Swing where I want to do a file chooser that is in the main window, looking something like the image below:

虽然似乎有很多关于如何编写弹出文件选择器的教程，但我没有看到太多关于如何在 Swing 中完成这种类型的选择器的信息.

while there seem to be quite a few tutorials on how to write a popup file chooser, i don't see much information on how this type of chooser might be accomplished in swing.

如果之前有人问过这个问题，我也很抱歉，我四处搜索，但找不到其他任何东西..

also sorry if this has been asked before, i did a good bit of searching around and wan't able to find anything else..

推荐答案

JFileChooser 实际上扩展了 JComponent，因此您可以像使用任何其他组件一样使用.这是一个带有两个窗格内文件选择器的示例:

JFileChooser actually extends JComponent, so you can use like any other component. Here is an example with two in-pane file choosers:

public class TestInPaneChoosers {
    public static void main(String[] args) {
        EventQueue.invokeLater(new Runnable() {
            @Override
            public void run() {
                buildFrame();
            }
        });
    }

    private static void buildFrame() {
        JFrame f = new JFrame("Test");
        f.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);

        f.setLayout(new FlowLayout());

        f.add(new JFileChooser());
        f.add(new JFileChooser());

        f.pack();
        f.setLocationRelativeTo(null);
        f.setVisible(true);
    }
}
