我想要的是搜索文件＆＃39;功能在路径文本域的右侧。
搜索文本字段的位置现在很好，但我不知道如何在其上添加功能。
它应该显示一个文件，其中包含用户在搜索文本字段中键入的单词。 （仅限当前目录中的文件。不需要在子目录中显示文件）
当搜索文本字段为空时，它应该像往常一样显示当前目录中的所有文件。
请帮我解决这个问题。
答案 0 :(得分：2)
con.add(pNorth, "North");
不要使用魔术字符串。 API将包含您可以使用的变量：
con.add(pNorth, BorderLayout.NORTH);
它应该显示一个文件，其中包含用户在搜索文本字段
上键入的单词
您需要将DocumentListener添加到Document的{{1}}。无论何时添加或删除文本，都会触发事件，然后您可以进行搜索。
阅读How to Write a DocumentListener上Swing教程中的部分，了解更多信息和示例。
