JProgresbar不能与Files.copy一起使用 [英] JProgresbar doesn't work with Files.copy

问题描述

我正在编写一个程序，为特定文件夹中的每个文件创建一个文件夹。之后，文件被复制到刚刚创建的文件夹中。一切正常，除了JProgressbar我想添加到程序。我也添加了一个Jtextarea，但在一个文件被复制后，我想改变进度条，并添加一些文本到JTextarea。而程序运行没有任何显示，但当整个任务完成时，我想要的JTextArea中的所有文本显示，进度条是100％。

I am writing a program that creates a folder for each file in a specific folder. After that the file is copied in the, just created, folder. Everything works, except the JProgressbar I want to add to the program. I also added a Jtextarea but after a file is copied i want to change the progress bar, and add some text to the JTextarea. while the program runs nothing appears but when the whole task is completed all of the text I want in the JTextArea is shown and the progress bar is 100%. I don't know what i did wrong.

推荐答案

之后的示例 MadProgrammer 给了我。我想出了它是如何工作的。你需要在Swingworker和你想要调用的所有方法中更新你的进度条，你需要在SwingworkerMethod中调用它们。

After the examples that MadProgrammer gave me. I figured out how it worked. You need to update your progresbar in the Swingworker and all the Methodes you want to call, you need to call them in the SwingworkerMethod.
