EDT位置有几个JFrame窗口 [英] EDT location with several JFrame window

问题描述

我有一个Swing JFrame。如果我在程序执行期间在新线程中创建一个新的JFrame，那么EDT会是什么？在最后一个JFrame窗口的当前线程中或在第一个窗口中。

I have a Swing JFrame. If I create a new JFrame in a new thread during the program execution where will be the EDT ? In the current thread of the last JFrame window or in the first window.

感谢您的回答。

Thanks for your answers.

我理解他们，我很好。我知道我们不必在EDT的其他地方创建摆动对象，但我遇到问题。

I understand them and i'm ok with them. I know that we don't must create swing object elsewhere that the EDT but I meet problem.

我解释;我开发了一个JAVA应用程序，用于创建和提取存档，如winrar。您可以使用多线程同时创建多个arhive。最近，我希望在每次创建时在新的JFrame中以JprogressBar的形式在存档创建期间添加信息状态。但我的问题是在新的状态框架和创建存档的线程中生成通信。这就是为什么我在存档线程中创建JFrame以更新当前的进度条。

I explain; I developed a JAVA application for create and extract archive like winrar. You can create several arhive in same time with multi-thread. And recently, I wanted add an information status during the archive creation in the form of JprogressBar in a new JFrame at every creation. But my problem is for generate a communication in the new status frame and the thread who create archive. That's why, I create the JFrame in the archive thread for update the progress bar currently.

但是我可以在潜水员信息源和你的答案/评论中阅读它，它反对java摇摆和性能;我不能在EDT的其他地方创建swing对象。

But like i could read it in divers information source and on your answers/comments, it's against java swing and performance; I can't create swing object elsewhere that the EDT.

但是，我应该如何解决我的问题呢？

But then, how should I solve my problem ?

推荐答案

EDT - 事件派发线程 - 与任何具体的GUI组件分开，例如JFrame。

The EDT - the event dispatch thread - is separate from any concrete GUI component, such as a JFrame.

一般来说你应该在EDT上创建所有GUI组件，但这并不意味着他们拥有EDT，EDT也不拥有组件。

Generally you should create all GUI components on the EDT, but that does not mean they own the EDT, nor does the EDT own the components.

要创建两个JFrame，两者都在EDT，您可以执行以下操作：

To create two JFrames, both on the EDT, you can do the following:

public static void main(String[] args) {

    SwingUtilities.invokeLater(new Runnable() {
        public void run() {
            JFrame frame1 = new JFrame("Frame 1");
            frame1.getContentPane().add(new JLabel("Hello in frame 1"));
            frame1.pack();
            frame1.setLocation(100, 100);
            frame1.setVisible(true);
        }
    });

    SwingUtilities.invokeLater(new Runnable() {
        public void run() {
            JFrame frame2 = new JFrame("Frame 2");
            frame2.getContentPane().add(new JLabel("Hello in frame 2"));
            frame2.pack();
            frame2.setLocation(200, 200);
            frame2.setVisible(true);
        }
    });

}
