问题描述

I have a Java Applet to show images. I have a while true loop in paint() in order to permantly receive new images via tcp/ip socket. Now I have the problem, that the app is still requesting new Images from the server, even when the tab is closed. How can I fix that?

推荐答案

只是要清楚：

我在 A ，而（真）循环的paint（）为了永久接收通过TCP新形象/ IP套接字。

I have a while(true) loop in paint() in order to permanently receive new images via tcp/ip socket.

不要这样做。 paint方法不应该阻止一个较长的时间框架。它不应该的只有的画你的图片，没有别的。 （只要paint方法运行，其他什么都在你的GUI可以做任何事情。这可能不是你的小应用程序的关键，但是这将是更复杂的程序。）

Don't do this. The paint method should never block for a longer time frame. It should only paint your images, nothing else. (As long as the paint method is running, nothing else in your GUI can do anything. This may not be critical for your applet, but it will be for more complicated programs.)

如果您需要加载新的图像，在一个单独的线程做到这一点，把图像中的变量，并调用重绘（）结尾。然后paint方法从变量取图像，并将其绘制到屏幕上。

If you need to load new images, do this in a separate thread, put the image in a variable, and call repaint() at the end. The paint method then takes the image from the variable and draws it to the screen.
