显示SVG时无限循环，发现问题，无法解决
我有一个奇怪的问题。有人能告诉我为什么我的虚空“绘画”会进入无限循环吗？我检查了一下，只有当 this.setURI(fi.toURL().toString()) 被 try/catch 包围时，它才会变得无限。当我启动程序时，它一直打印 svinja 直到我关闭它（这是我对无限循环的测试）；我是初学者，想要最简单的解决方案。 [： 提前致谢。
ps 我有所有必要的库，所以这不是问题。
public class SVG_class extends JSVGCanvas {
@Override
public void paint(Graphics g) {
System.out.println("svinja");
super.paint(g);
File fi = new File("C:\\Users\\Gigabyte\\Desktop\\SVG\\map1.svg");
try {
this.setURI(fi.toURL().toString());
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
I have a strange problem. Can somebody tell me why does my void "paint" go into an infinite loop. I checked and it only goes infinite when there is this.setURI(fi.toURL().toString()) surrounded with try/catch. When i start the program it prints svinja all the time until i close it (that's my test for infinite loop); I'm a beginner and would like the simplest solution. [: Thanks in advance.
p.s. I have all the necessary libraries so that's not a problem.
public class SVG_class extends JSVGCanvas {
@Override
public void paint(Graphics g) {
System.out.println("svinja");
super.paint(g);
File fi = new File("C:\\Users\\Gigabyte\\Desktop\\SVG\\map1.svg");
try {
this.setURI(fi.toURL().toString());
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}

最有可能的是
this.setURI导致paint被调用。这是因为加载新模型后需要重新绘制。解决方案是将setURI调用从paint中取出。它不属于那里。most likely the
this.setURIresults inpaintbeing called. Which makes since since it would need to repaint after loading a new model. the solution would be take thesetURIcall out ofpaint. It doesn't belong there.
