java - 使用GridBagLayout时组件重叠

在放置JLabels时，我发现了一个问题，直到现在我还是无法解决。 JLabel是重叠的。

这是有关gridbaglayout的代码的摘录：

   c = new GridBagConstraints();

   c.gridx = 0;
   c.gridy = 0;
   c.gridwidth = 3;
   c.fill = GridBagConstraints.HORIZONTAL;
   c.ipady = 20;
   c.weightx = 3;
   c.weighty = 1;
   c.insets = new Insets(0,5,5,5);

   all.add(header, c);

   c.gridx = 0;
   c.gridy = 1;
   c.weightx = 2;
   c.weighty = 4;
   c.insets = new Insets(5,5,5,5);

   all.add(sts, c); //this label overlapped

   c.gridx = 1;
   c.gridy = 1;
   c.weightx = 1;
   c.weighty = 5;
   c.insets = new Insets(5,5,5,5);

   all.add(cl, c); //this label overlapped

提前致谢

最佳答案

网格宽度为3意味着组件将在x网格上占据3个位置，请阅读网格袋布局教程
http://docs.oracle.com/javase/tutorial/uiswing/layout/gridbag.html

您在x0处有第一个组件，它将扩展3列到x2，因此下一个可用的网格位置是x3
