java - 使用 GridBagLayout 时组件重叠

Question

在定位我的 JLabel 时，我发现了一个问题，直到现在我还无法解决。 JLabel 重叠。

这是关于网格布局的代码片段:

   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

Answer 1

gridwidth 为 3 意味着组件将在 x 网格中占据 3 个位置，请阅读 grid bag 布局教程 http://docs.oracle.com/javase/tutorial/uiswing/layout/gridbag.html

第一个组件位于 x0，这会将 3 列扩展到 x2，因此下一个可用网格位置是 x3
