关于JTabeedPane中多个JPane的显示问题

[yaojiesheng]

编译成功后运行,在第二个Pane中的JLabel的内容总出现在第一个Pane中,并且第二个Pane中的JLabel覆盖第一个Pane的JLabel内容.

对于这种UI,楼主是不是都是手工写代码添加的的?
如果是的话,强烈建议使用JBuilder来做.
如果不是的话,建议不要使用XY或Null Layout

[yaojiesheng]

是用手工写代码添加的。问题是我们要求用手工来写

没用过GridBagLayout，但
register.setLayout(gbl);
这里是不是应该新new一个GridBagLayout和GridBagConstraints呢？
