Java 我在JFrame.setContentPane上有一个索引越界

这行：

this.setContentPane(panelLoading);

告诉我这个错误：

仅当从JComboBox（ActionListener或ItemListener）上的事件调用函数时，使用my函数设置数据库后，此错误才会出现在下一个setContentPane上。

boutonJouer是一个JButton，serveur是一个JComboBox。 请帮帮我

PS：对不起，我的英语不好

谢谢你的卡片布局，我终于找到了解决方案： 在调用函数之前使用CardLayout并移除JcomboBox，然后添加她

remove(serveur); //Remove the JComboBox
fen.setServeur(serveur.getSelectedItem().toString()); //Call the function
add(serveur); //Then add the JCombpBox

它起作用了。

感谢您的帮助。

请考虑提供一份说明您的问题的报告。这不是一个代码转储，而是您正在做的一个示例，它突出了您所遇到的问题。这将减少混乱和更好的响应。您确实应该避免使用

setContentPane

切换视图，或者只需使用新数据更新现有视图，或者如果需要，使用

CardLayout

在视图之间切换谢谢您的CardLayout，使用此解决方案，错误不会出现，但我的JComboBox会显示在面板上。如何解决此错误？

remove(serveur); //Remove the JComboBox
fen.setServeur(serveur.getSelectedItem().toString()); //Call the function
add(serveur); //Then add the JCombpBox
