如果在不同的布局中使用，则Applet组件不可见

Question

我正在为电子签名开发 applet ，我需要对组件进行一些更改。我有一个名为geriButton的按钮，它在jPanel2和jPanel10中使用。

它显示在jPanel10但不显示在jPanel2。我的geriButton也需要jPanel2。我试图找到答案，但没有运气。我提供了以下代码。谢谢！

编辑：我创建了另一个名为geriButton2的组件并提供了相同的功能并且它有效。 但是，我想在geriButton和jPanel2中使用相同的组件jPanel10。希望有人能搞清楚。

EDIT2：

jPanel2和jPanel10应该这样。我的意思是，我需要在geriButton和jPanel2中放置相同的组件（jPanel10）
