Java 网格袋大小不相等

我对gridbags有问题（我会在最后发布代码）

gridbag有几个面板，包括2个滚动面板

当用户试图调整表单大小时，问题就出现了

首先，它的大小正确，所有面板都正确拉伸，直到它到达上滚动窗格拉伸到滚动条消失的点，此时下滚动窗格的大小减小，在顶部滚动窗格和中间的按钮之间留下很大的间隙

从设计视图（JDEV）来看，一切看起来都很好，我看不到任何可能导致这种情况的因素。我试着把主面板放在另一个面板上作为底座，这没有什么区别

如果有任何机构有任何想法，我都欢迎听取。我想这已经到了我看不见树木的地步

你有它应该是什么样子的模型吗？变量名不应该以大写字符开头。也许没有，但这对表单大小调整不正确没有任何影响
