带有 GridBagLayout 的 JPanels 大小不正确

如何解决带有 GridBagLayout 的 JPanels 大小不正确

我正在尝试设置一个拼图编辑器/解算器，左侧有一个可交互的画布，右上角有可选工具，一个大的“解决”按钮和右下角的一些重播按钮。我使用了几个 GridBagLayouts（一个用于主布局，一个用于按钮），并且在这两个地方看起来大小和边距都没有正确计算。

这是它显示的内容的图片：

我想要的是内容周围的 10 像素边距，以及每个右侧部分内的 10 像素边距，但它给了我顶部 15 像素的边距，天知道在什么底部和侧面。子 JPanel 的大小也不正确，因为您可以看到内容对于窗口来说太大了。我为单选按钮使用了一个简单的框布局，并且那里的大小或边距似乎没有任何问题。我使用预期的像素值作为网格权重，因为在我看来，这应该正确调整它们的大小。任何想法为什么边距和尺寸完全被破坏？

附上相关代码。 EditorToolsGroup 是创建单选按钮的子组件。 SolveButtons 是创建求解/重播按钮的子组件。如果需要，我可以包含 SolveButtons 的代码，但实际上并没有什么不同。
