GridBagLayout困难

Question

我只想使用GridBagLayout布局组件，如图所示
我尝试了几个约束，但最终都没有得到预期的结果，所以我想知道，仅使用GridBagLayout是否真的可行。困难在于C1、C2和C3部件
C1和C2是一个组件，它将容纳其他组件，如JPanel。我已经设置了它们的最小尺寸和首选尺寸。C3是一个按钮 GUI无法调整大小
这个布局管理器我已经用了好几次了，但还是不太熟练，谢谢你的帮助。

Answer 1

恐怕这是不可能的。GridBagLayout无法计算出C1开始和C3开始之间的适当距离。

Answer 2

只需填写第一行（仅）中所有所需的列数，即可创建矩阵，您可以定义GBC weightx、weighty、gridx、gridy和/或锚定
