java - 设置包含 JRadioButton 的 JPanel 的大小

Question

我有一些问题，我希望我的 jpanel 看起来像这样 但在编码之后我有这个观点，但我没有找到解决方案， 我需要一些帮助。

我把单选按钮放在jScrollPan里面//listmateriel是单选按钮的列表( vector )----------//imagebox是jpanel，包含jradio按钮和图像---------

//gridlayoutPanel2是Jpanel，包含两个文本字段和jlabel以及一个JComboBox

GridLayout(0, 1) 而不是 BoxLayout 是解决方案，谢谢@trashgod
