【问题描述】:
我正在尝试创建一个个人 DnD 字符表程序。主要想法是有 4 个大面板,每个面板都包含基本字符表的主要部分之一。我目前正在研究第一个具有统计数据和保存投掷的面板。在制作这个时,我试图让 GridBagLayout 更舒服,但我在设置网格时遇到了问题。我已经访问过不遵守 gridx 和 gridy 的 GridBagLayout 并且(除非我只是愚蠢),这对我没有帮助。我将 GridBagLayout 和 GridBagConstraints 用于 statsPanel() 并且 gridy 工作得很好。
这就是问题所在:每当我在proficinciesAndSkillsPanel() 中将gridy 设置为下一个网格时,它都会被视为我刚刚更改了gridx。我的目标是一列多行,而不是一行多列。感谢您的宝贵时间
