JDialog 中的 JList 大小
JList size in JDialog
我正在按照 采用 JList 并在我的 JDialog 中调用 setVisibleRowCount()。
我尝试将行数限制为 2；然而，对话框被打包成一个大的、未滚动的 JList。我预计它只会显示 2 行，其余的将通过滚动到达，将 space 留给设计中未来的第三个元素（订单列表）。
请看一下SSCCE。

setVisibleRowCount() 仅当 JList 是 JScrollPane 的视图（即 JScrollPane 的主要子视图）时才有效。在您的程序中，JScrollPane 的视图是 JPanel，而不是 JList。
我正在按照 JList 并在我的 JDialog 中调用 setVisibleRowCount()。
我尝试将行数限制为 2；然而，对话框被打包成一个大的、未滚动的 JList。我预计它只会显示 2 行，其余的将通过滚动到达，将 space 留给设计中未来的第三个元素（订单列表）。
