【问题描述】:
我正在尝试将我的程序绑定到在 SceneBuilder 中设计的 GUI。 我已经设法让我的“Accounts.class”ID 在最左侧的列表中按需要显示。
现在我需要让 TableView 工作,但我没有运气让它填充数据。
它应该包含来自“Invoice.class”字段的数据, 每个 Account 对象内部都有一个 Set - 这个集合将显示在右侧 TableView 的不同行中。
非常感谢任何帮助!
附言原谅我,我知道它已经被问过很多次,但所有其他解决方案似乎都对我不起作用我尝试在参数中添加类型;
tableAccount.setCellValueFactory(new PropertyValueFactory<Invoice, Account>("id"));
没有运气,这真的很沮丧。从昨晚开始我就一直在乱七八糟,根本没有任何改进,所以在这里发帖是我最后的手段。
