JavaFx8 Tableview 更新 ObservableList
JavaFx8 Tableview updating ObservableList
我在 table 中有一个 table 视图 我有一个复选框 当我 select 行制作这个复选框时我需要一些东西 selected 和其他检查要删除的箱子select
我通过在 table 视图上设置侦听器并遍历列表项并设置为 checked false 并且只有 selected 行为 true 来解决它，但我遇到的问题是当我调用 ObservableList.setall( ...) 在我的代码
之后我得到了这些异常
AccountingFilesTable.getSelectionModel().selectedItemProperty().addListener(
(observable, oldValue, newValue) -> showAccountingFilesDetails(newValue));
private void showAccountingFilesDetails(AccountingFiles newValue) {
AccountingFiles curraccfile = AccountingFilesTable.getSelectionModel().getSelectedItem();
AccountingFilesTable.getSelectionModel().clearSelection();
System.out.println(curraccfile.getAccountingFilesName());
for (AccountingFiles af : accountingData) {
mainEm.getTransaction().begin();
af.setAccountingFilesActiveStatus(false);
mainEm.getTransaction().commit();
//accountingData.set(accountingData.indexOf(af), af);
System.out.println("in looooooooooooop");
}
mainEm.getTransaction().begin();
curraccfile.setAccountingFilesActiveStatus(true);
mainEm.getTransaction().commit();
List<AccountingFiles> listOfAccountingFiles = mainEm.createNamedQuery("AccountingFiles.findAll").getResultList();
accountingData.setAll(listOfAccountingFiles);
}

我尝试添加按钮，并在 actionlistener 上调用了 showAccountingFilesDetails 它起作用了，没有发生异常，但我不明白为什么，我不想 select 行并按下按钮来执行我的代码，这样做很尴尬...

这不会在选中任何复选框时 un-check 其他复选框，因为我认为这不是一个好主意。如果您希望它以这种方式工作，只需添加回环即可。

已满 class。 我尝试添加按钮，并在 actionlistener 上调用了 showAccountingFilesDetails 它起作用了，没有发生异常，但我不明白为什么，我不想 select 行并按下按钮来执行我的代码，这样做很尴尬...
大家好谢谢大家的回复我已经制作了一个 MCVE

这不会在选中任何复选框时 un-check 其他复选框，因为我认为这不是一个好主意。如果您希望它以这种方式工作，只需添加回环即可。
for (Player pl : players) {
pl.setSelected(false);
