如何在编辑后获取TableView列数据？
我在编辑后尝试获取数据，但一次又一次地获取以前的值。我在onEditStart上使用了一个onEditCancel属性，比如 - ：
FXml代码 - ：
<TableColumn editable="true" maxWidth="5000.0" minWidth="10.0" onEditCancel="#editEnd_0" onEditStart="#editStart_0" onEditCommit="#editCommit_0" prefWidth="136.0" text="Description Of Goods" fx:id="value_0" />
在控制器文件中实现oneditStart_0和onEditEnd_0以及editCommit_0。
public void editStart_0()
{
int a = tableView.getSelectionModel().getSelectedItem().getValue_0();
System.out.println("Getting Sales column data on Update -"+a);
String b = value_0.getText();
System.out.println("\"Getting Sales column data on Update -"+b);
}
public void editCommit_0(CellEditEvent<String,String> event)
{
System.out.println("Value edited: On edit new value is "+event.getNewValue());
}
public void editEnd_0()
{
int a = tableView.getSelectionModel().getSelectedItem().getValue_0();
System.out.println("Getting Sales column data after Update -"+a);
}
编辑前
编辑后
输出 - ：
Getting Sales column data on Update -29
"Getting Sales column data on Update -Description Of Goods
Getting Sales column data after Update -29
但是当我在更新后进入它抱怨 - ：
错误 - ：

答案 0 :(得分：1)
您需要实现onEditCommit，方法与实现其他方法的方式相同。 onEditCancel定义（顾名思义）用户取消编辑时调用的方法（通常按Escape）。
<TableColumn editable="true" maxWidth="5000.0" minWidth="10.0" onEditCancel="#editEnd_0"
onEditStart="#editStart_0" onEditCommit="#editCommit_0" prefWidth="136.0" text="Description Of Goods" fx:id="value_0" />
和
public void editCommit_0(CellEditEvent<S,T> event) {
System.out.println("Value edited: new value is "+event.getNewValue());
}
您可以分别用S和T的相应类型替换TableView和TableColumn。
