如何使JavaFX TableView单元格可编辑?

问题描述

有很多教程，并且有很多建议可以通过扩展JavaFX单元使其可编辑来实现.一个很好的例子是这个stackoverflow问题.
但是官方教程使用方法调用来创建无需编写所有代码即可通过调用

There are a lot of tutorials, And a lot of suggestions to achieve this by extending JavaFX cells to make them editable. A good one is this stackoverflow question.
But the official tutorials uses a method call to create the callback without writing all that code, By calling

lastNameCol.setCellFactory(TextFieldTableCell.forTableColumn());

但是，当我在代码中执行此操作时(FormTokens是我的模型"):

However when I do this in my code (FormTokens is my "model"):

// At beginning of class declaration
@FXML private TableColumn<FormTokens, String> valuColumn;

// Later at initialization
valuColumn.setCellFactory(TextFieldTableCell.forTableColumn());

编译器说:

如果我删除上面提到的方法调用，则所有工作都将正常进行，但TableView单元格不可编辑.我在做什么错了?

If I remove the method call mentioned above everything works well except that TableView cells are not editable. What am I doing wrong?

我刚刚发现: Javafx TableView无法编辑但是没有解决方案.如何将Callback<TableColumn<Object,...转换为Callback<TableColumn<FormTokens,...?

edit: I just found this: Javafx TableView can not be edited But there are no solutions. How do I cast Callback<TableColumn<Object,... to Callback<TableColumn<FormTokens,...?

推荐答案

为通用参数明确指定确切类型为

Specify the exact type explicitly for generic parameter as

valuColumn.setCellFactory(TextFieldTableCell.<FormTokens>forTableColumn());
