将CellValueFactory设置为JavaFX TableColumn中的数据对象
我有一个带有自定义单元渲染的tablecolumn此单元渲染将对象作为标签渲染其属性。问题是我找不到将arraylist中的同一对象传递给列的方法。这是我的密码:将CellValueFactory设置为JavaFX TableColumn中的数据对象,java,javafx-2,Java,Javafx 2,我有一个带有自定义单元渲染的tablecolumn此单元渲染将对象作为标签渲染其属性。问题是我找不到将arraylist中的同一对象传递给列的方法。这是我的密码: //I want to render this object in a column as well as use it in the rest of columns CustomerCreationFlow cflow=new CustomerCreationFlow(); cflow.setId(10L);

//我试过了,但没用
flowclm.setCellValueFactory(新的PropertyValueFactory(“本”));

流程表。设置项目(数据);
有什么建议吗?您应该通过扩展TableCell来实现自定义CellFactory。 在自定义TableCell中,可以通过获取当前TableCell的TableRow来获取表行的值(逻辑上为CustomerCreationFlow) 这就产生了:
class MyTableCell<S,T> extends TableCell<S, T>
@Override
public void updateItem(final T item, final boolean empty) {
super.updateItem(item, empty);
if (empty) {
this.setText(null);
this.setGraphic(null);
} else {
S item = (S) this.getTableRow().getItem();
// DO STUFF HERE
}
}
}
类MyTableCell扩展了TableCell
@凌驾
公共void updateItem(最终T项,最终布尔值为空){
super.updateItem(项,空);
if(空){
this.setText(null);
此.setGraphic(null);
}否则{
S item=(S)this.getTableRow().getItem();
//在这里做事
}
}
}
T是CellValueFactory定义的数据类型。S是表示行的数据类型。谢谢。this.getTableRow().getItem();这就是我要找的。
