如何使用JavaFX CheckBoxTreeTableCell? [英] How to Use JavaFX CheckBoxTreeTableCell?

问题描述

我一直在尝试使用JavaFX CheckBoxTreeTableCell提供的单元工厂，但是我不知道如何使它工作.

I have been trying to use the cell factories that are provided by the JavaFX CheckBoxTreeTableCell, but I can't figure out how to make it work.

Javadoc似乎与实现不匹配.例如:

The Javadoc does not seem to match the implementation. For example:

公共静态< S，T>回调< TreeTableColumn< S，T>，TreeTableCell< S，T> forTreeTableColumn(Callback< Integer ，ObservableValue< Boolean>> getSelectedProperty)

public static <S,T> Callback<TreeTableColumn<S,T>,TreeTableCell<S,T>> forTreeTableColumn(Callback<Integer,ObservableValue<Boolean>> getSelectedProperty)

...

参数:

getSelectedProperty-给定类型为TreeTableColumn< S，T> 的对象的回调将返回ObservableValue< Boolean>.表示是否选择了给定的项目.

getSelectedProperty - A Callback that, given an object of type TreeTableColumn<S,T>, will return an ObservableValue<Boolean> that represents whether the given item is selected or not.

整数表示什么?有没有人知道如何使用它的示例代码?

What does the Integer represent? Does anyone have any example code of how this is intended to be used?

谢谢， 罗布

推荐答案

我认为您想使用forTreeTableColumn(TreeTableColumn列).

I think you want to use forTreeTableColumn(TreeTableColumn column).

    final TreeTableView<Integer> integerTreeTableView = new TreeTableView<>();
    final TreeTableColumn<Integer, Boolean> column = new TreeTableColumn<>();
    column.setCellFactory(CheckBoxTreeTableCell.forTreeTableColumn(column));
    column.setCellValueFactory(param -> {
                if(param.getValue().getValue() > 5) {
                    return new SimpleBooleanProperty(true);
                } else {
                    return new SimpleBooleanProperty(false);
                }
            });
    integerTreeTableView.getColumns().add(column);
