JavaFX笔记

这是用来存放一些Java FX中代码写法的仓库，可能会比较乱，以后可能会腾出时间啊整理，但谁知道呢😀

JavaFX事件监听

//Controller.java
@FXML public void handleChoice(MouseEvent event) {
        //box.getSelectionModel().selectedIndexProperty().addListener(new ChoiceEvnt(check,box));
        //写法Ⅰ

        box.getSelectionModel().selectedIndexProperty().addListener(
                (ObservableValue<? extends Number> ov,
                    Number old_val,Number new_val)->{
                    if (box.getSelectionModel().getSelectedIndex()==0)
                        check.setSelected(false);
                    else
                        check.setSelected(true);
                });
    }
    //写法Ⅱ

//ChoiceEvnt.java
public class ChoiceEvnt implements ChangeListener<Number> {
    CheckBox checkBox;
    ChoiceBox choiceBox;

    public ChoiceEvnt(CheckBox checkBox, ChoiceBox choiceBox) {
        //System.out.println("Created.");
        this.checkBox = checkBox;
        this.choiceBox = choiceBox;
    }

    @Override
    public void changed(ObservableValue<? extends Number> observable, Number oldValue, Number newValue) {
        System.out.println("Change.");
        if ((int)choiceBox.getSelectionModel().getSelectedIndex()==0)
        {
            checkBox.setSelected(false);
            System.out.println("select 1");
        }
        else
        {
            checkBox.setSelected(true);
            System.out.println("select 2");
        }
    }
}
