带复选框的 Javafx 8 Tableview 选择

我已经设置了一个启用多选的表视图，并尝试将插入列中的复选框的侦听器附加到表的选择模型。

checkBoxTableColumn.setCellValueFactory(
            cellData -> {
                CheckBox checkBox = new CheckBox();
                ObjectProperty<CheckBox> sop = new SimpleObjectProperty<CheckBox>();
                sop.setValue(checkBox);
                sop.getValue().setText("");



                sop.getValue().selectedProperty().addListener(
                        (obsv, oldv, newv) -> {
                            ArrayList<Job> tempSelectionArray = new ArrayList<>();

                            if(newv.booleanValue()){
                                tempSelectionArray.addAll(jobTableView.getSelectionModel().getSelectedItems().stream().collect(Collectors.toList()));
                                this.jobTableView.getSelectionModel().clearSelection();
                                for(Job job: tempSelectionArray){
                                    jobTableView.getSelectionModel().select(job);
                                }

                                tempSelectionArray.clear();
                            }
                            else{
                                tempSelectionArray.addAll(this.jobTableView.getSelectionModel().getSelectedItems().stream().collect(Collectors.toList()));
                                this.jobTableView.getSelectionModel().clearSelection();
                                tempSelectionArray.remove(getJobTableView().getFocusModel().getFocusedItem());
                                for(Job job: tempSelectionArray){
                                    this.jobTableView.getSelectionModel().select(job);
                                }
                                tempSelectionArray.clear();
                            }
                        }
                );
                ObservableValue<CheckBox> ov = sop;

                return ov;
            }

但这不会改变桌子的选择。

按法官所述编辑

        checkBoxTableColumn.setCellFactory(new Callback<TableColumn<Job, Boolean>, TableCell<Job, Boolean>>() {
        @Override
        public TableCell<Job, Boolean> call(TableColumn<Job, Boolean> param) {
            return new CheckBoxCell(jobTableView);


        }
    });

复选框单元格如下

class CheckBoxCell extends TableCell<Job, Boolean>{
private CheckBox checkBox;
private TableView<Job> jobTableView;

public CheckBoxCell(TableView<Job> tableView){
    this.jobTableView = tableView;
}
@Override
public void updateItem(Boolean item, boolean empty) {
    super.updateItem(item, empty);

    checkBox = new CheckBox();
    setGraphic(checkBox);

    checkBox.selectedProperty().addListener(
            (obsv, oldv, newv) -> {
                ArrayList<Job> tempSelectionArray = new ArrayList<>();

                if(newv.booleanValue()){
                    tempSelectionArray.addAll(jobTableView.getSelectionModel().getSelectedItems().stream().collect(Collectors.toList()));
                    this.jobTableView.getSelectionModel().clearSelection();
                    for(Job job: tempSelectionArray){
                        jobTableView.getSelectionModel().select(job);
                    }

                    tempSelectionArray.clear();
                }
                else{
                    tempSelectionArray.addAll(this.jobTableView.getSelectionModel().getSelectedItems().stream().collect(Collectors.toList()));
                    this.jobTableView.getSelectionModel().clearSelection();
                    tempSelectionArray.remove(jobTableView.getFocusModel().getFocusedItem());
                    for(Job job: tempSelectionArray){
                        this.jobTableView.getSelectionModel().select(job);
                    }
                    tempSelectionArray.clear();
                }
            }
    );
}

}

这次监听器不起作用了......

在控制器的初始化方法中：

        jobTableView.getSelectionModel().setSelectionMode(SelectionMode.MULTIPLE);


    checkBoxTableColumn.setEditable(true);
    checkBoxTableColumn.setCellValueFactory(
            new PropertyValueFactory<Job, Boolean>("isContextSelected")
    );

    checkBoxTableColumn.setCellFactory(
            new Callback<TableColumn<Job, Boolean>, TableCell<Job, Boolean>>() {
                @Override
                public TableCell<Job, Boolean> call(TableColumn<Job, Boolean> param) {
                    return new CheckBoxTableCell<Job, Boolean>(){
                        {
                            setAlignment(Pos.CENTER);
                        }

                        @Override
                        public void updateItem(Boolean item, boolean empty){
                            if(!empty){
                                TableRow row = getTableRow();

                                if(row != null){
                                    Integer rowNumber = row.getIndex();
                                    TableView.TableViewSelectionModel sm = getTableView().getSelectionModel();

                                    if(item){
                                        sm.select(rowNumber);

                                    }
                                    else{
                                        sm.clearSelection(rowNumber);

                                    }
                                }
                            }

                    };
                }

好的，这是一种方法。您的支持模型中需要一个 BooleanProperty 来保存复选框的值，以便当行滚动到视图之外然后再次返回时，表将“记住”是否应选择该行复选框。

TableColumn<Job,Boolean>  checkCol = new TableColumn<>("Check");
checkCol.setCellValueFactory( new PropertyValueFactory<Job,Boolean>( "checkBoxValue" ) );
checkCol.setCellFactory( new Callback<TableColumn<Job,Boolean>, TableCell<Job,Boolean>>()
{
    @Override
    public TableCell<Job,Boolean> call( TableColumn<Job,Boolean> param )
    {
        return new CheckBoxTableCell<Job,Boolean>()
        {
            {
                setAlignment( Pos.CENTER );
            }
            @Override
            public void updateItem( Boolean item, boolean empty )
            {
                if ( ! empty )
                {
                    TableRow  row = getTableRow();

                    if ( row != null )
                    {
                        int rowNo = row.getIndex();
                        TableViewSelectionModel  sm = getTableView().getSelectionModel();

                        if ( item )  sm.select( rowNo );
                        else  sm.clearSelection( rowNo );
                    }
                }

                super.updateItem( item, empty );
            }
        };
    }
} );
checkCol.setEditable( true );
checkCol.setMaxWidth( 50 );
checkCol.setMinWidth( 50 );
