问题描述

我是vVadin的新手。我创建了一个带有两列网格的项目，但是我想添加一个Textfield列和一个复选框列，并在单击标题复选框时选中所有复选框。

Ia m new to vVadin. I created one project with grid with two columns but i want to add one Textfield column and one checkbox column and check all checkboxes when click on header checkbox.

List<Person> people = Arrays.asList(
            new Person("Nicolaus Copernicus", 15),
            new Person("Galileo Galilei", 15),
            new Person("Johannes Kepler", 15));
     TextField txt =new TextField();
      CheckBox chk=new CheckBox();
        // Create a grid bound to the list
        Grid<Person> grid = new Grid<>();
        grid.setItems(people);
        grid.addColumn(Person::getName).setCaption("Name");
        grid.addColumn(Person::getAge).setCaption("Year of birth");
       grid.addColumn(Person-> new TextField());


        layout.addComponents(grid);


    setParent(layout);

推荐答案

通过复选框选择适用于多选模式，请参阅 docs 。在同一页面上，您可以阅读 ComponentRenderer ，它允许将任何组件放入列中。请注意，此功能自Vaadin 8.1起可用。几天前发布。

Selection via check boxes works with the multi selection mode, see docs. On the same page you can read about ComponentRenderer which allows to put any component in a column. Note that this feature is available since Vaadin 8.1. released few days ago.
