How to display checkboxes instead of boolean in vaadin grid?

Question

I'm trying to display my boolean values as a checkbox in a vaadin grid. I can't use the multi selection mode because i need two columns with checkboxes. The columns of the Checkboxes shell have a Caption but the Checkboxes itself shell be without a caption. Does anyone have an idea ?

You have to add generated columns for your checkboxes

    GeneratedPropertyContainer gpcontainer = new GeneratedPropertyContainer(container);
    gpcontainer.addGeneratedProperty("columnName",
        new PropertyValueGenerator<CheckBox>() {
        @Override
        public CheckBox getValue(Item item, Object itemId,
                                Object propertyId) {

            // set checkBox listener etc. in here
            return new CheckBox();
        }

        @Override
        public Class<CheckBox> getType() {
            return CheckBox.class;
        }
    });

Grid grid = new Grid(gpcontainer);

You can find more detailed example in here in section "GeneratedPropertyContainer"

EDIT: Also set `ComponentRenderer' for your column

mainGrid.addColumn(COLUMN).setRenderer(new ComponentRenderer())
