How to add CheckBox's to a TableView in JavaFX

Question

In my Java Desktop Application I have a TableView in which I want to have a column with CheckBoxes.

I did find where this has been done http://www.jonathangiles.net/

Answer 1

This is the way is do it

tbcSingleton.setCellValueFactory(data -> data.getValue().singletonProperty());
tbcSingleton.setCellFactory( param -> {
    return new TableCell(){
        {
            setAlignment(Pos.CENTER);
        }
        protected void updateItem(Boolean item, boolean empty){
            if(!empty && item!=null) {
                CheckBox cb = new CheckBox();
                cb.setSelected(item);
                cb.setFocusTraversable(false);
                cb.selectedProperty().addListener((obs,old,niu)->listaFXMLController.get(getIndex()).setSingleton(niu));
                setGraphic(cb);
            }else
                setGraphic(null);
        }
    };
});

• cb.setFocusTraversable(false) is necesary to prevent focus getting stuck on it.

• setGraphic(null) is necesary to erase anything left behind after deleting an item or whenever the source list changes

• cb.selectedProperty().addListener((obs,old,niu)->(your stuff...)); this is where you catch the new value of the CheckBox and do whatever you want with it.

Heres another one with a ToggleGroup and ToggleButtons

tbcTipoControlador.setCellValueFactory(data -> data.getValue().controllerTypeProperty());
tbcTipoControlador.setCellFactory( param -> {
    return new TableCell() {
        {
            setAlignment(Pos.CENTER);
        }
        protected void updateItem(ControllerType item, boolean empty){
            if(!empty && item!=null) {
                ToggleButton tbModal = new ToggleButton("Modal");
                tbModal.selectedProperty().addListener((obs,old,niu)->{
                    if(niu)
                        listaFXMLController.get(getIndex()).setControllerType(ControllerType.MODAL);
                });
                tbModal.setSelected(item.equals(ControllerType.MODAL));
                ToggleButton tbPlain = new ToggleButton("Plain");
                tbPlain.selectedProperty().addListener((obs,old,niu)->{
                    if(niu)
                        listaFXMLController.get(getIndex()).setControllerType(ControllerType.PLAIN);
                });
                tbPlain.setSelected(item.equals(ControllerType.PLAIN));
                ToggleButton tbApplication= new ToggleButton("Application");
                tbApplication.selectedProperty().addListener((obs,old,niu)->{
                    if(niu)
                        listaFXMLController.get(getIndex()).setControllerType(ControllerType.APPLICATION);
                });
                tbApplication.setSelected(item.equals(ControllerType.APPLICATION));
                ToggleGroup gp = new ToggleGroup();
                tbModal.setFocusTraversable(false);
                tbPlain.setFocusTraversable(false);
                tbApplication.setFocusTraversable(false);
                tbModal.setPrefWidth(120);
                tbPlain.setPrefWidth(120);
                tbApplication.setPrefWidth(120);
                gp.getToggles().addAll(tbModal,tbPlain,tbApplication);
                HBox hb = new HBox();
                hb.setAlignment(Pos.CENTER);
                hb.getChildren().addAll(tbModal,tbPlain,tbApplication);
                setGraphic(hb);
            }else
                setGraphic(null);
        }
    };
});

I did some test and memory consumption is basically the same as using a ComboBoxTableCell

This is how my little application looks (sry, my main language is Spanish and i build it for personal use)
