I am experimenting with JavaFX and I am trying to add a check box Item in tree table, but it looks like it supports only simple tree item.
My Code is modified version of Oracle's TreeTableView Example:
public class TreeTableViewSample extends Application implements Runnable {
List<Employee> employees = Arrays.<Employee>asList(
new Employee("Ethan Williams", 30.0),
new Employee("Emma Jones", 10.0),
new Employee("Michael Brown", 70.0),
new Employee("Anna Black", 50.0),
new Employee("Rodger York", 20.0),
new Employee("Susan Collins", 70.0));
/* private final ImageView depIcon = new ImageView (
new Image(getClass().getResourceAsStream("department.png"))
);
*/
final CheckBoxTreeItem<Employee> root
= new CheckBoxTreeItem<>(new Employee("Sales Department", 0.0));
final CheckBoxTreeItem<Employee> root2
= new CheckBoxTreeItem<>(new Employee("Departments", 0.0));
public static void main(String[] args) {
Application.launch(TreeTableViewSample.class, args);
}
@Override
public void start(Stage stage) {
root.setExpanded(true);
employees.stream().forEach((employee) -> {
root.getChildren().add(new CheckBoxTreeItem<>(employee));
});
stage.setTitle("Tree Table View Sample");
final Scene scene = new Scene(new Group(), 400, 400);
scene.setFill(Color.LIGHTGRAY);
Group sceneRoot = (Group) scene.getRoot();
TreeTableColumn<Employee, String> empColumn
= new TreeTableColumn<>("Employee");
empColumn.setPrefWidth(150);
empColumn.setCellValueFactory(
(TreeTableColumn.CellDataFeatures<Employee, String> param)
-> new ReadOnlyStringWrapper(param.getValue().getValue().getName())
);
TreeTableColumn<Employee, Double> salaryColumn
= new TreeTableColumn<>("Salary");
salaryColumn.setPrefWidth(190);
/* salaryColumn.setCellValueFactory(
(TreeTableColumn.CellDataFeatures<Employee, String> param) ->
new ReadOnlyDoubleWrapper(param.getValue().getValue().getEmail())
);
*/
salaryColumn.setCellFactory(ProgressBarTreeTableCell.<Employee>forTreeTableColumn());
root2.getChildren().add(root);
TreeTableView<Employee> treeTableView = new TreeTableView<>(root2);
treeTableView.getColumns().setAll(empColumn, salaryColumn);
sceneRoot.getChildren().add(treeTableView);
stage.setScene(scene);
stage.show();
ScheduledExecutorService executorService = Executors.newScheduledThreadPool(1);
executorService.scheduleAtFixedRate(this, 3, 10, TimeUnit.SECONDS);
}
@Override
public void run() {
root2.getValue().setSalary(calcSalary(root));
}
public double calcSalary(TreeItem<Employee> t) {
Double salary = 0.0;
if (!t.isLeaf()) {
ObservableList<TreeItem<Employee>> al = t.getChildren();
for (int i = 0; i < al.size(); i++) {
TreeItem<Employee> get = al.get(i);
salary += calcSalary(get);
}
t.getValue().setSalary(salary);
}
return salary += t.getValue().getSalary();
}
public class Employee {
private SimpleStringProperty name;
private SimpleDoubleProperty salary;
public SimpleStringProperty nameProperty() {
if (name == null) {
name = new SimpleStringProperty(this, "name");
}
return name;
}
public SimpleDoubleProperty salaryProperty() {
if (salary == null) {
salary = new SimpleDoubleProperty(this, "salary");
}
return salary;
}
private Employee(String name, Double salary) {
this.name = new SimpleStringProperty(name);
this.salary = new SimpleDoubleProperty(salary);
}
public String getName() {
return name.get();
}
public void setName(String fName) {
name.set(fName);
}
public Double getSalary() {
return salary.get();
}
public void setSalary(Double fName) {
salary.set(fName);
}
}
}
Is there any way i can use checkboxes for tree item in the above example? I am using JavaFx 8.
I am also try to create Salary Bars, which can also be used as progressbar for a task and its sub tasks. (Just playing with UI). But don't know how to connect them with the real values of employe, as i guess normal table view is different from tree table view. Thanks ! :)
