How to style the GridPane using CSS in JavaFx

I'm new in JavaFx. I have a GridPane created in FXML. I want to style that GridPane as the following image. I have tried with the following answers and tried with more CSS elements. But none of these helped me to do this.

JavaFX CSS class for GridPane, VBox, VBox

Center children in GridPane using CSS

Adding borders to GridPane JavaFX

And also am I using a wrong approach? Can I achieve this using GridPane or will the TableView is easy to this?

Table Image

Solution

  • I think you can use a TableView control. You can use the following code to start with:

    Controller Class:

    package sample;

import javafx.collections.FXCollections;
import javafx.collections.ObservableList;
import javafx.fxml.FXML;
import javafx.fxml.Initializable;
import javafx.scene.control.TableCell;
import javafx.scene.control.TableColumn;
import javafx.scene.control.TableView;
import javafx.scene.control.cell.PropertyValueFactory;
import javafx.scene.image.Image;
import javafx.scene.image.ImageView;

import java.net.URL;
import java.time.Duration;
import java.time.LocalDate;
import java.time.LocalTime;
import java.time.format.DateTimeFormatter;
import java.util.ResourceBundle;

public class Controller implements Initializable {

    @FXML
    private TableView<Project>
            projectTableView;
    @FXML
    private TableColumn<Project, String>
            projeNameColumn;
    @FXML
    private TableColumn<Project, LocalDate>
            dateColumn;
    @FXML
    private TableColumn<Project, LocalTime>
            startTimeColumn,
            stopTimeColumn;
    @FXML
    private TableColumn<Project, Duration>
            durationColumn;

    private ObservableList<Project> projectList = FXCollections.observableArrayList();

    @Override
    public void initialize(URL location, ResourceBundle resources) {

        projectList.addAll(
                new Project("Landing page Design",
                        LocalDate.of(2019, 5, 21),
                        LocalTime.of(13, 10),
                        LocalTime.of(21, 20, 37)),
                new Project("Mobile App",
                        LocalDate.of(2019, 5, 21),
                        LocalTime.of(12, 0),
                        LocalTime.of(20, 0)),
                new Project("UI/UX",
                        LocalDate.of(2019, 5, 21),
                        LocalTime.of(13, 10),
                        LocalTime.of(13, 20, 37)),
                new Project("Website/apps",
                        LocalDate.of(2019, 5, 21),
                        LocalTime.of(13, 11),
                        LocalTime.of(21, 0, 37)),
                new Project("Branding",
                        LocalDate.of(2019, 5, 21),
                        LocalTime.of(13, 10),
                        LocalTime.of(13, 20, 37))
        );

        projectTableView.setItems(projectList);

        projeNameColumn.setCellValueFactory(new PropertyValueFactory<>("name"));
        projeNameColumn.setCellFactory(tc -> {
            final Image image = new Image(getClass().getResource("image.png").toString());
            return new TableCell<Project, String>() {
                private ImageView imageView = new ImageView();

                @Override
                protected void updateItem(String item, boolean empty) {

                        setGraphic(null);
                    else {
                        imageView.setImage(image);
                        imageView.setPreserveRatio(true);
                        imageView.setFitHeight(35);
                        setGraphic(imageView);
                        setText(item);
                    }
                }
            };
        });

        dateColumn.setCellValueFactory(new PropertyValueFactory("date"));
        dateColumn.setCellFactory((TableColumn<Project, LocalDate> column) -> new TableCell<Project, LocalDate>() {
            protected void updateItem(LocalDate item, boolean empty) {
                super.updateItem(item, empty);
                if (item == null || empty)
                    setText(null);
                else
                    setText(DateTimeFormatter.ofPattern("MMM dd, yyyy").format(item));
            }
        });

        startTimeColumn.setCellValueFactory(new PropertyValueFactory("startTime"));
        startTimeColumn.setCellFactory((TableColumn<Project, LocalTime> column) -> new TableCell<Project, LocalTime>() {
            protected void updateItem(LocalTime item, boolean empty) {
                super.updateItem(item, empty);
                if (item == null || empty)
                    setText(null);
                else
                    setText(DateTimeFormatter.ofPattern("hh:mm a").format(item));
            }
        });

        stopTimeColumn.setCellValueFactory(new PropertyValueFactory("stopTime"));
        stopTimeColumn.setCellFactory((TableColumn<Project, LocalTime> column) -> new TableCell<Project, LocalTime>() {
