Time for action – the main layout

Let's start by coding the main layout using our well known friend VerticalLayout and the new guy HorizontalLayout:

  1. Create a new Vaadin project. For this example, we will use layout-framework as project name and LayoutFrameworkUI as the UI class.

  2. Create a new Java class MainLayout.

  3. Let MainLayout extend VerticalLayout:

    public class MainLayout extends VerticalLayout {
  4. Add layouts for upper and lower sections of MainLayout:

    public class MainLayout extends VerticalLayout {
      private VerticalLayout upperSection = new VerticalLayout();
      private HorizontalLayout lowerSection = new     HorizontalLayout();
      private VerticalLayout menuLayout = new VerticalLayout();
      private VerticalLayout contentLayout = new VerticalLayout();
  5. Add the following default constructor for MainLayout:

    public MainLayout() {
      upperSection.addComponent(new Label("Header"));
      menuSection.addComponent(new Label("Menu"));
      contentSection.addComponent(new Label("Content"));
