Detailed Description

A container of views.

A view manager handles several adaptive views. It can update all the views at the same time. All it needs is the events that come from the window.

Here is a full example with two adaptive views:

  gf::ViewContainer views;

  gf::ExtendView extendView;
  extendView.setSize(ViewSize);
  views.addView(extendView);

  gf::ScreenView screenView;
  views.addView(screenView);

  // initialize the views with the initial screen size
  views.setInitialFramebufferSize(ScreenSize);

  // ...

  while (window.isOpen()) {
    gf::Event event;

    while (window.pollEvent(event)) {
      // ...

      views.processEvent(event);
    }

    // ...

    renderer.clear();

    renderer.setView(extendView);
    renderer.draw(sprite);

    renderer.setView(screenView);
    renderer.draw(ui);

    renderer.display();
  }
