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({ 1000.0f, 1000.0f });
views.addView(extendView);

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

// initialize the views with the initial screen size
views.onScreenResize(screenSize);

// ...

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

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

    views.update(event);
  }

  // ...

  renderer.clear();

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

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

  renderer.display();
}
