Detailed Description

This section of the API is concerned with all of the Objects used for creating, visualising and interacting with a user interface.

Everything hangs off the Q::Screen, which on desktop systems is effectively the window and on consoles is the display. Then a number of different layers can be added to the screen. These are effectively just rectangles that get drawn into in various ways:

• ImageLayer for straight 2D images.
• CameraLayer for rendering a 3D scene into.
• TextLayer for rendering a given string in a given font into.
• StatsLayer for displaying various performance counters.
• LogLayer for displaying error messages.

Then the layers can be individually configured to receive mouse and keyboard events, depending on which layer is in focus.
