/* SFML::Window is the main class of the Window module.
|
|
*
|
|
* It defines an OS window that is able to receive an OpenGL rendering.
|
|
*
|
|
* A SFML::Window can create its own new window, or be embedded into an already existing control using the Create(handle)
|
|
* function. This can be useful for embedding an OpenGL rendering area into a view which is part of a bigger GUI with
|
|
* existing windows, controls, etc. It can also serve as embedding an OpenGL rendering area into a window created by
|
|
* another (probably richer) GUI library like Qt or wxWidgets.
|
|
*
|
|
* The SFML::Window class provides a simple interface for manipulating the window: move, resize, show/hide, control mouse
|
|
* cursor, etc. It also provides event handling through its getEvent() function, and real-time state handling with its
|
|
* attached SFML::Input object (see getInput()).
|
|
*
|
|
* Note that OpenGL experts can pass their own parameters (antialiasing level, bits for the depth and stencil buffers,
|
|
* etc.) to the OpenGL context attached to the window, with the SFML::ContextSettings structure which is passed as an
|
|
* optional argument when creating the window.
|
|
*
|
|
* Usage example:
|
|
*
|
|
* # Declare and create a new window
|
|
* window = SFML::Window.new( SFML::VideoMode.new( 800, 600 ), "SFML window" )
|
|
*
|
|
* # Limit the framerate to 60 frames per second (this step is optional)
|
|
* window.setFramerateLimit( 60 );
|
|
*
|
|
* # The main loop - ends as soon as the window is closed
|
|
* while window.open?
|
|
*
|
|
* # Event processing
|
|
* while event = window.getEvent
|
|
*
|
|
* # Request for closing the window
|
|
* if event.type == SFML::Event::Closed
|
|
* window.close()
|
|
* end
|
|
* end
|
|
*
|
|
* # Activate the window for OpenGL rendering
|
|
* window.setActive()
|
|
*
|
|
* # OpenGL drawing commands go here...
|
|
*
|
|
* # End the current frame and display its contents on screen
|
|
* window.display()
|
|
* end
|
