C# Class OpenTK.GameWindow

The GameWindow class contains cross-platform methods to create and render on an OpenGL window, handle input and load resources.

GameWindow contains several events you can hook or override to add your custom logic: OnLoad: Occurs after creating the OpenGL context, but before entering the main loop. Override to load resources. OnUnload: Occurs after exiting the main loop, but before deleting the OpenGL context. Override to unload resources. OnResize: Occurs whenever GameWindow is resized. You should update the OpenGL Viewport and Projection Matrix here. OnUpdateFrame: Occurs at the specified logic update rate. Override to add your game logic. OnRenderFrame: Occurs at the specified frame render rate. Override to add your rendering code. Call the Run() method to start the application's main loop. Run(double, double) takes two parameters that specify the logic update rate, and the render update rate.

Inheritance: NativeWindow, IGameWindow, IDisposable

Méthodes publiques

Méthode	Description
Dispose ( ) : void	Disposes of the GameWindow, releasing all resources consumed by it.
Exit ( ) : void	Closes the GameWindow. Equivalent to NativeWindow.Close method. Override if you are not using GameWindow.Run(). If you override this method, place a call to base.Exit(), to ensure proper OpenTK shutdown.
GameWindow ( ) : System	Constructs a new GameWindow with sensible default attributes.
GameWindow ( int width, int height ) : System	Constructs a new GameWindow with the specified attributes.
GameWindow ( int width, int height, OpenTK.Graphics.GraphicsMode mode ) : System	Constructs a new GameWindow with the specified attributes.
GameWindow ( int width, int height, OpenTK.Graphics.GraphicsMode mode, string title ) : System	Constructs a new GameWindow with the specified attributes.
GameWindow ( int width, int height, OpenTK.Graphics.GraphicsMode mode, string title, GameWindowFlags options ) : System	Constructs a new GameWindow with the specified attributes.
GameWindow ( int width, int height, OpenTK.Graphics.GraphicsMode mode, string title, GameWindowFlags options, DisplayDevice device ) : System	Constructs a new GameWindow with the specified attributes.
GameWindow ( int width, int height, OpenTK.Graphics.GraphicsMode mode, string title, GameWindowFlags options, DisplayDevice device, int major, int minor, GraphicsContextFlags flags ) : System	Constructs a new GameWindow with the specified attributes.
GameWindow ( int width, int height, OpenTK.Graphics.GraphicsMode mode, string title, GameWindowFlags options, DisplayDevice device, int major, int minor, GraphicsContextFlags flags, IGraphicsContext sharedContext ) : System	Constructs a new GameWindow with the specified attributes.
MakeCurrent ( ) : void	Makes the GraphicsContext current on the calling thread.
Run ( ) : void	Enters the game loop of the GameWindow using the maximum update rate.
Run ( double updateRate ) : void	Enters the game loop of the GameWindow using the specified update rate. maximum possible render frequency.
Run ( double updates_per_second, double frames_per_second ) : void	Enters the game loop of the GameWindow updating and rendering at the specified frequency. When overriding the default game loop you should call ProcessEvents() to ensure that your GameWindow responds to operating system events. Once ProcessEvents() returns, it is time to call update and render the next frame.
SwapBuffers ( ) : void	Swaps the front and back buffer, presenting the rendered scene to the user.

Méthodes protégées

Méthode	Description
Dispose ( bool manual ) : void	Override to add custom cleanup logic.
OnClosing ( System e ) : void	Called when the NativeWindow is about to close.
OnLoad ( EventArgs e ) : void	Called after an OpenGL context has been established, but before entering the main loop.
OnRenderFrame ( FrameEventArgs e ) : void	Called when the frame is rendered. Subscribe to the RenderFrame event instead of overriding this method.
OnResize ( EventArgs e ) : void	Called when this window is resized. You will typically wish to update your viewport whenever the window is resized. See the OpenTK.Graphics.OpenGL.GL.Viewport(int, int, int, int) method.
OnUnload ( EventArgs e ) : void	Called after GameWindow.Exit was called, but before destroying the OpenGL context.
OnUpdateFrame ( FrameEventArgs e ) : void	Called when the frame is updated. Subscribe to the UpdateFrame event instead of overriding this method.
OnWindowInfoChanged ( EventArgs e ) : void	Called when the WindowInfo for this GameWindow has changed.

Method Details

Dispose() public méthode

Disposes of the GameWindow, releasing all resources consumed by it.

public Dispose ( ) : void
Résultat	void

Dispose() protected méthode

Override to add custom cleanup logic.

protected Dispose ( bool manual ) : void
manual	bool	True, if this method was called by the application; false if this was called by the finalizer thread.
Résultat	void

Exit() public méthode

Closes the GameWindow. Equivalent to NativeWindow.Close method.

Override if you are not using GameWindow.Run().

If you override this method, place a call to base.Exit(), to ensure proper OpenTK shutdown.
