C# Class OpenTK.GLControl

OpenGL-aware WinForms control. The WinForms designer will always call the default constructor. Inherit from this class and call one of its specialized constructors to enable antialiasing or custom GraphicsModes.

Inheritance: System.Windows.Forms.UserControl

Public Methods

Method	Description
GLControl ( OpenTK.Graphics.GraphicsMode mode ) : System	Constructs a new GLControl with the specified GraphicsMode.
GLControl ( OpenTK.Graphics.GraphicsMode mode, int major, int minor, GraphicsContextFlags flags ) : System	Constructs a new GLControl with the specified GraphicsMode.
GetEglDisplay ( ) : IntPtr
GetEglSurface ( ) : IntPtr
MakeCurrent ( ) : void	Makes the underlying this GLControl current in the calling thread. All OpenGL commands issued are hereafter interpreted by this GLControl.
SwapBuffers ( ) : void	Swaps the front and back buffers, presenting the rendered scene to the screen.
