Methods
glDrawableMakeCurrent
:: GLDrawableClass self
=> self
-> GLContext
-> IO Boolreturns True if it is successful, False otherwise.
Attach an OpenGL rendering context to a GL drawable.
glDrawableIsDoubleBuffered
:: GLDrawableClass self
=> self
-> IO Boolreturns True if the double-buffered visual is supported, False otherwise.
Returns whether the GL drawable supports the double-buffered visual.
glDrawableSwapBuffers :: GLDrawableClass self => self -> IO ()
Exchange front and back buffers.
glDrawableWaitGL :: GLDrawableClass self => self -> IO ()
Complete OpenGL execution prior to subsequent Gdk drawing calls.
glDrawableWaitGdk :: GLDrawableClass self => self -> IO ()
Complete Gdk drawing execution prior to subsequent OpenGL calls.
glDrawableGLBegin
:: GLDrawableClass self
=> self
-> GLContextglcontext - a GLContext.
-> IO Boolreturns True if it is successful, False otherwise.
Delimits the begining of the OpenGL execution.
glDrawableGLEnd :: GLDrawableClass self => self -> IO ()
Delimits the end of the OpenGL execution.
glDrawableGetGLConfig :: GLDrawableClass self => self -> IO GLConfig
Gets GLConfig with which the GL drawable is configured.
glDrawableGetSize
:: GLDrawableClass self
=> self
-> IO (Int, Int)
(width, height)
Returns the width and height of the GL drawable.
glDrawableGetCurrent
:: IO (Maybe GLDrawable)returns the current Drawable or Nothing if there is no current drawable.
Returns the current GLDrawable.
