Creates a new OpenGL rendering context.gldrawable : a GdkGLDrawable.
share_list : the GdkGLContext with which to share display lists and texture
objects. NULL indicates that no sharing is to take place.
direct : whether rendering is to be done with a direct connection to
the graphics system.
render_type : GDK_GL_RGBA_TYPE or GDK_GL_COLOR_INDEX_TYPE (currently not
used).
Returns : the new GdkGLContext.
<anchor id="gdk-gl-context-destroy"/>gdk_gl_context_destroy ()gdk_gl_context_destroyvoid gdk_gl_context_destroy (GdkGLContext *glcontext);
Destroys the OpenGL resources associated with glcontext and
decrements glcontext's reference count.glcontext : a GdkGLContext.

GdkGLContext *src,
unsigned long mask);
Copy state from src rendering context to glcontext.
mask contains the bitwise-OR of the same symbolic names that are passed to
the glPushAttrib() function. You can use GL_ALL_ATTRIB_BITS to copy all the
rendering state information.glcontext : a GdkGLContext.
src : the source context.
Param3 :Returns : FALSE if it fails, TRUE otherwise.

(GdkGLContext *glcontext);
Gets GdkGLDrawable to which the glcontext is bound.glcontext : a GdkGLContext.
Returns : the GdkGLDrawable or NULL if no GdkGLDrawable is bound.

Gets GdkGLConfig with which the glcontext is configured.glcontext : a GdkGLContext.
Returns : the GdkGLConfig.

Gets GdkGLContext with which the glcontext shares the display lists and
texture objects.glcontext : a GdkGLContext.
Returns : the GdkGLContext.
<anchor id="gdk-gl-context-is-direct"/>gdk_gl_context_is_direct ()gdk_gl_context_is_directgboolean gdk_gl_context_is_direct (GdkGLContext *glcontext);
Returns whether the glcontext is a direct rendering context.glcontext : a GdkGLContext.
Returns : TRUE if the glcontext is a direct rendering contest.

Gets render_type of the glcontext.glcontext : a GdkGLContext.
Returns : GDK_GL_RGBA_TYPE or GDK_GL_COLOR_INDEX_TYPE.
<anchor id="gdk-gl-context-get-current"/>gdk_gl_context_get_current ()gdk_gl_context_get_currentGdkGLContext* gdk_gl_context_get_current (void);
Returns the current GdkGLContext.Returns : the current GdkGLContext or NULL if there is no current
context.
