GtkGLArea widget is derived from GtkDrawingArea widget.

examples/simple.c is a good starting point.

C SPECIFICATION

GtkWidget* gtk_gl_area_new(int *attrList)
GtkWidget* gtk_gl_area_share_new(int *attrList, GtkGLArea *share)
GtkWidget* gtk_gl_area_new_vargs(GtkGLArea *share, ...)

PARAMETERS

attrList
	Specifies a list of Boolean attributes and enum/integer
	attribute/value pairs. The last attribute must be zero or
	GDK_GL_NONE.

share
	Specifies the widget with which to share display lists and
	texture objects. NULL indicates that no sharing is to take
	place.

DESCRIPTION
	Make an OpenGL widget, attrList is passed to glXChooseVisual
	GLX call. See glXChooseVisual man page for explanation of
	attrList. Widget is created with visual and colormap of the
	requested type and GLX context is created for this widget. You
	can't do opengl calls on widget until it has X window. X window
	is not created until widget is realized.
	gtk_gl_area_new_vargs takes attrList as variable arguments,
	last argument must still be zero.

---------------------------------------------------------

C SPECIFICATION

gint gtk_gl_area_make_current(GtkGLArea *gl_area)

PARAMETERS

gl_area
	Specifies a gtkglarea widget.

DESCRIPTION
	gtk_gl_area_make_current must be called before rendering into
	OpenGL widget, it returns TRUE if rendering to widget is
	possible. Rendering is not possible if widget is not
	GtkGLArea widget or widget is not realized.

---------------------------------------------------------


C SPECIFICATION

gint gtk_gl_area_begingl(GtkGLArea *gl_area)
void gtk_gl_area_endgl(GtkGLArea *gl_area)

PARAMETERS

gl_area
	Specifies a gtkglarea widget.

DESCRIPTION
	*** Deprecated, use gtk_gl_area_make_current instead ***
	gtk_gl_area_begingl must be called before rendering into
	OpenGL widget, it returns TRUE if rendering to widget is
	possible. Rendering is not possible if widget is not
	GtkGLArea widget or widget is not realized. gtk_gl_area_endgl
	is called to end opengl rendering.




---------------------------------------------------------

C SPECIFICATION
void gtk_gl_area_swap_buffers(GtkGLArea *gl_area)
void gtk_gl_area_swapbuffers(GtkGLArea *gl_area)

PARAMETERS

gl_area
	Specifies a GtkGLArea widget.

DESCRIPTION
	*** gtk_gl_area_swapbuffers is deprecated (wrong spelling), use
	gtk_gl_area_swap_buffers ***
	Wrapper around gdk_gl_swap_buffers. Promotes contents of back buffer
	of widget to front buffer. The contents of front buffer become
	undefined.
