Creates an off-screen rendering area.
attrib_list is currently unused. This must be set to NULL or empty
(first attribute of None). See GLX 1.3 spec.glconfig : a GdkGLConfig.
pixmap : the GdkPixmap to be used as the rendering area.
attrib_list : this must be set to NULL or empty (first attribute of None).
Returns : the new GdkGLPixmap.
<anchor id="gdk-gl-pixmap-destroy"/>gdk_gl_pixmap_destroy ()gdk_gl_pixmap_destroyvoid gdk_gl_pixmap_destroy (GdkGLPixmap *glpixmap);
Destroys the OpenGL resources associated with glpixmap and
decrements glpixmap's reference count.glpixmap : a GdkGLPixmap.
<anchor id="gdk-gl-pixmap-get-pixmap"/>gdk_gl_pixmap_get_pixmap ()gdk_gl_pixmap_get_pixmapGdkPixmap* gdk_gl_pixmap_get_pixmap (GdkGLPixmap *glpixmap);
Returns the GdkPixmap associated with glpixmap.
Notice that GdkGLPixmap is not GdkPixmap, but another
GdkDrawable which have an associated GdkPixmap.glpixmap : a GdkGLPixmap.
Returns : the GdkPixmap associated with glpixmap.
<anchor id="gdk-pixmap-set-gl-capability"/>gdk_pixmap_set_gl_capability ()gdk_pixmap_set_gl_capabilityGdkGLPixmap* gdk_pixmap_set_gl_capability (GdkPixmap *pixmap,
GdkGLConfig *glconfig,
const int *attrib_list);
Set the OpenGL-capability to the pixmap.
This function creates a new GdkGLPixmap held by the pixmap.
attrib_list is currently unused. This must be set to NULL or empty
(first attribute of None).pixmap : the GdkPixmap to be used as the rendering area.
glconfig : a GdkGLConfig.
attrib_list : this must be set to NULL or empty (first attribute of None).
Returns : the GdkGLPixmap used by the pixmap if it is successful,
NULL otherwise.
<anchor id="gdk-pixmap-unset-gl-capability"/>gdk_pixmap_unset_gl_capability ()gdk_pixmap_unset_gl_capabilityvoid gdk_pixmap_unset_gl_capability (GdkPixmap *pixmap);
Unset the OpenGL-capability of the pixmap.
This function destroys the GdkGLPixmap held by the pixmap.pixmap : a GdkPixmap.
<anchor id="gdk-pixmap-is-gl-capable"/>gdk_pixmap_is_gl_capable ()gdk_pixmap_is_gl_capablegboolean gdk_pixmap_is_gl_capable (GdkPixmap *pixmap);
Returns whether the pixmap is OpenGL-capable.pixmap : a GdkPixmap.
Returns : TRUE if the pixmap is OpenGL-capable, FALSE otherwise.
<anchor id="gdk-pixmap-get-gl-pixmap"/>gdk_pixmap_get_gl_pixmap ()gdk_pixmap_get_gl_pixmapGdkGLPixmap* gdk_pixmap_get_gl_pixmap (GdkPixmap *pixmap);
Returns the GdkGLPixmap held by the pixmap.pixmap : a GdkPixmap.
Returns : the GdkGLPixmap.
<anchor id="gdk-pixmap-get-gl-drawable"/>gdk_pixmap_get_gl_drawable()gdk_pixmap_get_gl_drawable#define gdk_pixmap_get_gl_drawable(pixmap)
Returns the GdkGLDrawable held by the pixmap. In fact, this is macro
that casts the result of gdk_pixmap_get_gl_pixmap to GdkGLDrawable.
pixmap :a GdkGLPixmap.
Returns :the GdkGLDrawable.
