Member Function Documentation

Glib::RefPtr<Gdk::GL::Drawable> Gdk::GL::PixmapExtProxy::get_gl_drawable (   )  const
 

Returns the Gdk::GL::Drawable held by the Gdk::Pixmap .

Returns:
The Gdk::GL::Drawable.

Glib::RefPtr<Pixmap> Gdk::GL::PixmapExtProxy::get_gl_pixmap (   )  const
 

Returns the Gdk::GL::Pixmap held by the Gdk::Pixmap .

Returns:
The Gdk::GL::Pixmap.

bool Gdk::GL::PixmapExtProxy::is_gl_capable (   )  const
 

Returns whether the Gdk::Pixmap is OpenGL-capable.

Returns:
true if the Gdk::Pixmap is OpenGL-capable, false otherwise.

Glib::RefPtr<Pixmap> Gdk::GL::PixmapExtProxy::set_gl_capability (  const Glib::RefPtr< const Config > &  glconfig,
const int *  attrib_list = 0
) 
 

Set the OpenGL-capability to the Gdk::Pixmap. This function creates a new Gdk::GL::Pixmap held by the Gdk::Pixmap. attrib_list is currently unused. This must be set to 0 or empty (first attribute of None).

Parameters:
glconfig A Gdk::GL::Config.
attrib_list This must be set to 0 or empty (first attribute of None).
Returns:
The Gdk::GL::Pixmap used by the Gdk::Pixmap if it is successful, 0 otherwise.

void Gdk::GL::PixmapExtProxy::unset_gl_capability (   ) 
 

Unset the OpenGL-capability of the Gdk::Pixmap . This function destroys the Gdk::GL::Pixmap held by the Gdk::Pixmap.

const PixmapExtProxy ext (  const Glib::RefPtr< const Gdk::Pixmap > &  pixmap  )  [friend]
 

OpenGL extension API wrapper. This is a Gdk::Pixmap wrapper to invoke OpenGL extension function. See Gdk::GL::PixmapExtProxy for available functions.

Parameters:
pixmap A Gdk::Pixmap.

PixmapExtProxy ext (  const Glib::RefPtr< Gdk::Pixmap > &  pixmap  )  [friend]
 

OpenGL extension API wrapper. This is a Gdk::Pixmap wrapper to invoke OpenGL extension function. See Gdk::GL::PixmapExtProxy for available functions.

Here is a simple example: 

 Glib::RefPtr<Gdk::Pixmap> pixmap =
   Gdk::Pixmap::create(0, width, height, glconfig->get_depth());
 Glib::RefPtr<Gdk::GL::Pixmap> glpixmap =
   Gdk::GL::ext(pixmap).set_gl_capability(glconfig);
 std::cout << "OpenGL-capable? "
           << Gdk::GL::ext(pixmap).is_gl_capable()
           << std::endl;

Parameters:
pixmap A Gdk::Pixmap.
