static void Gdk::GL::Drawable::add_interface (  GType  gtype_implementer  )  [static]

static void Gdk::GL::Drawable::draw_cone (  bool  solid, double  base, double  height, int  slices, int  stacks )  [static]

Renders a cone oriented along the Z axis. The base of the cone is placed at Z = 0, and the top at Z = height . The cone is subdivided around the Z axis into slices , and along the Z axis into stacks . Parameters: solid  true if the cone should be solid. base  The radius of the base of the cone. height  The height of the cone. slices  The number of subdivisions around the Z axis. stacks  The number of subdivisions along the Z axis.

static void Gdk::GL::Drawable::draw_cube (  bool  solid, double  size )  [static]

Renders a cube. The cube is centered at the modeling coordinates origin with sides of length size . Parameters: solid  true if the cube should be solid. size  Length of cube sides.

static void Gdk::GL::Drawable::draw_dodecahedron (  bool  solid  )  [static]

Renders a dodecahedron centered at the modeling coordinates origin with a radius of the square root of 3. Parameters: solid  true if the dodecahedron should be solid.

static void Gdk::GL::Drawable::draw_icosahedron (  bool  solid  )  [static]

Renders a icosahedron. The icosahedron is centered at the modeling coordinates origin and has a radius of 1.0. Parameters: solid  true if the icosahedron should be solid.

static void Gdk::GL::Drawable::draw_octahedron (  bool  solid  )  [static]

Renders a octahedron centered at the modeling coordinates origin with a radius of 1.0. Parameters: solid  true if the octahedron should be solid.

static void Gdk::GL::Drawable::draw_sphere (  bool  solid, double  radius, int  slices, int  stacks )  [static]

Renders a sphere centered at the modeling coordinates origin of the specified radius . The sphere is subdivided around the Z axis into slices and along the Z axis into stacks . Parameters: solid  true if the sphere should be solid. radius  The radius of the sphere. slices  The number of subdivisions around the Z axis (similar to lines of longitude). stacks  The number of subdivisions along the Z axis (similar to lines of latitude).

static void Gdk::GL::Drawable::draw_teapot (  bool  solid, double  scale )  [static]

Renders a teapot. Both surface normals and texture coordinates for the teapot are generated. The teapot is generated with OpenGL evaluators. Parameters: solid  true if the teapot should be solid. scale  Relative size of the teapot.

static void Gdk::GL::Drawable::draw_tetrahedron (  bool  solid  )  [static]

Renders a tetrahedron centered at the modeling coordinates origin with a radius of the square root of 3. Parameters: solid  true if the tetrahedron should be solid.

static void Gdk::GL::Drawable::draw_torus (  bool  solid, double  inner_radius, double  outer_radius, int  nsides, int  rings )  [static]

Renders a torus (doughnut) centered at the modeling coordinates origin whose axis is aligned with the Z axis. Parameters: solid  true if the torus should be solid. inner_radius  Inner radius of the torus. outer_radius  Outer radius of the torus. nsides  Number of sides for each radial section. rings  Number of radial divisions for the torus.

static Glib::RefPtr<Drawable> Gdk::GL::Drawable::get_current (   )  [static]

Returns the current Gdk::GLDrawable. Returns: The current Gdk::GLDrawable or 0 if there is no current drawable.

Glib::RefPtr<const Config> Gdk::GL::Drawable::get_gl_config (   )  const

Glib::RefPtr<Config> Gdk::GL::Drawable::get_gl_config (   )

Gets Gdk::GLConfig with which the gldrawable is configured. Returns: The Gdk::GLConfig.

void Gdk::GL::Drawable::get_size (  int &  width, int &  height )

Fills *width and *height with the size of GL drawable. width or height can be 0 if you only want the other one. Parameters: width  Location to store drawable's width, or 0. height  Location to store drawable's height, or 0.

bool Gdk::GL::Drawable::gl_begin (  const Glib::RefPtr< Context > &  glcontext  )

Delimits the begining of the OpenGL execution. Parameters: glcontext  A Gdk::GLContext. Returns: true if it is successful, false otherwise.
