Pointer<Gdk::GL::Context> Inti::Gtk::GL::Widget::create_gl_context (  const Gdk::GL::Context &  share_list, bool  direct = true, int  render_type = GDK_GL_RGBA_TYPE )

Creates a new Gdk::GL::Context with the appropriate Gdk::GL::Drawable for this widget. Parameters: share_list  The Gdk::GL::Context with which to share display lists and texture objects. 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 Context, or null if an error occurs. See also get_gl_context().

Pointer<Gdk::GL::Context> Inti::Gtk::GL::Widget::create_gl_context (  bool  direct = true, int  render_type = GDK_GL_RGBA_TYPE )

Creates a new Gdk::GL::Context with the appropriate Gdk::GL::Drawable for this widget. Parameters: 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 Context, or null if an error occurs. See also get_gl_context().

Gdk::GL::Config* Inti::Gtk::GL::Widget::get_gl_config (   )  const

Gets the Gdk::GL::Config referred to by the widget. Returns: The Gdk::GL::Config.

Gdk::GL::Context* Inti::Gtk::GL::Widget::get_gl_context (   )  const

Gets the Gdk::GL::Context with the appropriate Gdk::GL::Drawable for the widget. Returns: The Gdk::GL::Context. A Gdk::GL::Context is needed for the method Gdk::GL::Drawable::begin, or for sharing display lists (see set_gl_capability()).

Gdk::GL::Drawable* Inti::Gtk::GL::Widget::get_gl_drawable (   )  const

Gets the Gdk::GL::Drawable owned by the widget. Returns: The Gdk::GL::Drawable. This method returns the result of get_gl_window() cast to a Gdk::GL::Drawable.

Gdk::GL::Window* Inti::Gtk::GL::Widget::get_gl_window (   )  const

Gets the Gdk::GL::Window owned by the widget. Returns: The Gdk::GL::Window.

bool Inti::Gtk::GL::Widget::is_gl_capable (   )  const

Determines whether the widget is OpenGL-capable. Returns: true if the widget is OpenGL-capable, false otherwise.

bool Inti::Gtk::GL::Widget::set_gl_capability (  const Gdk::GL::Config &  glconfig, const Gdk::GL::Context &  share_list, bool  direct = true, int  render_type = GDK_GL_RGBA_TYPE )

Sets the OpenGL-capability for the widget. Parameters: glconfig  A Gdk::GL::Config. share_list  The Gdk::GL::Context with which to share display lists and texture objects. 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: true if it is successful, false otherwise. This method prepares the widget for its use with OpenGL.

bool Inti::Gtk::GL::Widget::set_gl_capability (  const Gdk::GL::Config &  glconfig, bool  direct = true, int  render_type = GDK_GL_RGBA_TYPE )

Sets the OpenGL-capability for the widget. Parameters: glconfig  A Gdk::GL::Config. 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: true if it is successful, false otherwise. This method prepares the widget for its use with OpenGL. No sharing of display lists and texture objects takes place when you call this method.
