Member Function Documentation

bool Gdk::GL::Context::copy (  const Glib::RefPtr< const Context > &  src, unsigned long  mask = GL_ALL_ATTRIB_BITS )

Copy state from one rendering context to another. mask contains the bitwise-OR of the same symbolic names that are passed to the glPushAttrib() function. You can use GL_ALL_ATTRIB_BITS to copy all the rendering state information. Parameters: src  the source context. mask  which portions of src state are to be copied. Returns: false if it fails, true otherwise.

static Glib::RefPtr<Context> Gdk::GL::Context::create (  const Glib::RefPtr< const Drawable > &  gldrawable, bool  direct = true, int  render_type = RGBA_TYPE )  [static]

Create a new OpenGL rendering context. Parameters: gldrawable  a Gdk::GL::Drawable. 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 Gdk::GL::Context.

static Glib::RefPtr<Context> Gdk::GL::Context::create (  const Glib::RefPtr< const Drawable > &  gldrawable, const Glib::RefPtr< const Context > &  share_list, bool  direct = true, int  render_type = RGBA_TYPE )  [static]

Create a new OpenGL rendering context. Parameters: gldrawable  a Gdk::GL::Drawable. share_list  the Gdk::GL::Context which to share display lists. 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 Gdk::GL::Context. Examples: pixmap-mixed.cc, and pixmap.cc.

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

Returns the current Gdk::GLContext. Returns: The current Gdk::GLContext or 0 if there is no current context.

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

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

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

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

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

Gets Gdk::GLDrawable to which the glcontext is bound. Returns: The Gdk::GLDrawable or 0 if no Gdk::GLDrawable is bound.

Glib::RefPtr<Drawable> Gdk::GL::Context::get_gl_drawable (   )

Gets Gdk::GLDrawable to which the glcontext is bound. Returns: The Gdk::GLDrawable or 0 if no Gdk::GLDrawable is bound.

int Gdk::GL::Context::get_render_type (   )  const

Gets render_type of the glcontext . Returns: GDK_GL_RGBA_TYPE or GDK_GL_COLOR_INDEX_TYPE.

Glib::RefPtr<const Context> Gdk::GL::Context::get_share_list (   )  const

Gets Gdk::GLContext with which the glcontext shares the display lists and texture objects. Returns: The Gdk::GLContext.

Glib::RefPtr<Context> Gdk::GL::Context::get_share_list (   )

Gets Gdk::GLContext with which the glcontext shares the display lists and texture objects. Returns: The Gdk::GLContext.

const GdkGLContext* Gdk::GL::Context::gobj (   )  const [inline]

Provides access to the underlying C GObject.

GdkGLContext* Gdk::GL::Context::gobj (   )  [inline]

Provides access to the underlying C GObject.

GdkGLContext* Gdk::GL::Context::gobj_copy (   )

Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.

bool Gdk::GL::Context::is_direct (   )  const

Returns whether the glcontext is a direct rendering context. Returns: true if the glcontext is a direct rendering contest.

Glib::RefPtr< Gdk::GL::Context > wrap (  GdkGLContext *  object, bool  take_copy = false )  [related]

Parameters: object  The C instance take_copy  False if the result should take ownership of the C instance. True if it should take a new copy or ref. Returns: A C++ instance that wraps this C instance.
