Accessors

• GdkGLContext * gdk_gl_context () const

  Get a pointer to the GdkGLContext structure.
  
  

• GdkGLContextClass * gdk_gl_context_class () const

  Get a pointer to the GdkGLContextClass structure.

• int get_render_type () const

  Gets render_type of the context.
  
  

Methods

• virtual void dispose ()

  Disposes of the OpenGL resources associated with the context and decrements context's reference count.
  
  

• bool copy (const Context &src, unsigned long mask=GL_ALL_ATTRIB_BITS)

  Copy one or more state bits from src to this context.

Constructor & Destructor Documentation

Inti::Gdk::GL::Context::Context (  GdkGLContext *  context, bool  reference = true )  [explicit, protected]

Construct a new Context from an existing GdkGLContext. Parameters: context  A pointer to a GdkGLContext. reference  Set false if the initial reference count is floating, set true if it's not. The context can be a newly created GdkGLContext or an existing GdkGLContext. (see G::Object::Object).

Member Function Documentation

bool Inti::Gdk::GL::Context::copy (  const Context &  src, unsigned long  mask = GL_ALL_ATTRIB_BITS )

Copy one or more state bits from src to this context. Parameters: src  The source context. mask  The bitwise-OR of the same symbolic names that are passed to glPushAttrib(). Returns: true if successful, false otherwise. You can use GL_ALL_ATTRIB_BITS to copy all the rendering state information (see the "GL/gl.h" header file).

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

Creates a new OpenGL rendering context. Parameters: gldrawable  A Gdk::GL::Drawable. share_list  The 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.

Pointer<Context> Inti::Gdk::GL::Context::create (  const Drawable &  gldrawable, bool  direct = true, int  render_type = GDK_GL_RGBA_TYPE )  [static]

Creates 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 Context, or null if an error occurs. No context sharing takes place with contexts created by this method.

Context* Inti::Gdk::GL::Context::get_current (   )  [static]

Gets the current Gdk::GL::Context. Returns: The current Gdk::GL::Context, or null if there is no current context.

Config* Inti::Gdk::GL::Context::get_gl_config (   )  const

Gets Gdk::GL::Config with which the context is configured. Returns: A pointer to the Gdk::GL::Config object.

Drawable* Inti::Gdk::GL::Context::get_gl_drawable (   )  const

Gets Gdk::GL::Drawable to which the context is bound. Returns: The drawable, or null if no Gdk::GL::Drawable is bound.

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

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

Context* Inti::Gdk::GL::Context::get_share_list (   )  const

Gets the Gdk::GL::Context with which the context shares the display lists and texture objects. Returns: The Gdk::GL::Context, or null if the context is not sharing.

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

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