Constructor & Destructor Documentation

Inti::Gdk::GL::Config::Config (  GdkGLConfig *  config, bool  reference = true )  [explicit, protected]

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

Member Function Documentation

Pointer<Config> Inti::Gdk::GL::Config::create (  ConfigModeField  mode, const Gdk::Screen *  screen = 0 )  [static]

Create an OpenGL frame buffer configuration that matches the specified display mode. Parameters: mode  The display mode bit mask. screen  The target screen, or null for the default screen. Returns: A smart pointer to a new Config object, or null if an error occurs.

Pointer<Config> Inti::Gdk::GL::Config::create (  const int *  attrib_list, const Gdk::Screen *  screen = 0 )  [static]

Create an OpenGL frame buffer configuration that matchs the specified attributes. Parameters: attrib_list  An int array that contains the attribute/value pairs. screen  The target screen, or null for the default screen. Returns: A smart pointer to a new Config object, or null if an error occurs. Available attributes are: GDK_GL_USE_GL, GDK_GL_BUFFER_SIZE, GDK_GL_LEVEL, GDK_GL_RGBA, GDK_GL_DOUBLEBUFFER, GDK_GL_STEREO, GDK_GL_AUX_BUFFERS, GDK_GL_RED_SIZE, GDK_GL_GREEN_SIZE, GDK_GL_BLUE_SIZE, GDK_GL_ALPHA_SIZE, GDK_GL_DEPTH_SIZE, GDK_GL_STENCIL_SIZE, GDK_GL_ACCUM_RED_SIZE, GDK_GL_ACCUM_GREEN_SIZE, GDK_GL_ACCUM_BLUE_SIZE, GDK_GL_ACCUM_ALPHA_SIZE. The last attribute in attrib_list must be GDK_GL_ATTRIB_LIST_NONE.

bool Inti::Gdk::GL::Config::get_attrib (  int  attribute, int &  value )

Gets information about an OpenGL frame buffer configuration. Parameters: attribute  The attribute to be returned. value  A reference to the return location for the requested value. Returns: true if successful, false otherwise.

Gdk::Colormap* Inti::Gdk::GL::Config::get_colormap (   )  const

Gets the Gdk::Colormap that is appropriate for the OpenGL frame buffer configuration. Returns: The appropriate Gdk::Colormap.

int Inti::Gdk::GL::Config::get_depth (   )  const

Gets the color depth of the OpenGL-capable visual. Returns: The number of bits per pixel.

int Inti::Gdk::GL::Config::get_layer_plane (   )  const

Gets the layer plane (level) of the frame buffer. Returns: The layer plane. Zero is the default frame buffer. Positive layer planes correspond to frame buffers that overlay the default buffer, and negative layer planes correspond to frame buffers that underlie the default frame buffer.

int Inti::Gdk::GL::Config::get_n_aux_buffers (   )  const

Gets the number of auxiliary color buffers. Returns: The number of auxiliary color buffers.

int Inti::Gdk::GL::Config::get_n_sample_buffers (   )  const

Gets the number of multisample buffers. Returns: The number of multisample buffers.

Gdk::Visual* Inti::Gdk::GL::Config::get_visual (   )  const

Gets the Gdk::Visual that is appropriate for the OpenGL frame buffer configuration. Returns: The appropriate Gdk::Visual.

bool Inti::Gdk::GL::Config::has_accum_buffer (   )  const

Determines whether the configured frame buffer has accumulation buffer. Returns: true if the frame buffer has accumulation buffer, false otherwise.

bool Inti::Gdk::GL::Config::has_alpha (   )  const

Determines whether the configured color buffer has alpha bits. Returns: true if the color buffer has alpha bits, false otherwise.

bool Inti::Gdk::GL::Config::has_depth_buffer (   )  const

Determines whether the configured frame buffer has depth buffer. Returns: true if the frame buffer has depth buffer, false otherwise.

bool Inti::Gdk::GL::Config::has_stencil_buffer (   )  const

Determines whether the configured frame buffer has stencil buffer. Returns: true if the frame buffer has stencil buffer, false otherwise.

bool Inti::Gdk::GL::Config::is_double_buffered (   )  const

Determines whether the configuration supports the double-buffered visual. Returns: true if the double-buffered visual is supported, false otherwise.

bool Inti::Gdk::GL::Config::is_rgba (   )  const

Determines whether the configured frame buffer is RGBA mode. Returns: true if the configured frame buffer is RGBA mode, false otherwise.

bool Inti::Gdk::GL::Config::is_stereo (   )  const

Determines whether the configuration supports the stereo visual. Returns: true if the stereo visual is supported, false otherwise.
