|  | const Glib::RefPtr< const Context > & | share_list,
|  | bool | direct = `true`,
|  | int | render_type = `RGBA_TYPE`

## 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.

## Friends And Related Function Documentation

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.
