A Gdk::GLContext is an OpenGL context abstraction.
It's a low-level object, used to implement high-level objects such as Gtk::GLArea on the GTK+ level.

Clears the current Gdk::GLContext.
Any OpenGL call after this function returns will be ignored until gdk_gl_context_make_current() is called.

Retrieves the current Gdk::GLContext.
nullptr
. bool Gdk::GLContext::get_debug_enabled | ( | ) | const |

nullptr
. bool Gdk::GLContext::get_forward_compatible | ( | ) | const |
Retrieves the value set using gdk_gl_context_set_forward_compatible().
true
if the context should be forward compatible. void Gdk::GLContext::get_required_version | ( | int & | major, |
int & | minor | ||
) | const |
Retrieves the major and minor version requested by calling gdk_gl_context_set_required_version().
major | Return location for the major version to request. |
minor | Return location for the minor version to request. |

Get the GType for this class, for use with the underlying GObject type system.
void Gdk::GLContext::get_version | ( | int & | major, |
int & | minor | ||
) | const |
Retrieves the OpenGL version of the context.
The context must be realized prior to calling this function.
major | Return location for the major version. |
minor | Return location for the minor version. |

GdkGLContext* Gdk::GLContext::gobj_copy | ( | ) |
Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.

The Gdk::Window the gl context is bound to.
bool Gdk::GLContext::realize | ( | ) |
Realizes the given Gdk::GLContext.
It is safe to call this function on a realized Gdk::GLContext.
true
if the context is realized. void Gdk::GLContext::set_debug_enabled | ( | bool | enabled = true | ) |
Sets whether the Gdk::GLContext should perform extra validations and run time checking.
This is useful during development, but has additional overhead.
The Gdk::GLContext must not be realized or made current prior to calling this function.
enabled | Whether to enable debugging in the context. |
void Gdk::GLContext::set_forward_compatible | ( | bool | compatible = true | ) |
Sets whether the Gdk::GLContext should be forward compatible.
Forward compatibile contexts must not support OpenGL functionality that has been marked as deprecated in the requested version; non-forward compatible contexts, on the other hand, must support both deprecated and non deprecated functionality.
The Gdk::GLContext must not be realized or made current prior to calling this function.
compatible | Whether the context should be forward compatible. |
void Gdk::GLContext::set_required_version | ( | int | major, |
int | minor | ||
) |
Sets the major and minor version of OpenGL to request.
Setting major and minor to zero will use the default values.
The Gdk::GLContext must not be realized or made current prior to calling this function.
major | The major version to request. |
minor | The minor version to request. |
