Method

GdkGLContextset_use_es

Declaration [src]

void
gdk_gl_context_set_use_es (
  GdkGLContext* context,
  int use_es
)

Description [src]

Requests that GDK create a OpenGL ES context instead of an OpenGL one, if the platform and windowing system allows it.

The context must not have been realized.

By default, GDK will attempt to automatically detect whether the underlying GL implementation is OpenGL or OpenGL ES once the context is realized.

You should check the return value of gdk_gl_context_get_use_es() after calling gdk_gl_context_realize() to decide whether to use the OpenGL or OpenGL ES API, extensions, or shaders.

Available since:3.22

Parameters

use_es int
 

Whether the context should use OpenGL ES instead of OpenGL, or -1 to allow auto-detection.
