Detailed Description

A client facing xlib OpenGL base compositor.

Member Function Documentation

◆ client_gl_xlib_compositor_create()

Field Documentation

◆ app_context

struct client_gl_context client_gl_xlib_compositor::app_context

GL context provided in graphics binding.

◆ base

struct client_gl_compositor client_gl_xlib_compositor::base

OpenGL compositor wrapper base.

Referenced by xrt_compositor_native::xrt_gfx_provider_create_gl_xlib().

◆ temp_context

struct client_gl_context client_gl_xlib_compositor::temp_context

Temporary storage for "current" OpenGL context while app_context is made current using context_begin/context_end.

We only need one because app_context can only be made current in one thread at a time too.
