glXCreateWindow

Name

glXCreateWindow — create an on-screen rendering area

C Specification

`GLXWindow glXCreateWindow(`	Display *	`dpy`,
	GLXFBConfig	`config`,
	Window	`win`,
	const int *	`attrib_list)`;

Parameters

dpy: Specifies the connection to the X server.
config: Specifies a GLXFBConfig structure with the desired attributes for the window.
win: Specifies the X window to be used as the rendering area.
attrib_list: Currently unused. This must be set to NULL or be an empty list (i.e., one in which the first element is None).

Description

glXCreateWindow creates an on-screen rendering area from an existing X window that was created with a visual matching config. The XID of the GLXWindow is returned. Any GLX rendering context that was created with respect to config can be used to render into this window. Use glXMakeContextCurrent to associate the rendering area with a GLX rendering context.

Notes

glXCreateWindow is available only if the GLX version is 1.3 or greater.

If the GLX version is 1.1 or 1.0, the GL version must be 1.0. If the GLX version is 1.2, then the GL version must be 1.1. If the GLX version is 1.3, then the GL version must be 1.2.

Errors

BadMatch is generated if win was not created with a visual that corresponds to config.

BadMatch is generated if config does not support rendering to windows (i.e., GLX_DRAWABLE_TYPE does not contain GLX_WINDOW_BIT).

BadWindow is generated if win is not a valid pixmap XID.

BadAlloc is generated if there is already a GLXFBConfig associated with win.

BadAlloc is generated if the X server cannot allocate a new GLX window.

GLXBadFBConfig is generated if config is not a valid GLXFBConfig.
