MESADRAWINGAREA(1)

NAME
MesaDrawingArea - An Xt widget for Mesa/X with richer semantics

DESCRIPTION
The MesaDrawingArea widget is an extension of the GLwDrawingArea widget which takes advantage of some features of the Mesa/X implementation of the OpenGL API.

It also simplifies programming by associating a drawing context transparently to the widget. This feature is particulary convenient in applications that have to deal with multiple instances of a MesaDrawingArea widget.

Resources
The following X resources are available in addition to the GLwDrawingArea resources:

Is False by default, setting it to True will cause Mesa/X to use an Ximage (in contrast to a pixmap) as second buffer. Is False by default, setting it to True will cause Mesa/X to share display lists among all widgets that have this ressource set to True. [Caveat: This resource is not honored yet.]

Is NULL by default, setting it to another MesaDrawingArea widget will cause the two widgets to share display lists.

Utility functions
The following utility functions are available switches the Mesa/X context to the one associated to the widget w.
