NAME

DESCRIPTION

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.

Boolean ximage

Is False by default, setting it to True will cause Mesa/X to use an Ximage (in contrast to a pixmap) as second buffer.

Boolean shareLists

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.

Boolean shareListsWith

[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

void GLwMakeCurrent (Widget w)

switches the Mesa/X context to the one associated to the widget w.
