Detailed Description

The interface for windowing toolkits.

This class is intended to be overwritten by an (anonymous) class with exactly one static instance. The constructor will register this factory instance for use with the WindowSystem frontend. See glx/windowSystem.cpp for an example.

The implementation provides access to operating system dependent functionality needed by Equalizer, and hides these specifics behind interfaces.

const uint32_t  size 
) const
protectedpure virtual

Create a set of display lists for the given font.

The implementation is expected to set up one display list per ASCII character, and store the name of the first list in the given object manager using the given key.

Parameters
glthe object manager for display list allocation.
keythe key for display list allocation.
namethe name of the font, OS-specific.
sizethe font size in points.
Returns
true if the font was created, false otherwise.
Warning
experimental, might not be supported in the future.
