TGX11TTF Class Reference

Interface to low level X11 (Xlib).

This class gives access to basic X11 graphics via the parent class TGX11. However, all text and font handling is done via the Freetype TrueType library. When the shared library containing this class is loaded the global gVirtualX is redirected to point to this class.
