16/** \class TGX11
17\ingroup x11
18This class is the basic interface to the X11 (Xlib) graphics system.
19It is an implementation of the abstract TVirtualX class.
20
21This class gives access to basic X11 graphics, pixmap, text and font handling
22routines.
23
24The companion class for Win32 is TGWin32.
25
26The file G11Gui.cxx contains the implementation of the GUI methods of the
27TGX11 class. Most of the methods are used by the machine independent
28GUI classes (libGUI.so).
29
30This code was initially developed in the context of HIGZ and PAW
31by Olivier Couet (package X11INT).
