                 Simple examples.
 --------------------------------------------------------

demo1.py -- Hello, world !!!

demo2.py -- Cursor Selection.

demo3.py -- Complex test of canvas, memory canvas, icon,  drawing and etc.
	    X version has bug in ClearRect. See file V.BUGS.

demo4.py -- Using of Timer Callback.

demo5.py -- Example of filling data in two windows. Each window is 
	    a instance of the class HelloWprld with the timer callback 
	    function, that sends messages to the window

demo6.py -- Font selection test.

demo7.py -- Simple using of class vTextEditorUsing.



                 Useful things.
 --------------------------------------------------------

txtview.py  -- Text Viewer class. Allows to view the lists of 
	       strings. Could be run as standalone application.
	       Runs on X & W95.
	       Useful for other applications. VDB debugger uses it.


vdb.py      -- Frontend for the debugger pdb.py. I started to write it
	       as a demo application but very quickly I understood, 
	       that I need it. I did it quick and dirty but I use
	       vdb and I like it.
	       If you want to use vdb, don't forget to define in
	       setup window absolute paths to the files of python exec,
	       pdb.py (It should be in standard Lib). Python file is
	       the file, that you are going to debug.
	       Current version works only under UNIX. It uses things 
	       like fork, bidirectional pipes, XtAddInput in order
	       to connect to X11 select. vdb.py saves windows geometry
	       and settings in the file vdb.rc.
