			X Windows Xlib EXAMPLES

I have developed the following series of simple examples that teaches you how
to use the  X Windows Xlib functions:

xpoints  : to draw dots in a window by clicking the left button.
xxpoints : same as above but for more than one display.

xlines   : to draw line segments in a window by clicking the left button,
           then move and click again.

xxlines : same as above but for more than one display and input from one.

xylines: same as xxlines, but allows input from multiple users.

xlines_shift.c : to draw line segments in a window by clicking the left button,
           then move and click again while the shift key is pressed.

xrubber  :  to draw line segments as above but shows the line as a rubber
            band before the second click.

xrubber2.c: to draw line segments as above but shows the line as a rubber
            band before the second click using XOR operator.
xtext: shows how to write and delete text in a window.


xbuttons, xbuttons2: shows how to build push buttons and execute
                     functions associated with the buttons.
