NAME
       FBB::Xpointer - Sets the location of the X-windows pointer


SYNOPSIS
       #include <bobcat/xpointer>

       Linking option: -lbobcat -lX11


DESCRIPTION
       This  class  allows programs running within the X-graphical environment to set and retrieve the X-windows
       pointer location.


NAMESPACE
       FBB
       All constructors, members, operators and manipulators, mentioned in this man-page,  are  defined  in  the
       namespace FBB.


INHERITS FROM
       -


CONSTRUCTORS
       o      Xpointer():
              The  default  constructor.  Connects  to the Display. throws an Exception exception if the display
              cannot be opened. With multiple Xpointer objects, the connection to the  display  is  opened  only
              once.

              This constructor throws an Exception exception if it could not connect to the Display.

       Copy and move constructors (and assignment operators) are available.


MEMBER FUNCTIONS
       o      bool get(int *x, int *y) const:
              Returns  in  its arguments the currnet pointer coordinates relative to the root-window. On success
              true is returned; false is returned if the pointer could not be moved.

       o      bool set(int x, int y) const:
              Sets the pointer to a location whose pixel coordinates are given with respect to the  root-window.
              A  negative x-coordinate is measured from the right screen-margin of the root window (going left),
              a negative y-coordinate is measured from the bottom screen-margin of the root window  (going  up).
              On success true is returned; false is returned if the pointer could not be moved.


EXAMPLE
       #include <iostream>
       #include <string>

       #include <bobcat/xpointer>

       using namespace FBB;

       int main()
       try
       {
           Xpointer xpointer;
           xpointer.verify();

           if (!xpointer.set(100, 200))
               throw string("Set pointer failed");

           int x;
           int y;

           if (!xpointer.get(&x, &y))
               throw string("Get pointer failed");

           cout << "Pointer now at " << x << ", " << y << ’\n’;
       }
       catch (string msg)
       {
           cout << msg << ’\n’;
           return 1;
       }
