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.

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;
       }
