The code below should poll the mouse and return the coordinates of its
location. (get_button should return the coordinates of the cursor even
when no mouse button was pressed). LEDA-R 3.2.3 compiled with g++ 2.6.3
under solaris 2.3 on a sparc10 gives instead (0,0) for the coordinates:

button: 1 coords: 0 0
button: 2 coords: 0 0
button: 3 coords: 0 0

#include <iostream.h>
#include <LEDA/window.h>
 
main() {
  window W;
  int button;
  double x, y;
  
  while(1)
    if( button = W.get_button( x,y ) )
      cout << "button: " << button << " coords: " << x << " " << y <<  "\n";
}

If you have either encountered this problem and solved it or not
encountered it and are using a different configuration, I would be
glad to hear any suggestions you may have.

Note that read_mouse, the wait-for-a-mouse-button-press version, works fine.

Thanks in advance,
