Code Example

#include <stdio.h>

void cb(double *t, int *kc)
{
   int x, y;                                    /* Pixel width and height */
   ss2qsd(&x, &y);                              /* Query screen dimensions */
   char string[32];
   sprintf(string,"dimensions = (%d,%d)",x,y);  /* Write to string */
   s2textxy(0,0,0,string);                      /* Display text */
}

int main(int argc, char *argv[])
{
   fprintf(stderr,"Resize window to see change in panel size");

   s2opend("/s2mono", argc, argv);              /* Open in mono mode */
   s2swin(-1.,1., -1.,1., -1.,1.);              /* Set the window coordinates */
   s2box("BCDET",0,0,"BCDET",0,0,"BCDET",0,0);  /* Draw coordinate box */

   cs2scb(cb);                                  /* Install dynamic callback */
   s2show(1);                                   /* Open the s2plot window */

   return 1;
}
