s2disp

Draw the scene, but return control when a timeout occurs or when 'TAB' key is pressed.

Prototype

void s2disp(int idelay, int irestorecamera);

Description

Draw the scene, but return control when a timeout occurs or when the user hits the 'TAB' key. In some distributions, this capability is not available - a warning will be issued and s2show will be called implicitly.

• If idelay = 0, the function returns immediately the event buffer is clear.
• If idelay > 0 the function will return after this many seconds or when key is pressed.
• If idelay < 0 there is no timeout, and the function returns when the 'TAB' key is pressed.
• If irestorecamera > 0, the camera will be returned to its "home" position, otherwise it is left in the current position.

#include "s2plot.h"

int main(int argc, char *argv[])
{
   int idelay   = 60;				/* Wait for 60 seconds */
   int irestore = 1;				/* Restore camera to home */

   s2opend("/?",argc, argv);			/* Open the display */
   s2swin(-1.,1., -1.,1., -1.,1.);		/* Set the window coordinates */
   s2box("BCDET",0,0,"BCDET",0,0,"BCDET",0,0);	/* Draw coordinate box */
   s2disp(idelay, irestore);			/* Open the s2plot window */
   
   return 1;
}
