xs2qsp
Which is the currently selected panel?
Prototype
int xs2qsp(void);
Description
In static mode, which panel is currently the chosen panel (using xs2cp)? In dynamic mode, what is the panel number of the callback that is currently being processed?
See Also
| xs2cp | Select a panel for subsequent geometry calls. |
| xs2mp | Modify location of existing panel. |
| xs2qpa | Is specified panel active? |
| xs2qcpa | Is currently selected panel active? |
Code Example
include <stdio.h>
#include <stdlib.h>
#include "s2plot.h"
/* Global variable */
int pid = 0; /* Which panel should be drawn? */
int panel0; /* ID of the master panel */
void cb(double *t, int *kc)
{
int myid = xs2qsp(); /* Query the panel id currently being drawn */
if (myid == panel0) { /* Is this the main panel? */
static int count = 8; /* Counter */
if (count < 0) { /* Is it time to choose a new panel */
pid = random()%3; /* Choose a random new panel */
count = 8; /* Reset the counter */
}
count--; /* Decrease counter */
}
if (myid == pid) { /* If this panel is the selected panel... */
s2box("BCDET",0,0,"BCDET",0,0,"BCDET",0,0); /* Draw coordinate box */
char string[32];
sprintf(string,"I am panel %d",myid); /* Prepare a string */
s2textxy(-1,0,0,string); /* Write the string */
}
}
int main(int argc, char *argv[])
{
int panel1; /* ID of newly created panel */
int panel2; /* ID of newly created panel */
s2opend("/s2mono", argc, argv); /* Open in mono mode */
s2swin(-1.,1., -1.,1., -1.,1.); /* Set the window coordinates */
panel0 = xs2qsp(); /* Get the ID of the master panel */
xs2mp(panel0, 0.0, 0.5, 1.0, 1.0); /* Move default panel to top left */
cs2scb(&cb); /* Install a dynamic callback */
panel1 = xs2ap(0.0, 0.0, 0.5, 0.5); /* Create panel in bottom left */
xs2cp(panel1); /* Choose this panel */
s2swin(-1.,1., -1.,1., -1.,1.); /* Set the window coordinates */
cs2scb(&cb); /* Install a dynamic callback */
panel2 = xs2ap(0.5, 0.0, 1.0, 0.5); /* Create panel in bottom right */
xs2cp(panel2); /* Choose this panel */
s2swin(-1.,1., -1.,1., -1.,1.); /* Set the window coordinates */
cs2scb(&cb); /* Install a dynamic callback */
xs2cp(panel0); /* Go back to main panel */
s2sch(2); /* Set the character height */
s2show(1); /* Open the s2plot window */
return 1;
}
