Detect mouse movement in C

i was trying to write a programme in c language which can detect mouse movement, but the prograame which i have written can only detect the mouse click or scroll...

#include<stdio.h>
#include<string.h>
#include <ncurses.h>


int main() {

    int ch, count=0;
    mmask_t old;
    MEVENT event;
   
    initscr ();
    start_color();
    noecho ();
    cbreak ();
    keypad (stdscr, TRUE);

    init_pair(1, COLOR_GREEN, COLOR_WHITE );
   
    mousemask (ALL_MOUSE_EVENTS | REPORT_MOUSE_POSITION, &old);

    while ((ch = wgetch(stdscr)) != 'q') {
        count++;
        switch(ch) {
            case KEY_MOUSE:
           
                if(getmouse (&event) == OK) {
                    mvprintw (count, 0, "Mouse Event %d\n",count);
                }
               
                attron( COLOR_PAIR(1) | A_BLINK );
                bkgd(COLOR_PAIR(1) | A_BLINK );
                mvprintw (event.y,event.x, "hey.");
                refresh();
