问题
I'm trying to simulate keyboard and mouse events, i've successfully made fake keyboard keydown, keyup. Fake mouse button down, up and fake mouse move, but i don't found how to do fake mouse wheel move, can someone explain to me a simple way to do this in c++?
Mouse Move and Mouse button press:
Display *dpy = XOpenDisplay(NULL);
XTestFakeMotionEvent(dpy, -1, 50, 50, 0);
XTestFakeButtonEvent(dpy, Button1, true, 0);
XTestFakeButtonEvent(dpy, Button1, false, 0);
XFlush(dpy);
XCloseDisplay(dpy);
Keyboard key press:
Display *dpy = XOpenDisplay(NULL);
unsigned int keycode = XKeysymToKeycode(dpy, XK_Super_L);
XTestFakeKeyEvent(dpy, keycode, true, 0);
XTestFakeKeyEvent(dpy, keycode, false, 0);
XFlush(dpy);
XCloseDisplay(dpy);

Isn't a mousewheel step on Linux just another button press? I can't test this for you now, but I recall on my system that rolling the mousewheel simply generated button events. You can test this on your system by running the program xev which displays X input events.
