Question

I thought this would be easy to find, but a google search has been very unhelpful. Is there a simple api to change the mouse cursor in your X window? (I know in windows you can just call “SetCursor”)

Answer 1

#include <X11/cursorfont.h>

/* ... */

Cursor c;

c = XCreateFontCursor(dpy, XC_xterm); 
XDefineCursor(dpy, w, c);

Where dpy is your display, w is your window and XC_xterm is a constant defining the shape of your cursor. Here’s a list of available cursor shape, along with images.
