I think I figured it out. draw_row_with_mouse_face() is eventually
called by show_mouse_face(), but it is a noop on my system. Easy to
see:
static void
draw_row_with_mouse_face (struct window *w, int start_x, struct glyph_row *row,
int start_hpos, int end_hpos,
enum draw_glyphs_face draw)
{
#ifdef HAVE_WINDOW_SYSTEM
...
#endif
#if defined (HAVE_GPM) || defined (MSDOS) || defined (WINDOWSNT)
tty_draw_row_with_mouse_face (w, row, start_hpos, end_hpos, draw);
#endif
}
I'm currently using Mac OS. Most of the TTY things work here, and I
would expect drawing some face on a part of the screen to work too. I
can certainly show and hide faces programatically.
I've tried uncommenting that, but it fails during linking.
João
