I have no experience in C programming. Don't know if I did the right
thing: I added a print and return in this function:
--8<---------------cut here---------------start------------->8---
xg_set_icon_from_xpm_data (struct frame *f, const char **data)
{
GdkPixbuf *pixbuf = gdk_pixbuf_new_from_xpm_data (data);
printf("Got into xg_set_icon_from_xpm_data.\n");
return 1;
if (!pixbuf)
return false;
if (!FRAME_GTK_OUTER_WIDGET (f))
return false;
gtk_window_set_icon (GTK_WINDOW (FRAME_GTK_OUTER_WIDGET (f)), pixbuf);
g_object_unref (pixbuf);
return true;
}
--8<---------------cut here---------------end--------------->8---
and built emacs from git after ./configure --with-pgtk
. Emacs -Q didn't print the message nor dit it
break. It doesn't seem to get to this function.
