Hi,I have modified the nanowm.c,when I execute some examples,it always reports
segment error,the error came from the functions of container_buttonup or container_mousemoved,the code as followd:
GrSetGCMode(gc, GR_MODE_XOR|GR_MODE_EXCLUDECHILDREN);
GrGetWindowInfo(window->wid, &info);
GrRect(GR_ROOT_WINDOW_ID,gc,info.x, info.y, pos->width, pos->height);
when execute GrRect,the error occurs.
Thanks a lot!
