以su - root方式登陸的超級用戶，運行glade：

GladeUI-Message: 1 missing displayable value for GtkCellRendererAccel::accel-mode
GladeUI-Message: Glade needs artwork; a default icon will be used for the following classes:
GtkApplicationWindow needs an icon named 'widget-gtk-applicationwindow'
其次在glade完成：
GtkWindow
GtkFixed
GtkLabel
GtkButton
運行 (PS: 19.1.c為源代碼,不會錯的)
