All checkbuttons use the same variable, try:
        self.checkmark=StringVar()
        self.menu.menu.add_checkbutton(label='Show tool bar', underline=0,

variable=self.checkmark,

> And if you select 'Open File' of child root window, the main root
> Tk() will be popped  up to the layer above child root.

Try:
           tkFileDialog.askopenfilename(
                                     parent=self.master,

BTW there are a lot of questionable constructs in your program. You are
using 'app' as local  variable in new_window which might lead to garbage
collecting the App-instance at an inapropriate situation, the packs() will
not work well when resizing the window, why do you separate initialization
from 'create'?, .......
