Tkinter, tkFileDialog, and checkbuttons

[Frank Chen]

Hi:

The attahced file is an example that confuses me.
When executing test.py and then click [File] menu,
you can see the menu constitutes 'New Window',
'Open File', and an activated checkbutton, 'Show toolbar'.

Now please select 'New Window', which will cause App class
to generate a child root derived from Tk(). The status of the
checkbuttons becomes unselected.

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

It will be grateful if someone can tell me how to cope with this.

attachements, post your text in line. Thank you.

Now please select 'New Window', which will cause App class
to generate a child root derived from Tk(). The status of the
checkbuttons becomes unselected.
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'?, .......
