I had to add a little bit to make the dialog modal to the parent. So anyway,
here’s to helping! : )
My comments are prefaced with an #A:, and my modifications are surrounded by
the #A tag, #A - #/A, that is.
def tk_wrapgrab(tk, f, kw):
#retrieved from:
http://grokbase.com/t/python/tkinter-discuss/05468hr5qs/making-tkfiledialog-and-tkmessagebox-modal-on-win32
# Wrap a dialog in a grab pair.
# Use to make tkFileDialog and tkMessageBox application-modal.
# Not needed for tkSimpleDialog.
# tk - grab target, this is what will wait for the tkDialog to close
# f - tkFileDialog.askopenfilename, tkMessageBox.showinfo, etc.
# kw - dictionary of key-word arguments to f
kw['parent'] = tk #A: No need to specify parent then. Grab target here is
synonomous to parent.
tk.grab_set() #A: Grab parent, making parent the only active window (of
application) while tkDialog is open.
retval = f(**kw)
#A
tk.wait_variable(retval) #A: Parent wait for the variable, disabling parent
until tkDialog returns. Thus, tkDialogs are application-modal.
# If we did a global grab, the tkDialog would
be globally-modal.
#/A
tk.grab_release()
return retval
