One of the features of query.Query boxes is that error messages are displayed in the box (in red) rather than in a separate tkinter.messagebox error box (showerror).  This issue is about copying the idea and implementation to config_key.GetKeysDialog.

To make testing of patched methods easier, #6739 is adding a trivial showerror method (= tkinter.messagebox.showerror).  This issue will replace it with Query.showerror

    def showerror(self, message, widget=None):
        (widget or self.entry_error)['text'] = 'ERROR: ' + message

and add something like

        self.entry_error = Label(frame, text=' ', foreground='red',

just above the exit buttons.

This issue should probably add subtests for the ValidationTests.  Message test and line break when needed will be adjusted by visual checks.
