'''Define SearchDialogBase used by Search, Replace, and Grep dialogs.'''
from tkinter import *

class SearchDialogBase:
    '''Create most of a modal search dialog (make_frame, create_widgets).

    The wide left column contains:
    1 or 2 text entry lines (create_entries, make_entry);
    a row of standard radiobuttons (create_option_buttons);
    a row of dialog specific radiobuttons (create_other_buttons).

    The narrow right column contains command buttons
    (create_command_buttons, make_button).
    These are bound to functions that execute the command.

    Except for command buttons, this base class is not limited to
    items common to all three subclasses.  Rather, it is the Find dialog
    minus the "Find Next" command and its execution function.
    The other dialogs override methods to replace and add widgets.
