d d � Z d d � Z d d d � Z d d � Z d S) �SearchDialogBaseay Create most of a 3 or 4 row, 3 column search dialog.
The left and wide middle column contain:
1 or 2 labeled text entry lines (make_entry, create_entries);
a row of standard Checkbuttons (make_frame, create_option_buttons),
each of which corresponds to a search engine Variable;
a row of dialog-specific Check/Radiobuttons (create_other_buttons).
The narrow right column contains command buttons
(make_button, create_command_buttons).
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, its execution function, and the
default_command attribute needed in create_widgets. The other
dialogs override attributes and methods, the latter to replace and
add widgets.
