'''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.
