| 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. |
