- # Tix Demostration Program
- #
- # This sample program is structured in such a way so that it can be
- # executed from the Tix demo program "widget": it must have a
- # procedure called "RunSample". It should also have the "if" statment
- # at the end of this file so that it can be run as a standalone
- # program using tixwish.
-
- # This file demonstrates the use of the tixComboBox widget, which is close
- # to the MS Window Combo Box control.
- #

-
- # Create the comboboxes on the top of the dialog box

-
- # $w.top.a is a drop-down combo box. It is not editable -- who wants
- # to invent new months?
- #
- # [Hint] The -options switch sets the options of the subwidgets.
- # [Hint] We set the label.width subwidget option of both comboboxes to
- # be 10 so that their labels appear to be aligned.

-
- # $w.top.b is a non-drop-down combo box. It is not editable: we provide
- # four choices for the user, but he can enter an alternative year if he
- # wants to.
- #
- # [Hint] Use the padY and anchor options of the label subwidget to
- # aligh the label with the entry subwidget.
- # [Hint] Notice that you should use padY (the NAME of the option) and not
- # pady (the SWITCH of the option).
