| # 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. | |
| # | |
| proc RunSample {w} { | |
| # Create the comboboxes on the top of the dialog box | |
| # | |
| frame $w.top -border 1 -relief raised | |
| # $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). | |
