As shown in program 1-11, with the -label
option, we can put a label next to the button subwidgets as the
caption of the TixSelect widget. We can also control the layout of
the button subwidgets using the -orientation option. The -orientation option can have two values: horizontal (the
default value) or vertical, and the buttons are lied up
accordingly. Figure 1-12 shows the output of a
TixSelect widget whose -orientation is set to vertical.
