Accessing the Value of a TixSelect Widget
The
value
of a TixSelect widget is a list of the names of the
button subwidgets that are currently selected. For example, in
program 1-11, if the user has selected the apple
button, then the value of the TixSelect widget will be
apple
. If the user has selected both the apple and the orange
buttons, then the value will be the list
"apple orange"
.
The TixSelect widget supports same set of options as the TixControl widget
for you to access its value: the
-value
option stores the current
value, which can be queried and modified using the cget and configure
methods. You can also use the
-variable
option to specify a global
variable to store the value of the TixSelect widget. The
-command
option specifies a TCL command to be called whenever the user changes the
selection inside a TixSelect widget. This command is called with one
argument: the new value of the TixSelect widget. There is also the
-disablecallback
option which you can use to control whether the command
specified by the
-command
option should be called when the value of
the TixSelect changes.
