The configure method
The configure
method can be used to set and retrieve widget configuration
values. For example, to change the width of a button:
$button->configure(-width => 100);
To get the value for a current widget, just supply it without a value:
$button->configure(-width);
The result is an array of scalars; the important values are the last two, which represent the default value and its current value, respectively.
You can also call configure without any options at all,
which will give you a listing of all options and their
values.
