DESCRIPTION
Curses::UI::Checkbox provides a checkbox widget.
A checkbox is a control for a boolean value (an on/off toggle). It consists of a box which
will either be empty (indicating off or false) or contain an "X" (indicating on or true).
Following this is a text label which described the value being controlled.
[X] This checkbox is on/true/checked/selected
[ ] This checkbox is off/false/unchecked/deselected
See exampes/demo-Curses::UI::Checkbox in the distribution for a short demo.

WIDGET-SPECIFIC OPTIONS
-label

-checked
Takes a boolean argument. Determines if the widget's initial state is checked or
unchecked. The default is false (unchecked).
-onchange
Expects a coderef and sets it as a callback for the widget. When the checkbox's state is
changed, the given code will be executed.

toggle
Flip-flops the checkbox to its "other" state. If the checkbox is unchecked then it will
become checked, and vice versa.

This method can be used to set the "-onchange" event handler (see above) after
initialization of the checkbox. It expects a coderef as its argument.
