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.

-label¶
Sets the initial label for the checkbox widget to the passed string or value.
-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.
