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
