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

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.

STANDARD METHODS ^

    focus  onFocus onBlur

See Curses::UI::Widget for an explanation of these.

WIDGET-SPECIFIC METHODS ^

get

Returns the current state of the checkbox (0 == unchecked, 1 == checked).

check

Sets the checkbox to "checked".

uncheck

Sets the checkbox to "unchecked".

toggle

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

onChange

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.

Call the 'loose-focus' routine, causing the widget to lose focus.
