DESCRIPTION

33       Curses::UI::Checkbox provides a checkbox widget.
34
35       A checkbox is a control for a boolean value (an on/off toggle). It
36       consists of a box which will either be empty (indicating off or false)
37       or contain an "X" (indicating on or true). Following this is a text
38       label which described the value being controlled.
39
40           [X] This checkbox is on/true/checked/selected
41           [ ] This checkbox is off/false/unchecked/deselected
42
43       See exampes/demo-Curses::UI::Checkbox in the distribution for a short
44       demo.

WIDGET-SPECIFIC OPTIONS

57   -label
58       Sets the initial label for the checkbox widget to the passed string or
59       value.
60
61   -checked
62       Takes a boolean argument. Determines if the widget's initial state is
63       checked or unchecked.  The default is false (unchecked).
64
65   -onchange
66       Expects a coderef and sets it as a callback for the widget. When the
67       checkbox's state is changed, the given code will be executed.
68

STANDARD METHODS

70           layout draw    intellidraw
71           focus  onFocus onBlur
72
73       See Curses::UI::Widget for an explanation of these.
74

WIDGET-SPECIFIC METHODS

76   get
77       Returns the current state of the checkbox (0 == unchecked, 1 ==
78       checked).
79
80   check
81       Sets the checkbox to "checked".
82
83   uncheck
84       Sets the checkbox to "unchecked".
85
86   toggle
87       Flip-flops the checkbox to its "other" state. If the checkbox is
88       unchecked then it will become checked, and vice versa.
89
90   onChange
91       This method can be used to set the "-onchange" event handler (see
92       above) after initialization of the checkbox. It expects a coderef as
93       its argument.
94

DEFAULT BINDINGS

96       "[TAB]", "[ENTER}"
97           Call the 'loose-focus' routine, causing the widget to lose focus.
98
99       "[SPACE]"
100           Call the "toggle" method.
101
102       0, "n"
103           Call the "uncheck" method.
104
105       1, "y"
106           Call the "check" method.
