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

43 See exampes/demo-Curses::UI::Checkbox in the distribution for a short

55
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.

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
96 "[TAB]", "[ENTER}"
97 Call the 'loose-focus' routine, causing the widget to lose focus.
98
99 "[SPACE]"
100 Call the "toggle" method.

102 0, "n"
103 Call the "uncheck" method.
