SYNOPSIS

use Curses::UI;
my $cui = new Curses::UI;
my $win = $cui->add('window_id', 'Window');

my $checkbox = $win->add(
    'mycheckbox', 'Checkbox',
    -label     => 'Say hello to the world',
    -checked   => 1,
);

$checkbox->focus();
my $checked = $checkbox->get();

DESCRIPTION

Curses::UI::Checkbox is a widget that can be used to create a checkbox. A checkbox has a label which says what the checkbox is about and in front of the label there is a box which can have an "X" in it. If the "X" is there, the checkbox is checked (get will return a true value). If the box is empty, the checkbox is not checked (get will return a false value). A checkbox looks like this:

[X] Say hello to the world

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

STANDARD OPTIONS

-parent, -x, -y, -width, -height, -pad, -padleft, -padright, -padtop, -padbottom, -ipad, -ipadleft, -ipadright, -ipadtop, -ipadbottom, -title, -titlefullwidth, -titlereverse, -onfocus, -onblur

For an explanation of these standard options, see Curses::UI::Widget.

WIDGET-SPECIFIC OPTIONS

• -label < TEXT >

  This will set the text label for the checkbox widget to TEXT.

• -checked < BOOLEAN >

  This option determines if at creation time the checkbox should be checked or not. By default this option is set to false, so the checkbox is not checked.

• -onchange < CODEREF >

  This sets the onChange event handler for the checkbox widget. If the checkbox is toggled, the code in CODEREF will be executed. It will get the widget reference as its argument.

METHODS

• new ( OPTIONS )

• layout ( )

• draw ( BOOLEAN )

• intellidraw ( )

• focus ( )

• onFocus ( CODEREF )

• onBlur ( CODEREF )

  These are standard methods. See Curses::UI::Widget for an explanation of these.

• get ( )

  This method will return the current state of the checkbox (0 = not checked, 1 = checked).

• check ( )

  This method can be used to set the checkbox to its checked state.

• uncheck ( )

  This method can be used to set the checkbox to its unchecked state.

• toggle ( )

  This method will set the checkbox in "the other state". This means that the checkbox will get checked if it is not and vice versa.

• onChange ( CODEREF )

  This method can be used to set the -onchange event handler (see above) after initialization of the checkbox.

DEFAULT BINDINGS

• <tab>, <enter>

  Call the 'return' routine. This will have the widget loose its focus.

• <space>

  Call the 'toggle' routine (see the toggle method).

• <0>, <n>

  Call the 'uncheck' routine (see the uncheck method).

• <1>, <y>

  Call the 'check' routine (see the check method).
