DESCRIPTION

A LibUI::RadioButtons object represents a multiple choice control of check buttons from which only one can be selected at a time.

Functions

Not a lot here but... well, it's just a simple widget.

new( )

    my $lst = LibUI::RadioButtons->new( );

Creates a new radio buttons instance.

append( )

   $lst->append( 'English' );

Appends a radio button.

onSelected( ... )

    $lst->onSelected(
    sub {
        my ($ctrl, $data) = @_;
        warn $ctrl->selected;
    }, undef);

Registers a callback for when radio button is selected.

Expected parameters include:

$callback - CodeRef that should expect the following:
$lst - backreference to the instance that initiated the callback
$data - user data registered with the sender instance
$data - user data to be passed to the callback

Note: The callback is not triggered when calling setSelected( ... ).

selected( ... )

    if( $lst->selected == 3 ) {
        ...;
    }

Returns the index of the item selected or -1 if there is no selected element.

setSelected( ... )

    $lst->setSelected( 3 );

Sets the item selected. Pass -1 to clear selection.
