DESCRIPTION

A LibUI::Combobox object represents a control to select one item from a predefined list of items via a drop down menu.

Functions

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

new( )

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

Creates a new combo box.

append( )

   $lst->append( 'English' );

Appends an item to the combo box.

clear( )

    $lst->clear( );

Deletes all items from the combo box.

delete( ... )

    $lst->delete( 4 );

Deletes an item at $index from the combo box.

insertAt( ... )

    $lst->insertAt( 10, 'Klingon' );

Inserts an item at $index to the combo box.

numItems( )

    my $count = $lst->numItems;

Returns the number of items contained within the combo box.

onSelected( ... )

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

Registers a callback for when a combo box item 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 == 5) {
        ...;
    }

Returns the index of the item selected. -1 is returned on empty selection.

setSelected( ... )

    $lst->setSelected( 50 );
