Functions

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

new( )

    my $font = LibUI::FontButton->new( );

Creates a new font button.

The default font is determined by the OS defaults.

font( ... )

    my $desc = $font->font;

Returns the selected font.

Note: Make sure to call freeFont() to free all allocated resources within the returned font.

onChanged( ... )

    sub new_font {
        my ($ctrl, $data) = @_;
        my $font = $ctrl->font;
        ...;
    }
    $font->onChanged( \&new_font, undef );

Registers a callback for when the font is changed.

Expected parameters include:

$callback - CodeRef that should expect the following:

$font - 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
