SYNOPSIS

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

           my $buttons = $win->add(
               'mybuttons', 'Buttonbox',
               -buttons   => [
                   {
                     -label => '< Button 1 >',
                     -value => 1,
                     -shortcut => 1
                   },{
                     -label => '< Button 2 >',
                     -value => 2,
                     -shortcut => 2
                   }
               ]

           $buttons->focus();
           my $value = $buttons->get();

DESCRIPTION

       Curses::UI::Buttonbox is a widget that can be used to create an array of buttons (or, of
       course, only one button).

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

-buttons < ARRAYREF >

           This option takes a reference to a list of buttons.  The list may contain both
           predefined button types and complete button definitions of your own.

           * Your own button definition

             A button definition is a reference to a hash. This
             hash can have the following key-value pairs:

             obligatory:
             -----------

             -label      This determines what text should be drawn
                         on the button.

             optional:
             ---------

             -value      This determines the returnvalue for the
                         get() method. If the value is not defined,
                         the get() method will return the index
                         of the button.

             -shortcut   The button will act as if it was pressed
                         if the key defined by -shortcut is pressed

             -onpress    If the value for -onpress is a CODE reference,
                         this code will be executes if the button
                         is pressed, before the buttons widget loses
                         focus and returns.

           * Predefined button type

             This module has a predefined list of frequently used button
             types. Using these in B<-buttons> makes things a lot
             easier. The predefined button types are:

             ok          -label    => '< OK >'
                         -shortcut => 'o'
                         -value    => 1
                         -onpress  => undef

             cancel      -label    => '< Cancel >'
                         -shortcut => 'c'
                         -value    => 0
                         -onpress  => undef

             yes         -label    => '< Yes >'
                         -shortcut => 'y'
                         -value    => 1
                         -onpress  => undef

             no          -label    => '< No >'
                         -shortcut => 'n'
                         -value    => 0
                         -onpress  => undef

           Example:

             ....
             -buttons => [
                 { -label => '< My own button >',
                   -value => 'mine!',
                   -shortcut => 'm' },

                 'ok',

                 'cancel',

                 { -label => '< My second button >',
                   -value => 'another one',
                   -shortcut => 's',
                   -onpress => sub { die "Do not press this button!\n" } }
             ]
             ....

       •   -selected < INDEX >

           By default the first button (index = 0) is active. If you want another button to be
           active at creation time, add this option. The INDEX is the index of the button you
           want to make active.

       •   -buttonalignment < VALUE >

           You can specify how the buttons should be aligned in the widget. Available values for
           VALUE are 'left', 'middle' and 'right'.

       •   -vertical < BOOLEAN >

           When set to a true value, it will cause the buttons to be rendered with vertical
           instead of horizontal alignment.

METHODS

new ( OPTIONS )

       •   layout ( )

       •   draw ( BOOLEAN )

       •   focus ( )

       •   onFocus ( CODEREF )

       •   onBlur ( CODEREF )

       •   draw_if_visible ( )

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

       •   get ( )

           This method will return the index of the currently active button. If a value is given
           for that index (using the -value option, see -buttons above), that value will be
           returned.

DEFAULT BINDINGS

       •   <enter>, <space>

           TODO: Fix dox Call the 'loose-focus' routine. By default this routine will have the
           container in which the widget is loose its focus. If you do not like this behaviour,
           then you can have it loose focus itself by calling:

               $buttonswidget->set_routine('loose-focus', 'RETURN');

           For an explanation of set_routine, see Curses::UI::Widget.

       •   <cursor left>, <h>

           Call the 'previous' routine. This will make the previous button the active button. If
           the active button already is the first button, nothing will be done.

       •   <cursor right>, <l

           Call the 'next' routine. This will make the next button the active button. If the next
           button already is the last button, nothing will be done.

       •   <any other key>

           This will call the 'shortcut' routine. This routine will handle the shortcuts that are
           set by the -shortcuts option.
