NAME
Curses::UI::Menubar - Create and manipulate menubar widgets
CLASS HIERARCHY
Curses::UI::Widget
|
+----Curses::UI::Container

+----Curses::UI::Menubar
SYNOPSIS
use Curses::UI;
my $cui = new Curses::UI;
# define the menu datastructure.
my $menu_data = [....];
my $menu = $cui->add(
'menu', 'Menubar',
-menu => $menu_data
);
$menu->focus();
DESCRIPTION
This class can be used to add a menubar to Curses::UI. This menubar can contain a complete
submenu hierarchy. It looks (remotely :-) like this:
-------------------------------------
menu1 | menu2 | menu3 | ....
-------------------------------------
+-------------+
|menuitem 1 |
|menuitem 2 |+--------------+
|menuitem 3 >>||submenuitem 1 |
|menuitem 4 ||submenuitem 2 |
+-------------+|submenuitem 3 |
|submenuitem 4 |
|submenuitem 5 |
+--------------+
See exampes/demo-Curses::UI::Menubar in the distribution for a short demo.
STANDARD OPTIONS
This class does not use any of the standard options that are provided by
Curses::UI::Widget.
WIDGET-SPECIFIC OPTIONS
There is only one option: -menu. The value for this option is an ARRAYREF. This ARRAYREF
behaves exactly like the one that is described in Curses::UI::MenuListbox. The difference
is that for the top-level menu, you will only use -submenu's. Example data structure:
my $menu1 = [
{ -label => 'option 1', -value => '1-1' },
{ -label => 'option 2', -value => '1-2' },
{ -label => 'option 3', -value => '1-3' },
];
my $menu2 = [
{ -label => 'option 1', -value => \&sel1 },
{ -label => 'option 2', -value => \&sel2 },
{ -label => 'option 3', -value => \&sel3 },
];
my $submenu = [
{ -label => 'suboption 1', -value => '3-3-1' },
{ -label => 'suboption 2', -callback=> \&do_it },
];
my $menu3 = [
{ -label => 'option 1', -value => \&sel2 },
{ -label => 'option 2', -value => \&sel3 },
{ -label => 'submenu 1', -submenu => $submenu },
];
my $menu = [
{ -label => 'menu 1', -submenu => $menu1 },
{ -label => 'menu 2', -submenu => $menu2 }
{ -label => 'menu 3', -submenu => $menu3 }
];
METHODS
o new ( OPTIONS )
o layout ( )
o draw ( BOOLEAN )
o focus ( )
These are standard methods. See Curses::UI::Widget for an explanation of these.
DEFAULT BINDINGS
o <escape>
Call the 'escape' routine. This will have the menubar loose its focus and return the
value 'ESCAPE' to the calling routine.
o <tab>
Call the 'return' routine. This will have the menubar loose its focus and return the
value 'LOOSE_FOCUS' to the calling routine.
o <cursor-down>, <j>, <enter>
Call the 'pulldown' routine. This will open the menulistbox for the current menu and
give that menulistbox the focus. What happens after the menulistbox loses its focus,
depends upon the returnvalue of it:
* the value 'CURSOR_LEFT'
Call the 'cursor-left' routine and after that
call the 'pulldown' routine. So this will open
the menulistbox for the previous menu.
* the value 'CURSOR_RIGHT'
Call the 'cursor-right' routine and after that
call the 'pulldown' routine. So this will open
the menulistbox for the next menu.
* the value 'LOOSE_FOCUS'
The menubar will keep the focus, but no
menulistbox will be open.
* the value 'ESCAPE'
The menubar will loose its focus and return the
value 'ESCAPE' to the calling routine.
* A CODE reference
The code will be excuted, the menubar will loose its
focus and the returnvalue of the CODE will be
returned to the calling routine.
* Any other value
The menubar will loose its focus and the value will
be returned to the calling routine.
o <cursor-left>, <h>
Call the 'cursor-left' routine. This will select the previous menu. If the first menu
is already selected, the last menu will be selected.
o <cursor-right>, <l>
Call the 'cursor-right' routine. This will select the next menu. If the last menu is
already selected, the first menu will be selected.
