NAME

Tickit::Console - build full-screen console-style applications

SYNOPSIS

my $console = Tickit::Console->new;

Tickit->new( root => $console )->run;

DESCRIPTION

A Tickit::Console instance is a subclass of Tickit::Widget::VBox intended to help building a full-screen console-style application which presents the user with one or more scrollable text areas, selectable as tabs on a ribbon, with a text entry area at the bottom of the screen for entering commands or other data. As a Tickit::Widget subclass it can be added anywhere within a widget tree, though normally it would be used as the root widget for a Tickit instance.

CONSTRUCTOR

new

$console = Tickit::Console->new( %args );

Returns a new instance of a Tickit::Console. Takes the following named arguments:

on_line => CODE

Callback to invoke when a line of text is entered in the entry widget.

$on_line->( $active_tab, $text );

tab_class => STRING

Optional. If set, gives a class name (which should be a subclass of Tickit::Console::Tab) to construct newly-added tabs with. This setting allows an application to provide new methods in tabs to change behaviours.

timestamp_format, datestamp_format

Optional. If supplied, these will be stored as default values to pass to the tab constructor in the add_tab method.

METHODS

add_tab

$tab = $console->add_tab( %args );

Adds a new tab to the console, and returns a Tickit::Console::Tab object representing it.

Takes the following named arguments:

name => STRING

Name for the tab.

on_line => CODE

Optional. Provides a different callback to invoke when a line of text is entered while this tab is active. Invoked the same way as above.

make_widget => CODE

Optional. Gives a piece of code used to construct the actual Tickit::Widget used as this tab's child in the ribbon. A Tickit::Widget::Scroller to hold the tab's content will be passed in to this code, which should construct some sort of widget tree with that inside it, and return it. This can be used to apply a decorative frame, place the scroller in a split box or other layout along with other widgets, or various other effects.

$tab_widget = $make_widget->( $scroller );

Any other named arguments are passed to the tab's constructor.

active_tab_index

$index = $console->active_tab_index;

active_tab

$tab = $console->active_tab;

remove_tab

$console->remove_tab( $tab_or_index );

move_tab

$console->move_tab( $tab_or_index, $delta );

activate_tab

$console->activate_tab( $tab_or_index );

next_tab

$console->next_tab;

prev_tab

$console->prev_tab;

These methods are all passed through to the underlying Tickit::Widget::Tabbed object.

bind_key

$console->bind_key( $key, $code );

Installs a callback to invoke if the given key is pressed, overwriting any previous callback for the same key. The code block is invoked as

$code->( $console, $key );

If $code is missing or undef, any existing callback is removed.
