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
$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 )
METHODS
$tab = $console->add_tab( %args )
Adds a new tab to the console, and returns an object representing it.
Takes the following named arguments:
- name => STRING
-
Name for the tab.
- on_line => CODE
-
Optional. Provides a different callback to invoke when a line of text is entered while this tab is active. Invoked the same way as above.
- make_widget => CODE
-
Optional. Gives a piece of code used to construct the actual Tickit::Widget used as this tab's child in the ribbon. A
Tickit::Widget::Scroller
to hold the tab's content will be passed in to this code, which should construct some sort of widget tree with that inside it, and return it. This can be used to apply a decorative frame, place the scroller in a split box or other layout along with other widgets, or various other effects.$tab_widget = $make_widget->( $scroller )
See "TAB OBJECTS" below for more information about the returned object.
$index = $console->active_tab_index
$tab = $console->active_tab
$console->remove_tab( $tab_or_index )
$console->move_tab( $tab_or_index, $delta )
$console->activate_tab( $tab_or_index )
$console->next_tab
$console->prev_tab
These methods are all passed through to the underlying Tickit::Widget::Tabbed object.
$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.
TAB OBJECTS
$name = $tab->name
$tab->set_name( $name )
Returns or sets the tab name text
$tab->add_line( $string, %opts )
Appends a line of text to the tab. $string
may either be a plain perl string, or an instance of String::Tagged containing formatting tags, as specified by Tickit::Widget::Scroller. Options will be passed to the Tickit::Widget::Scroller::Item::Line used to contain the string.
$tab->bind_key( $key, $code )
Installs a callback to invoke if the given key is pressed while this tab has focus, overwriting any previous callback for the same key. The code block is invoked as
$result = $code->( $tab, $key )
If $code
is missing or undef
, any existing callback is removed.
This callback will be invoked before one defined on the console object itself, if present. If it returns a false value, then the one on the console will be invoked instead.
