NAME

Tickit::Console::Tab - represent a single tab on a Tickit::Console

DESCRIPTION

Objects in this class represent a single switchable tab within a Tickit::Console. They are not constructed directly, but instead are returned by the add_tab method of the underlying Tickit::Console object.

PARAMETERS

The following extra parameters may be passed to the constructor, or via the add_tab method on the Tickit::Console object:

timestamp_format => STRING or String::Tagged

If defined, every line is prefixed with a timestamp built by applying the POSIX::strftime function to this string. If a String::Tagged instance is applied it will preserve all the formatting from it.

datestamp_format => STRING or String::Tagged

If defined, every time a line is added to the buffer, if it starts a new day since the previous message (because the format yields a different string), this message is added as well to the scroller.

METHODS

$name = $tab->name

$tab->set_name( $name )

Returns or sets the tab name text

$tab->append_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.

Also recognises the following options:

time => NUM

Overrides the epoch time() value used to generate a timestamp for this line

timestamp_format => STRING or String::Tagged

Overrides the stored format for generating a timestamp string.

datestamp_format => STRING or String::Tagged

Overrides the stored format for generating a datestamp string.

$tab->prepend_line( $string, %opts )

As append_line, but prepends it at the beginning of the scroller.

$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.
