NAME
Gtk2::Ex::Spinner::EntryWithCancel -- Gtk2::Entry with a cancelled property
SYNOPSIS
use Gtk2::Ex::Spinner::EntryWithCancel;
my $entry = Gtk2::Ex::Spinner::EntryWithCancel->new;
$entry->signal_connect ('editing-done',
sub {
if ($entry->get('editing-cancelled'))
...
});
WIDGET HIERARCHY
Gtk2::Ex::Spinner::EntryWithCancel
is a subclass of Gtk2::Entry
.
Gtk2::Widget
Gtk2::Entry
Gtk2::Ex::Spinner::EntryWithCancel
And implements the interface
Gtk2::CellEditable
DESCRIPTION
Gtk2::Ex::Spinner::EntryWithCancel
is based on a great Gtk2::Ex::DateSpinner::EntryWithCancel, so in most cases documentation is the same. License is (of course) the same too :-).
Caution: This is internals of Gtk2::Ex::Spinner::CellRenderer
. If it ends up with a use beyond that then it'll be split out and renamed.
EntryWithCancel
extends Gtk2::Entry
to have an "editing-cancelled" flag set when editing through the Gtk2::CellEditable
interface. An an Escape key press or cancel
action sets the flag.
Gtk2::Entry
already has such a flag (mis-spelt editing_canceled
) but doesn't make it publicly available. Is that right? At any rate this subclass gets the desired effect.
FUNCTIONS
$entry = Gtk2::Ex::Spinner::EntryWithCancel->new (key=>value,...)
-
Create and return a new EntryWithCancel object. Optional key/value pairs set initial properties as per
Glib::Object->new
. Eg.my $entry = Gtk2::Ex::Spinner::EntryWithCancel->new (xalign => 0.5);
$entry->cancel ()
-
Emit the
cancel
action signal, thus performing that action (see "SIGNALS" below).
PROPERTIES
editing-cancelled
(boolean, default false)-
Cleared by
start_editing
(theGtk2::CellEditable
func) and then set to true or false under an Escape (keypress),cancel
(below), oractivate
(Gtk2::Widget
signal).editing-done
handlers (theGtk2::CellEditable
signal) can then consult the value.
SIGNALS
cancel
(action, no parameters)-
Perform the cancel action, which is to set the
editing-cancelled
property, and if editing is active (from astart_editing
) then emitediting-done
andremove-widget
.The
Escape
key binding runs this signal.
