Gtk2::BindingSet(3)   User Contributed Perl Documentation  Gtk2::BindingSet(3)

NAME
       Gtk2::BindingSet

DESCRIPTION
       A "Gtk2::BindingSet" is basically a mapping from keyval+modifiers to a
       named action signal to invoke and with argument values for the signal.
       Bindings are normally run by the "Gtk2::Widget" default
       "key-press-event" handler, but can also be activated explicitly.

       Binding sets can be populated from program code with
       "entry_add_signal", or created from an RC file or string (see
       Gtk2::Rc).  If you use the RC note it doesn't parse and create anything
       until there's someone interested in the result, such as
       "Gtk2::Settings" for widgets.  This means binding sets in RC files or
       strings don't exist for "Gtk2::BindingSet->find" to retrieve until at
       least one widget has been created (or similar).

       Currently there's no Perl-level access to the contents of a BindingSet,
       except for "set_name".

METHODS
   GtkBindingSet = Gtk2::BindingSet->new ($set_name)
       ·   $set_name (string)

   boolean = $binding_set->activate ($keyval, $modifiers, $object)
       ·   $keyval (integer)

       ·   $modifiers (Gtk2::Gdk::ModifierType)

       ·   $object (Gtk2::Object)

   $binding_set->add_path ($path_type, $path_pattern, $priority)
       ·   $path_type (Gtk2::PathType)

       ·   $path_pattern (string)

       ·   $priority (integer)

       The following constants are defined for standard priority levels,

	   Gtk2::GTK_PATH_PRIO_LOWEST
	   Gtk2::GTK_PATH_PRIO_GTK
	   Gtk2::GTK_PATH_PRIO_APPLICATION
	   Gtk2::GTK_PATH_PRIO_THEME
	   Gtk2::GTK_PATH_PRIO_RC
	   Gtk2::GTK_PATH_PRIO_HIGHEST

       LOWEST, which is 0, and HIGHEST, which is 15, are the limits of the
       allowed priorities.  The standard values are from the
       "Gtk2::PathPriorityType" enum, but the parameter here is an integer,
       not an enum string, so you can give a value for instance a little above
       or below the pre-defined levels.

   bindingset or undef = Gtk2::BindingSet->by_class ($name)
       ·   $name (string)

   $binding_set->entry_add_signal ($keyval, $modifiers, $signal_name)
   $binding_set->entry_add_signal ($keyval, $modifiers, $signal_name,
       $type,$value, ...)
       ·   $keyval (integer)

       ·   $modifiers (Gtk2::Gdk::ModifierType)

       ·   $signal_name (string)

       ·   $value (scalar)

       ·   $type (string)

       Add an entry to $binding_set.  $keyval and $modifier are setup as a
       binding for $signal_name and with signal parameters given by $value
       arguments.  Each value is preceded by a type (a string), which must be
       one of

	   Glib::Long
	   Glib::Double
	   Glib::String
	   an enum type, ie. subtype of Glib::Enum
	   Glib::Flags, or a flags subtype

       For example,

	   $binding_set->entry_add_signal
	       (Gtk2->keyval_from_name('Return'),
		[ 'control-mask' ],   # modifiers
		'some-signal-name',
		'Glib::Double', 1.5,
		'Glib::String,	'hello');

       A parameter holds one of the three types Long, Double or String.	 When
       invoked they're coerced to the parameter types expected by the target
       object or widget.  Use Glib::Long for any integer argument, including
       chars and unichars by ordinal value.  Use Glib::Double for both single
       and double precision floats.

       Flags and enums are held as Longs in the BindingSet.  You can pass an
       enum type and string and "entry_with_signal" will lookup and store
       accordingly.  For example

	   $binding_set->entry_add_signal
	       (Gtk2->keyval_from_name('Escape), [],
		'set-direction',
		'Gtk2::Orientation', 'vertical');

       Likewise flags from an arrayref,

	   $binding_set->entry_add_signal
	       (Gtk2->keyval_from_name('d'), [],
		'initiate-drag',
		'Gtk2::Gdk::DragAction', ['move,'ask']);

       If you've got a Glib::Flags object, rather than just an arrayref, then
       you can just give Glib::Flags as the type and the value is taken from
       the object.  For example,

	   my $flags = Gtk2::DebugFlag->new (['tree', 'updates']);
	   $binding_set->entry_add_signal
	       (Gtk2->keyval_from_name('x'), ['control-mask'],
		'change-debug',
		'Glib::Flags', $flags);

   $binding_set->entry_remove ($keyval, $modifiers)
       ·   $keyval (integer)

       ·   $modifiers (Gtk2::Gdk::ModifierType)

   $binding_set->entry_skip ($keyval, $modifiers)
       ·   $keyval (integer)

       ·   $modifiers (Gtk2::Gdk::ModifierType)

       Since: gtk+ 2.12

   bindingset or undef = Gtk2::BindingSet->find ($name)
       ·   $name (string)

   string = $binding_set->set_name
       Return the name of $binding_set.
