Detailed Description

A Gtk::AccelGroup represents a group of keyboard accelerators, typically attached to a toplevel Gtk::Window (with Gtk::Window::add_accel_group()).

Usually you won't need to create a Gtk::AccelGroup directly; instead, gtkmm automatically sets up the accelerators for your menus. Note that accelerators are different from mnemonics. Accelerators are shortcuts for activating a menu item; they appear alongside the menu item for which they're a shortcut. For example "Ctrl+Q" might appear alongside the "Quit" menu item. Mnemonics are shortcuts for GUI elements such as text entries or buttons; they appear as underlined characters. See the Gtk::Label constructor. Menu items can have both accelerators and mnemonics, of course.

You can use Gtk::Window::get_accel_group() to get an accel group for that window, then use it with other widgets too.

Member Function Documentation

static bool Gtk::AccelGroup::activate	(	Gtk::Object&	object,
		guint	accel_key,
		Gdk::ModifierType	accel_mods
	)			[static]

Finds the first accelerator in any Gtk::AccelGroup attached to object that matches accel_key and accel_mods, and activates that accelerator.

Parameters:

	object	The Object, usually a Gtk::Window, on which to activate the accelerator.
	accel_key	Accelerator keyval from a key event.
	accel_mods	Keyboard state mask from a key event.

Returns:

true if an accelerator was activated and handled this keypress.

bool Gtk::AccelGroup::activate	(	GQuark	accel_quark,
		const Glib::RefPtr< Glib::Object > &	acceleratable,
		guint	accel_key,
		Gdk::ModifierType	accel_mods
	)

Finds the first accelerator in accel_group that matches accel_key and accel_mods, and activates it.

Parameters:

	accel_quark	The quark for the accelerator name.
	acceleratable	The Object, usually a Gtk::Window, on which to activate the accelerator.
	accel_key	Accelerator keyval from a key event.
	accel_mods	Keyboard state mask from a key event.

Returns:

true if an accelerator was activated and handled this keypress.

static Glib::RefPtr<AccelGroup> Gtk::AccelGroup::create

(

)

[static]

Creates a new Gtk::AccelGroup object.

Returns:

A Glib::RefPtr<> to a newly created Gtk::AccelGroup object.

bool Gtk::AccelGroup::disconnect_key	(	guint	accel_key,
		Gdk::ModifierType	accel_mods
	)

Removes an accelerator previously installed through connect().

Parameters:

	accel_key	Key value of the accelerator.
	accel_mods	Modifier combination of the accelerator.

Returns:

true if there was an accelerator which could be removed, false otherwise.

static Gdk::ModifierType Gtk::AccelGroup::get_default_mod_mask

(

)

[static]

See set_default_mod_mask().

bool Gtk::AccelGroup::get_is_locked

(

)

const

Locks are added and removed using lock() and unlock().

Since gtkmm 2.14:

Returns:

true if there are 1 or more locks on the accel_group, false otherwise.

static Glib::ustring Gtk::AccelGroup::get_label	(	guint	accelerator_key,
		Gdk::ModifierType	accelerator_mods
	)			[static]

Converts an accelerator keyval and modifier mask into a string which can be used to represent the accelerator to the user.

Since gtkmm 2.6:

Parameters:

	accelerator_key	Accelerator keyval.
	accelerator_mods	Accelerator modifier mask.

Returns:

A newly-allocated string representing the accelerator.

Gdk::ModifierType Gtk::AccelGroup::get_modifier_mask

(

)

const

Gets a Gdk::ModifierType representing the mask for this accel_group.

For example, Gdk::CONTROL_MASK, Gdk::SHIFT_MASK, etc.

Since gtkmm 2.14:

Returns:

The modifier mask for this accel group.

const GtkAccelGroup* Gtk::AccelGroup::gobj

(

)

const [inline]

Provides access to the underlying C GObject.

Reimplemented from Glib::ObjectBase.

GtkAccelGroup* Gtk::AccelGroup::gobj

(

)

[inline]

Provides access to the underlying C GObject.

Reimplemented from Glib::ObjectBase.

GtkAccelGroup* Gtk::AccelGroup::gobj_copy

(

)

Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.

void Gtk::AccelGroup::lock

(

)

Locks the given accelerator group.

Locking an acelerator group prevents the accelerators contained within it to be changed during runtime. Refer to Gtk::AccelMap::change_entry() about runtime accelerator changes.

If called more than once, accel_group remains locked until unlock() has been called an equivalent number of times.

static Glib::ustring Gtk::AccelGroup::name	(	guint	accelerator_key,
		Gdk::ModifierType	accelerator_mods
	)			[static]

Converts an accelerator keyval and modifier mask into a string parseable by parse().

For example, if you pass in 'q' and Gdk::CONTROL_MASK, it returns "& lt;Control& gt;q".

virtual void Gtk::AccelGroup::on_accel_changed	(	guint	keyval,
		Gdk::ModifierType	modifier,
		GClosure *	accel_closure
	)			[protected, virtual]

static void Gtk::AccelGroup::parse	(	const Glib::ustring &	accelerator,
		guint &	accelerator_key,
		Gdk::ModifierType&	accelerator_mods
	)			[static]

Parse the accelerator string.

Parameters:

	accelerator	See the Gtk::AccelKey constructor for the format.
	accelerator_key	Output argument
	accelerator_mods	Output argument

static void Gtk::AccelGroup::set_default_mod_mask

(

Gdk::ModifierType

default_mod_mask

)

[static]

Sets the modifiers that will be considered significant for keyboard accelerators.

The default mod mask is Gdk::CONTROL_MASK | Gdk::SHIFT_MASK | Gdk::MOD1_MASK, that is, Control, Shift, and Alt. Other modifiers will ignored by default. You must include at least the three default modifiers in any value you pass to this function.

The default mod mask should be changed on application startup, before using any accelerator groups.

Glib::SignalProxy3< bool,const Glib::RefPtr<Glib::Object>&,guint,Gdk::ModifierType > Gtk::AccelGroup::signal_accel_activate

(

)

Prototype:

bool on_my_accel_activate(const Glib::RefPtr<Glib::Object>& acceleratable, guint keyval, Gdk::ModifierType modifier)

Glib::SignalProxy3< void,guint,Gdk::ModifierType,GClosure* > Gtk::AccelGroup::signal_accel_changed

(

)

Prototype:

void on_my_accel_changed(guint keyval, Gdk::ModifierType modifier, GClosure* accel_closure)

void Gtk::AccelGroup::unlock

(

)

Undoes the last call to lock() on this accel_group.

static bool Gtk::AccelGroup::valid	(	guint	keyval,
		Gdk::ModifierType	modifiers
	)			[static]

Determines whether a given keyval and modifier mask constitute a valid keyboard accelerator.

For example, the 'a' keyval plus Gdk::CONTROL_MASK is valid - this is a "Ctrl+a" accelerator. But you can't, for instance, use the GDK_Control_L keyval as an accelerator.
