-= class Gtk::AccelGroup
-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, when using Gtk::ItemFactory, Ruby/GTK2 automatically sets up the accelerators for your menus in the item factory's Gtk::AccelGroup.
-
-((*Note*))
-that accelerators are different from mnemonics. Accelerators are shortcuts for activating a menu item; they appear alongside the menu item they're a shortcut for. 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 Gtk::Label.new. Menu items can have both accelerators and mnemonics, of course.
-
-=== Example 1. Hello World with Ctrl + 'A'
- require 'gtk2'
-
- ag = Gtk::AccelGroup.new
- ag.connect(Gdk::Keyval::GDK_A, Gdk::Window::CONTROL_MASK,
- Gtk::ACCEL_VISIBLE) {
- p "Hello World."
- }
-
- win = Gtk::Window.new.add_accel_group(ag).show_all
- Gtk.main
-
-=== Example 2. Hello World with 'B' (Using accel path)
- require 'gtk2'
-
- AccelMap.add_entry("<TEST Application>/test", Gdk::Keyval::GDK_B, 0)
- ag = Gtk::AccelGroup.new
- ag.connect("<TEST Application>/test") {
- p "Hello World."
- }
-
- win = Gtk::Window.new.add_accel_group(ag).show_all
- Gtk.main

-== Object Hierarchy
-* Object
- * GLib::Instantiatable
- * GLib::Object
- * Gtk::AccelGroup
-
-== Class Methods
---- Gtk::AccelGroup.new
- Creates a new Gtk::AccelGroup.
- * Returns: a new Gtk::AccelGroup
-
---- Gtk::AccelGroup.activate(object, accel_key, accel_mods)
- Finds the first accelerator in any Gtk::AccelGroup attached to object that matches accel_key and accel_mods, and activates that accelerator. If an accelerator was activated and handled this keypress, true is returned.
- * object: the GLib::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 (((<GdkModifierType|Gdk::Window#GdkModifierType>)))
- * Returns: true if the accelerator was handled, false otherwise
-
---- Gtk::AccelGroup.from_accel_closure(closure)
- Finds the Gtk::AccelGroup to which closure is connected; see Gtk::AccelGroup#connect.
- * closure: a GLib::Closure
- * Returns: the Gtk::AccelGroup to which closure is connected, or nil
-
---- Gtk::AccelGroup.from_object(object)
- Gets an array of all accel groups which are attached to object.
- * object: a GLib::Object, usually a Gtk::Window
- * Returns: an Array of all accel groups which are attached to object
-
-== Instance Methods
---- connect(accel_key, accel_mods, accel_flags, closure)
---- connect(accel_key, accel_mods, accel_flags) {...}
- Installs an accelerator in this group. When accel_group is being activated in response to a call to Gtk::AccelGroup.activate, closure or block will be invoked if the accel_key and accel_mods from Gtk::AccelGroup.activate match those of this connection.
- Note that, due to implementation details, a single closure can only be connected to one accelerator group.
- * accel_key: key value of the accelerator(the constants are in Gdk::Keyval)
- * accel_mods: modifier combination of the accelerator(((<GdkModifierType|Gdk::Window#GdkModifierType>)))
- * accel_flags: a flag mask to configure this accelerator(((<GtkAccelFlags|Gtk#GtkAccelFlags>)))
- * closure: GLib::Closure to be executed upon accelerator activation
- * {...}: if closure = nil and a block is given, the block will be invoked if the accel_key and accel_mods from Gtk::AccelGroup.activate match those of this connection.
- * Returns: self
-
---- connect(accel_path, closure)
---- connect(accel_path) {...}
- Installs an accelerator in this group, using an accelerator path to look up the appropriate key and modifiers (see Gtk::AccelMap#add_entry). When accel_group is being activated in response to a call to Gtk::AccelGroup.activate, closure or block will be invoked if the accel_key and accel_mods from Gtk::AccelGroup.activate match the key and modifiers for the path.
- * accel_path : path used for determining key and modifiers.
- * closure: GLib::Closure to be executed upon accelerator activation
- * {...}: if closure = nil and a block is given, the block will be invoked if the accel_key and accel_mods from Gtk::AccelGroup.activate match those of this connection.
- * Returns: self
-
---- disconnect(closure)
- Removes an accelerator previously installed through Gtk::AccelGroup#connect.
- * closure: the GLib::Closure to remove from this accelerator group
- * Returns: true if the closure was found and got disconnected
-
---- disconnect_key(accel_key, accel_mods)
- Removes an accelerator previously installed through Gtk::AccelGroup#connect.
- * accel_key: key value of the accelerator (Gdk::Keyval)
- * accel_mods: modifier combination of the accelerator (((<GdkModifierType|Gdk::Window#GdkModifierType>)))
- * Returns: true if there was an accelerator which could be removed, false otherwise
-
---- query(accel_key, accel_mods)
- Queries an accelerator group for all entries matching accel_key and accel_mods.
- * accel_key: key value of the accelerator (Gdk::Keyval)
- * accel_mods: modifier combination of the accelerator (((<GdkModifierType|Gdk::Window#GdkModifierType>)))
- * Returns: an array of location to return the number of entries(Gtk::AccelGroupEntry) found, or nil.
---- lock
---- 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, AccelGroup remains locked until Gtk::AccelGroup#unlock has been called an equivalent number of times.
- * {...}: If block is given, it is locked untill the whole of the block.
- * Returns: self
-
---- unlock
- Undoes the last call to Gtk::AccelGroup#lock on this accel_group.
- * Returns: self
-
---- find {...}
- Finds the first entry in an accelerator group for which block returns true and returns its Gtk::AccelKey.
- * {...}: a block to filter the entries of accel_group with
- * Returns: the key of the first entry passing find_func. The key is owned by GTK+ and must not be freed.
-
-
-== Signals
---- accel-activate: self, arg1, accel_key, accel_mods
- * self: Gtk::AccelGroup
- * arg1: GLib::Object
- * accel_key: Key code constants of Gdk::Keyval
- * accel_mods: ((<GdkModifierType|Gdk::Window#GdkModifierType>))
-
---- accel-changed: self, accel_key, accel_mods
- * self: Gtk::AccelGroup
- * accel_key: Key code constants of Gdk::Keyval
- * accel_mods: ((<GdkModifierType|Gdk::Window#GdkModifierType>)).
