= class Gtk::AccelLabel
The Gtk::AccelLabel widget is a subclass of Gtk::Label that also displays an accelerator key on the right of the label text, e.g. 'Ctl+S'. It is commonly used in menus to show the keyboard short-cuts for commands.
The accelerator key to display is not set explicitly. Instead, the Gtk::AccelLabel displays the accelerators which have been added to a particular widget. This widget is set by calling Gtk::AccelLabel#accel_widget=.
For example, a Gtk::MenuItem widget may have an accelerator added to emit the "activate" signal when the 'Ctl+S' key combination is pressed. A Gtk::AccelLabel is created and added to the Gtk::MenuItem, and Gtk::AccelLabel#accel_widget= is called with the Gtk::MenuItem as the second argument. The Gtk::AccelLabel will now display 'Ctl+S' after its label.
Note that creating a Gtk::MenuItem with Gtk::MenuItem.new (or one of the similar functions for Gtk::CheckMenuItem and Gtk::RadioMenuItem) automatically adds a Gtk::AccelLabel to the Gtk::MenuItem and calls Gtk::AccelLabel#accel_widget= to set it up for you.
A Gtk::AccelLabel will only display accelerators which have Gtk::ACCEL_VISIBLE set (see GtkAccelFlags). A Gtk::AccelLabel can display multiple accelerators and even signal names, though it is almost always used to display just one accelerator key.
== super class
* Gtk::Label
== class methods
--- Gtk::AccelLabel.new(string)
Creates a new Gtk::AccelLabel.
* string: the label string. Must be non-nil
* Returns: a new Gtk::AccelLabel
== public instance methods
--- accel_closure
Returns the accel_closure.
* Returns: the accel_closure(GLib::Closure, or nil.
--- accel_closure=(accel_closure)
Sets the closure to be monitored by this accelerator label. The closure must be connected to an accelerator group; see Gtk::AccelGroup#connect
* accel_closure: the closure(GLib::Closure) to monitor for accelerator changes.
* Returns: the accel_closure
--- set_accel_closure(accel_closure)
Same as accel_closure=.
* accel_closure: the closure(GLib::Closure) to monitor for accelerator changes.
* Returns: self
--- accel_widget
Fetches the widget monitored by this accelerator label.
* Returns : the object monitored by the accelerator label, or nil.
--- accel_widget=(accel_widget)
Sets the widget to be monitored by this accelerator label.
* accel_widget: the widget to be monitored.
* Returns: accel_widget
--- set_accel_widget(accel_widget)
Same as accel_widget=.
* accel_widget: the widget to be monitored.
* Returns: self
--- accel_width
Returns the width needed to display the accelerator key(s). This is used by menus to align all of the Gtk::MenuItem widgets, and shouldn't be needed by applications.
* Returns: the width needed to display the accelerator key(s).
--- refetch
Recreates the string representing the accelerator keys. This should not be needed since the string is automatically updated whenever accelerators are added or removed from the associated widget.
* accel_label : a Gtk::AccelLabel.
* Returns : always returns false.
