Detailed Description

Tracking if shortcuts should be activated.

Gtk::ShortcutAction is the object used to describe what a Gtk::Shortcut should do when triggered. To activate a ShortcutAction manually, activate() can be called.

ShortcutActions contain methods that allow easy presentation to end users as well as being printed for debugging.

All ShortcutActions are immutable, you can only specify their properties during construction. If you want to change an action, you have to replace it with a new one. If you need to pass arguments to an action, these are specified by the higher-level Gtk::Shortcut object.

GTK provides various actions:

• Gtk::MnemonicAction: a shortcut action that calls Gtk::Widget::mnemonic_activate()
• Gtk::CallbackAction: a shortcut action that invokes a given callback
• Gtk::SignalAction: a shortcut action that emits a given signal
• Gtk::ActivateAction: a shortcut action that calls Gtk::Widget::activate()
• Gtk::NamedAction: a shortcut action that calls Gtk::Widget::activate_action()
• Gtk::NothingAction: a shortcut action that does nothing

Member Function Documentation

activate()

bool Gtk::ShortcutAction::activate	(	Widget &	widget,
		Flags	flags = static_cast< Flags >(0),
		const Glib::VariantBase &	args = {}
	)

Activates the action on the widget with the given args.

Note that some actions ignore the passed in flags, widget or args.

Activation of an action can fail for various reasons. If the action is not supported by the widget, if the args don't match the action or if the activation otherwise had no effect, false will be returned.

Parameters

flags	Flags to activate with.
widget	Target of the activation.
args	Arguments to pass.

Returns

true if this action was activated successfully.

get_type()

static GType Gtk::ShortcutAction::get_type ( )

static

Get the GType for this class, for use with the underlying GObject type system.

gobj() [1/2]

GtkShortcutAction * Gtk::ShortcutAction::gobj ( )

inline

Provides access to the underlying C GObject.

gobj() [2/2]

const GtkShortcutAction * Gtk::ShortcutAction::gobj ( ) const

inline

Provides access to the underlying C GObject.

gobj_copy()

GtkShortcutAction * Gtk::ShortcutAction::gobj_copy

(

)

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

operator=()

ShortcutAction & Gtk::ShortcutAction::operator= ( ShortcutAction &&  src )

noexcept

parse_string()

static Glib::RefPtr< ShortcutAction > Gtk::ShortcutAction::parse_string ( const Glib::ustring &  string )

static

Tries to parse the given string into an action.

On success, the parsed action is returned. When parsing failed, nullptr is returned.

The accepted strings are:

• nothing, for Gtk::NothingAction
• activate, for Gtk::ActivateAction
• mnemonic-activate, for Gtk::MnemonicAction
• action(NAME), for a Gtk::NamedAction for the action named NAME
• signal(NAME), for a Gtk::SignalAction for the signal NAME

Parameters

string

The string to parse.

Returns

A new Gtk::ShortcutAction.

to_string()

Glib::ustring Gtk::ShortcutAction::to_string

(

)

const

Prints the given action into a human-readable string.

This is meant for debugging and logging. The form of the representation may change at any time and is not guaranteed to stay identical.

Returns

A new string.

wrap()

Glib::RefPtr< Gtk::ShortcutAction > wrap ( GtkShortcutAction *  object, bool  take_copy = false  )

related

A Glib::wrap() method for this object.

Parameters

object	The C instance.
take_copy	False if the result should take ownership of the C instance. True if it should take a new copy or ref.

Returns

A C++ instance that wraps this C instance.
