Detailed Description

Event controller for shortcuts.

Gtk::ShortcutController is an event controller that manages shortcuts.

Most common shortcuts are using this controller implicitly, e.g. by adding a mnemonic underline to a Gtk::Label, or by installing a key binding using gtk_widget_class_add_binding(), or by adding accelerators to global actions using Gtk::Application::set_accels_for_action().

But it is possible to create your own shortcut controller, and add shortcuts to it.

Gtk::ShortcutController implements Gio::ListModel for querying the shortcuts that have been added to it.

ShortcutController as a Buildable

ShortcutControllers can be created in ui files to set up shortcuts in the same place as the widgets.

An example of a UI definition fragment with GtkShortcutController:

<object class='GtkButton'>
  <child>
    <object class='GtkShortcutController'>
      <property name='scope'>managed</property>
      <child>
        <object class='GtkShortcut'>
          <property name='trigger'>& lt;Control& gt;k</property>
          <property name='action'>activate</property>
        </object>
      </child>
    </object>
  </child>
</object>

Member Function Documentation

void Gtk::ShortcutController::add_shortcut

(

const Glib::RefPtr< Shortcut >&

shortcut

)

Adds shortcut to the list of shortcuts handled by self.

If this controller uses an external shortcut list, this function does nothing.

Parameters

shortcut

A Gtk::Shortcut.

static Glib::RefPtr<ShortcutController> Gtk::ShortcutController::create ( )

static

static Glib::RefPtr<ShortcutController> Gtk::ShortcutController::create ( const Glib::RefPtr< Gio::ListModel > &  model )

static

Creates a new shortcut controller that takes its shortcuts from the given list model.

A controller created by this function does not let you add or remove individual shortcuts using the shortcut controller api, but you can change the contents of the model.

Parameters

model

A ListModel containing shortcuts.

Returns

A newly created shortcut controller.

Gdk::ModifierType Gtk::ShortcutController::get_mnemonics_modifiers

(

)

const

Gets the mnemonics modifiers for when this controller activates its shortcuts.

See set_mnemonics_modifiers() for details.

Returns

The controller's mnemonics modifiers.

static GType Gtk::ShortcutController::get_type ( )

static

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

GtkShortcutController* Gtk::ShortcutController::gobj ( )

inline

Provides access to the underlying C GObject.

const GtkShortcutController* Gtk::ShortcutController::gobj ( ) const

inline

Provides access to the underlying C GObject.

GtkShortcutController* Gtk::ShortcutController::gobj_copy

(

)

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

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

noexcept

Glib::PropertyProxy< Gdk::ModifierType > Gtk::ShortcutController::property_mnemonic_modifiers

(

)

The modifiers that need to be pressed to allow mnemonics activation.

Default value: Gdk::ModifierType::ALT_MASK

Returns

A PropertyProxy that allows you to get or set the value of the property, or receive notification when the value of the property changes.

Glib::PropertyProxy_ReadOnly< Gdk::ModifierType > Gtk::ShortcutController::property_mnemonic_modifiers

(

)

const

The modifiers that need to be pressed to allow mnemonics activation.

Default value: Gdk::ModifierType::ALT_MASK

Returns

A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.

Glib::PropertyProxy< ShortcutScope > Gtk::ShortcutController::property_scope

(

)

What scope the shortcuts will be handled in.

Default value: Gtk::ShortcutType::SCOPE_LOCAL

Returns

A PropertyProxy that allows you to get or set the value of the property, or receive notification when the value of the property changes.

Glib::PropertyProxy_ReadOnly< ShortcutScope > Gtk::ShortcutController::property_scope

(

)

const

What scope the shortcuts will be handled in.

Default value: Gtk::ShortcutType::SCOPE_LOCAL

Returns

A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.

void Gtk::ShortcutController::remove_shortcut

(

const Glib::RefPtr< const Shortcut >&

shortcut

)

Removes shortcut from the list of shortcuts handled by self.

If shortcut had not been added to controller or this controller uses an external shortcut list, this function does nothing.

Parameters

shortcut

A Gtk::Shortcut.

void Gtk::ShortcutController::set_mnemonics_modifiers

(

Gdk::ModifierType

modifiers

)

Sets the controller to have the given mnemonics_modifiers.

The mnemonics modifiers determines which modifiers need to be pressed to allow activation of shortcuts with mnemonics triggers.

GTK normally uses the Alt modifier for mnemonics, except in Gtk::PopoverMenus, where mnemonics can be triggered without any modifiers. It should be very rarely necessary to change this, and doing so is likely to interfere with other shortcuts.

This value is only relevant for local shortcut controllers. Global and managed shortcut controllers will have their shortcuts activated from other places which have their own modifiers for activating mnemonics.

Parameters

modifiers

The new mnemonics_modifiers to use.

void Gtk::ShortcutController::set_scope

(

ShortcutScope

scope

)

Sets the controller to have the given scope.

The scope allows shortcuts to be activated outside of the normal event propagation. In particular, it allows installing global keyboard shortcuts that can be activated even when a widget does not have focus.

With Gtk::ShortcutType::SCOPE_LOCAL, shortcuts will only be activated when the widget has focus.

Parameters

scope

The new scope to use.

ShortcutScope Gtk::ShortcutController::set_scope

(

)

const

Gets the scope for when this controller activates its shortcuts.

See set_scope() for details.

Returns

The controller's scope.

Friends And Related Function Documentation

Glib::RefPtr< Gtk::ShortcutController > wrap ( GtkShortcutController *  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.
