Trait containing all AccelGroup methods.

AccelGroup

Required methods

fn activate<P: IsA<Object>>(
    &self,
    accel_quark: Quark,
    acceleratable: &P,
    accel_key: u32,
    accel_mods: ModifierType
) -> bool

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

accel_quark

the quark for the accelerator name

acceleratable

the gobject::Object, usually a 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

fn disconnect(&self, closure: Option<&Closure>) -> bool

Removes an accelerator previously installed through AccelGroup::connect.

Since 2.20 closure can be None.

closure

the closure to remove from this accelerator group, or None to remove all closures

Returns

true if the closure was found and got disconnected

fn disconnect_key(&self, accel_key: u32, accel_mods: ModifierType) -> bool

Removes an accelerator previously installed through AccelGroup::connect.

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

fn get_is_locked(&self) -> bool

Locks are added and removed using AccelGroupExt::lock and AccelGroupExt::unlock.

Returns

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

fn get_modifier_mask(&self) -> ModifierType

Gets a gdk::ModifierType representing the mask for this self. For example, gdk::ModifierType::ControlMask, gdk::ModifierType::ShiftMask, etc.

Returns

the modifier mask for this accel group.

fn lock(&self)

Locks the given accelerator group.

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

If called more than once, self remains locked until AccelGroupExt::unlock has been called an equivalent number of times.

fn unlock(&self)

Undoes the last call to AccelGroupExt::lock on this self.

fn connect_accel_activate<F: Fn(&Self, &Object, u32, ModifierType) -> bool + 'static>(
    &self,
    f: F
) -> SignalHandlerId

The accel-activate signal is an implementation detail of AccelGroup and not meant to be used by applications.

acceleratable

the object on which the accelerator was activated

keyval

the accelerator keyval

modifier

the modifier combination of the accelerator

Returns

true if the accelerator was activated

fn connect_accel_changed<F: Fn(&Self, u32, ModifierType, &Closure) + 'static>(
    &self,
    f: F
) -> SignalHandlerId

The accel-changed signal is emitted when an entry is added to or removed from the accel group.

Widgets like AccelLabel which display an associated accelerator should connect to this signal, and rebuild their visual representation if the accel_closure is theirs.

keyval

the accelerator keyval

modifier

the modifier combination of the accelerator

accel_closure

the gobject::Closure of the accelerator

fn connect_property_is_locked_notify<F: Fn(&Self) + 'static>(
    &self,
    f: F
) -> SignalHandlerId

fn connect_property_modifier_mask_notify<F: Fn(&Self) + 'static>(
    &self,
    f: F
) -> SignalHandlerId
