Expand description

Trait containing all AccelGroup methods.

Implementors

AccelGroup

Required methods

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 glib::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

Removes an accelerator previously installed through [AccelGroupExtManual::connect()][crate::prelude::AccelGroupExtManual::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

Removes an accelerator previously installed through [AccelGroupExtManual::connect()][crate::prelude::AccelGroupExtManual::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

Locks are added and removed using lock() and unlock().

Returns

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

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

Returns

the modifier mask for this accel group.

Locks the given accelerator group.

Locking an acelerator group prevents the accelerators contained within it to be changed during runtime. Refer to gtk_accel_map_change_entry() about runtime accelerator changes.

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

Undoes the last call to lock() on this self.

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

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 glib::Closure of the accelerator
