Self-contained handler of series of events.
This is an abstract base class, low-level implementation for event controllers. Those react to a series of Gdk::Events, and possibly trigger actions as a consequence of those.

Glib::RefPtr< const Gdk::Event > Gtk::EventController::get_current_event | ( | ) | const |
Returns the event that is currently being handled by the controller.
At other times, nullptr
is returned.
Glib::RefPtr< Gdk::Device > Gtk::EventController::get_current_event_device | ( | ) |
Returns the device of the event that is currently being handled by the controller.
At other times, nullptr
is returned.
Glib::RefPtr< const Gdk::Device > Gtk::EventController::get_current_event_device | ( | ) | const |
Returns the event that is currently being handled by the controller.
At other times, nullptr
is returned.
Gdk::ModifierType Gtk::EventController::get_current_event_state | ( | ) | const |
Returns the modifier state of the event that is currently being handled by the controller.
At other times, 0 is returned.
guint32 Gtk::EventController::get_current_event_time | ( | ) | const |
Returns the timestamp of the event that is currently being handled by the controller.
At other times, 0 is returned.
Glib::ustring Gtk::EventController::get_name | ( | ) | const |
Gets the name of controller.
PropagationLimit Gtk::EventController::get_propagation_limit | ( | ) | const |
Gets the propagation limit of the event controller.
PropagationPhase Gtk::EventController::get_propagation_phase | ( | ) | const |
Gets the propagation phase at which controller handles events.

Glib::PropertyProxy< Glib::ustring > Gtk::EventController::property_name | ( | ) |
The name for this controller, typically used for debugging purposes.
Default value: ""
Glib::PropertyProxy_ReadOnly< Glib::ustring > Gtk::EventController::property_name | ( | ) | const |
The name for this controller, typically used for debugging purposes.
Default value: ""
Glib::PropertyProxy< PropagationLimit > Gtk::EventController::property_propagation_limit | ( | ) |
The limit for which events this controller will handle.
Default value: Gtk::PropagationLimit::SAME_NATIVE
Glib::PropertyProxy_ReadOnly< PropagationLimit > Gtk::EventController::property_propagation_limit | ( | ) | const |
The limit for which events this controller will handle.
Default value: Gtk::PropagationLimit::SAME_NATIVE
Glib::PropertyProxy< PropagationPhase > Gtk::EventController::property_propagation_phase | ( | ) |
The propagation phase at which this controller will handle events.
Default value: Gtk::PropagationPhase::BUBBLE
Glib::PropertyProxy_ReadOnly< PropagationPhase > Gtk::EventController::property_propagation_phase | ( | ) | const |
The propagation phase at which this controller will handle events.
Default value: Gtk::PropagationPhase::BUBBLE
Glib::PropertyProxy_ReadOnly< Widget * > Gtk::EventController::property_widget | ( | ) | const |
The widget receiving the Gdk::Events
that the controller will handle.
void Gtk::EventController::reset | ( | ) |
Resets the controller to a clean state.
void Gtk::EventController::set_name | ( | const Glib::ustring & | name | ) |
Sets a name on the controller that can be used for debugging.
name | A name for controller. |
void Gtk::EventController::set_propagation_limit | ( | PropagationLimit | limit | ) |
Sets the event propagation limit on the event controller.
If the limit is set to Gtk::PropagationLimit::SAME_NATIVE, the controller won't handle events that are targeted at widgets on a different surface, such as popovers.
limit | The propagation limit. |
void Gtk::EventController::set_propagation_phase | ( | PropagationPhase | phase | ) |
Sets the propagation phase at which a controller handles events.
If phase is Gtk::PropagationPhase::NONE, no automatic event handling will be performed, but other additional gesture maintenance will.
phase | A propagation phase. |

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