Event controller for motion events.
Gtk::EventControllerMotion is an event controller meant for situations where you need to track the position of the pointer.
|
noexcept |

overridenoexcept |
|
protected |
| bool Gtk::EventControllerMotion::contains_pointer | ( | ) | const |
Returns the value of the GtkEventControllerMotion:contains-pointer property.
true if a pointer is within self or one of its children.
|
static |
| Widget* Gtk::EventControllerMotion::get_pointer_origin | ( | ) |
Returns the widget that contained the pointer before.
This function can only be used in handlers for the Gtk::EventControllerMotion::signal_enter() and Gtk::EventControllerMotion::signal_leave() signals.
| const Widget* Gtk::EventControllerMotion::get_pointer_origin | ( | ) | const |
Returns the widget that contained the pointer before.
This function can only be used in handlers for the Gtk::EventControllerMotion::signal_enter() and Gtk::EventControllerMotion::signal_leave() signals.
| Widget* Gtk::EventControllerMotion::get_pointer_target | ( | ) |
Returns the widget that will contain the pointer afterwards.
This function can only be used in handlers for the Gtk::EventControllerMotion::signal_enter() and Gtk::EventControllerMotion::signal_leave() signals.
| const Widget* Gtk::EventControllerMotion::get_pointer_target | ( | ) | const |

noexcept |
| Glib::PropertyProxy_ReadOnly< bool > Gtk::EventControllerMotion::property_contains_pointer | ( | ) | const |
Whether the pointer is in the controllers widget or a descendant.
See also Gtk::EventControllerMotion::property_is_pointer().
When handling crossing events, this property is updated before Gtk::EventControllerMotion::signal_enter() or Gtk::EventControllerMotion::signal_leave() are emitted.
Default value: false
