noexcept |
Glib::PropertyProxy_ReadOnly< bool > Gtk::EventControllerMotion::property_contains_pointer_focus | ( | ) | const |
Whether the pointer is in a descendant of the controllers widget.
See Gtk::EventControllerMotion::property_is_pointer_focus().
When handling crossing events, this property is updated before Gtk::EventControllerMotion::signal_enter() or Gtk::EventControllerMotion::signal_leave() are emitted.
Default value: false
Glib::PropertyProxy_ReadOnly< bool > Gtk::EventControllerMotion::property_is_pointer_focus | ( | ) | const |
Whether the pointer is in the controllers widget itself, as opposed to in a descendent widget.
See Gtk::EventControllerMotion::property_contains_pointer_focus().
When handling crossing events, this property is updated before Gtk::EventControllerMotion::signal_enter() or Gtk::EventControllerMotion::signal_leave() are emitted.
Default value: false

void on_my_enter(double x, double y, Gdk::CrossingMode mode, Gdk::NotifyType detail)
Flags: Run First
Signals that the pointer has entered the widget.
x | The x coordinate. |
y | The y coordinate. |
mode | Crossing mode indicating what caused this change. |
detail | Detail indication where the pointer is coming from. |
Glib::SignalProxy<void(Gdk::CrossingMode, Gdk::NotifyType)> Gtk::EventControllerMotion::signal_leave | ( | ) |
void on_my_leave(Gdk::CrossingMode mode, Gdk::NotifyType detail)
