Detailed Description

Event controller for motion events.

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

Since gtkmm 3.94:

noexcept
Gtk::EventControllerMotion::~EventControllerMotion ( )

Gtk::EventControllerMotion::EventControllerMotion ( )

Member Function Documentation

bool Gtk::EventControllerMotion::contains_pointer ( ) const

Returns the value of the GtkEventControllerMotion:contains-pointer property.

Returns
true if a pointer is within self or one of its children.
static Glib::RefPtr<EventControllerMotion> Gtk::EventControllerMotion::create ( )
static
static GType Gtk::EventControllerMotion::get_type ( )
static

Get the GType for this class, for use with the underlying GObject type system.

GtkEventControllerMotion* Gtk::EventControllerMotion::gobj ( )
inline

Provides access to the underlying C GObject.

const GtkEventControllerMotion* Gtk::EventControllerMotion::gobj ( ) const
inline

Provides access to the underlying C GObject.

GtkEventControllerMotion* Gtk::EventControllerMotion::gobj_copy ( )

Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.

bool Gtk::EventControllerMotion::is_pointer ( ) const

Returns the value of the GtkEventControllerMotion:is-pointer property.

Returns
true if a pointer is within self but not one of its children.
EventControllerMotion& Gtk::EventControllerMotion::operator= ( EventControllerMotion&&  src)
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() but after Gtk::EventControllerMotion::signal_leave() is emitted.

Default value: false

Returns
A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.
Glib::PropertyProxy_ReadOnly< bool > Gtk::EventControllerMotion::property_is_pointer ( ) const

Whether the pointer is in the controllers widget itself, as opposed to in a descendent widget.

See also Gtk::EventControllerMotion::property_contains_pointer().

When handling crossing events, this property is updated before Gtk::EventControllerMotion::signal_enter() but after Gtk::EventControllerMotion::signal_leave() is emitted.

Default value: false

Returns
A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.
Glib::SignalProxy<void(double, double)> Gtk::EventControllerMotion::signal_enter ( )
Slot Prototype:
void on_my_enter(double x, double y)

Flags: Run Last

Signals that the pointer has entered the widget.

Parameters
xCoordinates of pointer location.
yCoordinates of pointer location.
Glib::SignalProxy<void()> Gtk::EventControllerMotion::signal_leave ( )
Slot Prototype:
void on_my_leave()

Flags: Run Last

Signals that the pointer has left the widget.

Glib::SignalProxy<void(double, double)> Gtk::EventControllerMotion::signal_motion ( )
Slot Prototype:
void on_my_motion(double x, double y)

Flags: Run First

Emitted when the pointer moves inside the widget.

Parameters
xThe x coordinate.
yThe y coordinate.
