pub struct EventControllerMotion { /* private fields */ }
Expand description
EventControllerMotion
is an event controller tracking the pointer
position.
The event controller offers enter
and leave
signals, as well as
is-pointer
and
contains-pointer
properties
which are updated to reflect changes in the pointer position as it
moves over the widget.
§Properties
§contains-pointer
Whether the pointer is in the controllers widget or a descendant.
See also is-pointer
.
When handling crossing events, this property is updated
before enter
, but after
leave
is emitted.
Readable
§is-pointer
Whether the pointer is in the controllers widget itself, as opposed to in a descendent widget.
See also contains-pointer
.
When handling crossing events, this property is updated
before enter
, but after
leave
is emitted.
Readable
EventController
§name
The name for this controller, typically used for debugging purposes.
Readable | Writeable
§propagation-limit
The limit for which events this controller will handle.
Readable | Writeable
§propagation-phase
The propagation phase at which this controller will handle events.
Readable | Writeable
§widget
The widget receiving the GdkEvents
that the controller will handle.
Readable
§Signals
§enter
Signals that the pointer has entered the widget.
§leave
Signals that the pointer has left the widget.
§motion
Emitted when the pointer moves inside the widget.
§Implements
EventControllerExt
, [trait@glib::ObjectExt
]
GLib type: GObject with reference counted clone semantics.
Implementations§
Source§impl EventControllerMotion
impl EventControllerMotion
Sourcepub fn new() -> EventControllerMotion
pub fn new() -> EventControllerMotion
Sourcepub fn builder() -> EventControllerMotionBuilder
pub fn builder() -> EventControllerMotionBuilder
Creates a new builder-pattern struct instance to construct EventControllerMotion
objects.
This method returns an instance of EventControllerMotionBuilder
which can be used to create EventControllerMotion
objects.
