Struct gtk4::DropControllerMotion
source · pub struct DropControllerMotion { /* private fields */ }
Expand description
DropControllerMotion
is an event controller tracking
the pointer during Drag-and-Drop operations.
It is modeled after EventControllerMotion
so if you
have used that, this should feel really familiar.
This controller is not able to accept drops, use DropTarget
for that purpose.
§Properties
§contains-pointer
Whether the pointer of a Drag-and-Drop operation is in the controller’s widget or a descendant.
See also is-pointer
.
When handling crossing events, this property is updated
before enter
, but after
leave
is emitted.
Readable
§drop
The ongoing drop operation over the controller’s widget or its descendant.
If no drop operation is going on, this property returns None
.
The event controller should not modify the @drop, but it might want to query its properties.
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

]
Implementations§
source§impl DropControllerMotion
impl DropControllerMotion
sourcepub fn new() -> DropControllerMotion
pub fn new() -> DropControllerMotion
Creates a new event controller that will handle pointer motion events during drag and drop.
§Returns
a new DropControllerMotion
sourcepub fn builder() -> DropControllerMotionBuilder
pub fn builder() -> DropControllerMotionBuilder
Creates a new builder-pattern struct instance to construct DropControllerMotion
objects.
This method returns an instance of DropControllerMotionBuilder
which can be used to create DropControllerMotion
objects.
