When handling crossing events, this property is updated before [signalGtk.DropControllerMotion::enter], but after [signalGtk.DropControllerMotion::leave] is emitted.

Parameters:

• contains_pointer (Boolean)

Returns:

• (Boolean) —

  contains-pointer

• (Boolean) —

  contains-pointer

#contains_pointer? ⇒ Boolean

Whether the pointer of a Drag-and-Drop operation is in the controller's widget or a descendant.

When handling crossing events, this property is updated before [signalGtk.DropControllerMotion::enter], but after [signalGtk.DropControllerMotion::leave] is emitted.

Returns:

• (Boolean) —

  contains-pointer

#drop ⇒ Gdk::Drop

The ongoing drop operation over the controller's widget or its descendant.

If no drop operation is going on, this property returns nil.

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 [signalGtk.DropControllerMotion::enter], but after [signalGtk.DropControllerMotion::leave] is emitted.

Returns:

• (Gdk::Drop) —

  drop

#drop=(drop) ⇒ Gdk::Drop

The ongoing drop operation over the controller's widget or its descendant.

If no drop operation is going on, this property returns nil.

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 [signalGtk.DropControllerMotion::enter], but after [signalGtk.DropControllerMotion::leave] is emitted.

Parameters:

• drop (Gdk::Drop)

Returns:

• (Gdk::Drop) —

  drop

• (Gdk::Drop) —

  drop

#is_pointer ⇒ Boolean

Returns if a Drag-and-Drop operation is within the widget self, not one of its children.

Returns:

• (Boolean) —

  true if a dragging pointer is within self but not one of its children

#is_pointer=(is_pointer) ⇒ Boolean

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

See also [propertyGtk.DropControllerMotion:contains-pointer].
