ui/bindings/draggableviewmixin

A mixin that brings the possibility to observe dragging of the view element. The view has to implement the DraggableView interface to use it:

export class MyDraggableView extends DraggableViewMixin( View ) implements DraggableView {
		// ...
}

Creating a class extending it attaches a set of mouse and touch listeners allowing to observe dragging of the view element:

• mousedown and touchstart on the view element - starting the dragging.
• mousemove and touchmove on the document - updating the view coordinates.
• mouseup and touchend on the document - stopping the dragging.

The mixin itself does not provide a visual feedback (that is, the dragged element does not change its position) - it is up to the developer to implement it.
