Class: dragElementHandler

Methods

---

handleDragEnd(host, handler, cursor, event) <static>

Updates the model after dragging selected element(s) has finished.

This method removes any interactive dimensions or snap point indicators from the scene overlay and checks if an element was dragged in to or out of a container element such as a space. If the dragged element was itself a space, it also initiates a check for any spatial overlap on the level. It then updates the user interface as required.

Parameters:

Name	Type	Description
host	PD.SelectionManager	The selection manager.
handler	BIM.UserModeHandler	The user interaction handler.
cursor	PD.Cursor	The cursor that just finished moving.
event	object	The DOM event that triggered the end of the move.

Returns:

Returns true if the move was finalised.
