Drag and drop for a multi-window operating system

A method comprising:

• managing, by a drag and drop manager provided by a processor of a device, a drag session corresponding to a drag event, the drag event including an initial input selecting an item in a window of a first application, a drag gesture moving the item to a particular region, and a release at an end of the drag gesture for dropping the item in the particular region;
• and
• sending, by a user interface (UI) manager provided by the processor, a request to commandeer the drag session to the drag and drop manager, wherein the request to commandeer the drag session disables hit testing for other applications;
• receiving, by the user interface manager, an indication that the release has occurred in the particular region;
• and performing, by the user interface manager, a drop operation, wherein the drop operation includes at least one of opening a window of a second application for the item or opening another window of the first application for the item.

A non-transitory computer-readable medium comprising instructions, which when executed by a computing device, cause the computing device to perform operations comprising:

• receiving an indication, by a drag and drop manager, of a drag gesture selecting an item in a first application;
• sending, by the drag and drop manager, a request for receiving new events associated with a new drag session to an event manager;
• generating, by the drag and drop manager, a new drag session and a drag session identifier associated with the new drag session;
• sending, by the drag and drop manager, a request for a current routing policy to a user interface (UI) manager;
• receiving, from the UI manager, the current routing policy;
• the drab and drop manager setting, based at least in part on the current routing policy, a new routing policy;
• sending, by the drag and drop manager, the new routing policy to the event manager, wherein the event manager updates a routing policy for the new drag session based on the new routing policy.
