Rich drag drop user interface

摘要

In an electronic file system, preview information is provided to the user during a drag operation of a selected object onto a target object. The information indicates what type(s) of action is to be taken should the selected object be dropped onto the target object. The action(s) to be taken may depend upon the type of the selected object and/or the type of the target object. For example, where the selected object is an item and the target object is a persisted auto-list, the action may include adding, removing, or modifying one or more properties of the selected object to conform to one or more criteria defined by the persisted auto-list. Also, numerical feedback may be provided to the user where multiple objects are selected. For example, where seven objects are selected, the textual number “7” may appear next to the cursor.

1. One or more computer-readable storage media having computer-executable instructions embodied thereon that, when executed by a computing device, perform a method for dragging and dropping an object, the method comprising:
receiving a user input via a graphical user interface to drag an object proximate to a persisted auto-list, thereby initiating a drag/drop operation; displaying a preview of multiple different types of actions that will take place in response to dropping the object onto the persisted auto-list based on a predefined relationship between the object and the persisted auto-list; receiving additional input from the user during the drag/drop operation that causes a new action in addition to at least one of the multiple different types of actions to take place in response to dropping the objection onto the persisted auto-list; and performing the new action and the at least one of the multiple different types of actions in response to the object being dropped onto the persisted auto-list after said displaying.
