IDragProvider interface

Enables a Microsoft UI Automation element to describe itself as an element that can be dragged as part of a drag-and-drop operation.

When to implement

A UI Automation element implements this interface if it can be dragged in a drag-and-drop operation. If an element implements this interface, the interface should be available even when no drag operation is in progress, in which case the interface indicates that the user could drag this item.

Members

The IDragProvider interface inherits from the IUnknown interface. IDragProvider also has these types of members:

• Methods
• Properties

Methods

Properties

The IDragProvider interface has these properties.

Remarks

A provider can implement IDragProvider only on the element being dragged, or it can use an intermediary drag object that implements IDragProvider, in addition to the IDragProvider implementation on the individual element. The intermediary is responsible for firing all events, which enables the provider to support dragging multiple elements at once, and to describe the multi-element drag operation with a single set of drag properties and events.
