## The `dragsource' property

Valid for: All visible controls

Read-only, character vector

The `dragsource` property is used in drag-and-drop operations. When a drag-and-drop callback occurs (i.e. one of `onDragStart`, `onDragEnd`, `onDragOver`, `onDragEnter`, `onDragLeave`, `onDragDrop`), the `dragsource` property contains the name of the control which is being dragged.
