DRAG_DROP

Enables or disables the triggering of events that start drag and drop operations from the element on which the user has clicked.

The old version of drag and drop used the mouse to move an element from a starting position to an end position within the object's tree structure.

With the new version, data can be transferred to any other object that also supports drag and drop, including objects in a different application.

If the DRAG_DROP property of the element on which the user clicks is set to *TRUE, the object receives a DD_BeginDrag or BeginDragDrop event, depending on the drag and drop version used.

With the old version, the drag and drop operation is divided into With the old version, the drag and drop operation is divided into three steps::

Start the drag and drop procedure by clicking on the chosen element and keeping the left mouse button depressed. The mouse cursor's appearance will change. The object receives the BeginDragDrop event.
Move the chosen element (while still holding down the left mouse button). When the mouse cursor is moved over an element in the tree structure, either:
- the mouse cursor's appearance does not change, informing the user that the selected element can be released in that position,
- the mouse cursor appears as follows: ("no parking" sign). The user will not be able to release the selected element in that position.

end the drag and drop procedure by releasing the left mouse button while the cursor is over a permitted element.

We recommend using the new version.
