DL_DROPPED Overview  Group

The DL_DROPPED notification message signals that the user has completed a drag operation by releasing the left mouse button. A drag list box sends DL_DROPPED to its parent window in the form of a drag list message.

DL_BEGINDRAG 

idCtl = (int) wParam; 

pDragInfo = (LPDRAGLISTINFO) lParam; 

 

Parameters

idCtl

Control identifier of the drag list box.

pDragInfo

Pointer to a DRAGLISTINFO structure that contains the DL_DROPPED notification code, the handle to the drag list box, and the cursor position.

Return Values

No return value.

Remarks

A window procedure typically processes this notification message by inserting or copying the dragged list item before the list item under the cursor. To retrieve the index of the item at the cursor position, use the LBItemFromPoint function. Note that the DL_DROPPED notification message is sent even if the cursor is not on a list item. In that case, LBItemFromPoint returns - 1.
