Declaration

Source position: controls.pp line 444

type TEndDragEvent = procedure(

  Sender: TObject;

  Target: TObject;

  X: Integer;

  Y: Integer

) of object;

Arguments

Sender

  

The dragged control.

Target

  

The drop target (control), or Nil if cancelled.

X

  

The mouse coordinate, in client coordinates if dropped, else in screen coordinates.

Y

  

The mouse coordinate, in client coordinates if dropped, else in screen coordinates.

Description

An OnEndDrag event is sent for a dragged control, when the drag operation is finished. This happens regardless of whether the operation was drag-drop or drag-dock, and whether the operation ended with a drop or was cancelled.

Check for an unassigned value in Target to distinguish between a drop and a cancelled operation (Nil).
