This event gives the application the chance to decide if a drag should be started. dragSetData is called when the data is required from the drag source. dragFinished is called when the drop has successfully completed (mouse up over a valid target) or has been terminated (such as hitting the ESC key). Perform cleanup such as removing data from the source side on a successful move operation. | |
