DragSource.DoDragDrop Method

Explanation Start drag & drop.

When this method is executed, it waits for the mouse to move for a certain period of time, and if it does not move, the method ends as it is. Also, if the transfer data is not set in advance, it will end as it is.

When this method is completed, all the data set by the SetString method etc. up to that point will be cleared.

Call format source.DoDragDrop( [ type [, waitTime [, margin ] ] ] )

Return value None

Arguments

integer type

Drag and drop type. Specify the following values. If omitted, it will be $COPYMODE.

Constant	Value	Description
$COPYMODE	256	Copy mode

How to distinguish between copy mode and move mode processing depends on the implementation of the drop destination.
It is now possible to specify $COPYMODE and $MOVEMODE at the same time since Ver.5.0.0
