Details

The _drop method method is called automatically after a drag object has been dropped on the attached viewer and the viewer does not recognize the rep passed to it. The _drop method is passed the data returned from the call to _getDragData. The _drop method is the last method called in the drop sequence.

If you are using a viewer supplied with SAS/AF software, such as the data table or data form, the location of the drop is automatically translated for you by the attached viewer into coordinates that make sense for that viewer. For example, when the attached viewer is a data table, a table editor, or a subclass of the table editor, the location is translated into cell coordinates. If the attached viewer is a data form, a form editor, or a subclass of the form editor, the location of the drop is the pixel offset measuring from the upper left corner of the the form editor.

Note: If you are using a user-defined viewer, you must translate the pixel offset into units that make sense for your viewer. [cautionend]
