Description

bBrowser:CellDragDrop() is a callback method that is called during a drag & drop process. The method checks whether a method with the same name is defined in the owner of the bBrowser and calls this with an object of class bCellDragEvent as argument.

The entire drag & drop process is divided into several modes that can occur in the server and/or in the client. For each mode the browser calls the method CellDragDrop() with the appropriate mode. The owner of the browser can react by means of its own CellDragDrop() method to these modes.
