Member Function Documentation

CanHandle()

float xiiLayerOnLayerDragDropHandler::CanHandle ( const xiiDragDropInfo * pInfo ) const

overridevirtual

Used to ask a handler whether it knows how to handle a certain drag & drop situation.

The return value is a priority. By default CanHandle should return 0 or 1. To override an existing handler, values larger than 1 may be returned to take precedence.

Implements xiiDragDropHandler.

OnDrop()

void xiiLayerOnLayerDragDropHandler::OnDrop ( const xiiDragDropInfo * pInfo )

overridevirtual

Final call to finish the drag & drop operation. Handler is destroyed after this.

Implements xiiDragDropHandler.
