This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
I am trying to incorporate a drag-and-drop feature with our product. I have created a new custom view which has a tree structure and am interested in dropping the content from this tree to an already existing tree structure within the application itself.
I have used the same custom transfer type which the product is expecting. However, while debugging I found out that neither the DragSourceEvent's data or datatype are getting set. Both are null values. Moreover my dragSetData is not getting called as well.
