I kinda new to the Netbeans Platform RCP and I'm currently working on a project using the platform. I'm having a problem implementing drag and drop a node from and Explorer View to a TopComponent. I'll googled as much as possible however I've not been able to find something specific to my need any help will be grateful. I'm willing to share the source code if i have to.

sorry could you limit the scope of your problem or be more specific

I am working on a GIS project, see screen shot below, If you look to the right of the picture you'll see some symbols. i want to be able to drag those symbols and drop them on the map to the center.

The explorer view to the Right Contains some DataNodes and each DataNode contains a DataObject. Now, I understand that in the Netbeans platform to be able to drag an object from the explorer view to another component the object as to Implement Transferable interface. But what i'm not sure of is, is the the DataNodes that will implement the Transferable or the DataObject ? So far, i made my DataObject implement Transferable but each time i debug. The DataFlavor of Drag and Drop Listener for the TopComponent that I am dropping the symbol on keeps returning a null as the transfer object.

Is that specific enough?

The best way to master a framework or platform is to get hold of the documentations. It will be rare to find users of some frameworks in Java as there few developers who actually use Java Technologies for serious development in Nigeria and on this forum. For instance, I taught myself SWT after I needed my application to use native look and feel, the documentation and examples on forums such as vogella.com, stackoverflow.com and the rest were of great help. I have not used Netbeans RCP Platform, but I can deduced by mere reading the challenge that your DataNode should be the one implementing Transferable. Dataobjects as the name implies should be data models which represents the data that your DataNodes should have. I didn't google this, just trying to infer from what you explained.

@kudaisi and co,i must commend you and some guru we have here for always having time to provide useful solutions to peoples problems as they come up on this forum..you are one of the reasons the forum has occupy a regular space in my schedule.

Pls,I want to invite you to act as a consultant for my startup. It comes with reasonable perks anyway but i need you honestly as a critic to my project which is still under construction.
pls i will be waiting for your feedback...thanks

Bro trust me I've gone through the documentation back to back. Anyway thanks, I figured it out after hours of going through documentation all over again, the problem was actually a simple xml error in my Layer.xml. I got the implementation right all along. The transferable can be either the DataObject or the DataNode. But i chosed to go with the DataNode anyway. Gratitudes.
