I'm not sure if this more related to drag&drop or to the clipboard but here is the point. The objective is to be able to catch dragged files or objects from the system on the newt window. This would allow to obtain a better integration of the application in the operating system. Some examples : - image/3d model viewers - archive managers It would allow the user to drag the files over the application to add them, much more convenient then a file chooser. Doing it the otherway (application to OS) would be interesting too, but one thing at the time :).
In our software, we decide to use Newt, but in order to don't change mouse and key events API, we decide to get mouseEvent and keyEvent from Newt, convert them into AWTEvent and dispatch them to component. We have some problems, particularly on DnD : I doesn't work. So we modify to code in order to bypass Newt Mouse and Key Event, and keep AWTEvent. So we have event as usual and it works. We only change it for Linux (X11).
