Re: Drag and Drop API in GWT 2.4

Hi Stagirus, if you dont need to drag Widgets you shall be
theoretically able to drag / dragOver / drop any widget.

For that, use widget.addDomHandler (as explained here
http://static.googleusercontent.com/external_content/untrusted_dlcp/www.google.com/fr//events/io/2011/static/presofiles/gwt_html5_a_web_develops_dream.pdf)

But if you need to drag the widget itself you need to use dnd or
gwtquery. The latter has support for cells which I didnt manage to get
working with the native dnd.
