Drag a clip in to a Premier Pro panel

Team

I am investigating writing HTML5 panels for Adobe Premiere Pro 2015.

I am educating myself and working my way through the samples using Eclipse and the Adobe Extension Builder 3 plugin.

I am looking for an example of how you drag a clip from Premiere Pro in to a panel and have it register the information regarding the clip.

I have seen examples of dragging from a panel in to the main Premiere Pro interface but not the other way round.

Is it possible in that direction?

Does anyone have some sample code?

Thanks
