I while ago on IRC #KDE some guys chatted about that I think tere is a trick 
you can do to get the events, but I am not sure if I remember correctly, and 
if so, I don't know the trick. Did you ask around a little?

I don't understand. Would that mean that piave needs to actively pass all X 
events to kdenlive? Anyway, I like this way much better than Idea 2.

I think I would like a mix of 1 and 3.
1) I don't think piave is the right place to handle mouse/keyboard events. 
Eventually we need to draw points an boxes on the monitor which need to be 
dragged around to position PicInPics and Text and paths for moving effects, 
etc. all this needs a lot of mouse action and surely needs to be handled by 
kdenlive.
2) Do I understand correctly that you want to drag the clip by actually 
clickin into the video window? Why? Why not make it analog to the timeline 
and make the clip in the ruler selectable and then drag the highlighted part 
of the ruler, which represents the clip (after in/out cuts) into the 
timeline? Isn't that a viable solution from a UI point of view?

I'll ask some friends with Xperience ;-)

Cheers,
