Specific drag and drop window monitoring

[ldarrambide]

Hi Gaintaras, Hi all

i'd like to kiss goodbye an old firefox extension and mimic it via QM.

Basically, I need a way to monitor drag'n'drop only in firefox, detecting when mouse down, and
acting on mouse up, depending on the coordinates from start point.

I think I can manage most of the second part (calculate movement direction, what kind of object is dragged etc)
but I need a framework/direction for the first step.

Any help?

TY
