Ok I investigated how windows does this, and its algorithm is this:

On mouse-down, if the clicked item can be dragged, do nothing, otherwise raise and \
pass click. If it is possible for the item to be dragged, wait for mouse-up or \
mouse-move to decide what to do.

The trouble with implementing this on linux, is that there is no easy way (afaics) to \
tell whether the item under the mouse can be dragged.

I looked in Qt a while ago, and QWidget's don't seem to make that information \
available - to support d&d you just modify the onMouseMove event (or something). \
