create draggable on mousedown

[ecentinela]

Before 1.6 this was posible with the code:

$('img').bind('mousedown', function(e) {
$(this).draggable().trigger('mousedown.draggable', e);
})

But with 1.6rc5, this doesn't works. I think that creating draggables by demand could be a great enhacement. I know this can be done with the new live method on jquery, but creating draggables on mousedown is a better solution to avoid overhead.

After some research I have seen that I can do:

$(this).draggable().data('draggable')._mouseDown(e);

It's not too much friendly, but this works. Maybe some option on the draggable method could be introduced for this purpose.

Probably a regression.

It's a change that was needed in jQuery core, so jQuery core simply doesn't accept events being passed anymore as data. However, there's a new way of doing this, which is even simpler:

$('#draggable').one('mousedown', function(e) {

$("#draggable").draggable().trigger(e);

});

So you bind a onetime executed event to mousedown, and then simply retrigger the mousedown event using trigger(e) (that way you won't have an infinite recursion). This works like a charm!
