Changed all drag events to draggable handles

[blackshadev]

After I tried to monkey patch jquery draggable into slickgrid it seemed to work pretty well. In case people have problems with jquery.event.drag.js (as I did), this will remove that dependency within the core grid.

Thanks! I wish all the pull requests were this concise and to the point.

It looks like jquery.event.drop.js has been rolled into jQueryUI droppable as well. Any chance you could patch that one as well if you are familiar with it ? It's not in the grid, the only place it's used is in: example9-row-reordering.html

Give me a couple of minutes

:-)
I've been checking all the examples and removing the reference to jquery.event.drag.js. Examples all look all look OK except that one. Looks like even the dragging is busted.

Upon closer inspection this is somewhat less easy than expected. jquery.(drag|drop).event.js are actual events which propagate through the DOM (something which is used by the grid).

Draggable/droppable from jquery UI doesn't. I will look into it a bit more, but the normal D'n'D behaviour will break with my previous pull request.

[blackshadev]

From what I tell this isn't such a good idea to remove jquery.(drag|drop).event.js just yet, even though it is considered as legacy.
SlickGrid constructs a whole table row as a html string before appending it. This makes it hard to bind a draggable/droppable event to it.

To me it seems better if someone who knows more about the internals of SlickGrid takes a look at this. Stick with jquery.drag.event.js until then.

There is possibly a way to put the external libraries into a different namespace so they don't clash with jQueryUI. I might investigate that approach.

I've reverted the pull, actually deleted the history. I think I was quick enough that it won't affect anyone. Let's investigate some more.

You may be interested to know there's a clone of the drag&drop lib used by SlickGrid in https://github.com/GerHobbelt/jquery.threedubmedia ; I know we have a few very subtle issues with it regarding touch (on modern touchscreen+mouse desktops / laptops) when the DOM gets complex enough, but it might be something to try if only to see if that one will float your boat.

[6pac]

I'm interested, but I have to ask: why swap one additional dependency for another? I think we were hoping to find something built into jQuery or jQueryUI to do the job.
What differentiates your lib from the ThreeDub one ? Is it just more up to date ?

[GerHobbelt]

Just more up to date, 's all. We're using it here in our main app with jQuery v2.
