Just can't get drag and drop to work

I’ve been experimenting with drag and drop for a few hours but I haven’t even been able to get a component draggable. I’m starting to think I’ve missed something fundamental?

Anyway, I decided to try out an example I found, see attached file. The result I get from that project is basically a button who just refuse to be dragged, even less be dropped somewhere. Is there some configuration I have to do the project itself to enable drag and drop?

Strange, I don’t see anything wrong with the code. I even imported the project and tried it, it works perfectly and I’m able to drag the Button around the AbsoluteLayout.

What browser are you using? Drag&Drop should work fine on all the supported browsers. Well, if the
book example
works for you, there shouldn’t be a problem with the browser.

Yay! I figured it out.

The project contained a widgetset which was configured to only compile against gecko:

Once I commented that out and recompiled the set, it all started working. This seems weird to me because I was testing my app in Firefox 3.6 all along.

I don’t know if this is the desired behavior or if it’s a bug, I leave that up to someone more talented than I to decide :slight_smile:

Thanks for your help which led to attack the problem from another angle.

This is odd. I tried with Firefox 3.5.9 and it worked fine. It may be that there’s something changed with the user agent detection in GWT 2.

I found this comment:

Firefox 3.6 uses Gecko 1.9.2, while 3.5 uses 1.9.1, so there’s no huge difference. In any case, try using “gecko1_8” and tell if it starts working. I added a
about the problem.

Yeah, you’re right, switching to gecko1_8 worked as supposed to.
