Hello Bastien,
Weird that jquery looks at what the default drag handler does, but this
fixes it:
containerJq->doJavaScript("document.body.ondragstart=null;");
containerJq->doJavaScript("$('#" + containerJq->id() + "').draggable();");
The second doJavaScript call can replace that weird JSlot construction,
right?
Br,
Wim.
