Okay,
So how do I retrieve the folder URI from the drop event?
1st, is "text/x-moz-folder" the correct type for dragging the smart folder:
var msgFolder = evt.dataTransfer.mozGetDataAt("text/x-moz-folder", 0);
I tried msgFolder.getURI() but that doesn't return anything.
I can not find any interfaces in the debugger, is it possible to
typecast to nsMsgLocalMailFolder or convert to a nsMsgLocalMailFolder?
I am only used to C++ style type casts, so how would I do it in
Javascript? Bear with me as I don't really know when to use a var and
when an object(?) typeless programming is always a bit of a gamble to me.
Also while we're on the topic of dragging folders, (in TB3) there
appears also a drop event on dragged newsgroup folders, any chance to
get at their folder URI? Or is this a bug and dragging won't be
supported for NG folders in the final release?
sorry for asking so many Questions, Questions...
thanks in advance

I tried
var msgFolder = evt.dataTransfer.mozGetDataAt("text/x-moz-folder", 0);
sourceUri =
msgFolder.QueryInterface(Components.interfaces.nsIMsgFolder).URI;
- seems to do the trick - need to test with SM and Pb yet.
Last question regarding Smart Folders: when selecting a Smart Folder
there is no FOlderLoaded event - is there any other event that I could
catch? I need to highlight the select SmartFolder on my extension's toolbar.

Debugging a drop event for NG to my toolbar threw this error:
Error: transferData.first is null
Source file: chrome://global/content/nsDragAndDrop.js
Line: 459
its thrown when trying to call transferData.first.first:
var multiple =
"canHandleMultipleItems" in
aDragDropObserver && aDragDropObserver.canHandleMultipleItems;
-> var dropData = multiple ? transferData : transferData.first.first;
aDragDropObserver.onDrop(aEvent, dropData, this.mDragSession);
aEvent.stopPropagation();
thanks in advance

The code here might give you some ideas:

folder tree, they are parents of the children, but by URI, the account
nodes are still the "real" parents - this leads to bugs in selectFolder
and ensureRowIsVisible. I am currently trying to deal with the fallout
of these bugs by programming a work-around in my extension.
