Drag and drop Outlook mail in windows Gadget

Question

I drag mail message or mail message attachment from Outlook. What types parameter data put outlook in dataTransfer?

When drop is done in call function

function GetItemFromDrop() {
    var t1 = event.dataTransfer.files;
    var t2 = event.dataTransfer.types;
    var t3 = event.dataTransfer.items;
    var t4 = System.Shell.itemFromFileDrop(event.dataTransfer, intIndex);
}

In result: t1=t2=t3=t4=null

When dragging file from file system, all worked.
