Hi All,
I've successfully enabled drag and drop in a QTreeWidget (code below).
When you drag an internal QTreeWidgetItem inside the tree, there are
some lines shown where the item goes when dropped. When a url is dragged
over the tree this isn't happening (just a '+' at the cursor).
Is it possible to show these lines while dragging a url (or something
else) over the tree?
And than of course put the new item at the correct position in the tree.
Note: When dragging an internal treeitem, the only type of mimedata that
is available is "application/x-qabstractitemmodeldatalist", but there
seems to be no such thing as a "qabstractitemmodeldatalist" in PySide.
kind regards
Robbert
