Before I go wasting the time implementing this myself, is there a way to have GTK auto scroll on the drop destination? Also, can it automatically expand a tree view? I've got a simple list being dragged onto a tree which works fine, but it doesn't auto scroll nor auto expand the tree.. I'm pretty sure there's enough bits a pieces around for me to try to do it myself, but it seems like something that should be built-in.

Oh, also I don't seem to be able to do a multi-select drag and drop. Whenever I try, it knocks the selection down to one item and goes from there.

Thanks!

Hrm, well partially figured out the multi-select drag and drop.. Seems that if you shift-select a bunch of rows, then do a separate click of the mouse to drag, it just selects that one item. If you shift-click-drag as one action, it works fine. Kinda of annoying, but at least there is one solution..

Hi,

On drop, after you've copied the dragged the content, you should still have the row and column of the place where the user dropped the content. With the row and column information,

1. Use the method
GtkTreeview::scroll_to_cell (path, [GtkTreeViewColumn column])
to do the auto scrolling.

2. Use GtkTreeView::expand_all()
or
GtkTreeView::expand_row(path)
to
expand the treeview.

Looks like I can hack together something with those methods. I was hoping there was just some flag I could set to make Gtk do it for me. :)
