I'm trying to get a TreeStore object back out of a TreeView in 
GtkD.

The reason for this is so that I can change the value of a cell 
in the TreeView - in this case changing one image for another.

I can't use a TreeModel for this as it does not have a setValue 
function.

I've got this working with the following code:

private bool tvTreeView_ButtonRelease(Event e, Widget sender) {
   TreeIter selectedItem = tvTreeView.getSelectedIter();
   TreeStore store = new 
TreeStore(cast(GtkTreeStore*)selectedItem.gtkTreeModel);

   store.setValue(selectedItem, 2, newPixbuf);
}

But this seems like a really ugly way to do this, I'm sure I'm 
missing something.

I've also tried:

TreeStore store = 
ObjectG.getDObject!(TreeStore)(cast(GtkTreeStore*)selectedItem.gtkTreeModel);
This creates a TreeModel not a TreeStore

TreeStore store = cast(TreeStore)tvTreeView.getModel();
In this case store == null

Does anyone know a better way of doing this?
Or is this something missing from GtkD?

Thanks

I think that one should work, how are you setting/creating the TreeStore?

tvTreeView.setModel(CreateModel());

private TreeStore CreateModel()
{
   TreeStore treeStore = new TreeStore([GType.STRING, 
GType.STRING, Pixbuf.getType()]);

   Values a filled recursively using treeStore.setValue(iter, 
column, value);
}

getModel returns an interface, so try the following:

TreeStore store = cast(TreeStore)cast(void*)tv.getModel();

Ok, just tried this and after setting store if I call
writeln(store) the output is what looks like a memory dump,
definitly something wrong there.
And the program crashes if I try to use store.

OK, I pulled the changes and rebuilt gtkd but the error is still 
the same.

I tried all the variations in code listed in my first post, plus 
the one you suggested with the double cast, but everything failed 
in the same ways as before.

On the plus side, nothing new broke - it still works with the 
work-around way I've got.

Is there any more info I can supply that would help you?

Yes, and I did writeln(store) and the result was a treestore so 
this code works fine.

Yet still my code doesn't work even though it's effectively doing 
the same thing, kind of weird.
