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();

Thanks

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.

Could you try again with the latest git?

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?

What OS are you using and which compiler?

Linux (Fedora) 64bit, DMD 2.063.1

Just upgraded to dmd 2.063.2 - no difference
