Dear List,
I am a new user to the gtk-sharp package and I am having some dificulties with
the TreeStore object.
After I created my object as:
store = new TreeStore(typeof(object));
I attach it to the TreeView.model as
treeViewer.Model = store;
And also I associate the RowInserted event to a method where I would like to
retrieve the item inserted like in:
store.RowInserted += delegate(object o, RowInsertedArgs args) {
TreeStore _store = (TreeStore) o;
object assoc_obj = _store.GetValue(args.Iter, 0);
if (assoc_obj == null){
throw new Exception("Invalid Object inserted into the tree.");
}
};
When I run my code the Exception is alway throw. Why does I cannot retrieve the
object ? It looks like that when I run the following command:
TreeIter it = store.AppendValues(ss);
to insert the object into the store the row is created empty, the event is
triggered and after that the object ss is attached to the row because I managed
to fetch the object from the RowChanged event (that by the way is triggered for
every object I insert if i create the store with more than one place to put
objects). Is this the correct behaiviour ? There is someway to control when the
event is triggered ? Some flags on the TreeStore ?
I appreciate any comments,
with my best regards,
Marcelo Bianchi
