Hi all,
I'm tring to use a TreeView and I have some problem updating the list
0) I create ColumnRecord
class TreeCashColumns : public Gtk::TreeModel::ColumnRecord {
public:
Gtk::TreeModelColumn<Glib::ustring> m_Col1;
TreeCashColumns() {
add(m_Col1);
}
}
//Member Variable
TreeCashColumns m_Columns;
1) I create the ListStore model
m_TreeModel = Gtk::ListStore::create(m_Columns);
2) I Add columns to the view
TreeViewCashes->append_column("Col1",m_Columns.m_Col1);
3) I add rows
Gtk::TreeModel::Row row = *( m_TreeModel ->append());
row[m_Columns.m_Col1] = "Col1";
4) I set the model
TreeViewCashes->set_model( m_Model);
I don't understand why the function TreeView::set_model deferences the model
pointer (I see source code after a segfault), so that after such call
m_Model is no more valid.
If I need to refresh the rows, I cannot use m_Model because it was
deferenced, and I cannot find a way to get ListStore from TreeView.
I solved creating a new model but I don't think this is a good solution.
TreeView::get_model return only the base class TreeModel that don't have
clear() method to clear all rows.
Where am I wrong?
Thanks in advance.
Marco
