Re: Fwd: how do I delete a row in a Gtk::ListViewText

Sorry, you must do Yor_Model->erase(sel_it);
erase() comes from Gtk::ListStore and from Gtk::TreeModel.

my code now is:

Gtk::ListViewText::SelectionList sellst =
m_listviewtextAvailable->get_selected();
if(sellst.empty()) return;
Glib::RefPtr<Gtk::TreeSelection> ts =
m_listviewtextAvailable->get_selection();
Gtk::TreeModel::iterator sel_it = ts->get_selected();
int sel = sellst[0];
Glib::ustring selrow = m_listviewtextAvailable->get_text(sel);
//erase(sel_it);
*(m_listviewtextAvailable->get_model())->erase(sel_it);


and I get thye following compiler error:

/home/grizzlysmit/Projects/xmms2/cathy/src/dialog-new-playlist.cc:221:43: error:
‘class Gtk::TreeModel’ has no member named ‘erase’

what am I doing wrong :(

    For the selected row, use get_selection(), get_selected() and
    with the iterator returned by get_selected(), use erase(iterator).
    For an arbitrary row, iterate over the rows of your model with
    your_model->children().begin(), your_model->children().end(),
    etc. and use erase() on the iterator you want.

    umm where does the erase function come from, I did this

    Gtk::ListViewText::SelectionList sellst =
    m_listviewtextAvailable->get_selected();
    if(sellst.empty()) return;
    Gtk::TreeModel::iterator sel_it =
    m_listviewtextAvailable->get_selection()->get_selected();
    int sel = sellst[0];
    Glib::ustring selrow = m_listviewtextAvailable->get_text(sel);
    erase(sel_it);

    and I get a compile error on erase the compiler cannot find it??

        Yeah I have been trying to delete a row in a
        Gtk::ListViewText, but I
        cannot find a member function to do this, I have tried the
        following

        guint num_cols = get_num_columns();
        guint num_rows = size();
        Glib::ustring result;
        if(num_cols == 1){
        std::vector<Glib::ustring> tmp;
        for(int r = 0; r < num_rows; r++){
        if(r == row){
        result = get_text(r);
        }else{
        tmp.insert(tmp.end(), get_text(r));
        }
        }
        remove_all_columns();
        guint n = tmp.size();
        for(int r = 0; r < n; r++){
        append(tmp[r]);
        }
        }else{
        std::vector<std::vector<Glib::ustring> > tmp;
        std::vector<Glib::ustring> t;
        for(int r = 0; r < num_rows; r++){
        if(r == row){
        result = get_text(r);
        }else{
        t.insert(t.end(), get_text(r));
        for(int c = 1; c < num_cols; c++){
        t.insert(t.end(), get_text (r, c));
        }
        tmp.insert(tmp.end(), t);
        }
        }
        remove_all_columns();
        guint n = tmp.size();
        for(int r = 0; r < n; r++){
        guint _r = append(tmp[r][0]);
        guint m = tmp[r].size();
        for(int c = 1; c < num_cols && c < m; c++){
        set_text(_r, c, tmp[r][c]);
        }
        }
        }

        but the remove_all_columns(); is too drastic I loose every
        thing and can
        no longer put the rows I want to keep back as append stops
        working as I
        have no columns any more I'd really appreciate some help on
        this thx
