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 :( > > Greetings. > > > 2013/5/27 Francis (Grizzly) Smit <[email protected] > <mailto:[email protected]>> > > On 27/05/13 17:20, Juan Angel Moreno wrote: >> 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?? > > >> >> Greetings >> >> >> 2013/5/27 Francis (Grizzly) Smit <[email protected] >> <mailto:[email protected]>> >> >> 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 >> >> >> >> -- >> >> >> .~.
