if I let the append retunr a 'iterator' I can't adjust the value of the columns anymore, like: 'row[column] = "blabla". And I don't find how to get the row from a iterator or vice versa.Hi guys could somebody help me? In a treeview, when I populate it, I want a particular row selected(during the populating i think) and also i wane have itexpandedso I can see the underlaying targets but I can't find out how to dothis.hi it seems to me that if you append/insert/prepend a row to the treestore you get an iterator as return value... using this iterator it should be simple to get everything else you'd need. Something along the lines of: Gtk::TreeModel::iterator iter = mrefTreeStore->append(); Gtk::TreeModel::Path path = mrefTreeStore->get_path( iter ); Glib::RefPtr<Gtk::TreeSelection> refSelection = mTreeView->get_selection(); refSelection->select( path ); But perhaps you don't even need to do it half so complicated: http://www.gtkmm.org/docs/gtkmm-2.4/docs/reference/html/classGtk_1_1TreeSelection.html#a21 you can pass iterators, rows or paths to the TreeSelection object, no need to do any conversions between them just to select a row! If you want to expand the node you need the path anyway, so you can use the first code fragment I posted. If you want to expand a row you have to use mTreeView->expand_row( path, [true|false] ); http://www.gtkmm.org/docs/gtkmm-2.4/docs/reference/html/classGtk_1_1TreeView.html#a60 hth _______________________________________________ gtkmm-list mailing list gtkmm-list gnome org http://mail.gnome.org/mailman/listinfo/gtkmm-list
also the function you use here, 'mrefTreeStore->get_path( iter )' that function isn't documantated od did I overlook it?
thx for your help, Bart
