Hi all, i saw examples on :
http://www.gtkmm.org/docs/gtkmm-2.4/docs/tutorial/html/ch08s07.html#id2501173 http://www.gtkmm.org/docs/gtkmm-2.4/docs/tutorial/html/ch15s05.html I want to use drag and drop in the same treeview like in the first link. There is 3 columns in my treemodel : col_id, col_name, col_select. I don't add col_id to the treeview because i don't want it to be visible but i use its value in order to know if i should accept drag or not. I have override the two methods: virtual bool row_draggable_vfunc(const Gtk::TreeModel::Path& path) const; virtual bool row_drop_possible_vfunc(const Gtk::TreeModel::Path& dest, const Gtk::SelectionData& selection_data) const; but i have difficulties to understand the dest value... In fact, i want that user can drop the selected row on row where col_id < 0 but not on row where col_id > 0. I try this : bool Dnd_TreeModel::row_drop_possible_vfunc(const Gtk::TreeModel::Path& dest, const Gtk::SelectionData& selection_data) const { Gtk::TreeModel::Path dest_parent = dest; Dnd_TreeModel* unconstThis = const_cast<Dnd_TreeModel*>(this); const_iterator iter_dest_parent = unconstThis->get_iter(dest_parent); if(iter_dest_parent) { Row row = *(iter_dest_parent); if( row[cols.col_id] < 0 ){ return true; }else return false; } return Gtk::TreeStore::row_drop_possible_vfunc(dest, selection_data); } but it doesn't work. Sometimes, i can drop row on row where col_id < 0. Do you have any idea to resolve my problem? I have also tried to connect my treeview with the signal_drag_data_received but in the callback, i can't find how to cancel the drag&drop... Thanks a lot in advance and sorry for my english! lm. _______________________________________________ gtkmm-list mailing list [email protected] http://mail.gnome.org/mailman/listinfo/gtkmm-list
