The signal_cursor_changed() signal works like a mouse click ---> GdkEventButton ev; (ev->type==GDK_BUTTON_PRESS)... useless If you have any idea, any advices, any examples or any links to documentation, you’re welcome :) Regards Marco Dos Santos Oliveira EBU/European Broadcasting Union Technology and Innovation Department From: gtkmm-list [mailto:gtkmm-list-bounces gnome org] On Behalf Of Dos Santos, Oliveira Hi everybody, Basically, How to properly implement the set_hover_selection(true) from the Gtk::TreeView Class with the set_mode(Gtk::SELECTION_MULTIPLE) from the Gtk::TreeSelection class ??? When I implement only the hover effect, it works fine and I have the expected effect on each row. set_hover_selection(true); // works fine When I implement only the multiple selection mode, it works fine and I can select several rows of my Gtk::TreeView at the same time. m_TreeViewSelection = get_selection(); m_TreeViewSelection->set_mode(Gtk::SELECTION_MULTIPLE); // works fine When I try to implement the both, only the multiple selection mode stays functional and the hover effect seems disable. set_hover_selection(true); // seems to be disable m_TreeViewSelection = get_selection(); m_TreeViewSelection->set_mode(Gtk::SELECTION_MULTIPLE); // works fine My source code compiles without problem or warnings. When I launch my application, all works fine; During operation, I have neither warning or neither crashes and all seems to be fine except the hover effect which doesn’t work. If it’s a bug which needs to be fixed, can I activate my hover effect with multiple selection if I connect the Glib::SignalProxy0<void> Gtk::TreeView::signal_cursor_changed(void) signal ???
