says: "Hover selection makes the selected row follow the pointer.
Currently, this works only for the selection modes Gtk::SELECTION_SINGLE
and Gtk::SELECTION_BROWSE."

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

*Subject:* How to implement the hover effect with multiple selection
mode in a TreeView
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 ???
