Hi Guillaume,
Thanks for the fast reply...
I know that the Gtk::Widget don't have the set_active() member but as
it is pointing to a ToggleButton widget, isn't it possible to use the
method?
I there a someway to make the pointer accept the method?
You can cast the pointer to obtain a "Gtk::ToggleButton *" using
"dynamic_cast" c++ operator. The code may look like this :
dynamic_cast< Gtk::ToggleButton* >( ptrElement )->set_active(true);
But, you must be aware that "dynamic_cast" will return a null pointer if
ptrElement does not point to a Gtk::ToggleButton (or derived) instance.
You should then check the pointer prior call "set_active".
Guillaume
