popup->triggered().connect(boost::bind(&Home::handlePopup, this,
WString::fromUTF8(l.path_)));
gives me this Error:
/usr/include/boost/bind/bind.hpp:313: error: no match for call to
'(boost::_mfi::mf1<void, Home, Wt::WString*>) (Home*&, Wt::WString&)'
unwrapper<F>::unwrap(f, 0)(a[base_type::a1_], a[base_type::a2_]);
It looks like the Template does not support Wt::WString, not sure how to
get this to work with a mouse event or bool signal, do you know of a
work around for this problem?
Is it possible to make WMenu work as a popup?
