Hi Fridrich,
I am a little bit confused as rtl::OUString provides an operator< as the
code from Shizhoubo works. See the declaration/implementation from
ustring.hxx below)
friend sal_Bool operator < ( const OUString& rStr1, const OUString&
rStr2 ) SAL_THROW(()) { return rStr1.compareTo( rStr2 ) < 0; }
Besides that you are right that a function object (functor) makes sense
as we don't want to use the built-in less-operator as it's not I18N
aware. That's why the original code uses vcl::I18nHelper to compare the
strings.
Regards,
Carsten
