Re: Get gchar* from Glib::ustring

[Fabrício Godoy <skarllot gmail com>]

Thank you.

Can you say why the following code compile but don't work?


template <class T1, class T2, class T3>

Glib::ustring build_filename(const T1& str1, const T2& str2, const T3& str3)
{

    Glib::ustring ustr1 = Glib::ustring::compose("%1", str1);
    Glib::ustring ustr2 = Glib::ustring::compose("%1", str2);

    Glib::ustring ustr3 = Glib::ustring::compose("%1", str3);


    gchar* path;

    path = g_build_filename(ustr1.c_str(), ustr2.c_str(), ustr3.c_str());

    Glib::ustring r_path(path);
    g_free(path);

    return r_path;
}

You can just use the Glib::ustring member functions data() or c_str()
[1], the returned char* is basically the same as gchar* [2].
