如何將相對路徑轉換爲C++和gtk下的絕對路徑？

Answer 1

// For C++ with Gnome Gtkmm3 libraries 
#include <string> 
#include <glibmm.h> 
#include <giomm.h> 

using namespace std; 

string PathRel2Abs(string relpath) { 
    Glib::RefPtr<Gio::File> file = Gio::File::create_for_path(relpath); 
    return file->get_path(); 
}
