I can use Gtk, Gdk namespace, but Gio doesn't work.
Below is the code where Gio is used:
void MyWindow::LoadAllFile(Glib::ustring dirPath)
{
if(curDir!=dirPath)
{
filenameArray.clear();
Glib::RefPtr<Gio::File> file=Gio::File::create_for_path (dirPath);
Glib::RefPtr<Gio::FileEnumerator> fileEnum=file->enumerate_children();
Glib::RefPtr<Gio::FileInfo> fileInfo;
while((fileInfo=fileEnum->next_file())!=NULL)
{
Glib::ustring filename=dirPath+"/"+fileInfo->get_name();
Glib::ustring suffix=filename.substr(filename.size()-3,3);
if(suffix=="jpg" || suffix=="bmp" || suffix=="png")
filenameArray.push_back(filename);
}
curDir=dirPath;
}
}
compile result:
