How to "Reveal in Finder" or "Show in Explorer" with Qt

Is it possible to open a folder in Windows Explorer/OS X Finder and then select/highlight one file in that folder, and do it in a cross platform way? Right now, I do something like

QDesktopServices::openUrl( QUrl::fromLocalFile( path ) );

where path is a full path to folder I want to open. Obviously, this will just open the folder, and I'll have to track down the file I need manually. This is a bit of a problem when there are thousands of files in that folder.

If I make it a path to specific file in that folder, then that file is open with default application for that mime type, and that is not what I need. Instead, I need the functionality equivalent to "Reveal in Finder" or "Show in Explorer".

This solution works on both Windows and Mac:

void showFileInFolder(const QString &path){
    #ifdef _WIN32    //Code for Windows
        QProcess::startDetached("explorer.exe", {"/select,", QDir::toNativeSeparators(path)});
    #elif defined(__APPLE__)    //Code for Mac
        QProcess::execute("/usr/bin/osascript", {"-e", "tell application \"Finder\" to reveal POSIX file \"" + path + "\""});
        QProcess::execute("/usr/bin/osascript", {"-e", "tell application \"Finder\" to activate"});
    #endif
}
