QT: Launch default exporer on a directory selecting a file

My application displays a grid of images. When the right mouse button is clicked a context menu is displayed where the first option is "Show in Explorer".

I was able to launch the default explorer on the directory by using:

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

However I want also the file to be selected.

Is this possible? I suppose it should be, as many apps can do that.

Ok, I want to thank @Chernobyl for his useful help.

However I've found a general solution posted here: How to "Reveal in Finder" or "Show in Explorer" with Qt

It wasn't compiling at first because the QtCreator code is using a class called Environment which I tried to add to my project but that file then also includes others, etc. I checked and they are using it just to see if explorer.exe can be found on the system path. It was not so important (to me) so I removed that check and then I tested it. It's working perfectly. It's also supposed to work for Mac and Linux.

openUrl is not suitable here. You need just start another process (with QProcess start or startDetached) with Windows explorer special arguments:

explorer.exe /select,"C:\pathTo\file.txt"
