Later on, we start processing positional arguments, but only if there is one. Otherwise, we proceed as usual. In our case we can only open one file at a time, so only the first file is of interest to us. We call the openFile() function and feed it the URL of the file we want to open, whether it is a local file like $HOME/foo or a remote one like ftp.mydomain.com/bar. We use the overloaded form of QUrl::fromUserInput() in order to set the current path. This is needed in order to work with relative paths like "../baz".
