Message definition (Development/Tutorials/CommandLineArguments)

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 <tt>openFile()</tt> function and feed it the URL of the file we want to open, whether it is a local file like {{path|$HOME/foo}} or a remote one like {{path|ftp.mydomain.com/bar}}. We use the overloaded form of <tt>[http://doc.qt.io/qt-5/qurl.html#fromUserInput-1 QUrl::fromUserInput()]</tt> in order to set the current path. This is needed in order to work with relative paths like <tt>"../baz"</tt>.
