The first step is asking the user for the name of the file to
open. Qt comes with QFileDialog, which is a dialog from which the
user can select a file. The image above shows the dialog on
Kubuntu. The static \l{QFileDialog::}{getOpenFileName()} function
- displays a modal file dialog, and does not return until the user
- has selected a file. It returns the file path of the file

selected, or an empty string if the user canceled the dialog.

Now, let us move on to the the \c save() slot.
