Re: How to set custom Gtk::FileFilter

[Kjell Ahlstedt <kjell ahlstedt bredband net>]

No, it does not use regex. If it did, the pattern would have been 
".*\.dat" instead of "*.dat".
The description,
https://developer.gnome.org/gtkmm/stable/classGtk_1_1FileFilter.html#a9b49e4a03afffc2806d17abf33b26cad
or, if you use gtkmm 2
https://developer.gnome.org/gtkmm/2.24/classGtk_1_1FileFilter.html#a9b49e4a03afffc2806d17abf33b26cad
says "Adds a rule allowing a shell style glob to a filter."
