= Gimp::UI::FileSelection

This widget is used to enter filenames or directories.

There is a ((<Gtk::Entry>)) for entering the filename manually and a "..."
button which will pop up a ((<Gtk::FileSelection>)) dialog.

You can restrict the Gimp::FileSelection to directories. In this case the
filename listbox of the Gtk::FileSelection dialog will be hidden.

If you specify check_valid as TRUE in FileSelection#new() the entered
filename will be checked for validity and a pixmap will be shown which
indicates if the file exists or not.

Whenever the user changes the filename, the "filename_changed" signal will be
emitted.

== Class methods:

--- Gimp::UI::FileSelection.new(title, filename, dir_only = false, check_valid = false)
