<p>A <a class="el" href="classGtk_1_1FileFilter.html" title="A filter for selecting a file subset.

">Gtk::FileChooser</a>. Files can be filtered based on their name (with <a class="el" href="classGtk_1_1FileFilter.html#a9b49e4a03afffc2806d17abf33b26cad" title="Adds a rule allowing a shell style glob to a filter.

<p>Filtering by mime types handles aliasing and subclassing of mime types; e.g. a filter for text/plain also matches a file with mime type application/rtf, since application/rtf is a subclass of text/plain. Note that <a class="el" href="classGtk_1_1FileFilter.html" title="A filter for selecting a file subset. ">Gtk::FileFilter</a> allows wildcards for the subtype of a mime type, so you can e.g. filter for image/*.</p>
