</h1><div class="doc"><p>A <code><a href="Graphics-UI-Gtk-Selectors-FileFilter.html#t:FileFilter">FileFilter</a></code> can be used to restrict the files being shown in a
<code><a href="Graphics-UI-Gtk-Selectors-FileChooser.html#t:FileChooser">FileChooser</a></code>. Files can be filtered based on their name (with
<code><a href="Graphics-UI-Gtk-Selectors-FileFilter.html#v:fileFilterAddPattern">fileFilterAddPattern</a></code>), on their mime type (with <code><a href="Graphics-UI-Gtk-Selectors-FileFilter.html#v:fileFilterAddMimeType">fileFilterAddMimeType</a></code>),
or by a custom filter function (with <code><a href="Graphics-UI-Gtk-Selectors-FileFilter.html#v:fileFilterAddCustom">fileFilterAddCustom</a></code>).
</p><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 <code><a href="Graphics-UI-Gtk-Selectors-FileFilter.html#t:FileFilter">FileFilter</a></code> allows wildcards for the subtype of
a mime type, so you can e.g. filter for "image/*".
</p><p>Normally, filters are used by adding them to a <code><a href="Graphics-UI-Gtk-Selectors-FileChooser.html#t:FileChooser">FileChooser</a></code>, see
<code>Graphics.UI.Gtk.Selectors.FileChooser.fileChooserAddFilter</code>.
