      org.freedesktop.portal.FileChooser:
      @short_description: File chooser portal

The FileChooser portal allows sandboxed applications to ask
      the user for access to files outside the sandbox. The portal
      backend will present the user with a file chooser dialog.

The selected files will be made accessible to the application
      via the document portal, and the returned URI will point
      into the document portal fuse filesystem in /run/user/$UID/doc/.

This documentation describes version 3 of this interface.

          <term>filters a(sa(us))</term>
          <listitem>
            <para>
              List of serialized file filters.
            </para>
            <para>
              Each item in the array specifies a single filter to offer to the user.
              The first string is a user-visible name for the filter. The a(us)
              specifies a list of filter strings, which can be either a glob-style pattern
              (indicated by 0) or a mimetype (indicated by 1). Patterns are case-sensitive.
              To match different capitalizations of, e.g. '*.ico', use a pattern like
              '*.[iI][cC][oO]'.
            </para>
            <para>
              Example: [('Images', [(0, '*.ico'), (1, 'image/png')]), ('Text', [(0, '*.txt')])]
            </para>
            <para>
              Note that filters are purely there to aid the user in making a useful selection.
              The portal may still allow the user to select files that don't match any filter
              criteria, and applications must be prepared to handle that.
            </para>

        <varlistentry>
          <term>current_filter (sa(us))</term>
          <listitem><para>
            Request that this filter be set by default at dialog creation. If
            the filters list is nonempty, it should match a filter in the
            list to set the default filter from the list. Alternatively, it
            may be specified when the list is empty to apply the filter
            unconditionally.

          <term>choices a(ssa(ss)s)</term>
          <listitem>
            <para>
              List of serialized combo boxes to add to the file chooser.
            </para>
            <para>
              For each element, the first string is an ID that will be returned
              with the response, the second string is a user-visible label. The
              a(ss) is the list of choices, each being an ID and a
              user-visible label. The final string is the initial selection,
              or "", to let the portal decide which choice will be initially selected.
              None of the strings, except for the initial selection, should be empty.
            </para>
            <para>
              As a special case, passing an empty array for the list of choices
              indicates a boolean choice that is typically displayed as a check
              button, using "true" and "false" as the choices.
            </para>
            <para>
              Example: [('encoding', 'Encoding', [('utf8', 'Unicode (UTF-8)'), ('latin15', 'Western')], 'latin15'), ('reencode', 'Reencode', [], 'false')]
