        Software documentation for the NSOpenPanel class

          <p>
            Implements a panel that allows the user to
            select a file or files. NSOpenPanel is based on the
            NSSavePanel implementation and shares a lot of
            similarities with it.
          </p>
          <p>
            There is only one open panel per application and this
            panel is obtained by calling the
            <ref type="method" id="+openPanel">
              +openPanel
            </ref>
            class method. From here, you should set the
            characteristics of the file selection
            mechanism using the
            <ref type="method" id="-setCanChooseFiles:">
              -setCanChooseFiles:
            </ref>
            ,
            <ref type="method" id="-setCanChooseDirectories:">
              -setCanChooseDirectories:
            </ref>
            and
            <ref type="method" id="-setAllowsMultipleSelection:">
              -setAllowsMultipleSelection:
            </ref>
            methods. The default is <code>YES</code> except
            for allowing multiple selection. When ready to show the
            panel, use the
            <ref type="method" id="-runModalForTypes:">
              -runModalForTypes:
            </ref>
            , or a similar method to show the panel in a modal
            session. Other methods allow you to set the
            initial directory and initially selected file. The
            method will return one of NSOKButton or
            NSCancelButton depending on which button the
            user pressed.
          </p>
          <p>
            Use the
            <ref type="method" id="-filename" class="NSSavePanel">
              [NSSavePanel -filename]
            </ref>
            or <ref type="method" id="-filenames">-filenames</ref>
            method to retrieve the name of the file the user
            selected.
          </p>
