   NAME
       getfile_gc -- create getfile BOOPSI objects

   SUPERCLASS
       gadgetclass

   DESCRIPTION
       The getfile gadget class is used to get files and drawers from a file
       requester in an easy and consistent way.  It consists of two button
       gadgets, one read-only and one popfile/popdrawer button, that are
       used to select the file(s)/drawer and show the result.

       Advantages that this class provides:

       > Consistent behaviour and look in all applications using this class
         instead of doing their own file and drawer routines.

       > Easy to use.

                 the domain of the gadget.

                   of files.

    ATTRIBUTES

          Applicability is (OM_NEW, OM_SET).

       GETFILE_Filelist (struct List *)
          If the GETFILE_DoMultiSelect tags was used, you can get a pointer
          to the list of selected files/drawers using this tag. The ln_Name
          part of each node will contain the filename/drawername for each
          selected file with a fully qualified path, even if you didn't use
          the GETFILE_FullFileExpand.
          In single-selected mode, the list will contain the single selected
          file for notification purposes. Don't forget to free the list using
          the GFILE_FREELIST method! This list is not suitable to be shown
          directly in a listbrowser gadget without conversion as default, use
          GETFILE_LBNodeStruct for that.

          Applicability is (OM_GET, OM_NOTIFY).

       GETFILE_LBNodeStruct (BOOL)
          GETFILE_Filelist will give a list with ListBrowserNodes instead of
          normal struct Node node structures. NOTE: This tag requires that
          listbrowser.gadget is installed.

          Defaults to FALSE.

          Applicability is (OM_NEW).

          DO NOT USE THIS TAG YET SINCE SOME INTERNAL ISSUES HAVE NOT BEEN
          SORTED OUT YET!

       GETFILE_ReadOnly (BOOL)
          If TRUE, a read-only recessed button gadget is used to present the
          file/drawer information. If FALSE, an editable string gadget is used.
          The gadget will send the supported attributes in a OM_NOTIFY when a
          this tag is FALSE and the user is finished editing the content of the
          string gadget. The application can be aware of all changes to the
          string gadget by setting ICA_TARGET to TARGET_IDCMP for this
          getfile gadget instance and watching IDCMP_IDCMPUPDATE messages.
          See the provided example program for an example on how this can be
          done.

          Defaults to TRUE.

          Applicability is (OM_NEW).
