Example

The following function, HyperlinkCB(), illustrates the general structure needed to handle hyperlink callbacks.

XtCallbackProc
HyperlinkCB (widget, clientData, callData)
      Widget     widget;
      XtPointer  clientData;
      XtPointer  callData;
   {
      DtHelpDialogCallbackStruct *hyperData =
         (DtHelpDialogCallbackStruct *) callData;
      switch ((int)hyperData-> hyperType)
         {
            case DtHELP_LINK_TOPIC:
              /* Handles  "jump new view"hyperlinks. */
              break;
            case DtHELP_LINK_MAN_PAGE:
              /* Handles  "man page" hyperlinks. */
              break;
            case DtHELP_LINK_APP_DEFINE:
              /* Handles ``application-defined" hyperlinks. */
              break;
            case DtHELP_LINK_TEXT_FILE:
              /* Handles ``text file" hyperlinks. */
              break;
            default:
              break;
    }
