标题: UG/Open对话框调用的心得二(含疑问，请ZZZ及各位大侠指点一下）
这次以UG提供的UG\help中的uf_sample_app.c为例进行说明，为了便于理解，仅对程序中的第二项回调函数SAMPLE_APP__action2进行分析，程序段如下：

static void SAMPLE_APP__enter( void );
static void SAMPLE_APP__init( void );
static void SAMPLE_APP__exit( void );

static UF_MB_cb_status_t SAMPLE_APP__action2(
UF_MB_widget_t          widget,
UF_MB_data_t             client_data,
UF_MB_activated_button_p_t call_button );

static int app_id = 0;

static UF_MB_action_t actionTable[] =
{
{ "SAMPLE_APP__action2", SAMPLE_APP__action2, NULL },
{ NULL, NULL, NULL }
};
static void print_error(char*fun, int status);

extern void ufsta( char *param, int *returnCode, int rlen )
{
UF_MB_application_t appData;
char name[] = "SAMPLE_APP";
int status;
int ifail=0;
         /* Initialize the API environment */
ifail= UF_initialize();

if ( !ifail )
{
      status = UF_MB_add_actions( actionTable );
      /* TODO: Add your application code here */
      /* Initialize application data */
      appData.name    = name;
      appData.id       = 0;
      appData.init_proc  = SAMPLE_APP__init;
      appData.exit_proc  = SAMPLE_APP__exit;
      appData.enter_proc = SAMPLE_APP__enter;
      /* Initialize application support flags */
      appData.drawings_supported       = TRUE;
      appData.design_in_context_supported = TRUE;
      /* Register the application with UG */

      status = UF_MB_register_application( &appData );
      app_id=appData.id;
      /* Terminate the API environment */
      //errorCode = UF_terminate();
}

      else
      {
      char message[133];
      UF_get_fail_message( ifail, message );

      /* Print out the message */
      UF_UI_set_status( message );

      fprintf( stderr, "%s\n", message );

      }

ifail = UF_terminate();
}
/*****************************************************************************

//extern int ufusr_ask_unload( void )
//{
// return( UF_UNLOAD_IMMEDIATELY );
//}

static void print_error( char *fun, int status )
{
if ( status != 0 )
{
      char msg[133];

      UF_get_fail_message( status, msg );
      printf( "%s failed with error = %d\n  %s\n", fun, status, msg );
}
}

static void SAMPLE_APP__enter( void)
{
printf( "Entering application\n" );

/* Place code to enter application here */
}

static void SAMPLE_APP__init( void )
{
printf( "Initializing application\n" );

/* Place code to initialize application here */
}

static void SAMPLE_APP__exit( void )
{

/* Place code to cleanup for application and exit here */
}

{
   char options[5][38] = { "UF_MB_CB_CONTINUE",

         printf( " Response = \"%s\" (%d)\n",
         ( response == 1 ? "Back" : "Cancel" ), response );
         break;

      case 5:
         cb_value = UF_MB_CB_CONTINUE;
         break;

      case 6:
         cb_value = UF_MB_CB_CANCEL;
         break;

      case 7:

         break;

      case 8:
         cb_value = UF_MB_CB_WARNING;
         break;

      case 9:
         cb_value = UF_MB_CB_ERROR;
         break;

      default:
         cb_value = UF_MB_CB_ERROR;
         printf( " Response = \"%s\" (%d)\n", "Unexpected", response );
         sprintf(msg, "Response number is %d",response);
         UF_UI_lock_ug_access( UF_UI_FROM_CUSTOM );
         uc1601( msg, 1 );
         UF_UI_unlock_ug_access( UF_UI_FROM_CUSTOM );
         break;
}

printf( "Return = %s\n", options[response - 5][0] );
return( cb_value );
}

其启动菜单按如下设置：

出了点出问题,后面再接着发,请大家稍微等等了.....
