.. _set_on_tp_progress:

set_on_tp_progress
------------------------------------------
This function is used to register the callback function to check the information  
of the execution step when the ``tp_progress`` command is used in DRL.  
It is useful when functions that should be executed automatically are made.

**Definition** |br|
``DRFLEx.h`` within class `CDRFLEx`, public section (line 643) 

.. code-block:: cpp

    void set_on_tp_progress(TOnTpProgressCB pCallbackFunc) { 
        _set_on_tp_progress(_rbtCtrl, pCallbackFunc); 
    };

**Parameter**

**Example**

.. code-block:: cpp

   // Callback function for TP progress updates
   void OnTpProgress(LPMESSAGE_PROGRESS tProgress)
   {
       printf("-------------------------------------------\n");
       printf("[TP PROGRESS UPDATE]\n");
       printf("Current Step : %d / %d\n", tProgress->_iCurrentCount, tProgress->_iTotalCount);
       printf("Progress (%%) : %d%%\n", tProgress->_iPercent);
       printf("Description  : %s\n", tProgress->_szDesc);
       printf("-------------------------------------------\n");

       // Example: stop process when 100% complete
       if (tProgress->_iPercent >= 100)
           printf("[Host] Operation completed successfully.\n");
   }

   // Register the progress callback
   drfl.set_on_tp_progress(OnTpProgress);

   printf("Monitoring TP progress updates...\n");
   while (true)
   {
       this_thread::sleep_for(chrono::seconds(1));
   }

When registered, this callback function executes automatically  
when a **progress message** is reported from the Teach Pendant (TP).  
It helps track **execution steps, percentage, and status messages**  
to provide live task progress monitoring.
