            | Issue | How do I define the event type when I use PtAddCallback() to assign a raw callback? 
 |  
            | Solution | This can be set up in the PtRawCallback_t structure. It contains: 
 event_mask --> events which trigger the given function
 event_f --> callback function
 data --> data passed to callback function
 
 Take a look at PtWidget in the widget reference and note that Pt_CB_RAW takes the above structure.
