Hello Nandan, I meant that you should provide a default event handler for unhandled cases ONLY when you already have an event handler function. Otherwise GUIX should use the default function. Are you checking return value from the functions you're calling? It's possible that your search will not return a GX_PROMPT pointer, in which case the following functions will all return a pointer error. Also, try replacing gx_widget_find with gx_system_widget_find, which is a global search: gx_system_widget_find(prompt_id_1, GX_SEARCH_DEPTH_INFINITE, (GX_WIDGET **) &prompt); I can follow up with an example shortly but I need to know which board you're using. Regards
