Hi ! I`m not quiet sure if my previous mail was sent, so I`ll try to write it once again. Lieven van der Heide wrote, that I should call all gtk functions from one thread. I`ve tried : 1. Created function in main program, that calls gtk_label_set_text (). The function takes string as a ( from <string> ) parameter, which is converted to c-language string by string. c_str () 2. Thread function gets pointer to function from point 1. as a parameter, and when specific conditions arefulfilled, then the function from point 1. is beiung called ( by the pointer passed as an argument for thread function ) Result : the same :/ Any clues ? :) regards ---------------------------------------------------------------------- PS.
