I tried to follow your idea and this is what I did :
> main()
> {
> // I made ALL widgets necessary for program
>
> // enter while loop to read all values from stdin
unsigned int val;
char buf[5];
read(STDIN_FILENO, &val, sizeof(int)); //1st voltage not used
read(STDIN_FILENO, &val, sizeof(int)); //2nd voltage not used
while(read(STDIN_FILENO, &val, sizeof(int)))
{
char temp[5];
//read(STDIN_FILENO, &val, sizeof(int));
buf[0]=ita(val/100);
buf[1]=ita((val-((val/100)*100))/10);
buf[2]='.';
buf[3]=ita(val-((val/10)*10));
printf(" reading %d",val);
strcat(buf," V");
gtk_entry_set_text(GTK_ENTRY(text_entry_Widget), buf); // update text
into widget
read(STDIN_FILENO, &val, sizeof(int));
buf[0]=ita(val/100);
buf[1]=ita((val-((val/100)*100))/10);
buf[2]='.';
buf[3]=ita(val-((val/10)*10));
buf[4]='\0';
printf(" reading %d",val);
//volt insert
strcat(buf," V");
gtk_entry_set_text(GTK_ENTRY(text_entry_Widget2), buf); // update text
into widget
} //with the while loop closing here I have this error:
//(<unknown>:4436): Gtk-WARNING **: Attempting to add a widget with
type GtkVBox to a container of type GtkHBox, but the widget is already
inside a //container of type GtkHBox, the GTK+ FAQ at
http://www.gtk.org/faq/ explains how to reparent a widget.
gtk_widget_show_all (window);
gtk_main ();
// if I close the while loop here I only have one voltage output and it
can't refresh
return 0;

> }
I don't know if it has something to do with "reparent widget" function, I
tried to read about it but I don't get it...
Thanks, do you have any idea what could cause this ?
