I made some changes but I still can't have the widget to output all the
integers coming from the STDIN. Only the first one is on the screen ! I will
appreciate if you could help me, thanks !
Here is a snipet of the code...

// GTK initializations 

 int main( int   argc, char *argv[] )
{
 
  /*  GTK widget setup */

unsigned int val;
char buf[5];

while(read(STDIN_FILENO, &val, sizeof(int)))  // here is my problem, I'm not
able to actually go through this while loop more than once or is there a way
to refresh the windows so their contents could also be refreshed(variables)?
{
	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); //just making sure i'm reading val
	

    // --------------------------------------------------------------------
    // Create text entry widget and modify.
    // --------------------------------------------------------------------

    text_entry_Widget = gtk_entry_new();

    gtk_widget_modify_text(text_entry_Widget, GTK_STATE_NORMAL,
&colorGreen);
    gtk_widget_modify_base(text_entry_Widget, GTK_STATE_NORMAL,
&colorBlack);

    GtkStyle *style = gtk_widget_get_style(text_entry_Widget);
    pango_font_description_set_weight(style->font_desc, PANGO_WEIGHT_BOLD);
    
    gtk_widget_modify_font(text_entry_Widget, style->font_desc);

    int        text_width = 5;           // Width of field in characters
    gtk_entry_set_width_chars(GTK_ENTRY(text_entry_Widget), text_width);

    gtk_editable_set_editable(GTK_EDITABLE(text_entry_Widget), FALSE);
    GTK_WIDGET_UNSET_FLAGS(text_entry_Widget, GTK_CAN_FOCUS);

    
    strcat(buf," V");                    // V for volts after the int
    gtk_entry_set_text(GTK_ENTRY(text_entry_Widget), buf); // output the int
value

   PangoFontDescription *font_desc = pango_font_description_from_string
