If you tried my example from the last post:

then, as I said, it will of course only show the last element in the
queue; to handle multiple queue items you might for example add a
variable to process_serial() as in:
def process_serial(self):
firstitem = True
while self.queue.qsize():
try:
new = self.queue.get()
if firstitem:
self.text.delete(1.0, 'end')
firstitem = False
self.text.insert('end', new)
except Queue.Empty:
pass
self.after(1500, self.process_serial)
