GUI maintains a tour group size, which is initially set to 5. The
size is limited to a number between 5 and 25. The initial GUI is
shown in Figure Q4(a). When the user clicks on the button Add Pax,
the GUI adds the input number to the tour group size if the
resulting size does not exceed 25. The input field is cleared and
the GUI displays an appropriate message depending on whether the
add is successful.
Figure Q4(b) shows the GUI when the number 2 is added
successfully. The GUI displays a message including the number added
and the resulting group size.
Figure Q4(c) shows the GUI when the number 20 is not added
successfully. The GUI displays the reason for the number not being
added.
When the user clicks on the button Remove Pax, the GUI subtracts
the input number from the tour group size if the resulting size is
at least 5. The input field is cleared and the GUI displays an
appropriate message depending on whether the removal is
successful.
Figure Q4(d) shows the GUI when the number 2 is subtracted
from the group size successfully. The GUI displays a message
including the number removed and the resulting group size. Figure
Q4(e) shows the GUI when the number 1 is not subtracted
successfully. The GUI displays the reason for the number not being
subtracted.

events in accordance to the question specifications. Use the insert
method on the ScrolledText object to write into it. For example, if
the ScrolledText object is s, the statement writes the message
Hello on s: s.insert('end', 'Hello\n')
(c) Write Python statements to bind the relevant widgets
identified in Q4(a) to the callback functions in Q4(b).
