Thus, the
Setup_gui
method is the main method used to set up the interface,
as shown here:
This is where you define which controls will be inserted and their arrangement,

2.
Spinner
: This is a color selector when clicked on so that you can choose a color.

: Instead of defining all of them individually,
a
for

each new button click event to a dedicated handler (
callback
). Let's take a look
at this callback method; it is shown in the following screenshot:
