graphical interface elements

Study the three tkinter properties presented below and see if you can
match up the properties to the correct description:

WM_TAKE_FOCUS A message sent to your main window
when the operating system is shutting
down

WM_SAVE_YOURSELF A message sent to your main window
when the close box has been clicked

WM_DELETE_WINDOW A message sent to your main window
when the window has been selected
after a mouse click

Which of these protocol messages do you think you need to capture?

window. These are known as Window Manager
protocol properties. Think of the event as a
