Program Plan Intro

Tree Age

Program Plan:

• • Import “Tkinter” module for creating the GUI programs.
• • Define the necessary named constants for creating the growth rings.
• • Define the class named “Treeclass”.
  • ○ Define “__init__()” method for “Treeclass” class:
    • ■ Create the main window using the “tkinter” module.
    • ■ Create a canvas widget.
    • ■ Create the ring1 using canvas widget using the “create_oval()” method.
    • ■ Specify the text on the ring created using the canvas widget using the “create_text()” method.
    • ■ Create the ring2 using canvas widget using the “create_oval()” method.
    • ■ Specify the text on the ring created using the canvas widget using the “create_text()” method.
    • ■ Create the ring3 using canvas widget using the “create_oval()” method.
    • ■ Specify the text on the ring created using the canvas widget using the “create_text()” method.
    • ■ Create the ring4 using canvas widget using the “create_oval()” method.
    • ■ Specify the text on the ring created using the canvas widget using the “create_text()” method.
    • ■ Create the ring5 using canvas widget using the “create_oval()” method.
    • ■ Specify the text on the ring created using the canvas widget using the “create_text()” method.
    • ■ Pack the canvas that is created using the “pack” method.
    • ■ Call the main loop using the “tkinter” module.
  • • Now, call the “Treeclass()” function.
