For example, the following creates a canvas on a window: import tkinter as tkĬanvas = tk.Canvas(root, width= 600, height= 400, bg= 'white')Ĭanvas.pack(anchor=tk.CENTER, expand= True) To create a canvas widget, you create a new instance of the Canvas class from the tkinter module. The canvas widget is a blank area on which you can draw figures, create text, and place images. The Canvas widget allows you to build anything from custom widgets to complete user interfaces. The canvas widget is the most flexible widget in Tkinter. Introduction to the Tkinter canvas widget Select_record_button.Summary: in this tutorial, you’ll learn about the Tkinter Canvas widget and how to draw various objects on it. Select_record_button = Button(button_frame, text="Clear Entry Boxes", command=clear_entries) Move_down_button = Button(button_frame, text="Move Down", command=down) Move_up_button = Button(button_frame, text="Move Up", command=up) Remove_many_button = Button(button_frame, text="Remove Many Selected", command=remove_many) Remove_one_button = Button(button_frame, text="Remove One Selected", command=remove_one) Remove_all_button = Button(button_frame, text="Remove All Records", command=remove_all) Update_button = Button(button_frame, text="Update Record", command=update_record) My_em(selected, text="", values=(fn_entry.get(), ln_entry.get(), id_entry.get(), address_entry.get(), city_entry.get(), state_entry.get(), zipcode_entry.get(),))īutton_frame = LabelFrame(root, text="Commands")īutton_frame.pack(fill="x", expand="yes", padx=20) My_tree.move(row, my_tree.parent(row), my_tree.index(row)+1) My_tree.move(row, my_tree.parent(row), my_tree.index(row)-1) Zipcode_label = Label(data_frame, text="Zipcode") State_label = Label(data_frame, text="State") Ln_label = Label(data_frame, text="Last Name") My_tree.insert(parent='', index='end', iid=count, text='', values=(record, record, record, record, record, record, record), tags=('oddrow',))ĭata_frame = LabelFrame(root, text="Record")ĭata_frame.pack(fill="x", expand="yes", padx=20)įn_label = Label(data_frame, text="First Name")įn_id(row=0, column=0, padx=10, pady=10)įn_id(row=0, column=1, padx=10, pady=10) My_tree.insert(parent='', index='end', iid=count, text='', values=(record, record, record, record, record, record, record), tags=('evenrow',)) My_tree.tag_configure('evenrow', background="lightblue") My_tree.tag_configure('oddrow', background="white") My_tree.heading("Zipcode", text="Zipcode", anchor=CENTER) My_tree.heading("State", text="State", anchor=CENTER) My_tree.heading("City", text="City", anchor=CENTER) My_tree.heading("Address", text="Address", anchor=CENTER) My_tree.heading("ID", text="ID", anchor=CENTER) My_tree.heading("Last Name", text="Last Name", anchor=W) My_tree.heading("First Name", text="First Name", anchor=W) My_lumn("Zipcode", anchor=CENTER, width=140) My_lumn("State", anchor=CENTER, width=140) My_lumn("City", anchor=CENTER, width=140) My_lumn("Address", anchor=CENTER, width=140) My_lumn("Last Name", anchor=W, width=140) My_lumn("First Name", anchor=W, width=140) My_tree = ("First Name", "Last Name", "ID", "Address", "City", "State", "Zipcode") My_tree = ttk.Treeview(tree_frame, yscrollcommand=tree_t, selectmode="extended") We’ll also add the ability to move records up or down in the treeview panel. We’ll write the code for Selecting records, updating records, Removing all records, removing one record, and removing many records. In this video we’ll add some functionality to our treeview app.
