Tkinter Cheat Sheet The most popular GUI creation tool for Python, Tkinter provides a number of widgets and methods you can use to create a user interface for your application. Position Widgets using pack(), place() or grid() pack() organizes widgets in horizontal and vertical boxes that are limited to left, right, top, bottom positions. Each box is offset and relative to each other. root.geometry(‘200x100’) test = tk.Label(root, text=”pack(side=tk.bottom)”, bg=”teal”) test.pack(side=tk.bottom) Tkinter Widgets Code Widgets from tkinter import * Button instance = Button(root, text="Click me!", ...) Combobox instance = ttk.Combobox(master, option=value, ...) Checkbutton instance = tk.Checkbutton(parent, option, ... ) Notebook instance = ttk.Notebook(container, options, ... ) Entry instance = tk.Entry(master, option, ...) Frame instance = Frame(parent, option, ...) Label instance = tk.Label(text="some text") LabelFrame instance = LabelFrame( master, option, ... ) Menubutton instance = Menubutton ( master, options, ... ) PanedWindow instance = PanedWindow(master, options, ... ) Radiobutton instance = Radiobutton(master, options, ... ) Scale instance = Scale (master, option, ... ) Scrollbar instance = Scrollbar ( master, options, ... ) Options: padx pads externally along the x axis pady pads externally along the y axis ipadx pads internally along the x axis ipady pads internally along the y axis from tkinter import * from tkinter.ttk import * pack(side=tk.bottom) place() places widgets in a two dimensional grid using x and y absolute coordinates. Progressbar instance = Progressbar(parent, options, ... ) Separator # orient options are 'horizontal' or 'vertical': instance = ttk.Separator(container,orient=' horizontal') Sizegrip instance = ttk.Sizegrip(master, options, ... ) Treeview instance = ttk.Treeview(master, options, ... ) root.geometry(‘200x100’) Label(root, text=”place(x=5, y=2)”, bg=”#A3DBE0”).place(x=5, y=2) grid() locates widgets in a two dimensional grid using row and column absolute coordinates. root.geometry(‘200x100’) Label(root, text=”grid(row=2, column=2)”, width=12).grid(row=2, column=2) 5 4 3 grid(row=2,column=2) place(x=5,y=2) 2 1 1 2 3 4 5 6 7 8 Tkinter Images with Pillow # Pillow is imported as PIL from PIL import ImageTk, Image image1 = Image.open("") test = ImageTk.PhotoImage(image1) label1 = tkinter.Label(image=test) label1.image = test # Position image as the background image label1.place(x=1, y=1) # Resize image to fit on button photoimage = photo.subsample(1, 2) # Position image on button Button(root, image = photoimage,).pack(side = BOTTOM)
