The PySimpleGUI Cookbook
You'll find that starting with a Recipe will give you a big jump-start on creating your custom GUI. Copy and paste one of these Recipes and modify it to match your requirements. Study them to get an idea of what design patterns to follow.
The Recipes in this Cookbook all assume you're running on a Python3 machine. If you are running Python 2.7 then your code will differ by 2 character. Replace the import statement:
import PySimpleGUI as sg
with
import PySimpleGUI27 as sg
There is a short section in the Readme with instruction on installing PySimpleGUI
If you like this Cookbook, then you'll LOVE the 100+ sample programs that are just like these. You'll find them in the GitHub at http://www.PySimpleGUI.com. These Recipes are simply several of those programs displayed in document format.
Experimental repl.it Embedded Windows
You'll find a few of these Recipes are running in your browser window using PySimpleGUIWeb. They are included so that you can immediately play around with the SDK before installing one of the PySimpleGUI variants on your computer.
This is a new capability for PySimpleGUI that has only very recently been started. Only a few of the elements are operational using PySimpleGUIWeb. So, be prepared for some bugs. It's got a ways to go, but still seemed valuable to include.
Copy these design patterns!
All of your PySimpleGUI programs will utilize one of these 2 design patterns depending on the type of window you're implementing. The two types of windows are:
- One-shot window
- Persistent window
The one-shot window is one that pops up, collects some data, and then disappears. It is more or less a 'form'.
The "Persistent" window is one that sticks around. With these programs, you loop, reading and processing "events" such as button clicks.
Pattern 1 - "One-shot Window" - Read int list (The Most Common Pattern)
This will be the most common pattern you'll follow if you are not using an "event loop" (not reading the window multiple times). The window is read and then closes.
Because no "keys" were specified in the window layout, the return values will be a list of values. If a key is present, then the values are a dictionary. See the main readme document or further down in this document for more on these 2 ways of reading window values.
import PySimpleGUI as sg
layout = [[sg.Text('My one-shot window.')],
[sg.InputText()],
[sg.Submit(), sg.Cancel()]]
window = sg.Window('Window Title').Layout(layout)
event, values = window.Read()
window.Close()
text_input = values[0]
print(text_input)
Pattern 2 A - Persistent window (multiple reads using an event loop)
Some of the more advanced programs operate with the window remaining visible on the screen. Input values are collected, but rather than closing the window, it is kept visible acting as a way to both output information to the user and gather input data.
This code will present a window and will print values until the user clicks the exit button or closes window using an X.
Note the do_not_clear parameter that is described in the next design pattern.
import PySimpleGUI as sg
layout = [[sg.Text('Persistent window')],
[sg.Input(do_not_clear=True)],
[sg.Button('Read'), sg.Exit()]]
window = sg.Window('Window that stays open').Layout(layout)
while True:
event, values = window.Read()
if event is None or event == 'Exit':
break
print(event, values)
window.Close()
Pattern 2 B - Persistent window (multiple reads using an event loop + updates data in window)
This is a slightly more complex, but maybe more realistic version that reads input from the user and displays that input as text in the window. Your program is likely to be doing both of those activities so this will give you a big jump-start.
Do not worry yet what all of these statements mean. Just copy it so you can begin to play with it, make some changes. Experiment to see how thing work.
A final note... the parameter do_not_clear in the input call determines the action of the input field after a button event. If this value is True, the input value remains visible following button clicks. If False, then the input field is CLEARED of whatever was input. If you are building a "Form" type of window with data entry, you likely want False, the default setting (you can remove the parameter completely).
import sys
if sys.version_info[0] >= 3:
import PySimpleGUI as sg
else:
import PySimpleGUI27 as sg
layout = [[sg.Text('Your typed chars appear here:'), sg.Text('', key='_OUTPUT_') ],
[sg.Input(do_not_clear=True, key='_IN_')],

Simple Data Entry - Return Values As List
Same GUI screen except the return values are in a list instead of a dictionary and doesn't have initial values.
import PySimpleGUI as sg
# Very basic window. Return values as a list
layout = [
[sg.Text('Please enter your Name, Address, Phone')],
[sg.Text('Name', size=(15, 1)), sg.InputText()],
[sg.Text('Address', size=(15, 1)), sg.InputText()],
[sg.Text('Phone', size=(15, 1)), sg.InputText()],
[sg.Submit(), sg.Cancel()]
]
window = sg.Window('Simple data entry window').Layout(layout)
event, values = window.Read()
window.Close()
print(event, values[0], values[1], values[2])
Simple data entry - Return Values As Dictionary
A simple GUI with default values. Results returned in a dictionary.
import PySimpleGUI as sg
# Very basic window. Return values as a dictionary
layout = [
[sg.Text('Please enter your Name, Address, Phone')],
[sg.Text('Name', size=(15, 1)), sg.InputText('name', key='_NAME_')],
[sg.Text('Address', size=(15, 1)), sg.InputText('address', key='_ADDRESS_')],
[sg.Text('Phone', size=(15, 1)), sg.InputText('phone', key='_PHONE_')],
[sg.Submit(), sg.Cancel()]
]
window = sg.Window('Simple data entry GUI').Layout(layout)
event, values = window.Read()
window.Close()
print(event, values['_NAME_'], values['_ADDRESS_'], values['_PHONE_'])
Simple File Browse
Browse for a filename that is populated directly into the user's variable
import PySimpleGUI as sg
layout = [[sg.Text('SHA-1 and SHA-256 Hashes for the file')],
[sg.InputText(), sg.FileBrowse()],
[sg.Submit(), sg.Cancel()]]
(event, (source_filename,)) = sg.Window('SHA-1 & 256 Hash').Layout(layout ).Read()
print(event, source_filename)
Add GUI to Front-End of Script
Quickly add a GUI allowing the user to browse for a filename if a filename is not supplied on the command line using this 1-line GUI. It's the best of both worlds.
import PySimpleGUI as sg
import sys
if len(sys.argv) == 1:
event, (fname,) = sg.Window('My Script').Layout([[sg.Text('Document to open')],
[sg.In(), sg.FileBrowse()],
[sg.CloseButton('Open'), sg.CloseButton('Cancel')]]).Read()
else:
fname = sys.argv[1]
if not fname:
sg.Popup("Cancel", "No filename supplied")
raise SystemExit("Cancelling: no filename supplied")
print(event, fname)
Compare 2 Files
Browse to get 2 file names that can be then compared.
import PySimpleGUI as sg
layout = [[sg.Text('Enter 2 files to comare')],
[sg.Text('File 1', size=(8, 1)), sg.InputText(), sg.FileBrowse()],
[sg.Text('File 2', size=(8, 1)), sg.InputText(), sg.FileBrowse()],
[sg.Submit(), sg.Cancel()]]
window = sg.Window('File Compare').Layout(layout)
event, values = window.Read()
window.Close()
print(event, values)
Nearly All Widgets with Green Color Theme
Example of nearly all of the widgets in a single window. Uses a customized color scheme.

event, values = window.Read()
sg.Popup('Title',
'The results of the window.',
'The button clicked was "{}"'.format(event),
'The values are', values)
Non-Blocking Window With Periodic Update
An async Window that has a event read loop. A Text Element is updated periodically with a running timer. Note that value is checked for None which indicates the window was closed using X.
Use caution when using windows with a timeout. You should rarely need to use a timeout=0, non-blocking call, so try not to abuse this design pattern.
import PySimpleGUI as sg
layout = [[sg.Text('Stopwatch', size=(20, 2), justification='center')],
[sg.Text('', size=(10, 2), font=('Helvetica', 20), justification='center', key='_OUTPUT_')],
[sg.T(' ' * 5), sg.Button('Start/Stop', focus=True), sg.Quit()]]
window = sg.Window('Running Timer').Layout(layout)
timer_running = True
i = 0
# Event Loop
while True:
i += 1 * (timer_running is True)
event, values = window.Read(timeout=10) # Please try and use a timeout when possible
if event is None or event == 'Quit': # if user closed the window using X or clicked Quit button
break
elif event == 'Start/Stop':
timer_running = not timer_running
window.FindElement('_OUTPUT_').Update('{:02d}:{:02d}.{:02d}'.format((i // 100) // 60, (i // 100) % 60, i % 100))
Callback Function Simulation
The architecture of some programs works better with button callbacks instead of handling in-line. While button callbacks are part of the PySimpleGUI implementation, they are not directly exposed to the caller. The way to get the same result as callbacks is to simulate them with a recipe like this one.
import PySimpleGUI as sg
# This design pattern simulates button callbacks
# Note that callbacks are NOT a part of the package's interface to the
# caller intentionally. The underlying implementation actually does use
# tkinter callbacks. They are simply hidden from the user.
# The callback functions
def button1():
print('Button 1 callback')
def button2():
print('Button 2 callback')
# Layout the design of the GUI
layout = [[sg.Text('Please click a button', auto_size_text=True)],
[sg.Button('1'), sg.Button('2'), sg.Quit()]]
# Show the Window to the user
window = sg.Window('Button callback example').Layout(layout)
# Event loop. Read buttons, make callbacks
while True:
# Read the Window
event, value = window.Read()
# Take appropriate action based on button
if event == '1':
button1()
elif event == '2':
button2()
elif event =='Quit' or event is None:
window.Close()
break
# All done!
sg.PopupOK('Done')
Realtime Buttons (Good For Raspberry Pi)
This recipe implements a remote control interface for a robot. There are 4 directions, forward, reverse, left, right. When a button is clicked, PySimpleGUI immediately returns button events for as long as the buttons is held down. When released, the button events stop. This is an async/non-blocking window.
import PySimpleGUI as sg
layout = [[sg.Text('Robotics Remote Control')],
[sg.T(' ' * 10), sg.RealtimeButton('Forward')],
[sg.RealtimeButton('Left'), sg.T(' ' * 15), sg.RealtimeButton('Right')],
[sg.T(' ' * 10), sg.RealtimeButton('Reverse')],
[sg.T('')],
[sg.Quit(button_color=('black', 'orange'))]
]
window = sg.Window('Robotics Remote Control', auto_size_text=True).Layout(layout )
#
# Some place later in your code...
# You need to perform a Read or Refresh on your window every now and then or
# else it will appear your program has hung
#
# your program's main loop
while (True):
# This is the code that reads and updates your window
event, values = window.Read(timeout=10)
if event is not None:
print(event)
if event == 'Quit' or values is None:
break
window.Close() # Don't forget to close your window!
OneLineProgressMeter
This recipe shows just how easy it is to add a progress meter to your code.
import PySimpleGUI as sg
for i in range(1000):
sg.OneLineProgressMeter('One Line Meter Example', i+1, 1000, 'key')
Button Graphics (Media Player)
Buttons can have PNG of GIF images on them. This Media Player recipe requires 4 images in order to function correctly. The background is set to the same color as the button background so that they blend together.

Script Launcher - Persistent Window
This Window doesn't close after button clicks. To achieve this the buttons are specified as sg.Button instead of sg.Button. The exception to this is the EXIT button. Clicking it will close the window. This program will run commands and display the output in the scrollable window.

Custom Progress Meter / Progress Bar
Perhaps you don't want all the statistics that the EasyProgressMeter provides and want to create your own progress bar. Use this recipe to do just that.
import PySimpleGUI as sg
# layout the Window
layout = [[sg.Text('A custom progress meter')],
[sg.ProgressBar(1000, orientation='h', size=(20, 20), key='progbar')],
[sg.Cancel()]]
# create the Window
window = sg.Window('Custom Progress Meter').Layout(layout)
# loop that would normally do something useful
for i in range(1000):
# check to see if the cancel button was clicked and exit loop if clicked
event, values = window.Read(timeout=0)
if event == 'Cancel' or event is None:
break
# update bar with loop value +1 so that bar eventually reaches the maximum
window.FindElement('progbar').UpdateBar(i + 1)
# done with loop... need to destroy the window as it's still open
window.Close()
The One-Line GUI
For those of you into super-compact code, a complete customized GUI can be specified, shown, and received the results using a single line of Python code.
Instead of
import PySimpleGUI as sg
layout = [[sg.Text('Filename')],
[sg.Input(), sg.FileBrowse()],
[sg.OK(), sg.Cancel()]]
event, (number,) = sg.Window('Get filename example').Layout(layout).Read()
you can write this line of code for the exact same result (OK, two lines with the import):
import PySimpleGUI as sg
event, (filename,) = sg.Window('Get filename example').Layout(
[[sg.Text('Filename')], [sg.Input(), sg.FileBrowse()], [sg.OK(), sg.Cancel()]]).Read()
Multiple Columns
A Column is required when you have a tall element to the left of smaller elements.
In this example, there is a Listbox on the left that is 3 rows high. To the right of it are 3 single rows of text and input. These 3 rows are in a Column Element.
To make it easier to see the Column in the window, the Column background has been shaded blue. The code is wordier than normal due to the blue shading. Each element in the column needs to have the color set to match blue background.
import PySimpleGUI as sg
# Demo of how columns work
# GUI has on row 1 a vertical slider followed by a COLUMN with 7 rows
# Prior to the Column element, this layout was not possible
# Columns layouts look identical to GUI layouts, they are a list of lists of elements.
sg.ChangeLookAndFeel('BlueMono')
# Column layout
col = [[sg.Text('col Row 1', text_color='white', background_color='blue')],
[sg.Text('col Row 2', text_color='white', background_color='blue'), sg.Input('col input 1')],
[sg.Text('col Row 3', text_color='white', background_color='blue'), sg.Input('col input 2')]]
layout = [[sg.Listbox(values=('Listbox Item 1', 'Listbox Item 2', 'Listbox Item 3'), select_mode=sg.LISTBOX_SELECT_MODE_MULTIPLE, size=(20,3)), sg.Column(col, background_color='blue')],
[sg.Input('Last input')],
[sg.OK()]]
# Display the Window and get values
event, values = sg.Window('Compact 1-line Window with column').Layout(layout).Read()
sg.Popup(event, values, line_width=200)
Persistent Window With Text Element Updates
This simple program keep a window open, taking input values until the user terminates the program using the "X" button.
import PySimpleGUI as sg
layout = [ [sg.Txt('Enter values to calculate')],
[sg.In(size=(8,1), key='numerator')],
[sg.Txt('_' * 10)],
[sg.In(size=(8,1), key='denominator')],
[sg.Txt('', size=(8,1), key='output') ],
[sg.Button('Calculate', bind_return_key=True)]]
window = sg.Window('Math').Layout(layout)
while True:
event, values = window.Read()
if event is not None:
try:
numerator = float(values['numerator'])
denominator = float(values['denominator'])
calc = numerator / denominator
except:
calc = 'Invalid'
window.FindElement('output').Update(calc)
else:
break
One Element Updating Another - Compound Elements
You can easily build "compound elements" in a single like of code. This recipe shows you how to add a numeric value onto a slider.
import PySimpleGUI as sg
layout = [[sg.Text('Slider Demonstration'), sg.Text('', key='_OUTPUT_')],
[sg.T('0',key='_LEFT_'),
sg.Slider((1,100), key='_SLIDER_', orientation='h', enable_events=True, disable_number_display=True),
sg.T('0', key='_RIGHT_')],
[sg.Button('Show'), sg.Button('Exit')]]
window = sg.Window('Window Title').Layout(layout)
while True: # Event Loop
event, values = window.Read()
print(event, values)
if event is None or event == 'Exit':
break
window.Element('_LEFT_').Update(values['_SLIDER_'])
window.Element('_RIGHT_').Update(values['_SLIDER_'])

This recipe is a design pattern for multiple windows where the first window is not active while the second window is showing. The first window is hidden to discourage continued interaction.

tkinter Canvas Widget
The Canvas Element is one of the few tkinter objects that are directly accessible. The tkinter Canvas widget itself can be retrieved from a Canvas Element like this:
can = sg.Canvas(size=(100,100))
tkcanvas = can.TKCanvas
tkcanvas.create_oval(50, 50, 100, 100)
While it's fun to scribble on a Canvas Widget, try Graph Element makes it a downright pleasant experience. You do not have to worry about the tkinter coordinate system and can instead work in your own coordinate system.
import PySimpleGUI as sg
layout = [
[sg.Canvas(size=(100, 100), background_color='red', key= 'canvas')],
[sg.T('Change circle color to:'), sg.Button('Red'), sg.Button('Blue')]
]
window = sg.Window('Canvas test')
window.Layout(layout)
window.Finalize()
canvas = window.FindElement('canvas')
cir = canvas.TKCanvas.create_oval(50, 50, 100, 100)
while True:
event, values = window.Read()
if event is None:
break
if event == 'Blue':
canvas.TKCanvas.itemconfig(cir, fill="Blue")
elif event == 'Red':
canvas.TKCanvas.itemconfig(cir, fill="Red")
Graph Element - drawing circle, rectangle, etc, objects
Just like you can draw on a tkinter widget, you can also draw on a Graph Element. Graph Elements are easier on the programmer as you get to work in your own coordinate system.
import PySimpleGUI as sg
layout = [
[sg.Graph(canvas_size=(400, 400), graph_bottom_left=(0,0), graph_top_right=(400, 400), background_color='red', key='graph')],
[sg.T('Change circle color to:'), sg.Button('Red'), sg.Button('Blue'), sg.Button('Move')]
]
window = sg.Window('Graph test')
window.Layout(layout)
window.Finalize()
graph = window.FindElement('graph')
circle = graph.DrawCircle((75,75), 25, fill_color='black',line_color='white')
point = graph.DrawPoint((75,75), 10, color='green')
oval = graph.DrawOval((25,300), (100,280), fill_color='purple', line_color='purple' )
rectangle = graph.DrawRectangle((25,300), (100,280), line_color='purple' )
line = graph.DrawLine((0,0), (100,100))
while True:
event, values = window.Read()
if event is None:
break
if event is 'Blue':
graph.TKCanvas.itemconfig(circle, fill = "Blue")
elif event is 'Red':
graph.TKCanvas.itemconfig(circle, fill = "Red")
elif event is 'Move':
graph.MoveFigure(point, 10,10)
graph.MoveFigure(circle, 10,10)
graph.MoveFigure(oval, 10,10)
graph.MoveFigure(rectangle, 10,10)
Keypad Touchscreen Entry - Input Element Update
This Recipe implements a Raspberry Pi touchscreen based keypad entry. As the digits are entered using the buttons, the Input Element above it is updated with the input digits.

- Update of Elements in window (Input, Text)
- do_not_clear of Input Elements

Animated Matplotlib Graph
Use the Canvas Element to create an animated graph. The code is a bit tricky to follow, but if you know Matplotlib then this recipe shouldn't be too difficult to copy and modify.

tkagg.blit(photo, figure_canvas_agg.get_renderer()._renderer, colormode=2)
Tight Layout with Button States
Saw this example layout written in tkinter and liked it so much I duplicated the interface. It's "tight", clean, and has a nice dark look and feel.
This Recipe also contains code that implements the button interactions so that you'll have a template to build from.
In other GUI frameworks this program would be most likely "event driven" with callback functions being used to communicate button events. The "event loop" would be handled by the GUI engine. If code already existed that used a call-back mechanism, the loop in the example code below could simply call these callback functions directly based on the button text it receives in the window.Read call.
import PySimpleGUI as sg

Desktop Floating Toolbar
Hiding your windows commmand window
For this and the Time & CPU Widgets you may wish to consider using a tool or technique that will hide your Windows Command Prompt window. I recommend the techniques found on this site:
http://www.robvanderwoude.com/battech_hideconsole.php
At the moment I'm using the technique that involves wscript and a script named RunNHide.vbs. They are working beautifully. I'm using a hotkey program and launch by using this script with the command "python.exe insert_program_here.py". I guess the next widget should be one that shows all the programs launched this way so you can kill any bad ones. If you don't properly catch the exit button on your window then your while loop is going to keep on working while your window is no longer there so be careful in your code to always have exit explicitly handled.
Floating toolbar
This is a cool one! (Sorry about the code pastes... I'm working in it)
Impress your friends at what a tool-wizard you are by popping a custom toolbar that you keep in the corner of your screen. It stays on top of all your other windows.
You can easily change colors to match your background by changing a couple of parameters in the code.

Timer Desktop Widget Creates a floating timer that is always on top of other windows You move it by grabbing anywhere on the window Good example of how to do a non-blocking, polling program using SimpleGUI Can be used to poll hardware when running on a Pi
While the timer ticks are being generated by PySimpleGUI's "timeout" mechanism, the actual value
of the timer that is displayed comes from the system timer, time.time(). This guarantees an
accurate time value is displayed regardless of the accuracy of the PySimpleGUI timer tick. If
this design were not used, then the time value displayed would slowly drift by the amount of time
it takes to execute the PySimpleGUI read and update calls (not good!)
NOTE - you will get a warning message printed when you exit using exit button.

Menus
Menus are nothing more than buttons that live in a menu-bar. When you click on a menu item, you get back a "button" with that menu item's text, just as you would had that text been on a button.
Menu's are defined separately from the GUI window. To add one to your window, simply insert sg.Menu(menu_layout). The menu definition is a list of menu choices and submenus. They are a list of lists. Copy the Recipe and play with it. You'll eventually get when you're looking for.
If you double click the dashed line at the top of the list of choices, that menu will tear off and become a floating toolbar. How cool! To enable this feature, set the parameter tearoff=True in your call to sg.Menu()

Graphing with Graph Element
Use the Graph Element to draw points, lines, circles, rectangles using your coordinate systems rather than the underlying graphics coordinates.
In this example we're defining our graph to be from -100, -100 to +100,+100. That means that zero is in the middle of the drawing. You define this graph description in your call to Graph.
import math

Creating a Windows .EXE File
It's possible to create a single .EXE file that can be distributed to Windows users. There is no requirement to install the Python interpreter on the PC you wish to run it on. Everything it needs is in the one EXE file, assuming you're running a somewhat up to date version of Windows.
Installation of the packages, you'll need to install PySimpleGUI and PyInstaller (you need to install only once)
pip install PySimpleGUI
pip install PyInstaller
To create your EXE file from your program that uses PySimpleGUI, my_program.py, enter this command in your Windows command prompt:
pyinstaller -wF my_program.py
You will be left with a single file, my_program.exe, located in a folder named dist under the folder where you executed the pyinstaller command.
That's all... Run your my_program.exe file on the Windows machine of your choosing.
"It's just that easy."
(famous last words that screw up just about anything being referenced)
Your EXE file should run without creating a "shell window". Only the GUI window should show up on your taskbar.
