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.

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: 1. One-shot window 2. 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.FileBrowse()],      
                 [sg.Submit(), sg.Cancel()]]      

window = sg.Window('Window Title').Layout(layout)    

event, values = window.Read()    
window.Close()

source_filename = values[0]    

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_')],  
          [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  
  if event == 'Show':  
      # change the "output" element to be the value of "input" element  
      window.FindElement('_OUTPUT_').Update(values['_IN_'])

window.Close()

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.

super simple 2

    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.

super simple 2

    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

simple file browse

    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.

script front-end

    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.

compare 2 files

    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)

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.

non-blocking

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.

button callback 2

    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'))]      
                 ]

    # else it will appear your program has hung      
    #

    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.

custom progress meter

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.

simple

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.

cookbook columns

    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.

math game

```python
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


## 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:      
```python      
    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.

canvas

```python
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.      

![graph recipe](https://user-images.githubusercontent.com/13696193/45920640-751bb000-be75-11e8-9530-45b71cbae07d.jpg)      

```python

    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)

## 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.      

![animated matplotlib](https://user-images.githubusercontent.com/13696193/44640937-91b9ea80-a992-11e8-9c1c-85ae74013679.jpg)      


```python
from tkinter import *
from random import randint
import PySimpleGUI as sg
from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg, FigureCanvasAgg
from matplotlib.figure import Figure
import matplotlib.backends.tkagg as tkagg
import tkinter as Tk

fig = Figure()

ax = fig.add_subplot(111)
ax.set_xlabel("X axis")
ax.set_ylabel("Y axis")
ax.grid()

layout = [[sg.Text('Animated Matplotlib', size=(40, 1), justification='center', font='Helvetica 20')],
          [sg.Canvas(size=(640, 480), key='canvas')],
          [sg.Button('Exit', size=(10, 2), pad=((280, 0), 3), font='Helvetica 14')]]

# create the window and show it without the plot    


window = sg.Window('Demo Application - Embedding Matplotlib In PySimpleGUI').Layout(layout)
window.Finalize()  # needed to access the canvas element prior to reading the window

canvas_elem = window.FindElement('canvas')

graph = FigureCanvasTkAgg(fig, master=canvas_elem.TKCanvas)
canvas = canvas_elem.TKCanvas

dpts = [randint(0, 10) for x in range(10000)]
# Our event loop      
for i in range(len(dpts)):
    event, values = window.Read(timeout=20)
    if event == 'Exit' or event is None:
        exit(69)

    ax.cla()
    ax.grid()

    ax.plot(range(20), dpts[i:i + 20], color='purple')
    graph.draw()
    figure_x, figure_y, figure_w, figure_h = fig.bbox.bounds
    figure_w, figure_h = int(figure_w), int(figure_h)
    photo = Tk.PhotoImage(master=canvas, width=figure_w, height=figure_h)

    canvas.create_image(640 / 2, 480 / 2, image=photo)

    figure_canvas_agg = FigureCanvasAgg(fig)
    figure_canvas_agg.draw()

    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.

Use the upper half to generate your hash code. Then paste it into the code in the lower half. Copy and paste lower 1/2 into your code to get password protection for your script without putting the password into your source code.

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.

toolbar gray

You can easily change colors to match your background by changing a couple of parameters in the code.

Desktop Floating Widget - Timer

This is a little widget you can leave running on your desktop. Will hopefully see more of these for things like checking email, checking server pings, displaying system information, dashboards, etc
.
Much of the code is handling the button states in a fancy way. It could be much simpler if you don't change the button text based on state.

"""
 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.
 It will look something like: invalid command name \"1616802625480StopMove\"

Desktop Floating Widget - CPU Utilization

Like the Timer widget above, this script can be kept running. You will need the package psutil installed in order to run this Recipe.

The spinner changes the number of seconds between reads. Note that you will get an error message printed when exiting because the window does not have have a titlebar. It's a known problem.

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.

graph markers

import math    
import PySimpleGUI as sg    

layout = [[sg.Graph(canvas_size=(400, 400), graph_bottom_left=(-105,-105), graph_top_right=(105,105), background_color='white', key='graph', tooltip='This is a cool graph!')],]    

window = sg.Window('Graph of Sine Function', grab_anywhere=True).Layout(layout).Finalize()    
graph = window.FindElement('graph')    

# Draw axis

graph.DrawLine((0,-100), (0,100))    

for x in range(-100, 101, 20):    
    graph.DrawLine((x,-3), (x,3))

        graph.DrawText( x, (x,-10), color='green')

        graph.DrawText( y, (-10,y), color='blue')    

# Draw Graph    
for x in range(-100,100):    
    y = math.sin(x/20)*50    
    graph.DrawCircle((x,y), 1, line_color='red', fill_color='red')    

event, values = window.Read()  

Tabs

Tabs bring not only an extra level of sophistication to your window layout, they give you extra room to add more elements. Tabs are one of the 3 container Elements, Elements that hold or contain other Elements. The other two are the Column and Frame Elements.

tabs

import PySimpleGUI as sg    

tab1_layout =  [[sg.T('This is inside tab 1')]]

          [sg.Button('Read')]]    

window = sg.Window('My window with tabs', default_element_size=(12,1)).Layout(layout)    

while True:    
    event, values = window.Read()    
    print(event,values)    
    if event is None:           # always,  always give a way out!    
        break  

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.
