<h1 id="the-pysimplegui-cookbook">The PySimpleGUI Cookbook</h1>
|
||
|
|
<p>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. </p>
|
||
|
|
<p>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: </p>
|
||
|
|
<pre><code>import PySimpleGUI as sg
|
||
|
|
</code></pre>
|
||
|
|
<p>with </p>
|
||
|
|
<pre><code>import PySimpleGUI27 as sg
|
||
|
|
</code></pre>
|
||
|
|
<p>There is a short section in the Readme with instruction on installing PySimpleGUI </p>
|
||
|
|
<p>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. </p>
|
||
|
|
<h1 id="copy-these-design-patterns">Copy these design patterns!</h1>
|
||
|
|
<p>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</p>
|
||
|
|
<p>The one-shot window is one that pops up, collects some data, and then disappears. It is more or less a 'form'.</p>
|
||
|
|
<p>The "Persistent" window is one that sticks around. With these programs, you loop, reading and processing "events" such as button clicks. </p>
|
||
|
|
<h2 id="pattern-1-one-shot-window-read-int-list-the-most-common-pattern">Pattern 1 - "One-shot Window" - Read int list (The Most Common Pattern)</h2>
|
||
|
|
<p>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.</p>
|
||
|
|
<p>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.</p>
|
||
|
|
<pre><code class="python">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]
|
||
|
|
</code></pre>
|
||
|
|
|
||
|
|
<h2 id="pattern-2-a-persistent-window-multiple-reads-using-an-event-loop">Pattern 2 A - Persistent window (multiple reads using an event loop)</h2>
|
||
|
|
<p>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. </p>
|
||
|
|
<p>This code will present a window and will print values until the user clicks the exit button or closes window using an X. </p>
|
||
|
|
<p>Note the <code>do_not_clear</code> parameter that is described in the next design pattern.</p>
|
||
|
|
<pre><code class="python">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()
|
||
|
|
</code></pre>
|
||
|
|
|
||
|
|
<h2 id="pattern-2-b-persistent-window-multiple-reads-using-an-event-loop-updates-data-in-window">Pattern 2 B - Persistent window (multiple reads using an event loop + updates data in window)</h2>
|
||
|
|
<p>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.</p>
|
||
|
|
<p>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.</p>
|
||
|
|
<p>A final note... the parameter <code>do_not_clear</code> 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).</p>

## Animated Matplotlib Graph

<h2 id="tight-layout-with-button-states">Tight Layout with Button States</h2>
|

|
|
<p>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. </p>
|
||
|
|
<p>This Recipe also contains code that implements the button interactions so that you'll have a template to build from. </p>
|
||
|
|
<p>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. </p>

|
<p>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. </p>

<p>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 <br />
|
||
|

. <br />
|

|

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. </p>

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\"

<h2 id="menus">Menus</h2>

<p>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. </p>
|
||
|
|
<p>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. </p>
|
||
|
|
<p>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 <code>tearoff=True</code> in your call to <code>sg.Menu()</code> </p>

<h2 id="creating-a-windows-exe-file">Creating a Windows .EXE File</h2>
|

|

<p>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. </p>
|
||
|
|
<p>Installation of the packages, you'll need to install PySimpleGUI and PyInstaller (you need to install only once) </p>
|
||
|
|
<pre><code>pip install PySimpleGUI
|
||
|
|
pip install PyInstaller
|
||
|
|
</code></pre>
|
||
|
|
<p>To create your EXE file from your program that uses PySimpleGUI, <code>my_program.py</code>, enter this command in your Windows command prompt: </p>
|
||
|
|
<pre><code>pyinstaller -wF my_program.py
|
||
|
|
</code></pre>
|
||
|
|
<p>You will be left with a single file, <code>my_program.exe</code>, located in a folder named <code>dist</code> under the folder where you executed the <code>pyinstaller</code> command. </p>
|
||
|
|
<p>That's all... Run your <code>my_program.exe</code> file on the Windows machine of your choosing. </p>
|
||
|

||
|
|
<p>(famous last words that screw up just about anything being referenced) </p>
|
||
|
|
</blockquote>
|
||
|
|
<p>Your EXE file should run without creating a "shell window". Only the GUI window should show up on your taskbar.</p></div>
