You can create a file named img_viewer.py in your Python editor of choice. You’ll go over it in smaller chunks afterward.
#Eq copy ui layout code#
There will be a lot of code for this example, but don’t worry. Here’s a mock-up of what the image viewer should look like at the end:
#Eq copy ui layout install#
On the other hand, if you install the PySimpleGUIQt port, then you’ll find that Qt supports more image formats out of the box than Tkinter.

Check out the PySimpleGUI demo folder on GitHub for an example that shows how to do this.

If you’d like to be able to open other image file types, then you can download Pillow, which supports TIFF, JPG, and BMP formats. Unfortunately, the Image() element can only display PNG and GIF formats in the regular version of PySimpleGUI. To keep things simple, you’ll use PySimpleGUI’s built-in Image() element for viewing images.

You can use this code to view your own photos or incorporate it to view photos that you download or read from a database. Being able to write your own custom image viewer with Python is fun. One of the demos on PySimpleGUI’s GitHub page is an image viewer. If you want more detail, be sure to check out the other demos that are included with PySimpleGUI. However, there’s a lot more that you can do beyond what can be covered in a single tutorial. In the next few sections, you’ll see a few different ways to use PySimpleGUI. You can create anything from desktop widgets to full-blown user interfaces. The demos that are included with the package are extensive. You can create a large variety of different cross-platform GUIs using PySimpleGUI. Now you’re ready to create an actual application! The code above creates an application that looks like this: To accomplish that, you break out of the loop and close() the window.

If the user presses the OK button or the Exit button, then you want the program to end. When you use PySimpleGUI, you make an event loop by creating an infinite while loop that reads events from the window object.

When they do that, those events are processed by the event loop. For example, the user might need to press a button in your UI or type something with their keyboard. A graphical user interface needs to run inside a loop and wait for the user to do something. The last block of code is the event loop. Then you create the window and pass in your custom layout. In this case, you add a Text() element and a Button() element. PySimpleGUI uses nested Python lists to lay out its elements. If you’d like to learn more about wxPython, then check out How to Build a Python GUI Application With wxPython. For example, wxPython uses Sizers to lay out elements dynamically. Most GUI toolkits allow you to lay out the elements using absolute positioning or by allowing the GUI to lay them out dynamically. read () # End program if user closes window or # presses the OK button if event = "OK" or event = sg. Window ( "Demo", layout ) # Create an event loop while True : event, values = window. # hello_psg.py import PySimpleGUI as sg layout =, ] # Create the window window = sg. PySimpleGUI is still quite powerful and can get most things done with a little work. But don’t let this stop you from giving PySimpleGUI a try.

When you install PySimpleGUI, you get the Tkinter variant by default. PySimpleGUI has wrapped most of PySide2, but only a small portion of wxPython. PySimpleGUI wraps the entirety of Tkinter, which comes with Python. However, each of the ports has to be installed separately.

PySimpleGUI wraps portions of each of these other packages and makes them easier to use. PySimpleGUI was launched in 2018, so it’s a relatively new package compared with the likes of wxPython or PyQt.
