[PySimpleGUI] New GUI Package. Customize with ease

[PySimpleGUI]

My goal is to put GUIs into the hands of beginners in their first week of coding.

My motto is: first learn the basics. If the beginners then see a code with tkinter, they understand nothing.

Exactly!

Learn the basics about how a GUI can be used and works, then when they can understand more advanced, look at tkinter or some other framework. PySimpleGUI is not a detour from tkinter, it's on the way to tkinter.

Have you looked at PySimpleGUI and tried to make a sample GUI? You're making it sound like it's a lot of work to learn and use. It's a nothing investment for a GUI outcome. Not understanding at all the pushback for using it.

1,000's of people are using EasyGUI. Do you think it's a waste for people to use it too? If there wasn't a need, EasyGUI wouldn't get 100s of installs a day despite it not being maintained for a long time.

It's not just beginners using PySimpleGUI.

The folks making the PyMuPDF are using it for their utilities. One of the engineers sent me this PDF reader today. A few lines of code and you're able to preview a PDF file. Not all developers are super-strict, no outside of core-packages until the basics are all down. Some just want to get the job done. A basic GUI that's running is a lot better than a tkinter GUI that is given up on.

def get_page(pno):
    pix = doc[pno].getPixmap(alpha = False)
    return pix.getPNGData()

form = sg.FlexForm(title)

data = get_page(0)

             sg.Quit()]  ]

    button,value = form.Read()
    if button in (None, 'Quit'):
        break
    i -= 1 * button == 'Prev'
    i += 1* button == 'Next'
    i = 0 if button =='First' else -1 if button == 'Last' else i

    except:

    image_elem.Update(data=data)
