There's a new GUI on the scene!

You'll find PySimpleGUI on PyPI:
pip install --upgrade PySimpleGUI

The GitHub is
https://github.com/MikeTheWatchGuy/PySimpleGUI

It runs on Python3, on the PC, Linux, Mac Raspberry Pi, etc.

It's built on tkinter and has no other dependencies.



A simple GUI can be built, shown, and have the results directly populated into the caller's variables



That GUI requires this much code:
import PySimpleGUI as sg

form = sg.FlexForm('Rename file or folders', location=(800,800)) # begin with a blank form

layout = [[sg.Text('Rename files or folders')],
[sg.Text('Source for Folders', size=(15, 1)), sg.InputText(), sg.FolderBrowse()],
[sg.Text('Source for Files ', size=(15, 1)), sg.InputText(), sg.FolderBrowse()],
[sg.Submit(), sg.Cancel()]]

button, (folder_path, file_path) = form.LayoutAndRead(layout)


I think this is by far the most Python-like GUI that's currently available.

This may sound pretentious, but is there a formal process for submitting proposals for official new packages to the Python Foundation? I think Python is long overdue something like this.

My source code may not be the prettiest. It's the SDK's interface that I focused on.

If you're in need of a GUI and don't have much time, this is a great option. You can code up a custom GUI in under 10 minutes.

Sorry, got the source code a little wrong and didn't format correctly.

import PySimpleGUI as sg

form = sg.FlexForm('Rename file or folders')  # begin with a blank form

layout = [[sg.Text('Rename files or folders')],
          [sg.Text('Source for Folders', size=(15, 1)), sg.InputText(), sg.FolderBrowse()],
          [sg.Text('Source for Files ', size=(15, 1)), sg.InputText(), sg.FolderBrowse()],
          [sg.Submit(), sg.Cancel()]]

button, (folder_path, file_path) = form.LayoutAndRead(layout)

Not to minimize your work, which looks good.
Since it's a wrapper around tkinter, you should give credit to Fredrik Lundh.

It's versatile enough to act as a Machine Learning front-end, or a robotic control GUI on a Raspberry Pi.





It works in synchronous or asynchronous modes.

I will by all means do just that!

Does that belong in the Readme?

Thanks for the suggestion. Anything to make it better is appreciated.

OK, acknowledgement done. Added Fredrik to the readme and posted to GitHub.

It should be the other way around. Button gray and hover blue.

That's no problem. It's a single line of code to configure the defaults. If you want to change button default to that, then call:

sg.SetOptions(button_color=('blue', '#d0d0d0'))

You call it once and it retains the values for all the forms you create.

However, you're right too. The system default colors should be different than the blue buttons. I'll make a change so that the system default is a possible setting instead of forcing a button color.

Demo_DuplicateFileFinder.py gives an error on my Mint18(Ubuntu 16.04) on

    msg = f'{total} Files processed\n'\
          f'{dup_count} Duplicates found\n'

Quote: msg = f'{total} Files processed\n'\
^
SyntaxError: invalid syntax

this works for me

    msg = "%s%s%s%s" % (total , ' Files processed\n', dup_count, ' Duplicates found\n')

DOH!

Sorry about the f-string! Thought I removed all of them.

Thank you so much for pointing it out.

And GREAT to see the post of source code!!

Can Anyone help ?

How can I get the values from s slider when a slider is moved,
How can I get the values once an item is selected from a ComboBox ?

I would like to write a GUI to create the necessary code for PySimpleGUI !

If you are using the latest PySimpleGUI from github, you'll want to download the version I just now uploaded. I broke sliders evidently yesterday.

The return values are either a dictionary or a list depending on how you specified you Elements in your layout. If you used a "key" keyword on any element, then your results will be in dictionary form.

This form has a combobox and a slider:

import PySimpleGUI as sg

with sg.FlexForm('Combo & Slider Demo') as form:
    layout = [
            [sg.Text('Example of a slider and Combobox',font=("Helvetica", 15), text_color='blue')],
            [sg.InputCombo(['Combobox 1', 'Combobox 2'], size=(20, 3))],
            [sg.Slider(range=(1, 100), orientation='h', size=(35, 20), default_value=85)],
            [sg.OK()]
             ]

    button, values = form.LayoutAndRead(layout)

print(values)

This is what the print statement printed:

Output:
['Combobox 1', 85]

I could have written:

button, (combo, slider) = form.LayoutAndRead(layout)

this will populate the variables combo and slider with the values from those 2 fields.

This is why there are branches. So users of given software will always have a stable version to use, and can always use the dev branch if they want the latest features, but with possible bugs.

Currently you only have the master branch. Anytime you upload, you might be potentially breaking it involuntarily without even knowing.
