Popup window

Create a simple pop-up window interface. The default library abbreveation is sg, and it is recommended to use this name when using it.

import PySimpleGUI as sg
sg.popup("Hello World")

There are many popup types, a demo is shown below.

sg.popup('Attention!')
sg.popup_ok('Default popup')
sg.popup_yes_no('Popup with Yes and No buttons')
sg.popup_cancel('Popup with cancel button')
sg.popup_ok_cancel('Popup with OK and cancel buttons')
sg.popup_error('popup with red error button')
sg.popup_auto_close('Popup window that closes automatically after a few seconds')

You can set custom parameters. For example, setting up a small customized window:

sg.popup(
    'window',
    title='Hello',
    button_color=('#A81B0C', '#FFFFFF'),
    background_color='#F47264',
    line_width=2,
    custom_text='text'
)

Text content popup window

Use the popup_scrolled() method, and add the content to be displayed in parentheses

text = "Hello"
sg.popup_scrolled(text,title='Hello')

Get user input

Using the PySimpleGUI popup_get_text() method, you can get user input. It is somewhat similar to the prompt in the input() statement, reminding the user to enter text.

text1 = sg.popup_get_text('Enter text1: ')
print(text1)
text2 = sg.popup_get_text('Enter text2: ')
print(text2)

Test for hidden password input, you can get the user input password in the form of a pop-up window:

text = sg.popup_get_text('Enter password', password_char='*')
sg.popup(f'Password:{text}')

File selection popup window

Use the sg.popup_get_file() method to select a file.

path = sg.popup_get_file('Select a file')
print(path)

You can add paramters:

• message
• default_path
• save_as (bool)
• multiple_files (bool)
• file_types
• initial_folder

Select directory window

The sg.popup_get_folder() method is used as an input prompt to select a folder. After executing the program, a window for selecting files will pop up, and the path of the folder will be added to the input box after selection.

path = sg.popup_get_folder('Select folder')
print(path)

Progress bar pop-up window

Use the sg.one_line_progress_meter() method, and enter the relevant parameter settings in parentheses.

for i in range(1000):
    sg.one_line_progress_meter(
        'progress_bar',
        i + 1,
        1000,
        'this progress bar key',
        'this is a progress bar'
    )

You can change the orientation and colors

for i in range(1, 1000):
    sg.one_line_progress_meter(
        'progress_bar',
        i + 1,
        1000,
        'this progress bar key',
        'this is a progress bar',
        orientation='h',
        bar_color=('#F47264', '#FFFFFF')
    )
