[PyGUI] How to reuse a window layout based on mysql rowcount?

[deanhystad]

You cannot reuse a layout. This is one reason why all PySimpleGUI code has layouts defined inside of functions instead of global variables. Each time you call the function you get a new layout. But your code creates two layouts. Only one window, but two layouts. I removed the database calls and this code makes one window.

import PySimpleGUI as sg

def resultslayout():
    for word in ['Hello', 'World']:
        layout2 = [[sg.Text(word)], [sg.OK()]]
    window = sg.Window('Second Form', layout2)
    event, values = window.read()
    window.close()

resultslayout()

This code makes two windows, but you see them sequentially. The World window appears after you close the Hello window.

import PySimpleGUI as sg

def resultslayout():
    for word in ['Hello', 'World']:
        layout2 = [[sg.Text(word)], [sg.OK()]]
        window = sg.Window('Second Form', layout2)
        event, values = window.read()
        window.close()

resultslayout()

If you want to make two windows that are open at the same time, that is a bit tricky.

import PySimpleGUI as sg

def resultslayout():
    for word in ['Hello', 'World']:
        layout = [[sg.Text(word)], [sg.OK()]]
        sg.Window('Form', layout, finalize=True)

    while True:
        window, event, values = sg.read_all_windows()
        if window == sg.WIN_CLOSED:     # if all windows were closed
            break
        if event == sg.WIN_CLOSED or event == 'OK':
            window.close()

resultslayout()

For multiple windows you could also create windows inside threads
