What is the enable_events on buttons in pysimpleGUI

I wonder what does the parameter enable_events, do for a button (sg.Button).

Indeed, when there is a button in a code, it is always sending an event in the .read(). You don't need to specify enable_events=True AND even if you specify enable_events=False then button still sends an event.

Furthermore, in the reference of PysimpleGUI it is written that the default value of enable_events is False. Do anyone knows what is this about ?

Thank you

Solution

  • sg.Button

    enable_events

    Turns on the element specific events. If this button is a target, should it generate an event when filled in

    Example Code

    import PySimpleGUI as sg

layout = [
    [sg.Input(key='-IN-'), sg.FileBrowse(target="Submit")],
    [sg.Button("Submit", enable_events=True)],
]
window = sg.Window("Title", layout)

while True:

    event, values = window.read()

    if event == sg.WIN_CLOSED:
        break

    print(event, values)

window.close()

    Note: Most of time, we don't need to use this options enable_events=True.
