i'm new with Python & PySimpleGUI and i don't know how to force my application to handle the event key; this is my code:

    # Text field
    sg.InputText(
        key=key,
        default_text='',
        enable_events=True,
    ),


    ...


    window = self.graphic_interface.window

    while self.is_running:
        self.event, self.values = window.read(timeout=0)

    ...


    if event in INSERT_SN_KEYS:
        key = event

        if values[key]is not None:
            # Accept only numbers
            if values[key][-1] not in '0123456789':
                window[key].update(values[key][:-1])

My code can handle any key pressed by user except ; i haven't found any argument for InputText similar to "bind_return_key=True" used into Button class. How can i do it? Thanks

Using method bind("<Return>", key_modifier) of sg.Input after window finalized, it will generate an event sg.Input().Key + key_modifier when this element focused and Enter key pressed.

import PySimpleGUI as sg

sg.theme("DarkBlue3")
sg.set_options(font=("Courier New", 16))

layout = [
    [sg.Input("Enter to generate an event",     key='Input1')],
    [sg.Input("Enter not to generate an event", key='Input2')],
]
window = sg.Window('Title', layout, finalize=True)
window['Input1'].bind("<Return>", "_Enter")

while True:
    event, values = window.read()
    if event == sg.WINDOW_CLOSED:
        break
    elif event == "Input1" + "_Enter":
        print(event)

window.close()
