• Searched main docs for your problem PySimpleGUI Documenation
• Looked for Demo Programs that are similar to your goal. It is recommend you use the Demo Browser! Demo Programs
• None of your GUI code was generated by an AI algorithm like GPT
• If not tkinter - looked for Demo Programs for specific port
• For non tkinter - Looked at readme for your specific port if not PySimpleGUI (Qt, WX, Remi)
• Run your program outside of your debugger (from a command line)
• Searched through Issues (open and closed) to see if already reported Issues.PySimpleGUI.com
• Have upgraded to the latest release of PySimpleGUI on PyPI (lastest official version)
• Tried running the Development Build. Your problem may have already been fixed but not released. Check Home Window for release notes and upgrading capability

Detailed Description

First Question:
All Fields are mandatory on my 3 Field screen. Using a mouse click, it is possible to bypass the AGE Field. Then SUBMIT is pressed.

I would then check to see that none of the Fields are NULL (empty). If I determine that the AGE Field (or any Field) is NULL, how do I go back and ask for it to be re-entered ?

Second Question:
If a Field is entered followed by a Carriage Return - is there any way to make it act like the TAB key and go on to the next Field ?

Thanks,
M....

Code To Duplicate

import PySimpleGUI as sg

layout = [
    [sg.Text('Name: ',tooltip='Name 3-31 Char'),sg.Input(default_text ="",enable_events=True,key='-NAME-')],
    [sg.Text('Age:    ', tooltip='Age 16-99'), sg.Input(default_text="",enable_events=True,key='-AGE-')],
    [sg.Text('Date:   ', tooltip='Date YYMMDD'), sg.Input(default_text="",enable_events=True,key='-DATE-')],
    [sg.Button("Update"), sg.Button("Exit")],
	]
winx = sg.Window('Customer Data Entry', layout)

while True:
    event, values = winx.read()         # Display Window & wait for an event
    if event == 'Exit' or event == sg.WINDOW_CLOSE_ATTEMPTED_EVENT: # Exit button or upper left X
       break

    if event == '-NAME-' :  # Name Validation
        print("Name Validation")

    if event == '-AGE-' and values['-AGE-'][-1] not in ('0123456789'):  # Age Validation
       winx['-AGE-'].update(values['-AGE-'][:-1]) # delete last char from input
       print("Age Validation")

    if event == '-DATE-':
       print("Date Validation")

    if event == '-UPDATE-':
        # Check for missing fields
        print("Update File")

winx.close()

Watcha Makin?

If you care to share something about your project, it would be awesome to hear what you're building.

I would then check to see that none of the Fields are NULL (empty)

Validate all values of all your Input elements when event "Update" in your event loop.

how do I go back and ask for it to be re-entered ?

IMO, you can call sg.popup or similarities to display a popup window to alarm if validation failed.

If a Field is entered followed by a Carriage Return - is there any way to make it act like the TAB key and go on to the next Field ?
