• [X] Run your program outside of your debugger (from a command line)
• [X] Searched through Issues (open and closed) to see if already reported Issues.PySimpleGUI.org
• [X] Have upgraded to the latest release of PySimpleGUI on PyPI (lastest official version)

Detailed Description

When dealing with multiple windows, i tracked the focused window using the <FocusIn> and <FocusOut> events. When clicking a window, these events get called normally. When grabbing a window by the Title bar and moving it around however, it is then focused without the events. Simply clicking on the Title Bar however focuses it with the events.

Code To Duplicate

A short program that isolates and demonstrates the problem

import PySimpleGUI as sg


#create two layouts
win1Layout = [
    [sg.Text('Win1')],
]
win2Layout = [
    [sg.Text('Win2')],
]

#size is important to make aenough room on the title bar to grab the windows
win1 = sg.Window('Win1', layout=win1Layout, size=(300, 100), finalize=True)
win2 = sg.Window('Win2', layout=win2Layout, size=(300, 100), finalize=True)

#bind the events to the windows
win1.bind('<FocusIn>', "WIN1FocusIn")
win1.bind('<FocusOut>', "WIN1FocusOut")
win2.bind('<FocusIn>', "WIN2FocusIn")
win2.bind('<FocusOut>', "WIN2FocusOut")


while True:
    activeWindow, event, values = sg.read_all_windows(timeout=500)

    if event == sg.WIN_CLOSED:
        break

    if not event == "__TIMEOUT__":
        print(event)

Watcha Makin?

Im a Student working in a company between semesters and have been tasked with creating a program to write certain Tables to the EEPROM of the devices we are selling

[jason990420]

It looks it is caused by the argument timeout.

Following action can make '<FocusIn>' work better or work fine.

• Remove argument timeout, or
• Set values of timeout to higher, like timeout=1000.

This issue maybe something related to issue #5495

[PySimpleGUI]

Is this related to the same focus / entry problem that started in 8.6.12 that we noticed with tooltips?

EDIT - AH! RIGHT! I remember @nachocho also reporting problems similar. I'm wondering if these are 8.6.12 specific and if 8.6.13 may fix them. I believe 8.6.13 may have fixed or improved the disappearing window problem on the Mac, but have not had enough time to verify it.
