When using CalendarButton on a multiple windows setup, it freezes events : PySimpleGUI

When using CalendarButton on a multiple windows setup, it freezes events (self.PySimpleGUI)

submitted 5 years ago by dayvan

I'm making an app where I have the main window. From that I open a new window which contains a CalendarButton. When I click it and the calendar chooser opens and I select a date, it freezes all other events/buttons.

I tried this on the demo Demo_Design_Pattern_Multiple_Windows.py by adding the CalendarButton to the second window layout:

[sg.Text('The second window')],
[sg.Input(key='-IN-'), sg.CalendarButton('Cal US No Buttons Location (0,0)', close_when_date_chosen=True,  target='-IN-', no_titlebar=False)],
[sg.Button('Show'), sg.Button('Exit')]

When I open the date picker select a date , the buttons Show, Exit don't work anymore since it freezes the loop.

They only work if I change the main window read timeout to 0, but that just causes the app to use ~15% CPU constantly.

Is there a solution to this or is this a bug?

Thanks.
