### All Widgets No Context Manager
Same form as above with no Context Manager. Use this pattern when you are in a hurry, don't have time to do things right, or it's throw-away code.... the legit use of this design is when you have non-blocking forms that update the form far away in the code from the form creation. Perhaps you show your form, get some input, then down in your event loop you want to execute another read or have an event loop where form.ReadNonBlocking is called.
Turning your form into forms that use a Contact Manage is quite easy. Change your FlexForm call from
form = sg.FlexForm('Everything bagel', default_element_size=(40, 1), grab_anywhere=False)
to
with sg.FlexForm('Everything bagel', default_element_size=(40, 1), grab_anywhere=False) as form:
Be sure and place the with statement at the top of your GUI code and indent you code under it.
