    Welcome to the "core" PySimpleGUI code....

    It's a mess.... really... it's a mess internally... it's the external-facing interfaces that
    are not a mess.  The Elements and the methods for them are well-designed.
    PEP8 - this code is far far from PEP8 compliant. 
    It was written PRIOR to learning that PEP8 existed. 

    The variable and function naming in particular are not compliant.  There is
    liberal use of CamelVariableAndFunctionNames.  If you've got a serious enough problem with this
    that you'll pass on this package, then that's your right and I invite you to do so.  However, if
    perhaps you're a practical thinker where it's the results that matter, then you'll have no
    trouble with this code base.  There is consisency however.  

    I truly hope you get a lot of enjoyment out of using PySimpleGUI.  It came from good intentions.
