If I understand the PythonCard model.py source correctly, the
Application object initializes the Background object but you have
created an __init__ method in Minimal so that gets called instead.
You don't then call the Background __init__ which does various other
start-up tasks and I'm guessing that is why the application does not
work.

(You don't say what is wrong when you run it, but trying it here I just
get a blank window).

If you just want to add the STAY_ON_TOP style then try the
following...it seems to work here:

from PythonCard import model

class Minimal(model.Background):
    
    def __init__(self, aParent, aBgRsrc):
        aBgRsrc.style = ['wx.DEFAULT_FRAME_STYLE','wx.STAY_ON_TOP']
        model.Background.__init__(self, aParent, aBgRsrc)
        

if __name__ == '__main__':
    app = model.Application(Minimal)
    app.MainLoop()

aBgRsrc is the application bacground resource properties from the
resource file. Adding an extra style is a bit tricky, but since you
have set it to 'resizeable' and the Background object translates that
into wx.DEFAULT_FRAME_STYLE you can replace that with the two item
list. The Background object has been coded to eval() each item in the
list (hence I've made them strings) and bitwise OR them.
