getting selected value of Combobox python

Question

Hi I have the following code

def create(self):
    geo = StringVar()
    city = ttk.Combobox(gui, textvariable=geo,state=\"readonly\")
    city.config(values=se         


        

Answer 1

this worked for me :

def create(self):
        print(self.geo)
        strgeo="\n".join(str(x) for x in self.geo)

        print(strgeo)
        city = ttk.Combobox(gui, textvariable=self.stringGeo, state="readonly",width=30)
        city.config(values=strgeo)
        city.pack()
        city.bind("<<ComboboxSelected>>",self.selectedCity)

    def selectedCity(self,event):
        selected=self.stringGeo.get()

Answer 2

As it stands you cannot retrieve the value of geo, since it is not defined as an attribute of your class, but in the local scope of create. What you can do is declaring geo as a static attribute and then call it from within your method when you need it.

class(object):

    geo = StringVar()
    geos = ('NY','LA','RY','...')

    def __init__(self,#....
        #...

    def create(self):
        city = ttk.Combobox(gui, textvariable=self.geo,state="readonly")
        city.config(values=self.geos) 
        city.pack()
        city.bind("<<ComboboxSelected>>", self.cityselection)


    def cityselection(self,event):
        selected=self.geo.get()
        print(selected)

Actually, event is not what you think it is.
