Radio Buttons

HEAD-Ex Logistics and Transportation¶

Model is the stored data
Vision is the featured radio button
Control is the tkinter code that manages all this

Label(app, text = 'Destino: ').pack()
destino = StringVar()
destino.set(None)
Radiobutton(app, variable = destino , text = 'Cambridge , MA', value = 'Cambridge , MA').pack()
Radiobutton(app, variable = destino , text = 'Cambridge , UK', value = 'Cambridge , UK').pack()
Radiobutton(app, variable = destino , text = 'Seattle, WA', value = 'Seattle , WA').pack()
