Tkinter Toplevel widget get user input multiple times

Question

I am trying to get user input using a Toplevel widget in order to create an order but the submit button does not work as expected please assist.

def spawn_window(self):
    top = Toplevel()
    top.title("Available Electronics")
    self.entrytext = StringVar()
    Entry(top, textvariable=self.entrytext).pack()
    button = Button(top, text="Dismiss", command=top.destroy)
    button.pack(side='right')
    submit = Button(top, text ="Submit", command = self.datainput)
    submit.pack(side='left')



def datainput(self):
    input_var = self.entrytext.get()
    self.devices.append(input_var)

What was the desired behavior, and what is the current behavior? — Gilbert Allen, May 05 '16 at 12:40
wanted the text box to turn blank as soon as the submit button was clicked in order to create room for another entry — dmn8, May 05 '16 at 13:21
Did you try adding the command to remove the old data? How do you expect the widget to know you want it to be cleared? — Bryan Oakley, May 05 '16 at 13:45

"wanted the text box to turn blank as soon as the submit button was clicked in order to create room for another entry" now its clear what you really want!

In your datainput-method just clear your stringvar at the end, like this:

def datainput(self):
    input_var = self.entrytext.get()
    self.devices.append(input_var)
    self.entrytext.set("")
