Question

我在Entry小部件中添加了一些值，并在提交按钮时尝试使用get函数获取该值。但是他们得到了跟随错误，请任何人帮助我。

'UpgradeApp' object has no attribute '_tk'

class UpgradeApp:
    def __init__(self):
        self.root = tk.Tk()
        self.newvalue = tk.StringVar
        self.input()

    def input(self):
        tk.Label(self.root, text="IP Address", relief="groove" ).grid(row=0, columnspan =3, sticky = tk.NSEW)
        ip_entry = ttk.Entry(self.root, textvariable = self.newvalue)
        ip_entry.grid(column=3, row=0, sticky=tk.W, padx=5, pady=5)
        connect = tk.Button(self.root, text="conn", relief="groove", command= self.onclickconnect)
        connect.grid(row=1, padx = 5, pady = 5, column = 0)
        #connect.bind('<Button-1>',self.onclick)
        tk.Button(self.root, text="dlt", relief="groove").grid(row=1, padx = 5, pady = 5, column =1)
        tk.Button(self.root, text="clr", relief="groove").grid(row=1, padx = 5, pady = 5, column =2)

    def onclickconnect(self):
        ip = self.newvalue.get(self)
        Node(ip,True, True)

if __name__ == "__main__":
    app = UpgradeApp()
    app.root.mainloop()

而不是self.newvalue = tk.StringVar放self.newvalue = tk.StringVar()和StringVar.get()不会接受任何参数，所以它应该是：

def onclickconnect(self):
    #ip = self.newvalue.get(self)
    ip = self.newvalue.get()
    Node(ip,True, True)

＆＃39; UpgradeApp＆＃39;对象没有属性＆＃39; _tk＆＃39;
