I am trying to create a reset button that allows me to reset username details if clicked. How can I achieve this please?
I have tried different methods but I get
Name Error: enter name is not defined
main_window_page = Tk()
main_window_page.title("GA")
main_window_page.geometry("600x600")
entername = StringVar()
enterpassword = StringVar()
Username=tk.Label(text="Username")
Username.pack(pady=1,padx=1)
EnterName=tk.Entry(bd=4,textvariable=entername)
EnterName.pack(pady=5,padx=5)
Reset=tk.Button(text="Reset",command=clearFunc)
Reset.pack(pady=13,padx=13)
main_window_page.mainloop()
def clearFunc():
entername.set("0")
答案 0 :(得分:0)
欢迎堆栈溢出Tobi。
您需要将entername设为全局字符串变量,以便可以在clearFunc子例程中对其进行引用/使用。
global entername
要使clearFunc()将entername的值设置为空,必须将entername的值设置为“”:
entername.set("")
此外,请始终将mainloop放在代码的末尾。
在引用它之前,您还需要定义clearFunc子例程,因此我将其移到了reset按钮之前。
代码:
main_window_page = Tk()
main_window_page.title("GA")
main_window_page.geometry("600x600")
global entername #make it a global string variable
entername = StringVar()
enterpassword = StringVar()
Username=tk.Label(text="Username")
Username.pack(pady=1,padx=1)
EnterName=tk.Entry(bd=4,textvariable=entername)
EnterName.pack(pady=5,padx=5)
def clearFunc():
entername.set("")
Reset=tk.Button(text="Reset",command=clearFunc)
Reset.pack(pady=13,padx=13)
main_window_page.mainloop()
