问题描述
限时送ChatGPT账号..我刚刚开始使用 Python 的 tkinter
GUI 工具.在我的代码中,我创建了一个带有一个按钮的简单 GUI,如果用户单击该按钮,我想向用户显示一个 messagebox
.
目前,我使用 tkinter.messagebox.showinfo
方法.我使用 IDLE 在 Windows 7 计算机上编码.如果我从 IDLE 运行代码一切正常,但是如果我尝试在 Python 3 解释器中独立运行它,它就不再工作了.相反,它将此错误记录到控制台:
AttributeError:'module' 对象没有属性 'messagebox'
你对我有什么建议吗?我的代码是:
导入tkinter类 simpleapp_tk(tkinter.Tk):def __init__(self,parent):tkinter.Tk.__init__(self,parent)self.parent = 父母self.temp = 假自我初始化()定义初始化(自我):self.geometry()self.geometry("500x250")self.bt = tkinter.Button(self,text="Bla",command=self.click)self.bt.place(x=5,y=5)定义点击(自我):tkinter.messagebox.showinfo("blab","bla")如果 __name__ == "__main__":app = simpleapp_tk(无)app.title('我的应用程序')app.mainloop()
解决方案 messagebox
以及其他一些模块,例如 filedialog
,在您 导入 tkinter
.根据需要使用 as
和/或 from
显式导入它.
I have just started working with Python's tkinter
GUI tool. In my code I create an simple GUI with one button and I want to show the user a messagebox
if they click on the button.
Currently, I use the tkinter.messagebox.showinfo
method for it. I code on a Windows 7 computer using IDLE. If I run the code from IDLE everything works fine, but if I try to run it standalone in the Python 3 interpreter it doesn't work any more. Instead it logs this error to the console:
AttributeError:'module' object has no attribute 'messagebox'
Do you have any tips for me? My code is:
import tkinter
class simpleapp_tk(tkinter.Tk):
def __init__(self,parent):
tkinter.Tk.__init__(self,parent)
self.parent = parent
self.temp = False
self.initialize()
def initialize(self):
self.geometry()
self.geometry("500x250")
self.bt = tkinter.Button(self,text="Bla",command=self.click)
self.bt.place(x=5,y=5)
def click(self):
tkinter.messagebox.showinfo("blab","bla")
if __name__ == "__main__":
app = simpleapp_tk(None)
app.title('my application')
app.mainloop()
解决方案
messagebox
, along with some other modules like filedialog
, does not automatically get imported when you import tkinter
. Import it explicitly, using as
and/or from
as desired.
>>> import tkinter
>>> tkinter.messagebox.showinfo(message='hi')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'messagebox'
>>> import tkinter.messagebox
>>> tkinter.messagebox.showinfo(message='hi')
'ok'
>>> from tkinter import messagebox
>>> messagebox.showinfo(message='hi')
'ok'
