[英]Python tkinter ttk.Notebook widget error
I have a problem with the Notebook widget with python 3.3.2 使用python 3.3.2的Notebook小部件有问题
This is the code: 这是代码:
gui=Tk()
gui.title("Test")
gui.geometry()
n = ttk.Notebook(gui).grid()
f1 = ttk.Frame(n)
f2 = ttk.Frame(n)
n.add(f1, text='One')
n.add(f2, text='Two')
gui.resizable(width=TRUE, height=TRUE)
mainloop()
and this is the error: 这是错误:
Traceback (most recent call last):
File "C:\Users\SergiX\Desktop\SergiX44's ModTool con sorgente 3.3\SergiX44's ModTool 1.6.4.py", line 179, in <module>
n.add(f1, text='One')
AttributeError: 'NoneType' object has no attribute 'add'
I don't know the reason of the error 我不知道错误的原因
thanks 谢谢
The problem is that you're assigning the result of the grid
function to n
, rather than the Notebook
widget itself. 问题是您将
grid
函数的结果分配给n
,而不是Notebook
小部件本身。 The grid
function always returns None
, so n
has a value of None
, thus the error. grid
函数始终返回None
,因此n
的值为None
,因此为错误。
To fix this, try replacing this line 要解决此问题,请尝试替换此行
n = ttk.Notebook(gui).grid()
with these lines 用这些线条
n = ttk.Notebook(gui)
n.grid()
