Question

python tkinter 使用canvas的问题

def __init__(self,eventManager): self.__eventManager = eventManager self.root = Tk() var1 =StringVar() var2 = StringVar() self.root.geometry('415x320') self.root.title("login_ui") #背景图 self.canvas = tk.canvas(self.root, width=520, height=150, bg='white') img = itk.PhotoImage(file="/home/lxy/PycharmProjects/Chat_room/Chatingroom/log_head.gif") self.canvas.create_image(210, 100, image=img) self.canvas.grid(row=0, column=0, columnspan=2, padx=1, pady=3)
出错原因是

File "/home/lxy/PycharmProjects/Chat_room/chatingroom/ui/login.py", line 32, in __init__
self.canvas = tk.canvas(self.root, width=520, height=150, bg='white')
AttributeError: 'module' object has no attribute 'canvas'

Answer 1

如果tk是正确的tkinter模块

    
self.canvas = tk.Canvas(self.root, width=520, height=150, bg='white') 
                 ^大写

方法名要写对

追问

谢谢，我用pyinstaller在做尝试打包的时候因为需要用到PIL库，所以我把PIL也复制进去了，回到pycharm界面发现ImageTk报了一个Cannot find reference 'ImageTk' in '__init__.py' 错误，这个怎么解决，初学python,，不太了解
