:{ AttributeError: 'int' 对象在 Python 中没有属性 'config'

如何解决:{ AttributeError: 'int' 对象在 Python 中没有属性 'config'

这是我的代码，我有一个带有 config() 方法的问题，当我将它与画布一起使用时，它对我不起作用，它给了我这个错误： AttributeError: 'int' 对象没有属性 'config' 所以请帮助我，因为我卡在这里....

from tkinter import ttk
from tkinter import filedialog

root = Tk()
root.title('3R')
root.geometry('350x300')
root.columnconfigure(0,weight=1)

myCanvas = Canvas(root,width=350,height=300)
myCanvas.pack(fill='both',expand=True)

#File location
Folder_Name =""
def openLocation():
    global Folder_Name
    Folder_Name = filedialog.askdirectory()
    if(len(Folder_Name))>1:
        LocError.config(text=Folder_Name,fg='green')
    else:
        LocError.config(text='Please Choose Folder!!',fg = 'red')
LocError = myCanvas.create_text(175,120,text='You must select a location',fill='red',font=('jost',10))
#Button for location
SaveLoc = Button(root,text='Choose Path',command = openLocation)
myCanvas.create_window(130,87,anchor='nw',window=SaveLoc)

root.mainloop()```

解决方法

您必须按如下方式更改您的 if 语句：

if len(Folder_Name) > 1:
    myCanvas.itemconfig(LocError,text=Folder_Name,fill='green')
else:
    myCanvas.itemconfig(LocError,text='Please Choose Folder!!',fill='red')

itemconfig 获取画布项目的 id 或标签并编辑它的属性。画布的 fg 也没有 text 选项，因此将其更改为 fill。

这是工作代码：

from tkinter import *
from tkinter import ttk
from tkinter import filedialog

root = Tk()
root.title("3R")
root.geometry("350x300")
root.columnconfigure(0,weight=1)

myCanvas = Canvas(root,width=350,height=300)
myCanvas.pack(fill='both',expand=True)

#File location
Folder_Name = ""
def openLocation():
    global Folder_Name,myCanvas,LocError
    Folder_Name = filedialog.askdirectory()
    myCanvas.delete(LocError) # Delete the old sprite
    if len(Folder_Name) > 1:
        # Create a new sprite with the correct parameters:
        LocError = myCanvas.create_text(175,120,fill="green",font=("jost",10))
    else:
        # Create a new sprite with the correct parameters:
        LocError = myCanvas.create_text(175,text="Please Choose Folder!!",fill="red",10))
LocError = myCanvas.create_text(175,text="You must select a location",10))
#Button for location
SaveLoc = Button(root,text="Choose Path",command=openLocation)
myCanvas.create_window(130,87,anchor="nw",window=SaveLoc)

root.mainloop()

变量 LocError 是一个整数。它用于识别精灵（用于文本）。为了改变它，我删除了它并用正确的文本/填充创建了一个新的。
