Python tkinter顶层窗口内的输入框

我已经编写了一个代码来显示tkinter中顶级窗口中的Entry小部件，但在运行它时它并没有显示任何内容。 下面是我调用顶级窗口的代码：

#file: app.py

# enter new racer
btnNewRacer = Button(app, text = "Enter New Racer", style = 'W.TButton', command = EnterRacer)
btnNewRacer.grid(row = 0, column = 0, pady = 50, padx = 50)

这是我为Entry widget编写的代码：

#file: new_racer.py

def EnterRacer(): 
      
    # Toplevel object which will  
    # be treated as a new window 
    racerWindow = Toplevel() 
    racerWindow['background']='#2A3132'
  
    # sets the title of the 
    # Toplevel widget 
    racerWindow.title("Enter New Racer") 
  
    # sets the geometry of toplevel 
    racerWindow.geometry("700x500") 
  
    # A Label widget to show in toplevel 
    Label(racerWindow, text ="Enter new racer window").pack()
    Label(racerWindow, text="First Name").pack()
    Label(racerWindow, text="Last Name").pack().grid(row=5)

    entry_1 = Entry(racerWindow)
    entry_1.pack()
    entry_1.grid(row=5)

---

当我运行app.py并单击“输入新赛车手”按钮时，我没有看到任何输入小部件。有人能帮忙吗？谢谢。

这里的问题是，您不能将

.pack（）

和

.grid（）

组合使用。您只需使用其中一个

您可以将功能更改为：

用于

.pack（）

    # Toplevel object which will  
    # be treated as a new window 
    racerWindow = Toplevel() 
    racerWindow['background']='#2A3132'

    # sets the title of the 
    # Toplevel widget 
    racerWindow.title("Enter New Racer") 

    # sets the geometry of toplevel 
    racerWindow.geometry("700x500") 

    # A Label widget to show in toplevel 
    Label(racerWindow, text ="Enter new racer window").pack()
    Label(racerWindow, text="First Name").pack()
    Label(racerWindow, text="Last Name").pack()

    entry_1 = Entry(racerWindow)
    entry_1.pack()

def EnterRacer():
    # Toplevel object which will  
    # be treated as a new window 
    racerWindow = Toplevel() 
    racerWindow['background']='#2A3132'

    # sets the title of the 
    # Toplevel widget 
    racerWindow.title("Enter New Racer") 

    # sets the geometry of toplevel 
    racerWindow.geometry("700x500") 

    # A Label widget to show in toplevel 
    Label(racerWindow, text ="Enter new racer window").grid(row=0,column=0)
    Label(racerWindow, text="First Name").grid(row=0,column=1)
    Label(racerWindow, text="Last Name").grid(row=0,column=2)

    entry_1 = Entry(racerWindow)
    entry_1.grid(row=1,column=0,columnspan=3,sticky=E+W)

用于

.grid（）

    # Toplevel object which will  
    # be treated as a new window 
    racerWindow = Toplevel() 
    racerWindow['background']='#2A3132'

    # sets the title of the 
    # Toplevel widget 
    racerWindow.title("Enter New Racer") 

    # sets the geometry of toplevel 
    racerWindow.geometry("700x500") 

    # A Label widget to show in toplevel 
    Label(racerWindow, text ="Enter new racer window").pack()
    Label(racerWindow, text="First Name").pack()
    Label(racerWindow, text="Last Name").pack()

    entry_1 = Entry(racerWindow)
    entry_1.pack()

def EnterRacer():
    # Toplevel object which will  
    # be treated as a new window 
    racerWindow = Toplevel() 
    racerWindow['background']='#2A3132'

    # sets the title of the 
    # Toplevel widget 
    racerWindow.title("Enter New Racer") 

    # sets the geometry of toplevel 
    racerWindow.geometry("700x500") 

    # A Label widget to show in toplevel 
    Label(racerWindow, text ="Enter new racer window").grid(row=0,column=0)
    Label(racerWindow, text="First Name").grid(row=0,column=1)
    Label(racerWindow, text="Last Name").grid(row=0,column=2)

    entry_1 = Entry(racerWindow)
    entry_1.grid(row=1,column=0,columnspan=3,sticky=E+W)

这只是网格化的一种方式，您可以通过更改行和列参数来使用自己的方式。如果有任何疑问，请告诉我：D

干杯

我不知道这是否正确，但我从未见过

.pack（）.grid（）

它有什么作用？你是在包装它，然后把它网格化，就做一个？如果我没有错的话，你也没有看到你的“姓氏”标签？这可能是个错误，但我可以看到所有的三个标签。只有条目小部件未显示@CoolCloudI立即获得了

AttributeError:“非类型”对象没有属性“网格”

，您正在混合

pack

和

grid

，并尝试在已打包的对象上执行

grid

。您想放置它还是使用网格？还是打包？错误：

AttributeError:'NoneType'对象没有属性'grid'
