Question

我一直在寻找堆栈溢出多年来试图找到答案，但我无法得到任何工作，因此我问这个问题。我有一个带有三个按钮和一个标签的小程序，它们都在网格中。我想知道无论尺寸或形状如何，按钮和标签相对于框架都保持不变。与我调整图像大小相似，所有内容都保持不变。

这是我的代码：

from tkinter import *

class Window(Frame): #All the stuff for the GUI
   def __init__(self, master = None):
      Frame.__init__(self, master)
      self.master = master
      self.init_window()
      self.grid()

   def init_window(self):
      self.master.title("EncryptDecrypt")
      self.pack(fill = BOTH, expand = 1)

      quitButton = Button(self, text = "Quit", command = self.client_exit, width = 10, height = 5) #Quit Button
      quitButton.grid(row = 0, column = 0, sticky = W)

      encryptModeButton = Button(self, text = "Encrypt", command = lambda: self.execute("decrypted.txt", "encrypted.txt", 1, 0), width = 10, height = 5) #Encrypt Button
      encryptModeButton.grid(row = 0, column = 1, sticky = W)

      decryptModeButton = Button(self, text = "Decrypt", command = lambda: self.execute("encrypted.txt", "decrypted.txt", 0, 1), width = 10, height = 5) #Decrypt button
      decryptModeButton.grid(row = 0, column = 2, sticky = W)

      myLabel = Label(self, text = "Select The Action You Wish To Undertake", font = ("Purisa", 15))
      myLabel.grid(row = 0, column = 3) 
root = Tk()
root.geometry("610x80")

app = Window(root)   
root.mainloop()

很抱歉，如果答案很明显，我已经尝试了pack()

There's a good tutorial to grid packer。只需滚动“处理调整大小”，您就会注意到如何使用sticky选项并配置列/行对的weight。

让我们试试grid打包器的例子：

from tkinter import *

class Window(Frame): #All the stuff for the GUI
   def __init__(self, master = None):
      Frame.__init__(self, master)
      self.master = master
      self.master.minsize(width=650, height=80)
      self.configure(relief=RAISED, borderwidth=10)
      self.init_window()
      self.grid(sticky = NSEW)

   def init_window(self):
      self.master.title("EncryptDecrypt")
      # configure weights; note: that action need for each container!
      self.master.rowconfigure(0, weight=1)
      self.master.columnconfigure(0, weight=1)
      self.rowconfigure(0, weight=1)
      for i in range(4):
        self.columnconfigure(i, weight=1)

      quitButton = Button(self, text = "Quit", width = 10, height = 5) #Quit Button
      quitButton.grid(row = 0, column = 0, sticky = NSEW)

      encryptModeButton = Button(self, text = "Encrypt", width = 10, height = 5) #Encrypt Button
      encryptModeButton.grid(row = 0, column = 1, sticky = NSEW)

      decryptModeButton = Button(self, text = "Decrypt", width = 10, height = 5) #Decrypt button
      decryptModeButton.grid(row = 0, column = 2, sticky = NSEW)

      myLabel = Label(self, text = "Select The Action You Wish To Undertake", font = ("Purisa", 15))
      myLabel.grid(row = 0, column = 3, sticky = NSEW)



root = Tk()
root.geometry("650x80")

app = Window(root)
root.mainloop()

如您所见 - 我刚刚添加了sticky=NSEW和columnconfigure / rowconfigure，看起来像您希望的那样！这方面的缺点是需要配置每个容器！

但是，在pack经理中，有更直观且执行相同的角色选项 - fill和expand！

from tkinter import *

class Window(Frame): #All the stuff for the GUI
   def __init__(self, master = None):
      Frame.__init__(self, master)
      self.master = master
      self.master.minsize(width=650, height=80)
      self.configure(relief=RAISED, borderwidth=10)
      self.init_window()
      self.pack(fill=BOTH, expand=True)

   def init_window(self):
      self.master.title("EncryptDecrypt")

      quitButton = Button(self, text = "Quit", width = 10, height = 5) #Quit Button
      quitButton.pack(fill=BOTH, side=LEFT, expand=True)

      encryptModeButton = Button(self, text = "Encrypt", width = 10, height = 5) #Encrypt Button
      encryptModeButton.pack(fill=BOTH, side=LEFT, expand=True)

      decryptModeButton = Button(self, text = "Decrypt", width = 10, height = 5) #Decrypt button
      decryptModeButton.pack(fill=BOTH, side=LEFT, expand=True)

      myLabel = Label(self, text = "Select The Action You Wish To Undertake", font = ("Purisa", 15))
      myLabel.pack(fill=BOTH, side=LEFT, expand=True)



root = Tk()
root.geometry("650x80")

app = Window(root)
root.mainloop()

使用什么是您的选择！有一个关于调整大小，网格和包装的好主题！ Take a look
