Python 3.6 - 根据帧大小调整 Tkinter 按钮的大小

分类: 技术问答 • 2022-07-20 13:11:48
问题描述：

我多年来一直在寻找堆栈溢出的问题，试图找到答案，但我无法解决任何问题，因此我提出了这个问题.我有一个带有三个按钮和一个标签的小程序，它们位于网格中.我想知道按钮和标签的大小或形状如何相对于框架保持不变.类似于如果我调整图像大小，一切都会保持相同的大小.

I have been looking around on stack overflow for ages trying to find the answer to this but I just can't get anything to work, therefore I am asking this question. I have a little program with three buttons and a label, and they are in a grid. I was wondering how no matter the size or shape the buttons and label would stay the same relative to the frame. Similar to if I resized an image, everything stays the same size.

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()

对不起，如果答案很明显，我已经尝试过 pack()

Sorry if the answer is obvious, I have already tried pack()

有一个很好的教程网格打包器.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.

There's a good tutorial to grid packer. Just scroll over "Handling Resize" and you would notice how to use sticky option and configure weight of column/row pair.

那么让我们用 grid 打包器试试你的例子:

So let's try your example with grid packer:

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 - 我刚刚添加了一个 sticky=NSEW 和 columnconfigure/rowconfigure 并且看起来像您希望的那样工作！缺点是需要配置每个容器！

As you see - I just added a sticky=NSEW and columnconfigure/rowconfigure and seems like it works like you wish! The weak side of this is the need to configure each container!

但是在这里，在 pack 管理器中，有更直观和执行相同角色的选项 - fill 和 expand！

But here, in pack manager, there're more intuitive and performing the same role options - fill and 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()

用什么是你的选择！还有一个关于调整大小、网格和打包的好话题！看看

What to use is your choice! And there're a good topic about resizing, grid and pack! Take a look
