Python Tkinter中的pack()方法介绍

打包几何图形管理器将小部件打包为行或列。我们可以使用类似的选项填, 扩大和侧控制此几何图形管理器。

相比格经理包管理器在某种程度上受到限制, 但是在一些但很常见的情况下使用起来要容易得多:

  • 将小部件放在框架中(或任何其他容器小部件), 并使其填满整个框架
  • 将许多小部件彼此放在顶部
  • 并排放置许多小部件

代码1:将小部件放入框架中并填充整个框架。我们可以借助扩大和填选项。

# Importing tkinter module
from tkinter import * from tkinter.ttk import *
  
# creating Tk window
master = Tk()
  
# cretaing a Fra, e which can expand according
# to the size of the window
pane = Frame(master)
pane.pack(fill = BOTH, expand = True )
  
# button widgets which can also expand and fill
# in the parent widget entirely
b1 = Button(pane, text = "Click me !" )
b1.pack(fill = BOTH, expand = True )
  
b2 = Button(pane, text = "Click me too" )
b2.pack(fill = BOTH, expand = True )
  
mainloop()

输出如下:

代码2:将小部件彼此并排放置。我们可以通过并排选项来实现。

# Importing tkinter module
from tkinter import *
# from tkinter.ttk import *
  
# creating Tk window
master = Tk()
  
# cretaing a Fra, e which can expand according
# to the size of the window
pane = Frame(master)
pane.pack(fill = BOTH, expand = True )
  
# button widgets which can also expand and fill
# in the parent widget entirely
b1 = Button(pane, text = "Click me !" , background = "red" , fg = "white" )
b1.pack(side = TOP, expand = True , fill = BOTH)
  
b2 = Button(pane, text = "Click me too" , background = "blue" , fg = "white" )
b2.pack(side = TOP, expand = True , fill = BOTH)
  
b3 = Button(pane, text = "I'm also button" , background = "green" , fg = "white" )
b3.pack(side = TOP, expand = True , fill = BOTH)
  
mainloop()

输出如下:

代码3:

# Importing tkinter module
from tkinter import *
# from tkinter.ttk import *
  
# creating Tk window
master = Tk()
  
# cretaing a Fra, e which can expand according
# to the size of the window
pane = Frame(master)
pane.pack(fill = BOTH, expand = True )
  
# button widgets which can also expand and fill
# in the parent widget entirely
b1 = Button(pane, text = "Click me !" , background = "red" , fg = "white" )
b1.pack(side = LEFT, expand = True , fill = BOTH)
  
b2 = Button(pane, text = "Click me too" , background = "blue" , fg = "white" )
b2.pack(side = LEFT, expand = True , fill = BOTH)
  
b3 = Button(pane, text = "I'm also button" , background = "green" , fg = "white" )
b3.pack(side = LEFT, expand = True , fill = BOTH)
  
mainloop()

输出如下:
