1.创建
from tkinter import *
root=Tk()
print(root.pack_slaves())
Label(root,text='pack').pack()
print(root.pack_slaves())
root.mainloop()

2.改变大小
from tkinter import *
root=Tk()
root.geometry('80x80+0+0')
print(root.pack_slaves())
Label(root,text='pack').pack()
print(root.pack_slaves())
root.mainloop()

3.添加多个组件
from tkinter import *
root=Tk()
root.geometry('80x80+0+0')
print(root.pack_slaves())
for i in range(5):
Label(root,text='pack'+str(i)).pack()
print(root.pack_slaves())
root.mainloop()

4.子组件布局
from tkinter import *
root=Tk()
root.geometry('80x80+0+0')
print(root.pack_slaves())
Label(root,text='pack1',bg='red').pack(fill=Y)
Label(root,text='pack2',bg='blue').pack(fill=BOTH)
Label(root,text='pack3',bg='green').pack(fill=X)
print(root.pack_slaves())
root.mainloop()
图片.png
5.组件布局
from tkinter import *
root=Tk()
root.geometry('80x80+0+0')
print(root.pack_slaves())
Label(root,text='pack1',bg='red').pack(fill=Y,expand=1)
Label(root,text='pack2',bg='blue').pack(fill=BOTH,expand=1)
Label(root,text='pack3',bg='green').pack(fill=X,expand=1)
print(root.pack_slaves())
root.mainloop()

6.改变组件布局
from tkinter import *
root=Tk()
root.geometry('80x80+0+0')
print(root.pack_slaves())
Label(root,text='pack1',bg='red').pack(fill=Y,expand=1,side=LEFT)
Label(root,text='pack2',bg='blue').pack(fill=BOTH,expand=1,side=RIGHT)
Label(root,text='pack3',bg='green').pack(fill=X,expand=1,side=LEFT)
print(root.pack_slaves())
root.mainloop()
图片.png
7.组件间距
from tkinter import *
root=Tk()
root.geometry('80x80+0+0')
print(root.pack_slaves())
Label(root,text='pack1',bg='red').pack(fill=Y,expand=1,side=LEFT)
Label(root,text='pack2',bg='blue').pack(fill=BOTH,expand=1,side=RIGHT,padx=10)
Label(root,text='pack3',bg='green').pack(fill=X,expand=1,side=LEFT,pady=10)
print(root.pack_slaves())
root.mainloop()
