1、鼠标点击事件：

import tkinter

win = tkinter.Tk()
win.title("窗体")
win.geometry("400x400+200+50")

#鼠标左键
#鼠标右键
#鼠标滑轮
#鼠标左键双击
#鼠标中键双击
#鼠标右键双击
#鼠标左键三击
def func(event):
	print(event.x,event.y)

button1 = tkinter.Label(win,text="leftmouse button")
#bind 给控件绑定事件
button1.bind("",func)
button1.pack()
win.mainloop()

2、鼠标移动事件：

import tkinter

win = tkinter.Tk()
win.title("窗体")
win.geometry("400x400+200+50")

label = tkinter.Label(win,text="hello")
label.pack()

#左键移动
#右键移动
#中键移动
def func(event):
	print(event.x,event.y)
label.bind("",func)


win.mainloop()

3、鼠标释放事件：

import tkinter

win = tkinter.Tk()
win.title("窗体")
win.geometry("400x400+200+50")

label = tkinter.Label(win,text="sunck is a man",bg="red")
label.pack()

#释放鼠标左键
#释放鼠标右键
#释放鼠标中键


def func(event):
	print(event.x,event.y)
label.bind("",func)



win.mainloop()

4、组合按键：

import tkinter

win = tkinter.Tk()
win.title("窗体")
win.geometry("400x400+200+50")

def func(e):
	print("e.char=",e.char)
	print("e.keycode=",e.keycode)

win.bind("",func)
#同时按下shift和方向上键


win.mainloop()

 5、相对布局：

import tkinter

win = tkinter.Tk()
win.title("窗体")
win.geometry("400x400+200+50")

label1 = tkinter.Label(win,text="good",bg="blue")
label2 = tkinter.Label(win,text="nice",bg="red")
label3 = tkinter.Label(win,text="cool",bg="pink")

#相对布局
#Both = Y
label1.pack(fill = tkinter.Y,side=tkinter.LEFT)
label2.pack(fill = tkinter.X,side=tkinter.TOP)
label3.pack()

win.mainloop()

6、绝对布局：

import tkinter

win = tkinter.Tk()
win.title("窗体")
win.geometry("400x400+200+50")

label1 = tkinter.Label(win,text="good",bg="blue")
label2 = tkinter.Label(win,text="nice",bg="red")
label3= tkinter.Label(win,text="cool",bg="pink")

#绝对布局,窗口的变化对位置没有影响
label1.place(x =10,y=10)
label2.place(x =50,y=50)
label3.place(x =100,y=100)



win.mainloop()

7、表格布局：

import tkinter

win = tkinter.Tk()
win.title("窗体")
win.geometry("400x400+200+50")

label1 = tkinter.Label(win,text="good",bg="blue")
label2 = tkinter.Label(win,text="nice",bg="red")
label3 = tkinter.Label(win,text="cool",bg="pink")
label4 = tkinter.Label(win,text="handsome",bg="green")

#表格布局：
label1.grid(row=0,column=0)
label2.grid(row=0,column=1)
label3.grid(row=1,column=0)
label4.grid(row=1,column=1)

win.mainloop()

8、表格数据：

import tkinter
from tkinter import ttk

win = tkinter.Tk()
win.title("窗体")
win.geometry("600x400+200+50")

tree = ttk.Treeview(win)
tree.pack()
tree["columns"] = ("姓名","年龄","身高","体重")
tree.column("姓名",width=100)
tree.column("年龄",width=100)
tree.column("身高",width=100)
tree.column("体重",width=100)

tree.heading("姓名",text="姓名-name")
tree.heading("年龄",text="年龄-age")
tree.heading("身高",text="身高-height")
tree.heading("体重",text="体重-wight")

#添加数据
tree.insert("",0,text="line1",values=("dx","22","166","55"))
tree.insert("",1,text="line1",values=("ll","21","170","66"))

win.mainloop()

9、树状层级目录：

主函数：

import tkinter
import os
from treeWindows import TreeWindows
from infoWindows import InfoWindows

win = tkinter.Tk()
win.title("窗体")
win.geometry("600x400+200+50")

path = "F:\\学习存放\\untitled"
infoWin = InfoWindows(win)
treeWin = TreeWindows(win,path,infoWin)

信息窗口：

import tkinter
from tkinter import ttk
import os


class InfoWindows(tkinter.Frame):
	def __init__(self,master):
		frame = tkinter.Frame(master)
		frame.grid(row=0, column=1)


		self.ev = tkinter.Variable()
		#创建一个Entry
		self.entry = tkinter.Entry(frame,textvariable=self.ev)
		self.entry.pack()

		#创建一个text
		self.txt=tkinter.Text(frame)
		self.txt.pack()

树状目录窗口：

import tkinter
from tkinter import ttk
import os

class TreeWindows(tkinter.Frame):
	def __init__(self,master,path,otherWin):
		frame = tkinter.Frame(master)
		frame.grid(row=0, column=0)

		self.otherWin = otherWin

		self.tree = ttk.Treeview(frame)
		self.tree.pack(side=tkinter.LEFT,fill=tkinter.Y)
		self.tree.pack()

		root = self.tree.insert("","end",text=self.getLastPath(path),open=True,
		                        values=(path))
		self.loadTree(root,path)

		#滚动条
		self.sy = tkinter.Scrollbar(frame)
		self.sy.pack(side=tkinter.RIGHT,fill=tkinter.Y)
		self.sy.config(command=self.tree.yview)
		self.tree.config(yscrollcommand=self.sy.set)

		#绑定事件
		self.tree.bind("<>",self.func)

	def func(self,event):
		#widget触发事件的构建
		self.v = event.widget.selection()
		for sv in self.v:
			file = self.tree.item(sv)["text"]
			self.otherWin.ev.set(file)
			apath = self.tree.item(sv)["values"][0]
			print(apath)


	def loadTree(self,parent,parentPath):
		for FileName in os.listdir(parentPath):
			absPath = os.path.join(parentPath,FileName)

			#插入树枝
			treey = self.tree.insert(parent,"end",text=self.getLastPath(absPath),values=(absPath))
			#判断是否是目录
			if os.path.isdir(absPath):
				self.loadTree(treey,absPath)





	def getLastPath(self,path):
		pathList = os.path.split(path)
		return pathList[-1]
