日程处理

目标是输入个文本文件关于日程的，就能够到时间的时候显示出来，在ubuntu系统上运行。

包括以下几点：

1.了解Tkinter。

1.1 参考文献自己制作Python IDEL

1.1.1 制作最简单的文本框和输出。

#!/usr/bin/env python

# -*- coding:utf-8 -*-

import Tkinter as tk

#导入Tkinter模块

#创建一个类

class Application(tk.Frame):

#__init__初始化函数，包含了pack即填充方式。

def __init__(self, master=None):

tk.Frame.__init__(self, master)

self.pack()

#调用createWidgets()方法

self.createWidgets()

def createWidgets(self):

#定义部件1 hi_there模块，设置为button

self.hi_there = tk.Button(self)

self.hi_there["text"] = "Hello World\n(click me)"

self.hi_there["command"] = self.say_hi

self.hi_there.pack(side="top")

#定义部件2 QUIT模块，设置为button

self.QUIT = tk.Button(self, text="QUIT", fg="red",

command=root.destroy)

self.QUIT.pack(side="bottom")

def say_hi(self):

print("hi there, everyone!")

#获取tk实例

root = tk.Tk()

#构造类

app = Application(master=root)

#开始实例化

app.mainloop()

1.1.2 上面的pack是定义填充方式，widget.pack( pack_options )，其中

expand: 当设置为true，部件扩展填充，否则不能使用任何部件的母空间.

fill: 确定是否部件填补分配任何额外的空间，或保持其自己的最小尺寸：无(默认)和X(只填写水平)Y(只填写垂直)，或两者兼而有之(填充横向和纵向).

side: 决定哪方父widget包对TOP(默认)，下，左，或右.

1.1.3 注意在python2.7中lambda表达式不能直接使用print函数，需要先自定义一个函数然后调用

1.1.4 引入tkFiledialog的时候可以参考文献tkFiledialog引入

from tkFileDialog import *

2.功能模块

2.1 读写CSV文件。

参考CSV操作来写信息到文件中。

2.2 需要定义类方便读写这个CSV文件。

参考类定义，因为需要写入sequence对象，所以在这个类中需要定义类似如下结构：

class stepF:

mID = 0

mTimeStamp = datetime(1990,5,11,8,8,8)

mDuration = 0

mParentTask = 0

mSubTask = 1

mPriority = 0

mItem = "GT,xy"

def getSeq(self):

return [self.mID,self.mTimeStamp,self.mDuration,self.mParentTask,

self.mSubTask,self.mPriority,self.mItem]

最后写CSV如下，定义了那个getSeq函数用来在写入的时候调用：

#!/usr/bin/env python

# -*- coding: UTF-8 -*-

import csv

from datetime import *

'''csv文件操作'''

csvfile = file('ss.txt','w')

writer = csv.writer(csvfile)

writer.writerow(['ID','TimeStamp','Duration','ParentTask'

,'SubTask','Priority','Item'])

data = []

class stepF:

mID = 0

mTimeStamp = datetime(1990,5,11,8,8,8)

mDuration = 0

mParentTask = 0

mSubTask = 1

mPriority = 0

mItem = "GT,xy"

def getSeq(self):

return [self.mID,self.mTimeStamp,self.mDuration,self.mParentTask,

self.mSubTask,self.mPriority,self.mItem]

s1 = stepF()

s1.ID=1

s2 = stepF()

data.append(s1.getSeq())

data.append(s2.getSeq())

writer.writerows(data)

csvfile.close()

读CSV格式的实例如下，这个init函数是用来在读入的时候构建实例：

#!/usr/bin/env python

# -*- coding: UTF-8 -*-

import csv

from datetime import *

class stepF:

mID = 0

mTimeStamp = datetime(1990,5,11,8,8,8)

mDuration = 0

mParentTask = 0

mSubTask = 1

mPriority = 0

mItem = "GT,xy"

def __init__(self,all):

self.mID,self.mTimeStamp,self.mDuration,self.mParentTask,self.mSubTask,self.mPriority,self.mItem=all

def getSeq(self):

return [self.mID,self.mTimeStamp,self.mDuration,self.mParentTask,

self.mSubTask,self.mPriority,self.mItem]

csvfile = file('ss.txt','r')

reader = csv.reader(csvfile)

n = 0

data = []

for line in reader:

if n ==0:

n=1

continue

s = stepF(line)

print(s.mItem)

data.append(s)

csvfile.close()

print(data[1].mTimeStamp)

2.3 根据时间对ID排序。可以采用冒泡排序法，如下：

def sortSteps(data):

for i in range(len(data)):

for j in range(len(data)-1,i,-1):

if data[j].mTimeStamp < data[j-1].mTimeStamp:

temp = data[j]

data[j] = data[j-1]

data[j-1]=temp

2.4 线程模块如下，主要是实现了多个task并行执行

def delayrun(delayTime, delayMessage):

root = Tk()

root.title("remind")

root.geometry('500x600')

root.resizable(width=False,height=True)

s = delayMessage

l = Label(root, text=s, bg="green", font=("Arial",24),width=200, height=600)

time.sleep(delayTime)

l.pack()

root.mainloop()

class tkThread(threading.Thread):

def __init__(self, delayTime,delayMessage):

threading.Thread.__init__(self)

self.delayTime =delayTime

self.delayMessage =delayMessage

def run(self):

delayrun(self.delayTime,self.delayMessage)

3.最后把各个模块组合起来实现了读入csv文件并定时显示事件，需要注意的是csv第一行是标题不能占用。ss.txt格式如下：

ID,TimeStamp,Duration,ParentTask,SubTask,Priority,Item

0,2016-06-13 22:00:08,0,0,1,0,"详细规划"

3.1 全部代码如下:

#!/usr/bin/env python

# -*- coding: UTF-8 -*-

import csv

from datetime import *

from Tkinter import *

import threading

import time

'''定义这个变量用来方便写入读出csv文件'''

class stepF:

mID = 0

mTimeStamp = datetime(1990,5,11,8,8,8)

mDuration = 0

mParentTask = 0

mRepeated = 1

mPriority = 0

mItem = "GT,xy"

def __init__(self,all):

self.mID,self.mTimeStamp,self.mDuration,self.mParentTask,self.mRepeated,self.mPriority,self.mItem=all

def getSeq(self):

return [self.mID,self.mTimeStamp,self.mDuration,self.mParentTask,

self.mRepeated,self.mPriority,self.mItem]

'''对事件变量进行排序，主要是针对时间点来排序'''

def sortSteps(data):

for i in range(len(data)):

for j in range(len(data)-1,i,-1):

if data[j].mTimeStamp < data[j-1].mTimeStamp:

temp = data[j]

data[j] = data[j-1]

data[j-1]=temp

'''输出到文件中去'''

def outputData(data):

csvfile = file('ss.txt','w')

writer = csv.writer(csvfile)

writer.writerow(['ID','TimeStamp','Duration','ParentTask'

,'SubTask','Priority','Item'])

for i in range(len(data)):

data[i].mID = i

writer.writerow(data[i].getSeq())

csvfile.close()

''' 读入数据'''

def inputData(data):

csvfile = file('ss.txt','r')

reader = csv.reader(csvfile)

n = 0

for line in reader:

if n ==0:

n=1

continue

s = stepF(line)

data.append(s)

csvfile.close()

''' 在屏幕上显示提示信息'''

def delayrun(delayTime, delayMessage):

root = Tk()

root.title("remind")

root.geometry('500x600')

root.resizable(width=False,height=True)

s = delayMessage

l = Label(root, text=s, bg="green", font=("Arial",24),width=200, height=600)

time.sleep(delayTime)

l.pack()

root.mainloop()

''' thread用来显示多个事件'''

class tkThread(threading.Thread):

def __init__(self, delayTime,delayMessage):

threading.Thread.__init__(self)

self.delayTime =delayTime

self.delayMessage =delayMessage

def run(self):

delayrun(self.delayTime,self.delayMessage)

''' 用来存储读入的事件'''

data = []

inputData(data)

sortSteps(data)

''' 运行多个线程，当时间到了以后显示tk信息'''

for i in range(len(data)):

dt = datetime.today()

nt = datetime.strptime(data[i].mTimeStamp,"%Y-%m-%d %H:%M:%S")

if dt> nt:

continue

print(str(i))

print(str((nt-dt).total_seconds()))

print(data[i].mItem)

t=tkThread((nt-dt).total_seconds(),data[i].mItem)

t.start()

print("wait or not")

'''outputData(data)'''
