日程处理

1. 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)'''
