用Python 写一个日程表

用Python 写一个日程表

依赖: urwid;

1 基本框架

main.py

import urwid

def exit_on_q(key):
    if key in ('q', 'Q'):
        raise urwid.ExitMainLoop()

palette = [
    ('banner', 'black', 'light gray'),
    ('streak', 'black', 'dark red'),
    ('bg', 'black', 'dark blue'),]

txt = urwid.Text(('banner', u" Hello World "), align='center')
map1 = urwid.AttrMap(txt, 'streak')
fill = urwid.Filler(map1)
map2 = urwid.AttrMap(fill, 'bg')
loop = urwid.MainLoop(map2, palette, unhandled_input=exit_on_q)
loop.run()

ToDolist

文本文件, 用tab分隔

语文  10  0
数学  10  0
英语  10  0

2 读取内容从ToDolist

加入下文的第一行, 并在上文的12行, 改成下文第二行

TODO = open(sys.path[0]+"/ToDolist",'r').read()
txt = urwid.Text(('banner', TODO), align='center')

当然, 这不是想要效果, 2333. 最好的是用numpy或者pandas来读成表格, matrix 的数据结构, 但是我不想为这么点点东西来费这么大的力气, 所以我就全用list了.

def Read_ToDolsit():
    TODO = open(sys.path[0]+"/ToDolist",'r').read().split('\n')[:-1]
    Result = []
    for i in TODO:
        Result += [i.split()]
    return Result

这样, 之前的 open, 就直接改成

TODO = Read_ToDolsit()

输出的TODO变成了:

[['语文', '10', '0'], ['数学', '10', '0'], ['英语', '10', '0']]

3 放入列表

写一个循环读取, 并放入columns, columns 叠入Pile

def TODO_col(TODO):
    Column_list = []
    for Sub in TODO:
        Sub_list = []
        for i in Sub:
            Sub_list += [urwid.Text(i)]
        Column_list += [urwid.Columns(Sub_list)]
    A = urwid.Pile(Column_list)
    return A

这样的话, 自动读取结果就是:

增加修改按钮:

如何做到按钮对应每一列的操作, 我想的解决方案是,按钮直接操作ToDolist, 然后刷新整个页面. 反正都是小文本, 整个过程都是毫秒级的.

4 添加计数按钮

想了好久= = 么有好方法= =只好预写一堆的button signal 放在 另一个页面, 然后丢在list里面 调用= = 唉, 虽然蠢, 但是有效就好.


不管怎么样- - 反正, 我算是成功了- - 唉… 虽然代码很丑

5 将数字改成长条

我们把按钮左移, 然后加一个10个单位的进度条, 底色为红色

def Bar_line(Sub,Bar_Max=20):
    if int(Sub[2])<= int(Sub[1]):
        Bar_G = int(int(Sub[2])*Bar_Max/int(Sub[1]))
        Bar_R = Bar_Max - Bar_G
        Bar_B = 0
    elif int(Sub[2]) > int(Sub[1]):
        Bar_G = Bar_Max-1
        Bar_R = 1
        Bar_B = int((int(Sub[2])-int(Sub[1]))*Bar_Max/int(Sub[1]))
        #print(int((int(Sub[2])-int(Sub[1]))*Bar_Max/int(Sub[1])))
    Sub_bar  = [('fixed',40,urwid.Text([('Green_BG', " "* Bar_G),('Red_BG', " "*Bar_R),('Blue_BG', " "*Bar_B)]))]
    return Sub_bar

到此, 最简单的日程表, 就已经做好啦!

def Button_C():
    def Clean(botton):
        List = Read_ToDolsit()
        for i in List:
            i[2] = str(0)
        Str_list = List2str(List)
        F = open(sys.path[0]+"/ToDolist",'w')
        F.write(Str_list)
        F.close()
        # refresh
        loop.widget = Setupview()
    Button_clean = urwid.Button(u"Clear")
    urwid.connect_signal(Button_clean, 'click', Clean)
    return Button_clean

Setview改一下:

def Setupview():
    Header = BigTxt("What's Next???")
    TODO = Read_ToDolsit()
    ToDOcol_list = TODO_col(TODO)
    Button_clean = Button_C()
    ToDoWidget = urwid.Pile([Header] + ToDOcol_list+[Button_clean])
    fill = urwid.Filler(ToDoWidget)
    return fill
