開(kāi)智學(xué)院的第二周任務(wù)，把CLI下的日記寫成窗口的形式表現(xiàn)出來(lái)，基本實(shí)現(xiàn)的功能如下：
- 每次輸入一行
- 輸入前把上次內(nèi)容打印出來(lái)
- 自動(dòng)保存在工作路徑
把CLI在窗口中表現(xiàn)出來(lái)议薪，開(kāi)智學(xué)院提示用到Tkinter，常用的官方文檔如下：
- An Introduction To Tkinter這個(gè)是我看的最多的，解釋的很詳盡基本能解決大媽留下來(lái)的問(wèn)題是迁霎，下面兩個(gè)也是芝麻星上給出的
- Tkinter reference: a GUI for Python
- 24.1. Tkinter — Python interface to Tcl/Tk
開(kāi)始學(xué)習(xí)使用Tkinter( 我的運(yùn)行環(huán)境是Win7 Sublime text 3 Powershll)

我的代碼用的基本組件
- Label
- Entry
- Frame
- Button
-
組件方法
- .insert
- .delete
下面是我的全部代碼

- 重要細(xì)節(jié)總結(jié)
- 代碼分三大塊
1.Button區(qū)域用了frm框起來(lái)
2.中間的文本顯示區(qū)直接關(guān)聯(lián)root
3.Label和Entry組件從屬于frm2 - frm,frm2和T都從屬于root
- 每個(gè)組件按要求寫完后都要寫完相應(yīng)的.pack()
- 代碼分三大塊
