Python 图形程序入门
课程概要：
1、wxPython 介绍与安装
2、基本控件介绍与绝对布局
3、控件相对布局
4、多线程与事件
一、wxPython 介绍与安装
◆ wxPython 介绍
◆ wxPython VS PyQt
◆ wxPython 安装
wxPython 介绍
◆ wxPython 是wxWidgets在Python语言下的封装.
◆ wxWidgets是一个跨平台的GUI应用编程接口，使用C++编写。
◆ 所想即所得，缺乏成熟的IDE.
◆ 图形界面风格与系统的风格相似。wxPython VS PyQt
为什么选择wxPython而不是pyQt?
◆ 协议
◆ 编码风格
◆ 复杂性
◆ 个人习惯wxPython 安装
◆ 官方网站：http://www.wxpython.org/
◆ 下载链接：http://www.wxpython.org/download.php#msw/
◆ 安装程序自动寻找Python的位置，基本一路下一步
注：python(x, y)已经包含了wxPython

二、基本控件介绍与绝对布局
◆ 基本控件介绍
◆ 绝对布局
基本控件介绍
静态文本:wx.StaticText
文本域:wx.TextCtrl
按钮:wx.Button
单选与复选按钮：wx.CheckBox/wx.RadioButton
列表框：wx.ListBox
图片：wx.StaticBitmap绝对布局
◆ 基于控件的坐标摆放空间
◆ 简单直观
◆ 方法单一
◆ 不能随窗口的改变而调整位置
相关代码：绝对布局（cx1_2_1.py）

四、多线程与事件
◆ Python 多线程
◆ 控件的事件
1) Python 多线程
a) 不使用多线程可能会导致图形界面卡死
b) 多线程可以使程序以更高的效率运行
c) 多线程可以让程序做更多的事情
d) thread.start_new_thread(函数名，(参数1，参数2，…))
e) 使用Threading模块创建线程（不讲）
2) 控件的事件
a) 按钮点击
b) 文本域内容改变
c) 鼠标滑过
d) 键盘按下
