如何在Ubuntu系统下使用Python的GUI工具wxPython？

#使用：apt-cache search wxpython 测试一下，可以看到相关信息
dizzy@dizzy-pc:~/Python$ apt-cache search wxpython

#这样的话，直接使用： sudo apt-get install python-wxtools 即可安装

#做过桌面软件开发的，对这个肯定很熟悉。
#由于之前学过一点VB，VC，Delphi等，学起来感觉很简单。
#将wx提供的控件添加到某个Frame上，并进行各自的属性设置即可完成
#由于文本控件的size属性，设置的为绝对值。这样就会有一些问题......

## 当然，之前说将各种控件的位置都写成绝对位置和大小，会有一些问题。这是不对的
## 有时需要动态布局，而有时则需要静态布局
