python Eric 的使用

        最近使用python过程中，python界面的编程工具GTK-Python，但是界面的美观性不如Qt-Creator中的Qt-Designer，无法实现设计是视图绘制，有点让人失望。
        网上发现有人介绍python Eric IDE,比较好奇，安装上看看吧：
       #yum install eric4
        但是新建的工程无法run,说缺少pyuic4，于是安装上开发包
        #yum install PyQt4-devel
        因为之前我按装了qt4.7类库，所以一切都那么顺其自然，新建了一个对话框，因为python eric 中嵌入了Qt -Designer工具，所以绘制的窗口比较美观，上档次，呵呵，不错，保存untitled.ui文件，关闭designer窗口，回到eric IDE 窗口发现在source视图下多了一个Ui_untitled.py文件：
# -*- coding: utf-8 -*-
# Form implementation generated from reading ui file '/home/fedora11/myPro/eric/untitled.ui'
