python3+PyQt5实现窗口切分条
本文是对《Python Qt GUI快速编程》的第9章的窗口切分条例子News Reader 用Python3+PyQt5进行改写。
注：import qrc_resources，资源文件resources.qrc如下：
===========================
<RCC version="1.0">

is now available.
The new binaries are available for download from the groups page :
Movable Python Groups Page
http://voidspace.tradebit.com/groups.php
Binaries are uploaded for Python 2.2.3, 2.3.5, 2.4.4, 2.5 and the
MegaPack
http://www.voidspace.org.uk/python/movpy/megapack.html.
There is also a fresh version of the free demo, based on Python 2.3.5:

What is Movable Python
Movable Python is a distribution of Python, for Windows,
that can run without being installed. It means you can carry a full
development environment round on a USB stick.
It is also useful for testing programs with a 'clean Python install',
and testing programs with multiple versions of Python.
The GUI program launcher makes it a useful programmers tool, including
features like :
- Log the output of all Python scripts run
- Enable Psyco for all scripts
- Quick Launch buttons for commonly used programs
- Configure multiple interpreters for use from a single interface
It comes with the Pythonwin IDE and works fine with other IDEs like
SPE
http://developer.berlios.de/projects/python/.
Plus many other features and bundled libraries."""
