PyQt 4.8.4 发布，Qt 库的 Python 绑定
Support was added for Qt v4.7.2. QObject.findChild() and QObject.findChildren() now allow a tuple of type objects as well as a single type argument so that children of a number of types may be found. Support for QCommonStyle was added. Limited support for setEventFilter() and filterEvent() was added to QAbstractEventDispatcher. Support for setAttributeArray() was added to QGLShaderProgram. pyrcc4 will now compress by default to match the behavior of rcc. QTouchEventSequence was removed, as its C++ API makes it impossible to be used from Python.
PyQt是Qt库的Python版本。PyQt3支持Qt1到Qt3。 PyQt4支持Qt4。它的首次发布也是在1998年，但是当时它叫 PyKDE，因为开始的时候SIP和PyQt没有分开。PyQt是用SIP写的。PyQt遵从奇趣的许可模式，有GPL版和商业版。
