qt desiner 是一個GUI設計，他可以包容各種語言，可視化拖動操作，qt代碼就像html

pyqt是Python的一個庫，他可以實現(xiàn)gui設計，也可以把qt代碼轉換為Python代碼。

?qt designer去官網下載，用360瀏覽器可以正常下載，火狐瀏覽器不行，估計qt官網采用最新的w3前段技術

，下載是本地網絡不行，用VPN下載 ，中斷率很過，費時間，日本線路有的可以。。。

?他那服務器挺慢，要下載幾個G的東西經?？ㄋ?#xff0c;我之前也像你一樣，所以建議直接下載完整的安裝包

另外一些安裝配置方面的問題可以參看：http://wenku.baidu.com /link?url=MSt8AcsPyVViPlkA6tGweOxV_DBdtiNhZkHA_aOcn4rnY83FwvVzVO26QYMa28gPmMXqykpj2ERQ82u0SQ0oFGhcWeV1a5JbPcaAUfdbUHa

PyQt是一個創(chuàng)建GUI應用程序的工具包。它是Python編程語言和Qt庫的成功融合。Qt庫是目前最強大的庫之一。PyQt是由Phil Thompson 開發(fā)。 PyQt實現(xiàn)了一個Python模塊集。它有超過300類，將近6000個函數(shù)和方法。它是一個多平臺的工具包，可以運行在所有主要操作系統(tǒng)上，包括UNIX，Windows和Mac。 PyQt采用雙許可證，開發(fā)人員可以選擇GPL和商業(yè)許可。在此之前，GPL的版本只能用在Unix上，從PyQt的版本4開始，GPL許可證可用于所有支持的平臺。 因為可用的類有很多，他們被分成幾個模塊。 QtCore模塊包含核心的非GUI功能。該模塊用于時間、文件和目錄、各種數(shù)據(jù)類型、流、網址、MIME類型、線程或進程。QtGui模塊包含圖形組件和相關的類，例如按鈕、窗體、狀態(tài)欄、工具欄、滾動條、位圖、顏色、字體等。QtNetwork模塊包含了網絡編程的類，這些類允許編寫TCP/IP和UDP的客戶端和服務器，他們使網絡編程更簡單，更輕便。QtXml包含使用XML文件的類，這個模塊提供了SAX和DOM API的實現(xiàn)。QtSvg模塊提供顯示的SVG文件的類。可縮放矢量圖形（SVG）是一種用于描述二維圖形和圖形應用程序的XML語言。QtOpenGL模塊使用OpenGL庫渲染3D和2D圖形，該模塊能夠無縫集成Qt的GUI庫和OpenGL庫。QtSql模塊提供用于數(shù)據(jù)庫的類。

What is PyQt?

PyQt is a set of Python v2 and v3 bindings for The Qt Company's Qt application framework and runs on all platforms supported by Qt including Windows, OS X, Linux, iOS and Android. PyQt5 supports Qt v5. PyQt4 supports Qt v4 and will build against Qt v5. The bindings are implemented as a set of Python modules and contain over 1,000 classes.

The Qt Company no longer supports Qt v4. PyQt5 and Qt v5 are strongly recommended for all new development.

PyQt is dual licensed on all supported platforms under the GNU GPL v3 and the Riverbank Commercial License. Unlike Qt, PyQt is not available under the LGPL. You can purchase the commercial version of PyQt here. More information about licensing can be found in the License FAQ.

PyQt does not include a copy of Qt. You must obtain a correctly licensed copy of Qt yourself. However, binary wheels of the GPL version of PyQt5 are provided and these include a copy of the LGPL version of Qt.

PyQt Components

A description of the components of PyQt5 can be found in the PyQt5 Reference Guide.

A description of the components of PyQt4 can be found in the PyQt4 Reference Guide.

Why PyQt?

PyQt brings together the Qt C++ cross-platform application framework and the cross-platform interpreted language Python.

Qt is more than a GUI toolkit. It includes abstractions of network sockets, threads, Unicode, regular expressions, SQL databases, SVG, OpenGL, XML, a fully functional web browser, a help system, a multimedia framework, as well as a rich collection of GUI widgets.

Qt classes employ a signal/slot mechanism for communicating between objects that is type safe but loosely coupled making it easy to create re-usable software components.

Qt also includes Qt Designer, a graphical user interface designer. PyQt is able to generate Python code from Qt Designer. It is also possible to add new GUI controls written in Python to Qt Designer.

Python is a simple but powerful object-orientated language. Its simplicity makes it easy to learn, but its power means that large and complex applications can be created. Its interpreted nature means that Python programmers are very productive because there is no edit/compile/link/run development cycle.

Much of Python's power comes from its comprehensive set of extension modules providing a wide variety of functions including HTTP servers, XML parsers, database access, data compression tools and, of course, graphical user interfaces. Extension modules are usually implemented in either Python, C or C++. Using tools such as SIP it is relatively straight forward to create an extension module that encapsulates an existing C or C++ library. Used in this way, Python can then become the glue to create new applications from established libraries.

PyQt combines all the advantages of Qt and Python. A programmer has all the power of Qt, but is able to exploit it with the simplicity of Python.
