PyQt5简介及demo

發布時間：2025/7/14 编程问答 24 豆豆

生活随笔收集整理的這篇文章主要介紹了 PyQt5简介及demo 小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

PyQt5說明

　　pyqt5是一套Python綁定Digia QT5應用的框架。它可用于Python 2和3。本教程使用Python 3。Qt庫是最強大的GUI庫之一。pyqt5的官方網站http://www.riverbankcomputing.co.uk/news。

　　pyqt5做為Python的一個模塊，它有620多個類和6000個函數和方法。這是一個跨平臺的工具包，它可以運行在所有主要的操作系統，包括UNIX，Windows，Mac OS。pyqt5是雙重許可。開發者可以在GPL和商業許可之間進行選擇。

　　pyqt5的類別分為幾個模塊，包括以下：

QtCore：包含了核心的非GUI功能。此模塊用于處理時間、文件和目錄、各種數據類型、流、URL、MIME類型、線程或進程。
QtGui：包含類窗口系統集成、事件處理、二維圖形、基本成像、字體和文本。
QtWidgets：包含創造經典桌面風格的用戶界面提供了一套UI元素的類。
QtMultimedia：包含的類來處理多媒體內容和API來訪問相機和收音機的功能。
QtBluetooth：包含類的掃描設備和連接并與他們互動。描述模塊包含了網絡編程的類。這些類便于TCP和IP和UDP客戶端和服務器的編碼，使網絡編程更容易和更便攜。
QtNetwork
QtPositioning：包含類的利用各種可能的來源，確定位置，包括衛星、Wi-Fi、或一個文本文件。
Enginio：模塊實現了客戶端庫訪問Qt云服務托管的應用程序運行時。
QtWebSockets：包含實現WebSocket協議類。
QtWebKit：包含一個基于Webkit2圖書館Web瀏覽器實現類。
QtWebKitWidgets：包含的類的基礎webkit1一用于qtwidgets應用Web瀏覽器的實現。
QtXml：包含與XML文件的類。這個模塊為SAX和DOM API提供了實現。
QtSvg：提供了顯示SVG文件內容的類。可伸縮矢量圖形（SVG）是一種描述二維圖形和圖形應用的語言。
QtSql：提供操作數據庫的類。
QtTest：包含測試的功能，使pyqt5應用程序的單元測試

PyQt4和PyQt5的區別

　　pyqt5不向后兼容pyqt4。pyqt5有幾個顯著的變化。將舊代碼調整到新庫并不困難。有幾個大的改變如下：

- Python模塊已經重組。一些模塊已經刪除（qtscript），有的被分割成子模塊（QtGui，QtWebKit）。
- 新的模塊作了詳細的介紹，包括qtbluetooth，qtpositioning，或enginio。
- pyqt5只支持新型的信號和槽handlig。電話signal()或slot()不再支持。
- pyqt5不支持Qt的API被標記為過時或陳舊的任何部分在QT V5.0。

Demo

　　本人曾寫過一個數字貨幣搬磚的界面，效果如下圖：

　　界面的設計用的是pyqt5，設計完成后使用命令??python -m PyQt5.uic.pyuic xxx.ui -o xxx.py? 轉換為python的代碼

轉換后的代碼：
