python3+PyQt5泛型委托詳解

更新時間：2018年04月24日 08:33:41 作者：basisworker

這篇文章主要為大家詳細介紹了python3+PyQt5泛型委托的相關資料，具有一定的參考價值，感興趣的小伙伴們可以參考一下

自定義委托可以讓我們對視圖中出現(xiàn)的數(shù)據(jù)項的外觀和行為進行完全控制。如果有很多模型，可能會希望不是全部的大多數(shù)模型能夠僅用一個自定義委托，如果不能這么做，那么對于這些自定義委托，將很有可能存在大量重復代碼。為了使得維護工作變得輕松，更好的方法為不要為每個模型創(chuàng)建一個自定義委托，而是用一系列的通用組件來共同構成一個委托。本文通過Python3+pyqt5實現(xiàn)了python Qt GUI 快速編程的16章的泛型委托例子。
