簡述

我覺得一個好看的 UI 可以潛意識地激勵我們，不僅可以讓我們工作的更高效、更有樂趣，而且可以讓應用程式變得更漂亮、更直觀。

我比較喜歡風格一致的產品，讓所有的東西看起來像是一個大家庭，給人一種專業的視覺享受。當做出很專業的產品時，你甚至可以很自豪地稱自己為一個藝術家。

故事情節

首先，感謝 Yasin，為我們提供了一套很經典的 QSS 樣式 - Qt dark orange stylesheet 。暗橙色（橙色 + 深灰色）的配色和 

在文章開頭的時候，作者寫道：

When I started with Qt I looked for a good looking stylesheet out there but I couldn’t find a single one, seems like people doesn’t like to share their styles. 
當我開始使用 Qt，想要尋找一個好看的樣式表，但卻找不到，人們似乎不喜歡分享他們的樣式風格。

這是一個很有趣的現象，值得思考！

開源，是一種精神。。。分享，是一種態度。。。 
共享知識，分享成長！

再次感謝作者。。。

PS：真想對作者說快來參考我的部落格，你要的樣式統統都有O(∩_∩)O哈哈~
