天天向上

下面為一個簡單UI設計
1. 利用Claude，透過它快速得到一個漂亮的範例(python程式碼)
2. 利用Claude，抽取python程式碼中GUI相關程式碼並輸出成Qt Designer可以編輯ui格式

1. 利用Designer設計一個人機介面，存成檔案 yolo_setting.ui

加入一個繼承Object的新類別Test，

This time we are going to create a new Object intead of using subclass of QThread,and all its job is transfer to a QThread instance by calling moveToThread method.You can find out details on youtube.
Let’s create a new project of window application and add new class, in which it accumaltes from 1 to 999.
