qt绘制倾斜带间隔的进度条
求助大佬们，这种怎么在painting里面绘制啊，用qpainter绘制，qprogressbar的qss不支持倾斜绘制 本帖最后由 yanlusu 于 2024-6-19 20:31 编辑import sys

chatgpt：
Use qt6 to customize a progress bar. In the progress bar, multiple color blocks tilted at 30 degrees are used to indicate the progress. Each color block represents 1%. The width of the color block is 6 pixels, and the distance between the color blocks is 3 pixels.
非常的牛叉的效果哦 一楼的是借用了一下ChatGPT吗？ 学习一下，后面也会学到qt yanlusu 发表于 2024-6-19 20:29

学习一下，打算写个cpp版本的 swico 发表于 2024-6-20 11:49

直接chatgpt，让它用c++转一下就可以。
