【问题描述】：

所以我已经使用 pyuic 和 pyrcc 将我的 QT Design 和 QRC 文件转换为 python。 当我导入 QRC 的 python 文件时，它一直说它在代码中未使用。 我猜没有正确使用它，但在任何地方都找不到答案。 如果有人能帮助我理解并正确使用它，我将不胜感激。

【问题讨论】：

你在哪里导入文件？请提供minimal reproducible example。另请注意，您没有翻译为python：您将 UI和QRC转换为 python；翻译是关于口语和本地化的。

在同一个python文件中

@musicamante 添加了更多代码

背景图像值的格式应为url(path):background-image: url(:/image/LogoAndText.png);。

我已将其更改为 = self.Background.setStyleSheet("background-image: url(:/image/LogoAndText.png);\n" "background-repeat: repeat-x;")但它仍然无法正常工作，我收到同样的警告，即导入的 backgroundImage 仍未使用

【参考方案1】：

QRC 文件的转换必须在主脚本中导入，而不是转换后的 UI 文件！谢谢@musicamante！
