PyQt5 StackedWidget第一页边框图像不起作用

Question

我正在使用带有PyQt5的堆叠式小部件来实现菜单页面和子菜单页面，并且我试图设置一个欢迎页面，一旦您运行该应用程序并在3秒钟后切换到主菜单页面，该页面就会显示。 我遇到的问题是，当我将.ui文件转换为.py文件并执行脚本时，除欢迎页面边框图像（未显示）之外，所有页面边框图像都工作正常。

请注意，我正在使用Qt Designer

这是错误...这是欢迎页面未显示边框图像：

其他页面工作正常，其他页面（显示其边框图像）： 谢谢

代码：

Answer 1

我尝试了您的代码，它对我有用。

您应检查的内容：

• 文件路径是否正确:/img/img/main menu.png ？
• 尝试将映像放在磁盘上，然后重试
• 尝试使用简单的名称（例如D:/im.png将映像放在磁盘上
• 尝试使用已在另一页面上使用的图像
• 检查您的资源文件是否已编译（您可以在Qt Creator的编译器日志中找到对rcc.exe的调用）。

从Qt的角度来看，它看起来不错。

真是令人困惑，但它正在工作！ 我刚刚再次转换了.qrc文件，它现在运行良好
