我整理了一个自定义QGraphicsView，我可以在Python的主窗口中显示它，但我很难将它集成到我用Qt Designer制作的表单中。我如何将其添加到表单中？
另外，我还添加了一个mousepress事件。如何使用Qt Designer制作的表单将其集成到app中？我使用Qt Designer构建了一个完整的应用程序，其他一切都可以工作，我只需要能够将这个部分与其余部分一起添加。

我认为您的说法是成功将此代码添加到主窗口，但您希望能够将其添加到您在设计器中创建的小部件中，而不是严格地将其添加到主窗口中。
如果是这样的话，你想要做的就是在Qt Designer中按照你想要的方式添加一个占位符，例如框架，布局，可能是一个组等，你想插入你的Display_Pixels QGraphicsView对象。
之后不会直接将其添加到框架中，而是将框架正在使用的任何布局。所以，如果你的框架中有一个gridlayout，它将是这样的：
self.Disp_pixel = Display_Pixels()
widget_name.gridlayout.addWidget(self.Disp_pixel)
很难告诉你代码在代码中的实现位置，但假设你说你运行了pyuic5并获得了python输出。您可以将其添加到输出python文件中。我建议让像查看器类继承生成的输出类并在那里执行添加小部件。框架也是您为图形视图创建的框架的名称，而不是字面框架。
此外，我不确定你是否可以在任何类型的小部件上进行演出我非常确定小部件必须是可显示的，例如主窗口小部件或对话框小部件。也就是说，小部件可以放在其他小部件中。
这是我给你的一个例子，它有点粗糙，但我认为它会有所帮助：
