我認(rèn)為您的意思是您成功將此代碼添加到主窗口，但您希望能夠?qū)⑵涮砑拥侥谠O(shè)計器中制作的小部件中，而不是嚴(yán)格意義上的主窗口。
如果是這種情況，您想要做的是在 Qt Designer 中按照您想要的方式格式化您的小部件，在您想要插入 Display_Pixels QGraphicsView 對象的位置添加一個占位符，例如框架、布局、可能是一個組等。
之后不會直接將其添加到框架中，而是將該框架使用的任何布局。所以如果你的框架中有一個網(wǎng)格布局，它會是這樣的：
self.Disp_pixel = Display_Pixels()
widget_name.gridlayout.addWidget(self.Disp_pixel)
很難告訴您這段代碼將在您的代碼中的何處實現(xiàn)，但假設(shè)您運行了 pyuic5 并獲得了 python 輸出。您可以將它添加到該輸出 python 文件中。我建議使用類似查看器類的東西，它繼承生成的輸出類并在其中執(zhí)行添加小部件。此外，frame 將是您為圖形視圖創(chuàng)建的框架的名稱，而不是字面上的框架。
此外，我不確定您是否可以在任何類型的小部件上進(jìn)行展示，我很確定小部件必須是可顯示的，例如主窗口小部件或?qū)υ捒蛐〔考?。也就是說小部件可以放置在其他小部件中。
這是我給你的一個例子，它有點粗糙，但我認(rèn)為它會有所幫助：
