PyQt5 StackedWidget第一頁邊框圖像不起作用

Question

我正在使用帶有PyQt5的堆疊式小部件來實現菜單頁面和子菜單頁面，並且我試圖設置一個歡迎頁面，一旦您運行該應用程序並在3秒鍾后切換到主菜單頁面，該頁面就會顯示。 我遇到的問題是，當我將.ui文件轉換為.py文件並執行腳本時，除歡迎頁面邊框圖像（未顯示）之外，所有頁面邊框圖像都工作正常。

請注意，我正在使用Qt Designer

這是錯誤...這是歡迎頁面未顯示邊框圖像：

其他頁面工作正常，其他頁面（顯示其邊框圖像）： 謝謝

Answer 1

我嘗試了您的代碼，它對我有用。

您應檢查的內容：

• 文件路徑是否正確:/img/img/main menu.png ？
• 嘗試將映像放在磁盤上，然后重試
• 嘗試使用簡單的名稱（例如D:/im.png將映像放在磁盤上
• 嘗試使用已在另一頁面上使用的圖像
• 檢查您的資源文件是否已編譯（您可以在Qt Creator的編譯器日志中找到對rcc.exe的調用）。

從Qt的角度來看，它看起來不錯。

真是令人困惑，但它正在工作！ 我剛剛再次轉換了.qrc文件，它現在運行良好
