        sorry for a long delay ,
        this ui is created by myself
        I am calling this ui in one function funcn()
        funcn()
        {
        QFile file(":/forms/selectiondialog.ui");
        QWidget *selectionWidget = this->loadUiFile(file);
        }

        QWidget* OptimaRTools::loadUiFile(QFile& file1)
        {

        QUiLoader loader;
         QFile file(":/forms/selectiondialog.ui");
        file.open(QFile::ReadOnly);
        file.errorString();
        QWidget *formWidget = loader.load(&file);
        file.close();
        

        return formWidget;
        }

        and the ui file is

        <?xml version="1.0" encoding="UTF-8"?>

          Please use coding tags

          What do you mean by yourself ? Using the designer integrated with QtCreator ?

                What does print:

                @qDebug() << file.readAll();@

                ?

                    Really strange...

                    Could you try to run the Calculator builder example ? To see if it also has the same problem

                        Then copy the ui file from the example in your project and try to load to see if it works also there

                              Then can you post your pro file and a minimal code example that reproduce the problem ?
