StackedWidget will not accept a custom QWidget with addWidget

[mortem]

Hello,
I might be missing something crucial here. I'm trying to create multiple "views" with StackedWidget by putting my custom QWidget class inside that StackedWidget. Now I created a new class called SearchView which is supposed to go in the StackedWidget as one of the "views". The problem is that StackedWidget->addWidget will not accept it even though this SearchView is inherited from QWidget (I created the SearchWidget with Qt designer form class from QTCreator). Am I not supposed to do this? If I have missed a relevant tutorial or page I am very sorry but I could not find an answer to this problem. Thank you for your time

MainWindow::MainWindow(QWidget *parent)
    : QMainWindow(parent)
    , ui(new Ui::MainWindow)
{
    ui->setupUi(this);

    Ui::SearchView *search_view = new Ui::SearchView();
    ui->stackedWidget->addWidget(search_view);

searchview.h looks like this

namespace Ui {
class SearchView;
}

class SearchView : public QWidget
{
    Q_OBJECT

public:
    explicit SearchView(QWidget *parent = nullptr);
    ~SearchView();

private:
    Ui::SearchView *ui;
    void populateTable(QTableWidget *table);
};

The error in question is:
mainwindow.cpp:12:34: Cannot initialize a parameter of type 'QWidget *' with an lvalue of type 'Ui::SearchView *'
qstackedwidget.h:62:28: passing argument to parameter 'w' here

You want 'SearchView', not the uic generated class 'Ui::SearchView'
