Unsolved How do I add a qtablewidget in a qscrollarea to make it scrollable?

[CEO.]

Hello great minds,

Please how do I add my qTableWidgets scrollable in a qScrollArea?
I want the qTableWidgets to be in the scrollarea but from the codes below, whenever I add the qTablewidget to the vbox1 layout, nothing displays on the window when I run the code.

<>
        glayttab = QGridLayout()
        gboxtab = QGroupBox()
        gboxtab.setCheckable(True)
        vboxtab1 = QVBoxLayout()
        self.setLayout(glayttab)
        glayttab.addWidget(gboxtab)
        gboxtab.setLayout(vboxtab1)
        self.tab = QtWidgets.QTableWidget(self)

         vboxtab1.addWidget(self.tab)
         
        scroltab = QScrollArea()
         
        scroltab.setHorizontalScrollBarPolicy(Qt.ScrollBarAlwaysOn)
         
        scroltab.setVerticalScrollBarPolicy(Qt.ScrollBarAlwaysOn)
         
        scroltab.setWidgetResizable(True)
         
        scroltab.setWidget(gboxtab)
         
        scroltab.ensureVisible(1900, 1900)
         
        glayttab.addWidget(scroltab)`

QTableWidget is a scroll area (the inheritance graph is QAbstractScrollArea→QAbstractItemView→QTableView→QTableWidget) so you don't need to insert it in a scroll area.
What is the result you are trying to get?

Thanks for your feedback.
I see where I was making the mistake. I was using QMainWindow for the class, and didn't setCentral area. I have to change my class to QWidget. It works fine now
