This part from your snippet isn't correct, for multiple reasons:
self.setTabButton(
0,
QtGui.QTabBar.ButtonPosition.RightSide,
self.add_button
)
hlay = QtGui.QHBoxLayout()
hlay.addWidget(self.add_button)
hlay.addWidget(self)
As documented, setTabButton will take ownership of the button. But then you
add it to a layout. Just create it without a parent and pass it
to setTabButton.
Also, the new layout is created but not attached to to manage any widget.
You add the button and then self and then the layout does nothing.
Just get rid of the layout, is my best guess.
