PyQt5: nested layouts

[Rodrigo de Salvo Braz]

Hi Rich,

The problem occurs at line

row1 = qtw.QHBoxLayout(self)

When you create a layout with a QWidget argument (here, self), you are
saying that this will be the layout for that widget. However, you had
already done the same for the inner layout:

inner = qtw.QVBoxLayout(self)

so self already had a layout.

To fix it, you simply need to create row1 without the argument self:

row1 = qtw.QHBoxLayout(self)  # no argument

Hope that helps.

Rodrigo
