     The most common way to use QGraphicsGridLayout is to construct an object
-    on the heap with no parent, add widgets and layouts by calling addItem(),
-    and finally assign the layout to a widget by calling
-    QGraphicsWidget::setLayout(). QGraphicsGridLayout automatically computes
+    on the heap, passing a parent widget to the constructor, then add widgets
+    and layouts by calling addItem(). QGraphicsGridLayout automatically computes
     the dimensions of the grid as you add items.

+    Alternatively, if you do not pass a parent widget to the layout's constructor,
+    you will need to call QGraphicsWidget::setLayout() to set this layout as the
+    top-level layout for that widget, the widget will take ownership of the layout.
+
     The layout takes ownership of the items. In some cases when the layout
     item also inherits from QGraphicsItem (such as QGraphicsWidget) there will be a
     ambiguity in ownership because the layout item belongs to two ownership hierarchies.
