Attempting to set QLayout "layout1" on QFrame "frame1", when the QLayout already has a parent

[marius63]

I'm getting the above error upon

@
frame1->setLayout(layout1);
@

Do I need to unparent layout1, make it an orphan? How?
Thanks.

/*
I could not find a reference or discussion on this.
There's enough reference and discussion on the similar issue of when the widget (frame1) already has a layout.
That's not the case here.
"frame1" is empty, has no children, no layout.
The problem here is that "layout1" is already set onto some other widget (parent?)

This warning is given if the parent of that layout is not a widget.

Reparenting with setParent might work:
@layout1->setParent(0);
frame1->setLayout(layout1);@
