How to keep a widget after its parent widget death?

[wysota]

child->setParent(0);

child->setParent(0);

To copy to clipboard, switch view to plain text mode

Hi, wysota,

I didn't use setParent, and it works.

groupBoxList_dataFormat->at(i)->setLayout(binaryDataFormatUI->at(i)->layout);

groupBoxList_dataFormat->at(i)->setLayout(binaryDataFormatUI->at(i)->layout);

To copy to clipboard, switch view to plain text mode 

Maybe it besause binaryDataFormatUI->at(i)->layout is not declared with setting groupBoxList_dataFormat->at(i) as parent.

If you move a layout to another widget (if that's possible) then the widgets in a layout get reparented to the new widget.
