Can not reorder QObject children

Peter Harvey

Hi, I am deriving in-app data from QObject so I can take advantage stuff like RTTI, parent/child relationship, etc. But I need to have non-const access to a QObjects child list - primarily to change the position of a child object in the list (similar to what QWidget does). Any thoughts on how I can do this?

To reorder children, you can:

Get all children list;
Set parent to null one by one;
Reorder them;
Set parent to original parent one by one.

Hi and welcome to devnet,

Out of curiosity, why do you need to fiddle with the order of the children of a QObject object ?

@SGaist basically for the same reason as QWidget - to maintain a Z-Order.

@jiancaiyang interesting - this may work :)
