How to Create child widget behind parent widget?

[anupamgee]

hi all,
I want to create a child widget behind parent widget .How to do this.

[wysota]

You can't. The child is always on top of its parent. You can only mix sibling widgets. But what is your usecase? It's very unlikely that you do need to place one widget behind the other.

thanx for reply
Can u explain how i can place siblings behind one another.I tried stackUnder(QWidget *);

[wysota]

This is not something you can really control and I would advise against trying and instead tell us what you are trying to do and we will think of a better solution.

hi wysota and all,

is it the standard behavior of Qt that the parent widget will be displayed always below the child, if they are overlapped?

In my app, i have a control bar widget which is the parent to all other widgets. When the control bar overlapped with any other widget it is being displayed under that widget. But I need to display the control bar on top of children if its clicked and children on top if they are clicked.

How that can be achieved?

Thanks in advance!

Child widget is always on top of its parent and can't extend past the area occupied by its parent (so they always "overlap").

in my case both widgets are window and normally they don't overlap unless you put one over another.
i have made the "control bar" parent by calling setParent(this, Qt::Window) on it.

how can i make the z-order normal so that the control bar (parent) will not stay always behind the child widget?

edit:
I got the answer here.
