more explanation of QQuickItem::windowChanged(..)

Hello forum,

I am going through the documentaion - "Scene Graph - OpenGL Under QML" and there is a signal/slot connection as follows:

Code:

---

connect(this, SIGNAL(windowChanged(QQuickWindow*)), this, SLOT(handleWindowChanged(QQuickWindow*)));

---

I have seen in the documentation about the signal -

Code:

---

windowChanged(QQuickWindow*)

---

it says that the signal is emitted when the item's window changed. What kind of changes are we talking about here - window creation, resizing, dragging, mouse/key focus ?

Any one to put more light into this ?

Thanks

From the documentation my guess is that it works like property change signal, i.e. it is emitted when the pointer returned by QQuickItem::window() changes.

So when the item gets first added to a scene of a QQuickWindow or when it is moved to a scene of a different window.

Cheers,
