Hello forum,

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

Qt Code: 
  1. connect(this, SIGNAL(windowChanged(QQuickWindow*)), this, SLOT(handleWindowChanged(QQuickWindow*)));
To copy to clipboard, switch view to plain text mode 

I have seen in the documentation about the signal -
Qt Code: 
  1. windowChanged(QQuickWindow*)
To copy to clipboard, switch view to plain text mode 
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
