[Qt-qml] completion of Window's re-layouting

[Kauppi Sauli (Nokia-MS/Helsinki)]

I am trying to get information when Window element's children items have 
been relayouted, after orientation change.

Window code needs to signal start and finish of orientation change to 
input method functionality, when VKB (virtual keyboard) is visible. 
Input method functionality takes care of simultaneous rotation animation 
for application window and VKB window. Finish of orientation change 
needs to be signaled, after Window including its application specific 
content has been relayouted.

During orientation change, Window element gets signaled when its area 
changes. But at that time, Window element's children items have not yet 
been relayouted (children items' position, size and anchors are still 
being re-evaluated by declarative engine).

Regards,
Sauli
