iOS: Software Keyboard Rectangle from QInputMethod

QMethodInput::keyboardRectangleChanged signal
is incoming properly when the sw-keyboard appears or closes
within a basic widget application,
i.e. added to textedit richtext example.

When trying to call in a slot for the above signal
keyboardRectangle() to get the keyboard area,
rather strange results have been observed.

An attempt instead of calling keyboardRectangle() in the slot
to postpone call to keyboardRectangle() by a short or even a long timer
has delivered the same results with no changes.

On iPad-3, Portrait:
The rectangle with keyboard UP:
xp=0
yp=760
w=768
h=264
The rectangle with keyboard CLOSED:
xp=0
yp=1024
w=768
h=264

On iPad-3, Landscape:
The rectangle with keyboard UP:
xp=0
yp=416
w=1024
h=352
The rectangle with keyboard CLOSED:
xp=0
yp=768
w=1024
h=352

Am I missing something or some re-interpretation of the
results required?
Thanks!
