What do you mean that it should not change? How does it change?

thanks wysota ...
actually i want to ignore the transformation of item in scene ...
i used ignore transformation flag in the graphicsItem...
Added after 5 minutes:
and im having the problem that .. if i try to rotate my graphicsItem ... it is shifting a little in y() also ...
Ex:
i tried to rotate a graphicsItem like a pendulum ...
i tried
item->setRotation(10);
but when it rotates it add its y() coordinates .. it is not rotating in constant axis ....
i need some suggestion ...
please help me ..
Thanks in advance ..
