regarding menu pane in UIQ

Hi all,
I am a bit new for UIQ platform. So I am wondered to see the changes respect to series 60.
Actually my motive is to draw a customized menu pane or control in which i could provide desired look and feel for menupane.
I saw some APIs in UIQ SDK. There is a class CQikMenuPopout which contains CEikMenuPane object.
It can draw menupane with the help of function
iMenuPopout->DisplayL(position, EPopupTargetTopLeft);
This function is working properly;

SDK says that it returns the CEikMenuPane pointer also for direct manipulation. But function is always returning null.
I tried following code snippet but menuPane is null.

CEikMenuPane* menuPane;
menuPane = iMenuPopout->MenuPane();
Does this function not work in UIQ platform.

One more thing I would like to know when we press softkey in a view, where control goes actually. I mean
is it HandleCommandL() or OfferKeyEventL() or somewhere else. I need to know the function name which is responsible for opening menuPane.

Thanks in advance.
