Question:
I am writing a test driver for my application and I want to simulate the sending of key presses to the window server. How do I do this?

Answer:
You can use the SimulateKeyEvent(TKeyEvent) method of RWsSession as follows. There is a corresponding SimulateRawEvent(TRawEvent) if you want to generate scan codes. The latter also works under v5 of Symbian OS - see FAQ-0292

RWsSession& wsSession=iCoeEnv->WsSession();
TKeyEvent keyEvent;
keyEvent.iCode = EKeyPageDown; // member of TKeyCode
keyEvent.iScanCode = EKeyPageDown;
keyEvent.iModifiers = 0;
keyEvent.iRepeats = 0;
wsSession.SimulateKeyEvent(keyEvent);
wsSession.Flush();
