    Question Bringing application to foreground


    My intention is to bring my application to foreground when a specific key is pressed. I know this has been discussed a number of times on the forum, but unfortunately its not working. Here is what I am doing. This is working fine on the emulator but not working on the device. Any clue why? I am using E61 & N73 to test.

    void CHighPrioAppUi::ConstructL()

    iAppView = CHighPrioAppView::NewL(ClientRect());


    // set application as system application so that it will not be closed by
    // system events
    CEikonEnv::Static()->SetSystem( ETrue );

    // capture red key permanently
    iHashKeyHandle = CEikonEnv::Static()->RootWin().CaptureKeyUpAndDowns(EStdKeyHash, 0, 0);

    // set application priority to foreground priority even if it goes to background
    CEikonEnv::Static()->WsSession().ComputeMode( RWsSession::EPriorityControlDisabled );

    // Make the application a high priority application
    CEikonEnv::Static()->RootWin().EnableReceiptOfFocus( ETrue );
    CEikonEnv::Static()->RootWin().SetOrdinalPosition(0, ECoeWinPriorityAlwaysAtFront);


    if (iAppView)
    delete iAppView;
    iAppView = NULL;

    void CHighPrioAppUi::HandleForegroundEventL (TBool aForeground)
    // Make the application a high priority application
    if (aForeground)
    CEikonEnv::Static()->RootWin().SetOrdinalPosition(0, ECoeWinPriorityAlwaysAtFront);

    // Handle Key Events in this
    void CHighPrioAppUi::HandleWsEventL (const TWsEvent &aEvent, CCoeControl *aDestination)
    if (aEvent.Type() == EEventKey ||
    aEvent.Type() == EEventKeyUp ||
    aEvent.Type() == EEventKeyDown ||
    aEvent.Type() == EEventKeyRepeat)
    // This is for switching back to Application when Hash key is pressed
    if (EStdKeyHash == aEvent.Key()->iScanCode && EEventKey == aEvent.Type())
    TApaTask task(iEikonEnv->WsSession());


    CAknAppUi::HandleWsEventL(aEvent, aDestination);

    Re: Bringing application to foreground

    I found the solution, it was because we didn't include the SwEvent capability in the MMP file.
