[Symbian] 改变窗口的CBA

In the RSS file:

RESOURCE CBA r_yourapp_softkeys_options_open
{
    buttons =
    {
        CBA_BUTTON { id=EAknSoftkeyOptions; txt = "Options"; },
CBA_BUTTON { id=EYourAppCmdOpenApp; txt = "Open"; }
    };
}

RESOURCE CBA r_yourapp_softkeys_options_stop
{
    buttons =
    {
CBA_BUTTON { id=EAknSoftkeyOptions; txt = "Options"; },
CBA_BUTTON { id=EYourAppCmdStopApp; txt = "Stop"; }
    };
}

In the HRH file:

enum TYourAppCommandIds
{
    // ...
    id=EYourAppCmdOpenApp,
    id=EYourAppCmdStopApp,
    // ...
};

In your application's AppUi class:

void CYourAppUi::SetCommandSetL(TInt aResourceId)
{
    CEikButtonGroupContainer* cba = CEikButtonGroupContainer::Current();
    cba->SetCommandSetL( aResourceId );
}

Now you can call:

SetCommandSetL( R_YOURAPP_SOFTKEYS_OPTIONS_OPEN );
OR
SetCommandSetL( R_YOURAPP_SOFTKEYS_OPTIONS_STOP );

where ever you want.

Change the cba of dialog, you can call SetCommandSetL with argument R_AVKON_SOFTKEYS_XXX directly.
