动态改变 CBA 按钮

http://forum.newlc.com/index.php/topic,12882.0.html

Code:
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:

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

In your application's AppUi class:

Code:
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.
