开发伙伴平台：

S60 3rd Edition, FP2

详细描述

Command Button Array(CBA)在S60手机屏幕的下方（在竖屏模式下）。下列代码片段演示了如何设置为左右功能键设置图片。

#include <eikbtgpc.h>
#include <eikcba.h>     // link against avkon.lib, eikcoctl.lib
 
void SetCbaImage( CEikButtonGroupContainer* aBtGrC, 
             CEikImage& aImage, 
             TBool aLSK )
{
   TInt cmdPos = aLSK ? 0 : 2;
   TInt cmdId = aBtGrC->ButtonGroup()->CommandId( cmdPos );
   CEikCbaButton* button = 
     (CEikCbaButton*)aBtGrC->ControlOrNull( cmdId );
   if( button )
     {
     button->SetImage(aImage);
     aBtGrC->SetRect( aBtGrC->Rect() );
     aBtGrC->DrawNow();
     }
}

使用SetCbaImage()

_LIT(KCBAImageMBMFilename, "c:\\data\\images\\testimage.mbm");
TFileName mbmFile(KCBAImageMBMFilename);
 
cba = CEikButtonGroupContainer::Current();
if(cba)
{
   image = new (ELeave) CEikImage;
   CleanupStack::PushL( image );
   image->CreatePictureFromFileL( mbmFile, EMbmEnumLSKImage );
   image->SetBrushStyle(CGraphicsContext::ESolidBrush);
   CleanupStack::Pop( image ); 
 
   // Set image for LSK (ETrue as 3rd parameter)
   // Transfers ownership of image - do not delete yourself
   SetCbaImage( cba, *image, ETrue );
   image->DrawNow();
}
