Symbian S60为功能键设置图片

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();
}
