* 详细描述
我们可以使用NAVI_IMAGE资源描述来指定导航栏的图片。这个资源有三个字段需要定义：

'''bmpfile''' 指定一个mbm文件

'''bmpid''' 指定mbm文件中某个图片的index值

'''bmpmask''' 可选，用来指定mbm文件中某个遮罩文件的index值


下列代码片段是rss文件中定义的:
<code cpp>
#include <avkon.mbg>
 
RESOURCE NAVI_IMAGE r_yourapplication_navi_image
   {
 
   bmpfile = "\\system\data\avkon.mbm"; // or KAvkonBitmapFile define in  avkon.rh
 
   bmpid = EMbmAvkonQgn_stat_keyguard;
 
   }
</code>

bmpfile字段指定了mbm文件的位置，然后可以使用指定具体图片的字段

<code cpp>
TUid naviPaneUid;
naviPaneUid.iUid = EEikStatusPaneUidNavi;
CEikStatusPane* statusPane = StatusPane();
CEikStatusPaneBase::TPaneCapabilities subPane = statusPane->PaneCapabilities(naviPaneUid);
 
// if we can access the navigation pane
 
if (subPane.IsPresent() && subPane.IsAppOwned())
{
	CAknNavigationControlContainer* naviPane = (CAknNavigationControlContainer*)statusPane->ControlL

(naviPaneUid);
 
 
 
            // read the navigation pane image resource
            TResourceReader reader;
 
 
            iCoeEnv->CreateResourceReaderLC(reader, R_YOURAPPLICATION_NAVI_IMAGE);
 
            if (iNaviDecorator)
            {
 
	               delete iNaviDecorator;
	               iNaviDecorator = NULL;
 
            }
 
           // set the navigation pane image
            iNaviDecorator = naviPane->CreateNavigationImageL(reader);
           // pushed by CreateResourceReaderLC
           CleanupStack::PopAndDestroy(); 
           naviPane->PushL(*iNaviDecorator);
}
</code>
