本文详细介绍了如何使用CoeControl、AknSingleGraphicStyleListBox等类构建具有自定义样式的列表框，包括初始化控件、设置样式、添加项、图标配置及激活等功能。

.h 文件:

#include <coecntrl.h>
#include <akniconutils.h>
#include <gulicon.h>
#include <eiklbo.h>

class MEikCommandObserver;
class CAknSingleGraphicStyleListBox;
class CEikTextListBox;

class CTestContainer : public CCoeControl

{

......

private:
CAknSingleGraphicStyleListBox* iListBox;

......

}

.cpp 文件

#include <avkon.mbg> //For EMbmAvkonQgn_indi_checkbox_on/off and EMbmAvkonQgn_indi_checkbox_on/off_mask
