提供一种自画式菜单设计方法及实现

class CEZMenuItemData
{
public:
	CEZMenuItemData();
	HICON hItemIconLarge;//大图标句柄
	HICON hItemIconSmall;//小图标句柄
	CString strItemText;//菜单字符串
	BOOL bChecked;      //这一项是否被选中
	BOOL bSeperator;    //是否需要分隔线
	BOOL bProgress;     //是否需要进度条
	int nProgress;      //进度条所显示的百分比
};

//Useful typedef
typedef  CEZMenuItemData*  LPEZMENUITEMDATA;
class CEZMenu:public CMenu
{
public:
	CEZMenu();
	void InsertOwnerDrawnMenuItem(UINT nID,LPEZMENUITEMDATA lpez,int nPos=0);
	void AppendOwnerDrawnItem(UINT nID,LPEZMENUITEMDATA lpez);
	void ModifyOwnerDrawnMenuItem(int nPos,UINT nID,int nTotalCheck,LPEZMENUITEMDATA lpez);
	void SetTotalItems(int nItems);//这个函数是必须的
	void SetMenuBitmap(HBITMAP hBitmap);
	void SetExtensionColor(COLORREF clrExtend);//如果位图高度比菜单高度小
	void SetBitmapDimension(CSize sz);
	void SetLargeIcon(BOOL bLarge=FALSE);//大图标还是小图标
	void DrawItem(LPDRAWITEMSTRUCT lpDrawItemStruct);
	void MeasureItem(LPMEASUREITEMSTRUCT lpMeasureItemStruct);
	~CEZMenu();
private:
	int m_nCount;//中间变量
	int m_nAveHeight;//每个菜单项的平均高度
	int m_nItems;//菜单项的数目
	COLORREF m_clrExtend;//扩展颜色
	BOOL m_bLargeIcons;
	CSize m_szBitmapSize;
	CBitmap m_bitmap;
};
