五．控件分析

5.1 控件管理的基本数据结构

typedef struct _CTRLCLASSINFO
{
    char      name[MAXLEN_CLASSNAME + 1];// class name
    /*
     * common properties of this class
     */
    DWORD     dwStyle;          // Default control styles.
    DWORD     dwExStyle;        // Default control extended styles.
    HCURSOR   hCursor;          // control cursor
    int       iBkColor;         // control background color.
    int (*ControlProc)(HWND, int, WPARAM, LPARAM); // control procedure.
    DWORD dwAddData;            // the additional data.
    int nUseCount;              // use count.
    struct _CTRLCLASSINFO*  next;  // next class info
}CTRLCLASSINFO;

5.2 控件管理全局变量

static PCTRLCLASSINFO ccitable[LEN_CCITABLE];

5.3 控件注册到ccitable

BOOL mg_InitControlClass ()      //注册控件
{
    int i;
    for (i=0; i<LEN_CCITABLE; i++)
        ccitable[i] = NULL;
    // Register system controls here.

#ifdef _MGCTRL_TREEVIEW
    if (!RegisterTreeViewControl ()) {

        return FALSE;
    }
#endif
#ifdef _MGCTRL_TREEVIEW_RDR
    if (!RegisterTreeViewRdrControl ()) {

        return FALSE;
    }
#endif
#ifdef _MGCTRL_COOLBAR
    if (!RegisterCoolBarControl ()) {

        return FALSE;
    }
#endif
#ifdef _MGCTRL_LISTVIEW
    if (!RegisterListViewControl ()) {

        return FALSE;
    }
#endif
#ifdef _MGCTRL_GRIDVIEW

        return FALSE;
    }
#endif
    return TRUE;
}

5.4 控件的创建和主窗口的创建

控件：

#define CreateWindow(class_name, caption, style, id, x, y, w, h, parent, add_data)       \
        CreateWindowEx(class_name, caption, style, 0, id, x, y, w, h, parent, add_data)

主窗口：

static inline HWND GUIAPI CreateMainWindow (PMAINWINCREATE pCreateInfo)
{
    return CreateMainWindowEx (pCreateInfo, NULL, NULL, NULL, NULL);
}
