MiniGUI原理分析 控件

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_STATIC    if (!RegisterStaticControl ())        return FALSE;#endif#ifdef _MGCTRL_BUTTON    if (!RegisterButtonControl())        return FALSE;#endif#ifdef _MGCTRL_SLEDIT    if (!RegisterSLEditControl())        return FALSE;#endif#ifdef _MGCTRL_BIDISLEDIT    if (!RegisterBIDISLEditControl())        return FALSE;#endif#ifdef _MGCTRL_PROGRESSBAR    if (!RegisterProgressBarControl())        return FALSE;#endif#ifdef _MGCTRL_LISTBOX    if (!RegisterListboxControl())        return FALSE;#endif#ifdef _MGCTRL_NEWTOOLBAR    if (!RegisterNewToolbarControl())        return FALSE;#endif#ifdef _MGCTRL_MENUBUTTON    if (!RegisterMenuButtonControl())        return FALSE;#endif#ifdef _MGCTRL_TRACKBAR    if (!RegisterTrackBarControl())        return FALSE;#endif#ifdef _MGCTRL_COMBOBOX    if (!RegisterComboBoxControl())        return FALSE;#endif#ifdef _MGCTRL_PROPSHEET    if (!RegisterPropSheetControl())        return FALSE;#endif#ifdef _MGCTRL_SCROLLVIEW    if (!RegisterScrollViewControl ())        return FALSE;    if (!RegisterScrollWndControl ())        return FALSE;#endif#ifdef _MGCTRL_TEXTEDIT    if (!RegisterTextEditControl ())        return FALSE;#endif#ifdef _MGCTRL_TREEVIEW    if (!RegisterTreeViewControl ()) {        _MG_PRINTF ("Init MiniGUI control error: TreeView.\n");        return FALSE;    }#endif#ifdef _MGCTRL_TREEVIEW_RDR    if (!RegisterTreeViewRdrControl ()) {        _MG_PRINTF ("Init MiniGUI control error: TreeView_rdr.\n");        return FALSE;    }#endif#ifdef _MGCTRL_MONTHCAL    if (!RegisterMonthCalendarControl ()) {        _MG_PRINTF ("Init MiniGUI control error: MonthCalendar.\n");        return FALSE;    }#endif#ifdef _MGCTRL_SPINBOX    if (!RegisterSpinControl ()) {        _MG_PRINTF ("Init MiniGUI control error: Spin.\n");        return FALSE;    }#endif#ifdef _MGCTRL_COOLBAR    if (!RegisterCoolBarControl ()) {        _MG_PRINTF ("Init MiniGUI control error: CoolBar.\n");        return FALSE;    }#endif#ifdef _MGCTRL_LISTVIEW    if (!RegisterListViewControl ()) {        _MG_PRINTF ("Init MiniGUI control error: ListView.\n");        return FALSE;    }#endif#ifdef _MGCTRL_GRIDVIEW    if (!RegisterGridViewControl ()) {        _MG_PRINTF ("Init MiniGUI control error: GridView.\n");        return FALSE;    }#endif#ifdef _MGCTRL_ICONVIEW    if (!RegisterIconViewControl ()) {        _MG_PRINTF ("Init MiniGUI control error: IconView.\n");        return FALSE;    }#endif#ifdef _MGCTRL_ANIMATION    if (!RegisterAnimationControl ()) {        _MG_PRINTF ("Init MiniGUI control error: Animation.\n");        return FALSE;    }#endif#ifdef _MGCTRL_SCROLLBAR    if (!RegisterScrollBarControl ()) {        _MG_PRINTF ("Init MiniGUI control error: ScrollBar.\n");        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);}
