它创建了3个窗口:

  • 第一个作为桌面的子窗口
  • 第二个作为第一个窗口的子窗口
  • 第三个作为第二个窗口的子窗口

窗口创建后，使用WM_ForEachDesc()在其父窗口中移动各个窗口：

 1 static void _cbWin(WM_MESSAGE * pMsg) { 2     GUI_COLOR Color; 3     switch (pMsg->MsgId) { 4         case WM_PAINT: 5         WM_GetUserData(pMsg->hWin, &Color, 4); 6         GUI_SetBkColor(Color); 7         GUI_Clear(); 8         break; 9         default:10         WM_DefaultProc(pMsg);11     }12 }13 /*********************************************************************14 *15 * _cbDoSomething16 */17 static void _cbDoSomething(WM_HWIN hWin, void * p) {18     int Value = http://www.mamicode.com/*(int *)p;19     WM_MoveWindow(hWin, Value, Value);20 }21 /*********************************************************************22 *23 * MainTask24 */25 void Fun(void) {26     WM_HWIN hWin_1, hWin_2, hWin_3;27     int Value = http://www.mamicode.com/10;28     GUI_COLOR aColor[] = {GUI_RED, GUI_GREEN, GUI_BLUE};29     GUI_Init();30     WM_SetDesktopColor(GUI_BLACK);31     hWin_1 = WM_CreateWindow( 10, 10, 100, 100, WM_CF_SHOW, _cbWin, 4);32     hWin_2 = WM_CreateWindowAsChild(10, 10, 80, 80, hWin_1, WM_CF_SHOW, _cbWin, 4);33     hWin_3 = WM_CreateWindowAsChild(10, 10, 60, 60, hWin_2, WM_CF_SHOW, _cbWin, 4);34     WM_SetUserData(hWin_1, &aColor[0], 4);35     WM_SetUserData(hWin_2, &aColor[1], 4);36     WM_SetUserData(hWin_3, &aColor[2], 4);37     while (1) {38         WM_ForEachDesc(WM_HBKWIN, _cbDoSomething, (void *)&Value);39         Value *= -1;40         GUI_Delay(500);41     }42 }
  • 前两个为回调函数，Fun函数为主函数，建立3个窗口
  • WM_HWIN WM_CreateWindow(int x0, int y0,
    int width, int height,
    U8 Style, WM_CALLBACK * cb
    int NumExtraBytes);
  • WM_HWIN WM_CreateWindowAsChild(int x0, int y0,
    int width, int height,
    WM_HWIN hWinParent,
    U8 Style,
    WM_CALLBACK* cb
    int NumExtraBytes);
  • void WM_ForEachDesc(WM_HWIN hWin, WM_tfForEach * pcb, void * pData);
