关于使用多页贴图后内存不释放

waszhang

现在遇到一个问题：在使用多页贴图后，每进入退出一次，SDRAM使用量多出200多个字节，不会释放；如果屏蔽了代码中红色部分，SDRAM第一次调用后，不再增加。如果贴图不知如何释放每次多出来的SDRAM开销？
也使用过MULTIPAGE_SetBitmap（）函数，效果一样，不释放。

代码如下：
页面创建：
WM_HWIN CreateSETTING(WM_HWIN hMWIN)
{

  hSWin = GUI_CreateDialogBox(_aDialogCreate1, GUI_COUNTOF(_aDialogCreate1), _cbDialog, hMWIN, 0, 0);
  return hSWin;
}
页面回调函数：
static void _cbDialog(WM_MESSAGE * pMsg) {
  WM_HWIN hItem;
  WM_HWIN hMultiPage;
  WM_HWIN hDialog;
  int     NCode;
  int     Id;
  // USER START (Optionally insert additional variables)
  // USER END

  switch (pMsg->MsgId) {
  case WM_INIT_DIALOG:
    //
    // Initialization of 'SETTING(define)'
    //
    hItem = pMsg->hWin;
    FRAMEWIN_SetTitleVis(hItem, 0);
    //
    // Initialization of 'Header'
    //
    hItem = WM_GetDialogItem(pMsg->hWin, ID_HEADER_0);
    HEADER_SetTextColor(hItem,GUI_WHITE);
    HEADER_SetBkColor(hItem,0x00a57001);
    HEADER_SetFont(hItem,GUI_FONT_32B_ASCII);//GUI_FONT_24B_ASCII
    HEADER_AddItem(hItem, 710, " ", GUI_TA_HCENTER|GUI_TA_VCENTER);
    HEADER_SetHeight(hItem,60);
    HEADER_SetItemText(hItem,0,"Quick Settings");

    hItem = WM_GetDialogItem(pMsg->hWin, ID_BUTTON_0);
    BUTTON_SetBitmapEx(hItem,0,&bmreturn,1,1);
    BUTTON_SetBitmapEx(hItem,1,&bmreturn,1,1);
    BUTTON_SetBitmapEx(hItem,2,&bmreturn,1,1);
    BUTTON_SetFocussable(hItem,1);
    //
    // Initialization of 'Multipage'
    //
    hMultiPage = WM_GetDialogItem(pMsg->hWin, ID_MULTIPAGE_0);
    MULTIPAGE_SetTabHeight(hMultiPage, 90);
    MULTIPAGE_SetAlign(hMultiPage,MULTIPAGE_ALIGN_LEFT | MULTIPAGE_ALIGN_BOTTOM);
    MULTIPAGE_SetRotation(hMultiPage,MULTIPAGE_CF_ROTATE_CW);
    MULTIPAGE_SetFont(hMultiPage, GUI_FONT_24B_1);
    MULTIPAGE_EnableScrollbar(hMultiPage,0);

    hDialog = GUI_CreateDialogBox(_aQTSettingCreate,GUI_COUNTOF(_aQTSettingCreate),_cbQTSettingDialog,hSWin,0,0); //WM_UNATTACHED
    MULTIPAGE_AddPage(hMultiPage,hDialog,"");
    MULTIPAGE_SetTabWidth(hMultiPage, 208,0);
    MULTIPAGE_SetBitmapEx(hMultiPage,&bm21,0,0,0,MULTIPAGE_BI_SELECTED);

    hDialog = GUI_CreateDialogBox(_aUVSettingCreate,GUI_COUNTOF(_aUVSettingCreate),_cbUVSettingDialog,hSWin ,0,0); //WM_UNATTACHED
    MULTIPAGE_AddPage(hMultiPage,hDialog, "");
    MULTIPAGE_SetTabWidth(hMultiPage, 208,1);
    MULTIPAGE_SetBitmapEx(hMultiPage,&bm24,0,0,1,MULTIPAGE_BI_SELECTED);
    MULTIPAGE_SetBitmapEx(hMultiPage,&bm23,0,0,1,MULTIPAGE_BI_UNSELECTED);

给这个多页对话框界面回调消息里面加上个WM_DELETE:，如果你关闭此对话框的时候，会进入到这个消息，然后你在这个消息里面
调用函数MULTIPAGE_DeletePage把所有创建的页都单独删除一遍，看看是否可行。

试过了，不行。不知为啥？
  case WM_DELETE:
      MULTIPAGE_DeletePage(WM_GetDialogItem(pMsg->hWin, ID_MULTIPAGE_0),0,1);
      MULTIPAGE_DeletePage(WM_GetDialogItem(pMsg->hWin, ID_MULTIPAGE_0),1,1);
      hDialog = NULL;
      hMultiPage = NULL;
      hSWin = NULL;
      break;

也许是个bug，后面我也测试下看看。
