怎么用tooltip弹出提示框实时的现实鼠标坐标的位置？搞了一天了都没有搞定。

经常碰到坐标不更新及显示之后移动了鼠标TIP没有及时跟上的问题

你哪里老大做过，贴个代码来看看啊。。。



void     TForm2::AddToolTip(HWND     hWnd     ,int     IconType,char     *Text,char     *Title     ,

      TColor     BackColor,TColor     TextColor,int x,int y)

{

   TToolInfo  ToolInfo;

    char buffer[256];

    TRect Rect;

    TPoint lpPoint;   // screen coordinates

    lpPoint.x = x;

    lpPoint.y = y;

    ::ClientToScreen(hWnd,&lpPoint);

    if(hTooltip != 0)

    {

        SetWindowPos(hTooltip, 0/*HWND_TOPMOST*/, lpPoint.x, lpPoint.y, 0, 0,/*SWP_NOMOVE|SWP_NOSIZE|*/SWP_NOACTIVATE|SWP_SHOWWINDOW);

        ToolInfo.cbSize =  sizeof(TToolInfo);

        ToolInfo.uFlags =  TTF_SUBCLASS;//|TTF_TRANSPARENT;

        ToolInfo.hinst  =  NULL;

    }

    else

    {

        hTooltip = 0;

    }

    //Rect = GetClientRect();

    ::GetClientRect(hWnd, &Rect);

    if(hWnd != 0 )

    {

        ToolInfo.hwnd=hWnd;

        ToolInfo.rect=Rect;

        ToolInfo.lpszText=Text;

        SendMessage(hTooltip,TTM_ADDTOOL,0,int(&ToolInfo));

        memset(buffer,sizeof(buffer),'0');

        lstrcpy(buffer,Title);

        if(IconType > 3||IconType < 0)

            IconType = 0;

        if(BackColor!=0)

            SendMessage(hTooltip,TTM_SETTIPBKCOLOR,BackColor,0);

        if(TextColor!=0)

            SendMessage(hTooltip,TTM_SETTIPTEXTCOLOR,TextColor,0);

        if(Title!=0)

            SendMessage(hTooltip,TTM_SETTITLE,IconType,int(&buffer));

    }

//    OldWindowProc = (WNDPROC)::GetWindowLong(hTooltip, GWL_WNDPROC);

//    ::SetWindowLong(hTooltip, GWL_WNDPROC, (LONG)NewWindowProc);

}

void __fastcall TForm2::FormMouseMove(TObject *Sender, TShiftState Shift, int X,

      int Y)

{

    String strPoint = "";

    TVarRec args[2] = {X,Y};

    strPoint = Format("%d,%d",args,2);

    AddToolTip(this->Handle, 1,strPoint.c_str() , Application->Title.c_str(),(TColor)0,(TColor)0,X,Y);

}
