Example

Assumes pVectorWindow points to a valid LVectorWindow object.

This example centers the LVectorWindow object in the parent window.

L_INT LVectorWindow__GetVectorWndExample(LVectorWindow *pVectorWindow)
{
   L_INT    nRet;
   RECT     parentRect, vectorRect, moveRect;
   L_INT    moveWidth, moveHeight;
   HWND     hWndParent = ::GetParent(pVectorWindow->GetVectorWnd());
   if (hWndParent != NULL)
   {
      ::GetClientRect(hWndParent, &parentRect);
      nRet = pVectorWindow->GetVectorRect(&vectorRect);
      if(nRet != SUCCESS)
         return nRet;
      moveWidth = vectorRect.right - vectorRect.left;
      moveHeight = vectorRect.bottom - vectorRect.top;
      moveRect.left = ((parentRect.right - parentRect.left) - moveWidth)/2;
      moveRect.top  = ((parentRect.bottom - parentRect.top) - moveHeight)/2;
      moveRect.right = moveRect.left + moveWidth;
      moveRect.bottom = moveRect.top + moveHeight;
      nRet = pVectorWindow->Move(moveRect, TRUE);
      if(nRet != SUCCESS)
         return nRet;
   }
   return SUCCESS;
