UpdateAllViews

[sawer]

Hi

When clicks on View, my program draws ellipse and I tried to make all changes in one view reflects to all views.

1-)OnLbuttonDown adds a point to CArray m_PointList

2-)UpdateAllViews calls OnUpdate

3-) OnUpdate Invaliates so OnDraw called.

void CDocumentView::OnLButtonDown(UINT nFlags, CPoint point)
{
	GetDocument()->m_PointList.Add(point);
	GetDocument()->UpdateAllViews(NULL);

	CView::OnLButtonDown(nFlags, point);
};
//
void CDocumentView::OnDraw(CDC* pDC)
{
	CDocumentDoc* pDoc = GetDocument();
	ASSERT_VALID(pDoc);
	if (!pDoc)
		return;
	for(int i = 0; i < GetDocument()->m_PointList.GetCount(); i++)
	{
		pDC->Ellipse(GetDocument()->m_PointList[i].x - GetDocument()->m_PointSize, GetDocument()->m_PointList[i].y - GetDocument()->m_PointSize,
			GetDocument()->m_PointList[i].x + GetDocument()->m_PointSize, GetDocument()->m_PointList[i].y + GetDocument()->m_PointSize);
	}
}
//
void CDocumentView::OnUpdate(CView* /*pSender*/, LPARAM /*lHint*/, CObject* /*pHint*/)
{
	// TODO: Add your specialized code here and/or call the base class
	Invalidate();
}

But when i open a new document, it doesn't draw ellipse which is m_PointList , it shows a clean view window. And when i started to click also it doesn't change the other views.

Where am i wrong?
