Update only a particial area of a View with UpdateAllViews(...)
-
A simple call to InvalidateRect() in your OnUpdate() overrides should do it.
void CMyView::OnUpdate(CView* pSender, LPARAM /*lHint*/, CObject* pHint)
{
InvalidateRect((CRect*)pHint, TRUE);
}Mark

Sry, i was too fast, but your version won't work Too ! Thax for all your help & best regards Croc

Hi Mr. Salsbery, i tried
InvalidateRect((LPCRECT)pHint, TRUE);but it won't work :( Thanx for all your help Croc
What does "won't work" mean? If you're using a rect of (100,100,100,100) then nothing will happen, since the rect has no dimensions (width and height are 0). Try a valid rect! :) Mark

Hi, yes thats right but i tried it with
CRect MyRect(0,0, 200, 150); CObject\* pHint = (CObject\*)&MyRect;and this fails too! Manx thanx and best regards Croc

What does "fails" mean? Doesn't compile? Crashes at runtime? Nothing happens? It marks the area for updating. The next WM_PAINT message will update that area. If the same exact data is drawn as on the last WM_PAINT, you're not going to see a difference.

You need to change something between calls to UpdateAllViews() if you want to see something different in the view. What are your views drawing? Something from the document? If so, change the document.

Only you know what's going on in your views. The text data must be coming from somewhere... Change it and update the views! And make sure changing it doesn't already cause an update implicitly, or you still won't see anything. If the view is a window not in your control (where you don't do the painting, like an edit control), then you may not have control over updating regions of the window. If you are doing the painting in your view, look at the invalid rect in the WM_PAINT handler - you should see that your update rect is there. What you do with that info in your painting code is up to you. Mark

And you're using
SetWindowText()? I've not ever tried that, but it just seems odd."Love people and use things, not love things and use people." - Unknown
