How do you erase the CRectTracker and its styles?

Hi. I have a view which contains multiple static fields. When the user clicks on a static field, I add a CRectTracker over the static field. If there is another mouse click outside of the control with the CRectTracker, I want to delete the rect tracker and erase all remnants of it. I have tried simply deleting the rect tracker, redrawing the window, invalidating its rect, etc. Here is what I've tried:

// try clearing it's style
tracker->m_nStyle &= ~CRectTracker::hatchInside;
tracker->m_nStyle &= ~CRectTracker::dottedLine;
tracker->m_nStyle &= ~CRectTracker::resizeOutside;

// try invalidating its rect
CRect rectTrue;
tracker->GetTrueRect(&rectTrue);
InvalidateRect(rectTrue, TRUE);

// try redrawing the window it was used for
CWnd *trackingWnd = tracker->GetTrackingWnd();
trackingWnd->RedrawWindow();

// now just try deleting it.
delete tracker;
tracker = NULL;

Unfortunatley, with all of this, I still end up with the outline of the tracker on the screen. I don't want to redraw the entire view because there is too much screen flicker. Anybody have any ideas?

Thanks!

I don't see what function you are actually using (Draw, TrackRubberBand..) to draw it in the first place.

One thing you could try is to use a TRACE to find out the co-ordinates when you start the track and when you use this code
tracker->GetTrueRect(&rectTrue);
InvalidateRect(rectTrue, TRUE);

You may have a mis-match of screen and client co-ordinates

I use Draw to draw the tracker.

Tried your TRACE suggestion. The coordiantes are exactly the same. The only thing that seems to get the tracker to erase is a call to RedrawWindow, which redraws the entire CView.

YESSSS!! All it was was the rect param. I failed to pass a pointer to the rect. Sometimes the simplest things can make you crazy...Thanks for your help.

Yr welcome. (I'd not seen it either at first glance!)
