示例1:

//
/// Called by Paint to repaint all of the gadgets, PaintGadgets iterates through the
/// list of gadgets, determines the gadget's area, and repaints each gadget.
/// 
/// You can override this function to implement a specific look (for example,
/// separator line, raised, and so on).
//
void
TGadgetWindow::PaintGadgets(TDC& dc, bool, TRect& rect)
{
  TPoint viewport = dc.GetViewportOrg();
  for (TGadget* gadget = Gadgets; gadget; gadget = gadget->Next) {
    if (gadget->GetBounds().Touches(rect)) {
      dc.SetViewportOrg((TPoint&)gadget->GetBounds());

      // If the gadget is a sloppy painter & needs clipping support, set the
      // clip rect before painting, otherwise just paint. Most gadgets don't
      // need this help
      //
      if (gadget->Clip) {
        TRegion savedClipRgn;
        dc.GetClipRgn(savedClipRgn);
        dc.IntersectClipRect(gadget->GetBounds());

        gadget->Paint(dc);

        dc.SelectClipRgn(savedClipRgn);
      }
      else
        gadget->Paint(dc);
    }
  }
  dc.SetViewportOrg(viewport);
}

示例2: offset

//
/// If TScroller_AutoOrg is true (default condition), BeginView automatically
/// offsets the origin of the logical coordinates of the client area by XPos, YPos
/// during a paint operation. If AutoOrg is false (for example, when the scroller is
/// larger than 32,767 units), you must set the offset manually.
//
void
TScroller::BeginView(TDC& dc, TRect& rect)
{
    long  xOrg = XPos * XUnit;
    long  yOrg = YPos * YUnit;

    if (AutoOrg && xOrg <= INT_MAX && yOrg <= INT_MAX) {
        TPoint offset(int(-xOrg), int(-yOrg));
        dc.SetViewportOrg(offset);
        rect -= offset;
    }
}
