C++ (Cpp) UnsetClip Examples

Example #1

File: widget_list.cpp Project: fluxer/warmux

void WidgetList::Draw(const Point2i &mousePosition)
{
  Rectanglei clip;
  Rectanglei wlr = GetClip(clip);
  if (!wlr.GetSizeX() || !wlr.GetSizeY())
      return;

  for (std::list<Widget*>::const_iterator w=widget_list.begin();
      w != widget_list.end();
      w++)
  {
    Rectanglei r((*w)->GetPosition(), (*w)->GetSize());
    r.Clip(wlr);

    if (r.GetSizeX() && r.GetSizeY()) {
      Rectanglei wr = r;
      SwapWindowClip(r);
      (*w)->RedrawBackground(wr);
      (*w)->Draw(mousePosition);
      (*w)->RedrawForeground();
      SwapWindowClip(r);
    }
  }

  // Restore initial clip rectangle
  UnsetClip(clip);
}

Example #2

File: widget_list.cpp Project: fluxer/warmux

bool WidgetList::Update(const Point2i& mousePosition,
                        const Point2i& lastMousePosition)
{
  Rectanglei clip;
  Rectanglei wlr = GetClip(clip);
  if (!wlr.GetSizeX() || !wlr.GetSizeY())
      return false;

  // Redraw the background
  bool updated = false;
  if (need_redrawing)
    RedrawBackground(wlr);

  for (std::list<Widget*>::const_iterator w=widget_list.begin();
      w != widget_list.end();
      w++)
  {
    Rectanglei r((*w)->GetPosition(), (*w)->GetSize());
    r.Clip(wlr);

    if (r.GetSizeX() && r.GetSizeY()) {
      SwapWindowClip(r);
      updated |= (*w)->Update(mousePosition, lastMousePosition);
      SwapWindowClip(r);
    }
  }

  if (updated)
    RedrawForeground();

  // Restore initial clip rectangle
  UnsetClip(clip);
  need_redrawing = false;
  return updated;
}

Example #3

File: text_box.cpp Project: yeKcim/warmux

void TextBox::Draw(const Point2i & mousePosition)
{
  Rectanglei clip;
  Rectanglei wlr = GetClip(clip);
  if (!wlr.GetSizeX() || !wlr.GetSizeY())
      return;

  Label::Draw(mousePosition);
  DrawCursor(position, cursor_pos);

  // Restore initial clip rectangle
  UnsetClip(clip);
