示例1: if
Widget *Container::GetWidgetAt(const Point &pos)
{
if (!Contains(pos)) return 0;
for (WidgetIterator i = WidgetsBegin(); i != WidgetsEnd(); ++i) {
Widget *widget = (*i).Get();
const Point relpos = pos - widget->GetPosition() - widget->GetDrawOffset();
if (widget->IsContainer()) {
Widget* w = static_cast<Container*>(widget)->GetWidgetAt(relpos);
if (w) return w;
} else if (widget->Contains(relpos))
return widget;
}
return this;
}示例2: MarkDirtyFull
void WidgetContainer::MarkDirtyFull(WidgetContainer* theWidget)
{
// Mark all things dirty that are under or over this widget
// Mark ourselves dirty
MarkDirtyFull();
theWidget->mDirty = true;
// Top-level windows are treated differently, as marking a child dirty always
// causes a parent redraw which always causes all children to redraw
if (mParent != NULL)
return;
WidgetList::iterator aFoundWidgetItr = std::find(mWidgets.begin(), mWidgets.end(), theWidget);
if (aFoundWidgetItr == mWidgets.end())

{
if ((!aWidget->mHasTransparencies) && (!aWidget->mHasAlpha))

// If it is fully overlapped then we can stop marking dirty underneath it since it's not transparent.
Rect aRect = Rect(theWidget->mX,theWidget->mY,theWidget->mWidth,theWidget->mHeight).Intersection(Rect(0,0,mWidth,mHeight));

// If this widget is fully contained within a lower widget, there is no need to dig down
// any deeper.
aWidget->MarkDirty();
break;
}
}
if (aWidget->Intersects(theWidget))
