示例1: OnArrangeChildren
void SClippingHorizontalBox::OnArrangeChildren( const FGeometry& AllottedGeometry, FArrangedChildren& ArrangedChildren ) const
{
// If WrapButton hasn't been initialized, that means AddWrapButton() hasn't
// been called and this method isn't going to behave properly
check(WrapButton.IsValid());
SHorizontalBox::OnArrangeChildren(AllottedGeometry, ArrangedChildren);
// Remove children that are clipped by the allotted geometry
const int32 NumChildren = ArrangedChildren.Num();

for (int32 ChildIdx = NumChildren - 2; ChildIdx >= 0; --ChildIdx)
{
