C++ (Cpp) TSharedRef::GetChildren Examples

Example #1

File: SDetailsViewBase.cpp Project: PickUpSU/UnrealEngine4

void SDetailsViewBase::SetNodeExpansionState(TSharedRef<IDetailTreeNode> InTreeNode, bool bIsItemExpanded, bool bRecursive)
{
	TArray< TSharedRef<IDetailTreeNode> > Children;
	InTreeNode->GetChildren(Children);

	if (Children.Num())
	{
		RequestItemExpanded(InTreeNode, bIsItemExpanded);
		InTreeNode->OnItemExpansionChanged(bIsItemExpanded);

		if (bRecursive)
		{
			for (int32 ChildIndex = 0; ChildIndex < Children.Num(); ++ChildIndex)
			{
				TSharedRef<IDetailTreeNode> Child = Children[ChildIndex];

				SetNodeExpansionState(Child, bIsItemExpanded, bRecursive);
			}
		}
	}
}

Example #2

File: SlateTextLayout.cpp Project: xiangyuan/Unreal4

void FSlateTextLayout::AggregateChildren()
{
	Children.Empty();
	const TArray< FLineModel >& LineModels = GetLineModels();
	for (int32 LineModelIndex = 0; LineModelIndex < LineModels.Num(); LineModelIndex++)
	{
		const FLineModel& LineModel = LineModels[ LineModelIndex ];
		for (int32 RunIndex = 0; RunIndex < LineModel.Runs.Num(); RunIndex++)
		{
			const FRunModel& LineRun = LineModel.Runs[ RunIndex ];
			const TSharedRef< ISlateRun > SlateRun = StaticCastSharedRef< ISlateRun >( LineRun.GetRun() );

			const TArray< TSharedRef<SWidget> >& RunChildren = SlateRun->GetChildren();
			for (int32 ChildIndex = 0; ChildIndex < RunChildren.Num(); ChildIndex++)
			{
				const TSharedRef< SWidget >& Child = RunChildren[ ChildIndex ];
				Children.Add( Child );
			}
		}
	}
}
