Detailed Description

FChildren is an interface that must be implemented by all child containers. It allows iteration over a list of any Widget's children regardless of how the underlying Widget happens to store its children.

FChildren is intended to be returned by the GetChildren() method.

There is no guarantee that it will work. The memory could have been reused and the new data can luckily matches what we are looking for.

◆ ForEachWidget() [1/2]

template<typename Predicate >

void FChildren::ForEachWidget ( Predicate && Pred )

inline

Applies the predicate to all the widgets contained by the FChildren.

◆ ForEachWidget() [2/2]

template<typename Predicate >

void FChildren::ForEachWidget ( Predicate && Pred ) const

inline

Applies the predicate to all the widgets contained by the FChildren.

◆ GetChildAt() [1/2]

virtual TSharedRef< const SWidget > FChildren::GetChildAt ( int32 Index ) const

pure virtual

Returns: const pointer to the Widget at the specified Index.

◆ GetChildAt() [2/2]

virtual TSharedRef< SWidget > FChildren::GetChildAt ( int32 Index )

pure virtual

Returns: pointer to the Widget at the specified Index.

◆ GetChildRefAt() [1/2]

virtual FConstWidgetRef FChildren::GetChildRefAt ( int32 Index ) const

protectedpure virtual

Returns: ref to the Widget at the specified Index.

◆ GetChildRefAt() [2/2]

virtual FWidgetRef FChildren::GetChildRefAt ( int32 Index )

protectedpure virtual

Returns: ref to the Widget at the specified Index.

◆ GetName()

FName FChildren::GetName ( ) const

inline

Option to give a name to Children to SlotAttribute purposes or for debugging.

◆ GetOwner()

SWidget & FChildren::GetOwner ( ) const

inline

Returns: the SWidget that own the FChildren

◆ GetSlotAt()

virtual const FSlotBase & FChildren::GetSlotAt ( int32 ChildIndex ) const

pure virtual

Returns: the const reference to the slot at the specified Index

◆ Num()

virtual int32 FChildren::Num ( ) const

pure virtual

Returns: the number of children

◆ NumSlot()

virtual int32 FChildren::NumSlot ( ) const

inlinevirtual

Returns: the number of slot the children has.

Reimplemented in FCombinedChildren.
