Member Function Documentation

AttachWidget() [1/2]

void FSlotBase::AttachWidget ( const TSharedRef< SWidget > &  InWidget )

inline

AttachWidget() [2/2]

void FSlotBase::AttachWidget ( TSharedRef< SWidget > &&  InWidget )

inline

Attach the child widget the slot now owns.

DetachWidget()

const TSharedPtr< SWidget > FSlotBase::DetachWidget

(

)

Remove the widget from its current slot. The removed widget is returned so that operations could be performed on it. If the null widget was being stored, an invalid shared ptr is returned instead.

GetOwner()

const FChildren * FSlotBase::GetOwner ( ) const

inline

Access the FChildren that own the slot. The owner can be invalid when the slot is not attached.

GetOwnerWidget()

SWidget * FSlotBase::GetOwnerWidget

(

)

const

Access the widget that own the slot. The owner can be invalid when the slot is not attached.

GetWidget()

const TSharedRef< SWidget > & FSlotBase::GetWidget ( ) const

inline

Access the widget in the current slot. There will always be a widget in the slot; sometimes it is the SNullWidget instance.

Invalidate()

void FSlotBase::Invalidate

(

EInvalidateWidgetReason

InvalidateReason

)

Invalidate the widget's owner.

operator=()

FSlotBase & FSlotBase::operator= ( const FSlotBase &  )

delete

SetAttribute()

template<typename TargetValueType , typename SourceValueType >

bool FSlotBase::SetAttribute ( TAttribute< TargetValueType > &  TargetValue, const TAttribute< SourceValueType > &  SourceValue, EInvalidateWidgetReason  BaseInvalidationReason  )

inlineprotected

Performs the attribute assignment and invalidates the widget minimally based on what actually changed. So if the boundness of the attribute didn't change volatility won't need to be recalculated. Returns true if the value changed.

SetOwner()

void FSlotBase::SetOwner

(

const FChildren &

Children

)

Set the owner of the slot. Slots cannot be reassigned to different parents.
