Constructor & Destructor Documentation

FPropertyChangedEvent()

FPropertyChangedEvent::FPropertyChangedEvent ( FProperty *  InProperty, EPropertyChangeType::Type  InChangeType = EPropertyChangeType::Unspecified, TArrayView< const UObject *const >  InTopLevelObjects = TArrayView<const UObject* const>()  )

inline

Member Function Documentation

GetArrayIndex()

int32 FPropertyChangedEvent::GetArrayIndex ( const FString &  InName ) const

inline

Gets the Array Index of the "current object" based on a particular name InName - Name of the property to find the array index for

GetArrayIndicesPerObject()

bool FPropertyChangedEvent::GetArrayIndicesPerObject ( int32  InObjectIteratorIndex, TMap< FString, int32 > &  OutArrayIndicesPerObject  ) const

inline

GetMemberPropertyName()

FName FPropertyChangedEvent::GetMemberPropertyName ( ) const

inline

Simple utility to get the name of the object's member property and takes care of the possible null property.

GetNumObjectsBeingEdited()

int32 FPropertyChangedEvent::GetNumObjectsBeingEdited ( ) const

inline

Returns

The number of objects being edited during this change event

GetObjectBeingEdited()

const UObject * FPropertyChangedEvent::GetObjectBeingEdited ( int32  Index ) const

inline

Gets an object being edited by this change event. Multiple objects could be edited at once

Parameters

Index

The index of the object being edited. Assumes index is valid. Call GetNumObjectsBeingEdited first to check if there are valid objects

Returns

The object being edited or nullptr if no object was found

GetPropertyName()

FName FPropertyChangedEvent::GetPropertyName ( ) const

inline

Simple utility to get the name of the property and takes care of the possible null property.

HasArchetypeInstanceChanged()

bool FPropertyChangedEvent::HasArchetypeInstanceChanged ( UObject *  InInstance ) const

inline

Test whether an archetype instance was modified. InInstance - The instance we want to know the status.

SetActiveMemberProperty()

void FPropertyChangedEvent::SetActiveMemberProperty ( FProperty *  InActiveMemberProperty )

inline

SetArrayIndexPerObject()

void FPropertyChangedEvent::SetArrayIndexPerObject ( TArrayView< const TMap< FString, int32 > >  InArrayIndices )

inline

Saves off map of array indices per object being set.

SetInstancesChanged()

template<typename T >

void FPropertyChangedEvent::SetInstancesChanged ( T &&  InInstancesChanged )

inline

Specify the set of archetype instances that were modified by the property change.

Member Data Documentation

ChangeType

EPropertyChangeType::Type FPropertyChangedEvent::ChangeType

MemberProperty

FProperty* FPropertyChangedEvent::MemberProperty

The member property of the object that PostEditChange is being called on.
For example if the property that changed is inside a struct on the object, this property is the struct property

ObjectIteratorIndex

int32 FPropertyChangedEvent::ObjectIteratorIndex

Property

FProperty* FPropertyChangedEvent::Property

The actual property that changed
