UE-87321

Map container which has struct type value might be displayed inside unnecessary hierarchy

Map container which has struct type value might be displayed inside unnecessary hierarchy

UDN
Description

Essentially, A bug in --[Link Removed]-- comes up with only customized struct property.
If a struct doesn't have customization, it can be displayed compact without "Element X" node hierarchy.
It is the same as UE4.23 behavior.
I write a code for it.

bool FDetailPropertyRow::NeedsKeyNode(TSharedRef<FPropertyNode> InPropertyNode, TSharedRef<FDetailCategoryImpl> InParentCategory)
{
	UStructProperty* KeyStructProp = Cast<UStructProperty>(InPropertyNode->GetPropertyKeyNode()->GetProperty());
	UStructProperty* ValueStructProp = Cast<UStructProperty>(InPropertyNode->GetProperty());
	return KeyStructProp != nullptr || GetPropertyCustomization(InPropertyNode->GetPropertyKeyNode().ToSharedRef(), InParentCategory).IsValid() ||
		( ValueStructProp != nullptr && GetPropertyCustomization(InPropertyNode, InParentCategory).IsValid() );
}

After

Steps to Reproduce
  1. Create Blueprint
  2. Add Integer variable
  3. Change the variable to a Map
  4. Set the Value type to BoxShpereBounds
  5. Compile
  6. open Class Defaults pane
  7. Add an element to the variable

RESULT

Map which has structure type value always places inside "Element X" node.
