Miscs

PropertyHandle

PropertyHandle in CustomizeHeader and CustomizeChildren is always the root property (for example, your struct).

Get/Set property

This works if the property has a Edit specifier

TSharedPtr<IPropertyHandle> SelectedSocketProp = PropertyHandle->GetChildHandle(GET_MEMBER_NAME_CHECKED(FFUPickerSockets, SelectedSocket));  
 
// Get
FName SelectedSocket;  
SelectedSocketProp->GetValue(SelectedSocket);
 
// Set 
SelectedSocketProp->SetValue(FName("NewValue"));

CustomizeChildren

This will construct default child members for the member props of your type details customization.

// Thanks to aquanox for the snippet
void FCustomization::CustomizeChildren(TSharedRef<IPropertyHandle> PropertyHandle, IDetailChildrenBuilder& ChildBuilder, IPropertyTypeCustomizationUtils& CustomizationUtils)  
{  
    uint32 NumberOfChild = 0;  
    if (PropertyHandle->GetNumChildren(NumberOfChild) == FPropertyAccess::Success)
    {
	    for (uint32 Index = 0; Index < NumberOfChild; ++Index)  
       {
	       TSharedRef<IPropertyHandle> ChildPropertyHandle = PropertyHandle->GetChildHandle(Index).ToSharedRef();  
          ChildBuilder.AddProperty(ChildPropertyHandle);  
       }
    }
}
