Undeclared identifier "ITableRow" when trying to use SClassViewer

Development Programming & Scripting C++

When trying to use SClassViewer as so:


bool UPaperSkeletonAttachmentFactory::ConfigureProperties()
{
	AttachmentClass = nullptr;

	// Load the classviewer module to display a class picker
	FClassViewerModule& ClassViewerModule = FModuleManager::LoadModuleChecked<FClassViewerModule>("ClassViewer");

	// Fill in options
	FClassViewerInitializationOptions Options;
	Options.Mode = EClassViewerMode::ClassPicker;

	TSharedPtr<class FAttachmentClassFilter> Filter = MakeSharable(new FAttachmentClassFilter);
	Options.ClassFilter = Filter;

	Filter->AllowedChildrenOfClasses.Add(UPaperSkeletonAttachment::StaticClass());

	const FText TitleText = LOCTEXT("CreateAttachmentOptions", "Pick Attachment Class");
	UClass* ChosenClass = nullptr;
	const bool bPressedOk = SClassPickerDialog::PickClass(TitleText, Options, ChosenClass, UPaperSkeletonAttachment::StaticClass());

	if (bPressedOk)
	{
		AttachmentClass = ChosenClass;
	}

	return bPressedOk;
}

I am getting these errors when trying to build:


C:\Program Files\Unreal Engine\4.6\Engine\Source\Editor\UnrealEd\Public\Kismet2\SClassPickerDialog.h(31): error C2065: 'ITableRow' : undeclared identifier

I’ve tried including more dependencies to see if it would fix the problem to no avail.

Any help would be appreciated!

Hi,

Im using different method to get class picker but maybe it will help you, Im doing it like this:


TSharedRef<SWidget> GetClassPickerContent()
	{
		FClassViewerModule& ClassViewerModule = FModuleManager::LoadModuleChecked<FClassViewerModule>("ClassViewer");

		FClassViewerInitializationOptions Options;
		Options.Mode = EClassViewerMode::ClassPicker;
		Options.DisplayMode = EClassViewerDisplayMode::TreeView;
		Options.bIsActorsOnly = true;


		return SNew(SBox)
			.WidthOverride(350)
			.HeightOverride(500)
			
				SNew(SScrollBox)
				+ SScrollBox::Slot()
				
					ClassViewerModule.CreateClassViewer(Options, FOnClassPicked::CreateRaw(this, &STemplateTabContent::OnClassPicked))
				]
			];
			
	}

while my “includes” looks like this:


#include "ClassViewerModule.h"
#include "ClassViewerFilter.h"
#include "KismetEditorUtilities.h"
#include "SClassPickerDialog.h"
