Problems extending menu for data table editor

Development Programming & Scripting

Hi

I’m currently trying to customize the data table editor in the engine code so that I can add a menu item to the ‘Asset’ drop down menu. When I run a build with the changes below the callback for the extension doesn’t get called resulting in no extra menu item.

After this in DataTableEditor.cpp:

FAssetEditorToolkit::InitAssetEditor( Mode, InitToolkitHost, FDataTableEditorModule::DataTableEditorAppIdentifier, StandaloneDefaultLayout, bCreateDefaultStandaloneMenu, bCreateDefaultToolbar, Table );

I add:

TSharedPtr MenuExtender = MakeShareable(new FExtender);
MenuExtender->AddMenuExtension("AssetEditorActions", EExtensionHook::After, GetToolkitCommands(), FMenuExtensionDelegate::CreateRaw(this, &FDataTableEditor::AddAssetMenuExtension));
AddMenuExtender(MenuExtender);

The function FDataTableEditor::AddAssetMenuExtension will add a menu section with a menu entry inside it but the function never gets called.
I’ve looked through other classes that inherit from FAssetEditorToolkit (such as Phat.cpp) to see what they do and it looks like I’m pretty much doing the same thing.
Obviously I’ve missed something.
All help will be very gratefully received!

Cheers,
Mark.

Hi Mark,

You may need to call RegenerateMenusAndToolbars() after adding your menu extension. Give that a try and let me know if your builder function still isn’t being called.

Best,

Yes that worked, thanks!
It’s worth noting that in the original code there is:

FDataTableEditorModule& DataTableEditorModule = FModuleManager::LoadModuleChecked( "DataTableEditor" );
	AddMenuExtender(DataTableEditorModule.GetMenuExtensibilityManager()->GetAllExtenders(GetToolkitCommands(), GetEditingObjects()));

At the end of FDataTableEditor::InitDataTableEditor which won’t get actioned as RegenerateMenusAndToolbars() is not getting called after it.
