Good day.
I need to make a menu for selecting an actor component on a level. I found how to do it, but the search bar doesn’t work quite as I expect.
Right now it seems to only show components that match the name, but only if the actor’s name also matches the search criteria.
This is how I create a scene outliner:
FSceneOutlinerInitializationOptions Options;
Options.bFocusSearchBoxWhenOpened = true;
FComponentsFilter* Filter = new FComponentsFilter(GetFilterValue(StructPropertyHandle));
SceneOutlinerFilter = MakeShareable(Filter);
Options.Filters->Add(SceneOutlinerFilter);
Options.ModeFactory.BindLambda([](SSceneOutliner* Outliner)
{
FActorModeParams Params;
FActorMode* Mode = new FActorMode(Params);
return Mode;
});
FSceneOutlinerModule& SceneOutlinerModule = FModuleManager::Get().LoadModuleChecked<FSceneOutlinerModule>(TEXT("SceneOutliner"));
SceneOutliner = SceneOutlinerModule.CreateComponentPicker(Options, FOnComponentPicked::CreateLambda([this, StructPropertyHandle](UActorComponent* PickedComponent) { /*some actions*/}));
FComponentsFilter.h:
class FComponentsFilter : public FSceneOutlinerFilter
{
public:
FComponentsFilter(TSubclassOf<UActorComponent> InFilterComponentClass) : FSceneOutlinerFilter(EDefaultBehaviour::Pass)
{
FilterComponentClass = InFilterComponentClass;
}
TSubclassOf<UActorComponent> FilterComponentClass;
virtual bool PassesFilter(const ISceneOutlinerTreeItem& InItem) const override;
};
FComponentsFilter.cpp:
bool FComponentsFilter::PassesFilter(const ISceneOutlinerTreeItem& InItem) const
{
if (!FilterComponentClass)
{
return false;
}
const FActorTreeItem& ActorItem = static_cast<const FActorTreeItem&>(InItem);
if (ActorItem.Actor->GetClass()->IsChildOf(FilterComponentClass) || ActorItem.Actor->GetClass()->IsChildOf(AActor::StaticClass()))
{
return true;
}
return false;
}
How can I make it so that the actor name is ignored, filtering occurs only by component name, and actors are displayed only if their component matches the search criteria?
Thanks in advance.
