Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Do I need to explicitly trash Slate brushes when my widget destructs?

Heya! I have a UWidget class where I overrode the RebuildWidget() function to do some SImage drawing. In the constructor, I create a bunch of UTexture2D and FSlateBrush. My question is: do I need to delete these myself in a destructor, or are they handled automatically?

Member vars:

     TArray<UTexture2D*> TallyImages;
 
     TArray<FSlateBrush*> TallyBrushes;

Constructor:

 UTallyPageUI::UTallyPageUI()
 {
 
     ConstructorHelpers::FObjectFinder<UTexture2D> Tally1Ref(TEXT("Texture2D'/Game/2DSideScrollerAssets/Textures/UI/Tally/Tally1'"));
     TallyImages.Add(Tally1Ref.Object);
     TallyBrushes.Add(new FSlateDynamicImageBrush(TallyImages[0], FVector2D(48, 46), FName("Tally1")));
 
     ...4 more of the above block with different numbers
 }

No, GC only cleans UObject so you need to destroy them with delete.... but you don't need to dynamically create them with "new", they are structs and made to declere then statically, then they will go out with object
