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"

Discarding property changes?


have a class (deriving from AActor) which makes use of PostEditChangeChainProperty to keep up with changes made to a TArray of objects in the editor. As nice as this is, I also need a way to discard changes made this way BEFORE my data has actually been changed, and possibly even a way to revert the details panel to it's prior state, letting users know that such a change is not allowed.

I took a look around and found the PropagatePreEditChange and PropagatePostEditChange methods. After reviewing the source code, it would seem that these methods are exactly what I'm looking for, but I can't seem to find a way to override or implement them into my class. The original method definitions aren't marked as virtual, and in UObject.h it comments Non virtual functions, not intended to be overridden above them. Google was useless in researching these methods, so it appears I'm at a loss with them.

I also noticed PreEditChange, which is actually called from PropagatePreEditChange. The issue I find with this method is that it only seems to notify you when a property is about to change, but doesn't seem to provide a way to prevent or revert changes. I'm assuming that PreEditUndo is tied to this, but I can't find enough information.

Question (TL;DR)

o, does anyone know the proper way to monitor and revert property changes made to an array in the editor details panel?
