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"

[C++]Widgets and Force Garbage Collector

Hi everybody! I'm working with widgets in C++ and I'm testing the garbage collector of the Engine. My scenario is that I've a pointer to a widget instance, at a certain point I need to destroy the widget: for what I've experienced, the best way is to detach all pointers to the widget, in such a way to allow the garbage collector to destroy it. Since a don't want to waste resources and speed up the deletion of the widget I'm making these calls:

 MyWidget->ConditionalBeginDestroy();
 MyWidget= nullptr; 
 GetWorld()->ForceGarbageCollection(true);

In this way the garbage collector destroys immediatly the old widget. My question is: is safe to use these function methods?? How does "ConditinalBeginDestroy()" exactly work?

Thanks!
