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"

Listening to event from child UMG BP to parent UMG BP


I would like to listen to an event that is broadcasted from my custom widget. I would like to do this in the same way that I can listen to the OnClicked event from a UButton widget. I believe I have set it up correctly, but the listening blueprint never receives the event. I have set it up as follows.

UserInterfaceMainBP contains my custom widget TabletBP. TableBP inherits from my UUserWidget called UTableWidget.

UTableWidget broadcasts an event OnRowSelected via c++.

void UTableWidget::RowSelected( OProperties* pProperties ) { m_pPropertiesProxy->SetProperties( pProperties ); OnRowSelected.Broadcast( m_pPropertiesProxy ); }

So far everything works up to here. The event gets broadcasted and TabletBP receives it.

However, if UserInterfaceMainBP binds to the TableBP OnRowSelected delegate, then UserInterfaceMainBP never receives it.

I've also tried creating a custom Event Dispatcher via the TableBP. This also did not work.

Is it possible for a parent UMG blueprint to listen to an event sent from one of its child UMG blueprints?

Product Version: UE 4.13
