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"

I cannot call OnValueChanged(...) of SNumericEntryBox


I was trying to add SNumericEntryBox to my plug-in (for now I have SButton working on).

I done it with:


I can now see the numeric entry box in my plug-in.

But when I wanted to handle value change event, adding .OnValueChanged(&Locals::numberChanged):


With following Locals structure:

     struct Locals
         static void numberChanged(int32 copies){
             OnButtonClick(FVector{ 0.0f, 0.0f, float(copies) }); //or whatever code here
         static FReply OnButtonClick(FVector InOffset){
             //that works fine for SButton

I got an compile-time error:

 error C2664: 'SNumericEntryBox<int32>::FArguments &SNumericEntryBox<int32>::FArguments::OnValueChanged(const TBaseDelegate<void,int32> &)' : cannot convert argument 1 from 'void (__cdecl *)(int32)' to 'const TBaseDelegate<void,int32> &'

Did you ever find a good solution? I am attempting the same thing and am having trouble passing in my delegate.

Try to use .OnValueChanged_Static(&Locals::numberChanged)

Protip: if youre about to create more advanced/complex UI, dont make your methods static in local struct, just take them out and put them in your main class.
