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"

How can I avoid a Slate linking error - FKey?


I receive these compiler errors when trying to add an SButton to my slate contruct

 error LNK2019: unresolved external symbol "__declspec(dllimport) public: __cdecl FKey::FKey(void)" (__imp_??0FKey@@QEAA@XZ) referenced in function "private: __cdecl FReply::FReply(void)" (??0FReply@@AEAA@XZ)

here the code that uses the SButton (If I comment the block out, everything works fine btw)

                         + SHorizontalBox::Slot()
                         .Padding(15, 15, 40, 15)
                             .OnClicked(this, &SMyHelper::OnMyButtonPressed, false)
                             .Text(LOCTEXT("MyHelper", "DoSomething"))

my MyPlugin.Build.cs includes look like this

                 new string[]
                     // ... add other public dependencies that you statically link with here ...

I did add the "Slate" to the private dependencies to see if something changes but it had no effect.

Any idea what needs to be included to avoid that link error ?

Slate needs some serious documentation imho... There is way not enough simple sample usage cases available today. :(

You need a private module dependency to InputCore in your project's Build.cs file.

I solved this by adding PrivateDependencyModuleNames.AddRange(new string[] { "Slate", "SlateCore" });

to the build.cs file
