I'm developing a Trados plugin and about Termbases function now watching below.

http://producthelp.sdl.com/SDK/TerminologyProviderApi/2017/html/ea58dcf0-67b3-4a5a-9112-4300bde2b933.htm

I would like to add "Add New term" function for my addin.

But "Add New Term" button on Trados is inactive for my plugin.

What are needed for this?

================================

Are there any relation with "GetLanguages" method?

public override IList<ILanguage> GetLanguages()
{
List<ILanguage> list_lang = new List<ILanguage>();
list_lang.Add((ILanguage)new DefinitionLanguage()
{
Name = "Japanese"
Locale = new CultureInfo("ja")
});
list_lang.Add((ILanguage)new DefinitionLanguage()
{
Name = "English"
Locale = new CultureInfo("en")
});
return list_lang;
}
