WebKit2.WebContext.prototype.set_spell_checking_languages

function set_spell_checking_languages(languages: Array(String)): void {
    // Gjs wrapper for webkit_web_context_set_spell_checking_languages()
}
  

Set the list of spell checking languages to be used for spell checking.

The locale string typically is in the form lang_COUNTRY, where lang is an ISO-639 language code, and COUNTRY is an ISO-3166 country code. For instance, sv_FI for Swedish as written in Finland or pt_BR for Portuguese as written in Brazil.

You need to call this function with a valid list of languages at least once in order to properly enable the spell checking feature in WebKit.
