A typical solution would be something like this:

constructor() {
    const _self = this;
    this.articlesListBox.addEventHandler(new class implements EventHandler {
        handle(): void {
           _self.articleSelected(); 
        }
    });
}

You should use a syntax-correct word. Please use `something` rather than `smth`. – SuperStar518 Jun 13 '21 at 06:01
