Thanks! I tried this so far:
    private void letButtonsFlash(){
        foreach(Button btn;bArr){
            btn.setSensitive(false);
        }
        for(int i = 0; i < level; i++){
            Button currentButton = bArr[rndButtonBlink[i]];
            ListG list = 
currentButton.getStyleContext().listClasses();
            string CSSClassName = 
to!string(cast(char*)list.next().data);
            currentButton.getStyleContext().addClass(CSSClassName 
~ "-flash");
            writeln(CSSClassName);
            Timeout t = new Timeout(&timeout_delay,1,true);
            
currentButton.getStyleContext().removeClass(CSSClassName ~ 
"-flash");

        }
        foreach(Button btn;bArr){
            btn.setSensitive(true);
        }
    }
    bool timeout_delay(){
        Thread.sleep(dur!("seconds")(5));
        return false;
    }

and it is "working" to the extend that at least the CSSClassName 
gets written in the console but the UI again just pops up after 5 
sec. Could you give me a tip?
