how to update wildcard in a custom container from the model?

[Jloda.11]

So I have a custom container that has a wildcard for updating time and date from an RTC.

My question is how do I update the wildcard from the model without going through each screens presenter and viewer since I have 40 screens.

Your idea isnt possible

Maybe you can create self updated component and register to tick handler

Application::getInstance()->registerTimerWidget(this);

And create

void Component::handleTickEvent()
{
if (count++==40)
    {
             count=0;
            // showed
            getrtcdata
            xxxx.show(rtc...);
    }
}
