handleTickEvent not working with container

Hi

I've declared virtual void handleTickEvent() in the header file of my container.

In my cpp file of the container I would like to update my battery bar on every tick:

void BatteryBar::handleTickEvent()
{
 if(tickCounter >= 100)
 {
 tickCounter = 0;
 }
 UpdateBatteryBar(tickCounter++);
}

I'm not getting it to run. It never enters to handleTickEvent().

What else do I have to do to enable the tick event?

Regards

Hi @Dejan Nedeljkovic,

Only some components in TouchGFX (Like a View) are automatically subscribed to tick events. For containers, you must call this from your widget =)

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

Hello,

Can you specify where to put that line exactly? I am trying to update a graph shown in a screen that is part of a custom container and I can't find a proper way to do it. where do I write the function that updates the graph for every tick event?

Related to the question above, is there any way to change a custom container (for example change an image) from an event happened in a certain screen? I can modify any widget in a screen as lon as they are single widgets but not custom containers.

thanks in advance
