Update flex button from a view to custom container

[matheuschiarelli]

Hello!

I've been having some problems to update a flex button inside a custom container that i created and used as template in a scroll list.

My goal is: select an item in scroll list by hardware button, and change the state of a flex button from "Released" to "Pressed" and vice-versa.

Issue: the function that i use to update the items only update when the scroll movement is made, create another function to send the button's update command to the container didn't work.

I need to update the button state immediatly with a button click, how can i do this? 

My code:

//My container

void RoutingContainer::setListElements(int item) { //Function to define items in scroll list
	switch (item) {
	case 0:
		channel_number.setTypedText(TypedText(T_RESOURCEID1));
		break;
	case 1:
		channel_number.setTypedText(TypedText(T_RESOURCEID2));
		break;
	case 2:
		channel_number.setTypedText(TypedText(T_RESOURCEID3));
		break;
	case 3:
		channel_number.setTypedText(TypedText(T_RESOURCEID4));
		break;
	case 4:
		channel_number.setTypedText(TypedText(T_RESOURCEID5));
		break;
	case 5:
		channel_number.setTypedText(TypedText(T_RESOURCEID6));
		break;
	case 6:
		channel_number.setTypedText(TypedText(T_RESOURCEID7));
		break;
	case 7:
		channel_number.setTypedText(TypedText(T_RESOURCEID8));
		break;
	}
}

void RoutingContainer::setButtonState(bool pressed) //Function to change the buttons state
{
    btn_left.setPressed(pressed);
    btn_left.invalidate();
}

//View


//This function only updates when the scroll is made,  and it's the only way i can update the widgets (i guess)

void routing_channelView::scrollList1UpdateItem(RoutingContainer& item, int16_t itemIndex)
{
    item.setListElements(itemIndex);

    if (itemSelected && (itemIndex == listIndex))
    {
        item.setButtonState(true);
    }
    else
    {
        item.setButtonState(false);
    }

}

void routing_channelView::selectOption()
{
	itemSelected = true;
}
