Containers with buttons; screen with container; change button color in screen.setup()

[Roger.ch]

TouchGFX 4.21

I have defined a user container: "Selection".

The container contains two buttons: switchToScreenOne and switchToScreenTwo.

I have also defined an interaction for each button that changes the screen.

I have defined two screens: One, Two.

Both screens contain the container "Selection1"

The process works fine.

Question: How can I set the color of the buttons in the containers in the ScreenOneView::setupScreen() function?

I have already tried everything and just can't find the solution.

Simply create method in container

THX. That works. But it is still very cumbersome. :(

Why normal C++ objects in class is private = cant manipulate outside class.
