Issue with adding button in code. Am I doing this right?

Hello!

I am trying to add a button to my application manually through code. I thought it would be quite simple, but for some reason I am having some difficulties.

I have added it my screenView class, and initialised it using bitmapped images from the TouchGFX library.

It displays on screen correctly, but does not respond to any touches. I would expect at this point for the image on screen to change when I press it.

I have added other buttons from the designer, that are responding correctly.

Does anyone have any idea what I am doing wrong? Is there something I am not initialising correctly that links the button to TouchGFX engine?

I'm embarrassed to say that this has stumped me for several hours now!

Thank you.
