More indepth guide on programming TouchGFX?

[Tnguy.3]

Hey guys,

So, I'm taking on a project that will use STM32H7 chip with a TFT panel screen (with touch capabilities) on a custom PCB. The project is a custom gauge (like a speedometer) that allow user inputs via the touch display. So my question is, does anyone know where I can learn more about programming the UI using the touchGFX (after setting up the base UI using the application).

My main interest

• Learning more about the refresh/tick function that updates the gui (the documents wasn't very clear), like how to call/modify it to call custom functions.
• How to add (and effective way to doing it) tap, tap n hold, and drag function to (any) element on the screen or just any section of the screen.
• How to add event handlers to elements (e.g when something before unfocused)

Thanks,
