Hello @Community member​ ,

Did you use interactions ?

On the screenshot attached, you can see on the top-right corner of the screen the "Interactions" menu.

There you can select the source (button in your case) of your interaction, and the action you want to execute after the event was triggered (change screen, hide widget, ..).

If you want to do something more complex after clicking your button than one of the actions I listed above, I will have to select the "execute C++ code" option. Then, in your ScreenView.cpp, you can use API functions to do what you want.

You can take a look at this article to understand better how it works. I also advice you to read the whole documentation of TouchGFX.

Hope this helps,
