Connect the Toggle Button with a data provider

Question

In then document

Connect the Toggle Button with a data provider
https://doc.embedded-wizard.de/toggle-button-widget?v=9.20

is explained how to connect an event of a pressed button with an action without writing a line of code.

I would like instead an example of how to intercept a pressed button and do something with the code like setting high a gpio pin or display a text on the display.

Hello,

this GPIO use-case is shown in the example "DeviceIntegration" that you will find within your STM32 Build Environment within the subdirectory /Examples. This demo shows how to switch on/off the hardware LED when you press a button within a GUI application.

Please have a look to the chapter Device Class and Device Driver? It describes the necessary concepts.

Best regards,

Manfred.
