I can’t figure out how to actually retrieve which key was pressed in an event callback.
Specifically, I’m using a roller callback, and I get the events like
However, the callback signature of the even callback system has no means of passing in the actual event data. How do I retrieve that?
I see in
lv_event_send_func that the input device’s callback gets the data at
indev_act->driver.feedback_cb, but I don’t quite see the use of that – isn’t it the indev that sent the key in the first place?
What MCU/Processor/Board and compiler are you using?
What LVGL version are you using?
github master branch
What do you want to achieve?
Get the key value so that I can pop out of a menu when a particular key is pressed.
What have you tried so far?
looked through the code and I can’t find how I’m supposed to retrieve the actual key pressed value.
