I am quite stumped. According to the documentation:
- when navigating a goup one has to use the LV_KEY_PREV and LV_KEY_NEXT keys
- when using a roller, button matrix, tabview etc. it is keys LV_KEY_LEFT etc. that are being used.
- Why is it that a button matrix behaves differently than a group? Basically: what is the difference (apart from visual and memory footprint) between a group of buttons and a button matrix?
- Why use LEFT/RIGHT instead of NEXT/PREV to navigate a roller or a tabview?
Basically: why inhibit the use of NEXT/PREV in button matrices, rollers etc.?
