Switch

Switch states in a column

Four switches covering the default, checked, disabled, and checked-disabled states.

The active screen is set to LV_FLEX_FLOW_COLUMN with centered flex alignment and holds four switches: a default one with LV_OBJ_FLAG_EVENT_BUBBLE set, a LV_STATE_CHECKED switch, a LV_STATE_DISABLED switch, and one with both states combined. Each one subscribes to LV_EVENT_ALL and logs On or Off on LV_EVENT_VALUE_CHANGED based on lv_obj_has_state(..., LV_STATE_CHECKED).

Vertical switch orientation

Two 30 x 60 switches, one horizontal and one forced to vertical orientation.

The active screen is laid out as LV_FLEX_FLOW_ROW with centered flex alignment. Both switches are sized 30 x 60 so one is taller than it is wide; the first keeps the default orientation while the second calls lv_switch_set_orientation(..., LV_SWITCH_ORIENTATION_VERTICAL) and starts in LV_STATE_CHECKED. A shared callback logs On or Off on LV_EVENT_VALUE_CHANGED.
