/**
|
|
* @title Slider indicator part and pressed state
|
|
* @brief Style a slider's indicator differently when it is pressed.
|
|
*
|
|
* One style gives the slider's `LV_PART_INDICATOR` a horizontal red
|
|
* gradient, and a second style adds a red shadow with `shadow_width = 10`
|
|
* and `shadow_spread = 3` on `LV_PART_INDICATOR | LV_STATE_PRESSED`. The
|
|
* slider is created with value 70 and centered on the active screen, so
|
|
* pressing the indicator reveals the shadow.
