Change TileView Scroll animation speed

[jgauchia]

LVGL version

v9.1.0

What happened?

As described in this post scroll animation speed of a tileview is fixed by "define" constant in lv_obj_scroll.c

#define SCROLL_ANIM_TIME_MIN    200    /*ms*/
#define SCROLL_ANIM_TIME_MAX    400    /*ms*/

There are any "possibility" to add a public method or similar in order to change the scroll animation time?

Thank you!

How to reproduce?

Hi,

You can do this to modify the scroll animation:

void anim_start_event_cb(lv_event_t * e)
{
	lv_anim_t * a = lv_event_get_param(e);
	if(a) a->duration = 2000;
}

...

    lv_obj_t * tv = lv_tileview_create(lv_screen_active());
    lv_obj_add_event_cb(tv, anim_start_event_cb, LV_EVENT_SCROLL_BEGIN, NULL);
