I don't want to show the leading zeros of the lv_spinbox

How-to
1

Hi, Master
Version : LVGL v9.1
Problem :
I want to disable leading zeros in lv_spinbox . For example, when the spinbox display range is 0.0~999.9 , the integer part has a dynamic number of digits. Currently, using lv_spinbox_set_digit_format(spinbox, 4, 3); displays unnecessary leading zeros (e.g., 005.6 ). I want it to show only the truly significant digits in the integer part (e.g., 5.6 ).
Thanks

You can add something like this:

lv_spinbox_add_event_cb( spinbox, spinbox_value_changed_cb, LV_EVENT_VALUE_CHANGED, NULL );

void spinbox_value_changed_cb( lv_event_t* e ) 
{
    lv_obj_t* spinbox = lv_event_get_target_obj( e );
    int32_t value = lv_spinbox_get_value( spinbox );

    if ( value >= 0 && value <= 9 )
    {       
        lv_spinbox_set_digit_format(spinbox, 2, 1);
        return;
    }
    else if ( value >= 10 && value <= 99 )
    {       
        lv_spinbox_set_digit_format(spinbox, 3, 2);
        return;
    }
    else if ( value >= 100 && value <= 999 )
    {       
        lv_spinbox_set_digit_format(spinbox, 4, 3);
        return;
    }
}

OK, Thank you very much.
