I’m following the LVLG book and related examples and I have a question about lv_obj_remove_style_all() function.
In chapter 2.4 you say to call lv_obj_remove_style_all to remove default styles, before apply the custom one to the button.
But in chapter 2.5 the same is not required before assign custom styles to the Slider.
Commenting out the new style I can see the slider with default style, so it exists.
So, why and when removing default style is actually required?
Thanks so much

Hi.
Thanks for pointing that out.
We were mistaken… that function removes previously applied styles.
So, you must use it to remove any styles that you might have added previously. So, you don’t need it if applying your own styles for the first time in that program.
Regards.
