1 I can’t get the title pointer of “obj_win” or"obj_tabview"" and I want to set its size.
The default title is too high and takes up a lot of space.
2 I want to create a universal exit button
I get the parent pointer of the incoming parameter btn, which I set to nullptr, but in fact the parent pointer does not point to nullptr. I have a std:: array < lv_obj_t*> obj to manage all my pages and he will judge obj== nullptr to call the lv_obj_del() function.
