然后就可以将样式分配给控件,例如,以下创建了一个按钮并利用lv_obj_add_style()函数设置其样式为刚才创建的样式了: lv_obj_t* btn = lv_btn_create(lv_scr_act()); lv_obj_set_size(btn, 120, 50); lv_obj_t* label = lv_label_create(btn); lv_label_set_text(label, "Button"); lv_obj_a...

同样的,也可以用lv_style_init初始化一个style,然后lv_style_set_prop添加style,再lv_obj_add_style给控件添加style。

Here are some examples to set an object's size using a style: ```c static lv_style_t style; lv_style_init(&style); lv_style_set_width(&style, 100); lv_obj_t * btn = lv_btn_create(lv_scr_act()); lv_obj_add_style(btn, &style, LV_PART_MAIN); ``` As you will see bel...
