如果需要调整控件的尺寸,可以使用函数,lv_obj_set_width()和lv_obj_set_height()分别调整长宽,或使用lv_obj_set_size()一并调整: lv_obj_t* cont =lv_obj_create(lv_scr_act());lv_obj_t* label =lv_label_create(cont);lv_label_set_text(label,"Helllllo, world!");lv_obj_set_size(cont,16...
contanier1= lv_obj_create(lv_scr_act()); lv_obj_set_size(contanier1,320,240);//设置容器大小 lv_obj_set_style_radius(contanier1,0,0);//设置容器圆角为直角 contanier2= lv_obj_create(lv_scr_act()); lv_obj_set_size(contanier2,320,240); lv_obj_set_style_radius(contanier2,0,...
lv_obj_align(ta, LV_ALIGN_TOP_MID,0,10);// 相对位置设置 lv_obj_set_size(ta, lv_pct(90),80);// 文本框大小 lv_textarea_set_placeholder_text(ta,"Click Enter");// 文本提示信息 lv_obj_add_state(ta, LV_STATE_DEFAULT);// 设置文本框为默认状态 /* 文本控件的所有事件*/ lv_obj_ad...
