You can set the position relative to the parent with lv_obj_set_x(obj, new_x) and lv_obj_set_y(obj, new_y), or both axes at the same time with lv_obj_set_pos(obj, new_x, new_y). Alignment ¶ You can align the object on its parent with lv_obj_set_align(obj, LV_ALIGN_.) .lv style obj tGet the actually set y coordinate of object, i.e. the offset from the set alignment. int32_t lv_obj_get_width(const lv_obj_t *obj) int32_t lv_obj_get_height(const lv_obj_t *obj) int32_t lv_obj_get_content_width(const lv_obj_t *obj) Get the width reduced by the left and right padding and the border width.
bool lv_obj_check_type (const lv_obj_t * obj, const lv_obj_class_t * class_p) ¶ Get object's and its ancestors type. Put their name in type_buf starting with the current type. E.g. buf.type[0]="lv_btn", buf.type[1]="lv_cont", buf.type[2]="lv_obj"LV_ALIGN_CENTER. It's quite common to align a child to the center of its parent, therefore a dedicated function exists: lv_obj_center(obj); //Has the same effect lv_obj_align(obj, LV_ALIGN_CENTER, 0, 0); If the parent's size changes, the set alignment and position of the children is updated automatically.Overview.

Unlike in CSS, LVGL local styles can be assigned to states (pseudo-classes) and parts (pseudo-elements). To set a local property use functions like lv_obj_set_style_(obj, , ); For example: lv_obj_set_style_bg_color(slider, lv_color_red(), LV_PART_INDICATOR | .You can set a new parent for an object with lv_obj_set_parent(obj, new_parent). To get the current parent, use lv_obj_get_parent(obj). To get the children of an object, use lv_obj_get_child(obj, child_prev) (from last to first) or lv_obj_get_child_back(obj, child_prev) (from first to last).void lv_img_set_offset_x (lv_obj_t * obj, lv_coord_t x) ¶ Set an offset for the source of an image so the image will be displayed from the new origin.
