void *lv_xml_create(lv_obj_t *parent, const char *name, const char **attrs)

void *lv_xml_create_in_scope(lv_obj_t *parent, lv_xml_component_scope_t *parent_ctx, lv_xml_component_scope_t *scope, const char **attrs)

void lv_xml_set_default_asset_path(const char *path_prefix)

Set a path to prefix the image and font file source paths.

In globals.xml usually the source path is like "images/logo.png". But on the actual device it can be located at e.g. "A:ui/assets/images/logo.png". By setting "A:ui/assets/" the path set in the XML files will be prefixed accordingly.

Parameters:

path_prefix – the path to be used as prefix
