The GUI Guider version I'm using is 2.0.0. When I'm working on Top...When adding events to a Layer, the event callback function names for the Top Layer in the generated gg_event_layer_top.c file are abnormal. Currently, a pair of parentheses is inserted in the middle of the event callback function name, like this: "static void lv_layer_top () _event_handler ( lv_event_t * e )". In fact, the same issue exists for the Bottom Layer, while Screens does not exhibit a similar problem. Hopefully, this bug can be fixed soon. Thank you!
