Version 2 issues: C code generation, preview

poldo — Fri, 10 Jul 2026 15:40:14 GMT

Hi!

I started testing GUI Guider version 2, and I found a couple of issues (starting with an empty template, Windows simulator).

I started defining the content of the top layer putting an image button, creating an event handler to switch state when the button is long pressed.

The generated the code has some errors, like:

gg_event_layer_top.c:
static void lv_layer_top()_event_handler(lv_event_t * e) {
...
}

void gg_event_init_layer_top(gg_ui_t * ui

lv_obj_add_event_cb(ui->layer_top.lv_layer_top(), lv_layer_top()_event_handler, LV_EVENT_ALL, ui);

(parenthesis create a parsing error)

Manually removing the parenthesis, the error below is generated:

.../generated/events/gg_event_layer_top.c:59:38: error: 'gg_layer_top_t' has no member named 'lv_layer_top'

(gg_layer_top_t definition doesn't include that member)

Am I missing some definition to make a correct generation of those functions?

Hi @Harry_Zhang , thank you for your reply.

This is what I did:

- On layer_top (clickable flag added, is this necessary?) I created a container for my buttons (no clickable flag added)
- Inside the container I created an image button (clickable flag added)
- I attached the event "Long Pressed" to the button

Generated code contains the syntax errors above.

// In gg_event_layer_top.c static void lv_layer_top()_event_handler(lv_event_t * e) { gg_ui_t * ui = lv_event_get_user_data(e); lv_event_code_t code = lv_event_get_code(e); switch(code) { default: break; } } void gg_event_init_layer_top(gg_ui_t * ui) { lv_obj_add_event_cb(ui->layer_top.lv_layer_top(), lv_layer_top()_event_handler, LV_EVENT_ALL, ui); lv_obj_add_event_cb(ui->layer_top.Keypad_btnEnable, Keypad_btnEnable_event_handler, LV_EVENT_ALL, ui); }

Removing the parenthesis the syntax error is about the member lv_layer_top not existing:

// In custom.h typedef struct { lv_obj_t * Keypad; lv_obj_t * Keypad_btnEnable; } gg_layer_top_t;

Hi @poldo

I tried to reproduce this issue.

The generated code is correct.

May I ask what I missed?

Hi @Harry_Zhang .

The issue is when you create objects on the top layr. I'm attaching my file for your review and test.
