Child objects block clickability of parent object

[kdw2060]

Hi,

not sure if this is a bug so posting a question here first.

I have a parent object with 2 children looking like this:

{"id":20,"obj":"obj","x":220,"y":100,"w":190,"h":160,"click": true,"radius":10,"bg_color":"#1abd23","border_color":"#000000","bg_grad_dir":0}
{"id":21,"obj":"img","parentid":20,"x":54,"y":18,"src":"L:/kodi.png","pivot_x":0,"pivot_y":0,"zoom":90}
{"id":22,"obj":"label","parentid":20,"x":30,"y":115,"text":"Kodi kijken","text_font":"ubuntu28"}

and on the Home Assistant side this action associated with he parent object:

- obj: "p2b20" ##Test met Kodi-knop
      event:
        "up":
          - service: switch.toggle
            target: 
              entity_id: switch.plug_tuinverlichting
            data: {}

Now I presume the whole p2b20 object to be clickable and execute the action, but I notice I need to tap a corner. If I tap an area where the child objects are located nothing happens.
Already tried to add "click":true to the child objects but that does not help.
I could off course repeat the action for all 3 objects, but that would seem to me like adding unnecessary bloat to the code.

So is this normal behaviour? Or am I making a mistake in my code? Or is this a bug?

I believe this is called event-bubbling which is only available in LVGL 8.0 or later.
openHASP uses LVGL 7.11, so I'm affraid this can't be easily fixed, without duplicating the yaml code...

Thanks for clarifying. I'll work around that limit then for now.
Out of curiosity: do you have plans to upgrade the LVGL library that's used by openHASP?

[fvanroie]

That requires a very substantial rewrite of a bunch of code. I've open sourced the code, so anyone can pitch in.
Is this something you want to contribute towards?

Alas, I'm not versed in C++ so cannot help with that. The only thing I could be contributing to is the frontend of the firmware if it were nodejs/javascript based (and found the time for, which is another question altogether).
