number of pages

[nagyrobi]

A quick note: numPages in statusupdate is always 12, while I only defined 5 pages in my .jsonl file.

[fvanroie]

yes, esp32 always has 12 pages

[nagyrobi]

I thought numPages would reflect the number of configured pages (aka. pages with at least 1 object on them).
Would be useful to prevent switching to empty pages when keep pressing next.

If numPages busy, could implement another variable for this, in statusupdate.

[fvanroie]

numPages reflects the maximum number of pages (aka. the maximum number of the last page).

hasp-lvgl has no concept of an empty page. All pages exist at all times and are available to create/delete objects whether you use them or not.

It would be nice to differentiate somehow the pages containing meaningful objects, so that the end-user should not be presented with a page containing irrelevant objects or no objects at all (=empty).

I thought this could be known automatically just by looking at the "page" property of all the objects, and take the highest number from there, which would be helpful on the HA side. That's all.

You can now get/set the following attributes on a page object (e.g. p1b0):

• prev : The number of the destination page when performing a page prev action on this page
• next : The number of the destination page when performing a page next action on this page
• back : The number of the destination page when performing a page back action on this page

By default all pages cycle in a round-robbing fashion, but you can change this behaviour by adjusting the prev, next and back target pages:

p1b0.prev=5    // go to page 5 instead of page 12
p5b0.next=1    // start back from page 1

This will cycle through page 1-5 only. back acts like a * level up* action, so you can jump back to the home or menu page where you came from using page back.

How can this be set from jsonl?

[nagyrobi]

@dgomes also CC support has to be added as currently the component calls pages directly by number when next/prev

[dgomes]

if the firmware handles this I can remove page control altogether :)

[fvanroie]

How can this be set from jsonl?

jsonl

{"page":1,"id":0,"next":1,"prev":5,"back":3,"bg_color":"black"}

[fvanroie]

This was implemented in 0.5.0

Works, thanks
