[Back] menu item

dsap4004

The back menu item in sub menus currently takes me back to the top of the entire tree instead of the top of the parent sub menu. Is this something unique to my setup or is it a feature that doesn't exist yet?

This is actually a bug that's is mainly already fixed in the next version, 1.3.1. I'd already fixed it in the display renderer while working on the extended ESP8266 support, but not got around to creating the issue for it yet. Just created now.

See https://github.com/davetcc/tcMenuLib/issues/15

Thanks,

Okay, just making sure I didn't screw something up. My screen space is limited on a 16x2 display so I changed the forward and back indicators in the library to little arrows. "?" "?"

So in version 1.3.1 there will be a configurable limit of the number levels supported in the menu structure. This is because many places use a non-recursive way of handling menu items.

The default setup would allow up to 4 levels away from root. For example:

Settings
  +--- Sub Settings I
     +--Sub Sub Settings
         +-- Sub Sub Sub
               +--- Sub Sub Sub Sub

It will be easily re-defined by opening file

MenuIterator.h

and changing the value

MAX_MENU_DEPTH

to a new value (obviously at the expense of a little memory).

I only use 2 layers at max if you don't count menu items so that will work perfectly.

1.3.1 now has the ability to set the depth required - defaulting to 4.
