[Qgis-developer] Composer item's IDs

[Nathan Woodrow]

Olivier,

I added the item id for that reason. Feel free to rework then so they
are auto generated and unique. That was my intention just never got
around to it.

Subject: [Qgis-developer] Composer item's IDs
Hi !

I'm developing a plugin which needs to attach some custom data to some
Composer Item's instances.
Thus, I need a way to identify the instances.

I saw that there's an ID attribute in the ComposerItems, but don't
really know how it's supposed to work. It seems for now it's only an
user defined value, which remains empty when the user doesn't provide
it and which also can be duplicated.
So it seems I can't use this as an unique ID.

What's the best way to do that ?


More globally, what is this ID good for ? Is it's behavior not fully
implemented yet ?

I think it would be useful to auto-assign unique which the user
couldn't change. If needed, another attribute ("name" or "tag") could
be added to replace the current "ID" behaviour, allowing the user to
define custom data.

What do you think ?

Thanks !!

Olivier
