Description

I am trying to create a label-only layer to show labels on another layer. However, if there are no styles shown, then the labels will not be drawn.

[FEATURE] Null ("No symbol") renderer

Using this renderer no symbol will be drawn for features, but labeling,
diagrams and other non-symbol parts will still be shown.

Selections can still be made on the layer in the canvas and selected
features will be rendered with a default symbol. Features being edited
will also be shown.

This is intended as a handy shortcut for layers which you only want
to show labels or diagrams for, and avoids the need to render
symbols with totally transparent fill/border to achieve this.

(fix #12131)

you are probably doing it wrong, see for example this

please reopen if necessary. Cheers!

Although a low priority, I think this is a valid use case, primarily as creating discrete label-only classes is very useful at times (especially given you cannot create label classes right now).

this is not related to the subject/description of this ticket(?). Seems more a different thing (a feature request), while you can certainly create layers with "no" symbology and use them as markers to pinpoint labels for other layers. Please leave feedback.

You are correct, however you have to create an empty symbology and then set it is any version of blank. Ideally, I would change the dropdown with "Single Symbol", etc. to have "No symbology" at the bottom, to make it easy to make a label-only layer.

this is a good suggestion, but how it relates to this ticket title/description?

#6 Updated by Corey Burger about 9 years ago

Sorry, that was a suggested implementation to the problem of needing to have a symbology defined for labels to show.

I agree this would be a handy thing to have. I have updated the ticket information. Nyall and I have talked about it in the past I don't recall there being a reason we couldn't do it.
