[Qgis-developer] No symbol renderer... thoughts?
Hi all, I find I'm often adding layers to a map solely for labelling, and having to set the symbology for these layers to a 100% transparent symbol so that the features themselves aren't shown. This seems rather hacky and inefficient, since QGIS is still rendering these feature, they just aren't being shown. Consequently, I'd like to add a better method for having layers with no visible features. As far as I can see, there's three possible options for this: - Add a no symbols renderer. - Allow the first symbol layer to be removed, so that a symbol can have no layers - Add no fill/no line/no marker symbol layers What would be the preferred solution, from a design and UX view? I'm leaning toward the no symbols renderer option myself, but thought I'd seek feedback before digging into this.

Hi, I like the idea of the no symbols renderer. Probably the easiest of the proposed solutions for the user.

Re: [Qgis-developer] No symbol renderer... thoughts?
I'd vote for the last option as it'd be compatible with rule based symbology, which could be useful when coupled with the [x] show layer count (simple eg creating a ELSE rule with a no-symbol layer to keep track of nb of features not rendered.).

Re: [Qgis-developer] No symbol renderer... thoughts?
Hi, excellent idea if we get speed improvement ! I don't have QGIS running here right now, but I remember having seen a no symbol checkbox in rule based renderer. If we look for consistant UI, we should have the same checkbox for classical renderers on symbol level. I remember being puzzled when I discovered that and didn't find it in classical symbology. I my experience, users didn't discover displacement point renderer by themselves, because it's the lowest entry in the listbox. I suspect we can expect low usage of no symbol renderer if we put it there.

You can already have no symbol for a rule. Just untick the Symbol checkbox in the rule properties. - Nathan On Tue, Jul 1, 2014 at 12:32 AM, Mathieu Pellerin nirvn.a...@gmail.com wrote: I'd vote for the last option as it'd be compatible with rule based symbology, which could be useful when coupled with the [x] show layer count (simple eg creating a ELSE rule with a no-symbol layer to keep track of nb of features not rendered.).

Ahh, one learns everyday. When checked, are the labels still drawn?
