[Qgis-user] show labels only, if objects are activated/visible
Hi, is it possible to show labels only, if the objects are activated/visible? I use the rule based renderer with two nested rules, both categorized rendering, like: Cat 1 # Road 1 Cat 2 ## |_ Lukas |_ Frank |_ Markus |_ Georg Road 2 |_ John |_ Leo |_ Herbert If I deactivate labeling for some values in the first categorized rendering (Cat 1), objects and labels are invisible. But if I deactivate labeling for some values in the second categorized rendering (Cat 2), objects are invisible but labels are still shown. Is there a way how to solve this in the rule based renderer? Thanks a lot Otto ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user

Hi Otto, I don't think that this is possible. As far as I know the labeling is totally disconnected from the symbology. Only global filters on the whole layer (the filter in the general tab in the layer properties) is honored by both labeling and the rest of the symbology. The rest is totally disconnected. I can see value in what you want, but I doubt it is easily possible. It would also help if we would have rule based labeling, so we could at least apply similar rules to the labels as we apply to the symbology of features. Larry probably knows more about that.

Hi Andreas, don't we have rule-based labelling? CASE WHEN THEN 'bla' ELSE 'blub' END Problem is that you may have to rewrite all the rules that you already have written in the rule-based style.

Re: [Qgis-user] show labels only, if objects are activated/visible
Hi Bernhard, Yes - we "sort of" have "rule based" labeling with the data-defined properties and conditions. But for very complex labeling it is a bit hard to track. The rules are so distributed in different places/properties that it is hard to get an overview what is really going on. I mean the UI of the rule-based symbology is nicer and allows to change multiple graphical properties of the same rule at once. There is certainly room for improvements. A coupling of rendering and labeling would be quite interesting (esp. for the case Otto is mentioning where users want to selectively enable/disable rules/categories), I think - but I don't know if it is technically solvable (or how hard it is).

Hi Andreas, I agree, the UI is much nicer and it would be great to have a similar one for the labels where you define a rule and then set text color, halo etc. for this case (and even the label text itself). Currently you have to click into data-defined properties and reenter the same rule at several places. Yes the coupling of geometry rendering and labelling would be good to have. Currently features are labeled even if the are covered by other features. No idea how much effect this would have on the rendering speed.
