Re: Fwd: Re: [Qgis-developer] Wiki page: switching from old to new symbology, missing bits
Hi Andreas, Nice to hear about the SQL in labeling, that would be a great thing. Regarding the grouping. The feature now implemented is not quite what I meant. Now you can group by filter or by scale, I meant that you should be able to apply two filters in a row. I understand that this might be a bit tricky to program, but it would be quite nice. I know that one can achieve the same with the SQL AND today, but this way you get very many filters (# categories in filter 1 times # categories in filter 2) which is inconvenient for the user.

Currently I am doing this in a Postgis view. Given that we already have the field calculator one could re-use this functionality for this purpose. Rule-based renderer and hierarchies: I believe this is already possible with the filter grouping. There is group by scale or group by filter. Does this satisfy your needs? Please go ahead and modify the wiki, but also don't forget to open a feature request. If you do a feature request in the bug tracker you can add the corresponding link to the wiki.

Re: [Qgis-developer] Wiki page: switching from old to new symbology, missing bits
Hi Andreas, I proposed significant additions to the Rule based Renderer in a patch here: http://trac.osgeo.org/qgis/ticket/3222 http://trac.osgeo.org/qgis/attachment/ticket/3222/rule_renderer_patch_on_r15004-symbols_not_merged.diff Applying this patch would solve several issues, including one you mentioned: Needs alias columns for the legend. I just tried to write this on http://www.qgis.org/wiki/ but when I try to create an account, I receive the answer: You do not have permission to create this user account, for the following reason: The action you have requested is limited to users in the group: Administrators. I also have several comments and ideas for the Rule based Renderer, based on tests to create multiscale world map with OSM data.
