Re: [Qgis-user] Multiple Symbolization Rules per Layer
Hi Agus, while I agree that your suggestion makes sense and would help for many purposes, in my case it wouldn't help. What I wanted to do is to style line elements according to three different attributes. In my case I have to handle the waste-water network. * Attribute Utility should define the line-color * Attribute accuracy should define stroke-dashing * Attribute hierarchical_function should define stroke-width You cannot solve this problem through multiple loading of the same layer. The only current way is by concatenating the three attributes into a single attribute and than style all the combinations. Of course this can be quite a lot of work and not very elegant if you have a lot of combinations. If you have three distinct values for every attribute, you already have 27 different cases to handle.

Multiple symbolization would also be cool for multiple symbolizations of the same layer for different map scales (without having to load the layer multiple times). Autodesk Map3D handles this nicely. It would be surely nice to have these features... The new generation symbology I'm developing doesn't include neither of them, but I'm trying to keep it extensible so such addition in future would be possible. I think this is one of the features where creating usable GUI is actually harder than the implementation itself :) Martin ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user
Re: [Qgis-user] Multiple Symbolization Rules per Layer
Certainly at some point. But I think that the trac is actually not easily followed by users. Actually, what I'm doing now is the other way around: I'm incorporating to a newer page all the tickets labeled as improvements + those currently listed in my page and including the link to the ticket. The idea behind all this is that ideas for enhancements must be discussed and agreed upon by users before they become tickets. Hopefully users should also establish priorities.

Why not adding these to the wishlist in the QGIS trac? This way, devs sooner or later will certainly read them.

Hi Andreas, currently it's possible to use only one attribute for the symbolization, so combination of the two attributes should do the job. Another option would be to write a special renderer class, however this has its own glitches.
