[Qgis-user] Is there an algorithm in Processing graphical modeler to select features in a geometryless table?
Hi, I'm tring to build a graphical modeler within the menu Processing. In my process, I need at a moment to select features from a csv table. But none of the select... algorithms (select by attribute, select by expression...) I can find in the algorithms list does accept table as input. Is there a solution? Or is it a bug so that I report it? Thanks ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user
Re: [Qgis-user] Web-Client: same host QGIS-Server-WMS not shown
Hello Bernhard, Unfortunately replacing the server name with 127.0.0.1 does not do the trick for me. I'm going nuts, because I have no clue how to handle it. I've tried an external wms coming from a qgis server. That works. Only my own qgis-server-wms isnt shown in the map or the layertree at all. Anything else i can do?

If it is the same machine try replacing the server name with 127.0.0.1 in the URL (in the project file), this works for me.

[Qgis-user] Mobile Client - symbol color changes
Dear list, when I use the mobile client with colored svg-symbols and arial images at the same time, the color of the symbols changes when moving or zooming the map. In my config.js under Config.map.wmsParams - 'FORMAT' stands the value 'image/png; mode=8bit'. For lines or polygons this effect doesn't occur. Can someone give me a hint how to solve this problem?

Dear all, OS: Debian testing QGIS: 2.9.0-Master (1:2.9.0+git20150517+173ee45+99unstable) I receive nightly updates which restarted again on 6th May, after a break when the previous update was 5th April 2015 QGIS was functioning properly with the 5th April update. I used QGIS for the first time since 6th May and when I tried to save an imported .csv file as a shape file, using save as.., QGIS crashed and closed as soon as I selected this option. A similar fault was reported back in 2007 and one option was to check the attributes of the layer. I checked and all appears to be in order. To check if the original file was corrupted, I repeated the action of saving as a shape file with an existing shapefile (that has been used with QGIS in the past) - same result of QGIS crashing. I have the same OS QGIS build on my notebook and the same problem is present. Is anyone else experiencing the same problem with the latest nightly-builds? I would be very grateful for any advice provided to help fix this problem very many thanks in advance yours Neil -- View this message in context: http://osgeo-org.1560.x6.nabble.com/QGIS-2-9-0-Master-crashes-when-selecting-save-as-tp5206209.html Sent from the Quantum GIS - User mailing list archive at Nabble.com. ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user

Re: [Qgis-user] Maps generation with Python (or Atlas ?)
Hi, 2015-05-18 17:51 GMT+02:00 Benoît Laurent blaur...@heurisis.eu: Hello, I would like to generate a series of maps representing tracks with stops along them. For each track, I have got a group of two layers, one for the linear, one for the points that have associated information (basically name and time of the stops). First, is there a better way to achieve this ? For the moment, I have to handle two types of layer. It is the beginning of my problems. As the tracks overlap, I would like to generate a map for each track where only the current selected track appears. The others would be hidden. I had a try with Atlas generation. It perfectly works except that I can't hide the other tracks. You can style your coverage layer so that only atlas current feature will appear. In categorized style, use an expression like $id=$atlasfeatureid. You'll get 0 (false) and 1 (true) when classing. Set the 0 features style so that they become invisible or transparent. I also had a try with a Python script. I managed to iterate over the groups of layers but I can't refresh the map canvas during the Python script. So, it doesn't work. A snippet of your code may help but I remember I had to face such a problem and it was because after *myatlas.beginRender()*, I forgot to set active the export of the atlas, sthg like *mycomposition.setAtlasMode(QgsComposition.ExportAtlas)* Do others faced a similar problem ?
