[Qgis-developer] WFS-alike plugin with caching: approach? (Was WFS still fetches everything)
Hi, I'd like to enhance a WFS-alike Python plugin with caching. Currently it simply creates a vector layer and attaches a REST webservice on it which returns GeoJSON. From this time, the layer is not controlled anymore by the plugin and reloads everytime the layer get's zoomed/panned or after QGIS project is re-opened. Now I'd like to refactor it and get more control over the layer and implement caching. 1. What would be the best approach to implement the caching ? With a temp file? 2. How to tell QGIS after reloading the project, that the plugin is needed (on a different machine or in case the plugin got de-installed)?

IMHO having a public bugtracker is the best way to have early testing. Trying a plugin, discovering a bug, and not finding a public method to open it is very frustrating, in my experience.

[Qgis-developer] qlr files and preservation of layerids
Hi, I have a scenario where I would like to use qlr files, but need the old layer ids preserved when I import them into the project. I see that in its current incarnation the layerid is not exported and hence also can't be imported. The reasoning is that other projects link to layers into my projects (embedded layers and groups) and thus layer id preservation is important. In my projects I would need to replace some layers with qlr layers that have similar settings, but differ a bit. Thus the layer ids need to be preserved. Could there be an option when exporting and/or importing the qlr files that would allow the preservation of the layer ids? Thanks, Andreas ___ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer
[Qgis-developer] QGIS Server Python plugins docs
Hello Jef, Do you know if the new Python Plugin API for QGIS Server is available online under qgis.org ? I'd rather prefer linking to official online docs instead of my hosted copy: http://www.itopen.it/qgis/serverplugins/api/ Can you maybe add it to the build? It was generated parsing the sip files under /python/server -- Alessandro Pasotti w3: www.itopen.it ___ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer
[Qgis-developer] Raster Ramp color
Hello. I am trying to change the simbology of a DEM raster using a default pseudocolor ramp from the max and min height. How can I select the ramp and define the settings of the classification in python? thank you -- View this message in context: http://osgeo-org.1560.x6.nabble.com/Raster-Ramp-color-tp5201055.html Sent from the Quantum GIS - Developer mailing list archive at Nabble.com. ___ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer
