Hi Maaza, 2011/9/28 maaza mekuria sail...@yahoo.com: Since I never heard from anyone. But I tried a few things and I resorted to using an ESRI Shape File provider (instead of ogr) in the QgsVectorFileWriter instead of the QgsVectorLayer. The parameters are ill-defined and not properly

[Qgis-developer] Module piping GUI [Was: analytical workflow]

2011-09-29 Thread Camilo Polymeris
Hello everyone, in an earlier thread, the implementation of analytical workflows --sets of modules with linked inputs and outputs-- was discussed. While this can currently be attained using Python scripts, a GUI to interactively construct these workflows would be a nice addition to the

But AFAIK this has to be implemented in Python, not in Qt. Is there an equivalent framework for Python? Paolo, You can access all the Qt stuff in Python via PyQt. I'm pretty sure this is what Martin is talking about:

HI If you are thinking about designing a GUI for a graphical workbench, I would definitely have a look at the way FME is handling it. I think it requires a combination of both approaches: Normally it is a graph-style (connect-the-boxes) GUI but often it requires in addition: multiple

yes - you are right. FME is a ETL tool (like GeoKettle, Java based). I still think it can be a source of inspiration. ETL may be something different but it has a LOT in common with what you probably want to achieve in a model builder for analytical workflows. I agree that we can start from
