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

[Andreas Neumann]

 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 input/output, control flows, where elements from the 
 patch-style GUI would come in - eg when patching an attribute from one 
 source or transformer to a different attribute in a destination dataset 
 or transformer.

 I believe in FME (Safe software) - which is the most well-known GUI 
 modeler in GIS, it is a combination of both approaches with additional 
 flow controls transformers (e.g. tester with branches).

 I work a lot with FME - it would be very cool to have something similar 
 for QGIS workflows.

 FME workbench is also programmed with qt, by the way.

 Here is a sample screenshot from FME:
