[Qgis-developer] QGIS 2.0 layertree: decoupling logical grouping and the drawing order

[Andreas Neumann]

 Hi,

 Next to being a QGIS user, we are also Autodesk users. One feature I 
 like in Autodesk which doesn't exist in QGIS is the decoupling of the 
 logical grouping (our existing nested hierarchies) from the actual 
 drawing order.

 In Autodesk you have two tabs in the layer tree. One tab is for the 
 logical grouping, in the other tab you get a flat list of the drawing 
 order.

 Use case: you want to logically group layers from different media (say 
 all gaz layers, all water layers, all waste-water layers), but in the 
 drawing order you first want to draw the polygon features, then the line 
 features, then the point features.

 Something to discuss in the Zurich meeting?

 Attached is also the relevant part of the GUI in Autodesk. It is 
 german. The "Gruppen" tab means "Groups", the "Zeichnungsreihenfolge" 
 tab means "drawing order".

 Do you also think that this decoupling would be useful for upcoming 
 QGIS versions?

 Andreas
