Hi all,
Some people already discovered it ;-):
http://darrencope.com/2011/12/01/new-control-rendering-order-option-in-qgis/
Thanks to the work of Jürgen there is now a decoupling of the layer
structuring and the rendering order available in current master. It
allows you to group layers thematically but decouple it from the
rendering order. There is a separate panel called "Layer Order"
available with a flat list of all layers where you can drag layers
around to change the rendering order. There is a checkbox at the bottom
of the two panels "Layers" and "Layer Order" to control which one takes
precedence.
The typical use case is that one generally wants polygon layers at the
bottom, then line layers and point layers and labeling, but one does not
want to wildly mix different topics. With the decoupling now you can
group layers by topics in the regular layer panel and control the
rendering order separately in the "Layer Order" panel.
Be careful with using this new feature with QGIS Webclient - currently
it will screw up if you use this mechanism. QGIS Webclient needs to be
made aware that the rendering order is now different from the order in
the layer tree. But with some modifications, QGIS Webclient will benefit
from this enhancement as well.
Please test this new functionality and report bugs,
Andreas
