Just some more clarifications regarding populating the LegendItem list: 1. Should the LegendItem list be always (even without Legend View opened) in sync with the Layers list? Or is this just for LegendView usage?
2. If it will always be in sync, where should we intercept sync-ing the two lists? I tried poking into AddLayer(s)Command and it seems to be a good starting point, but are there other areas in the system where it adds layers but not thru these commands? Thanks!

When you have that working we will "switch over" to using it. The layer view will remain a useful (as it shows all layers; and shows draw order; and allows direct manipulation of draw order). I can imagine people having both open for a few tasks... -- Jody Garnett On Tuesday, 14 February 2012 at 3:24 PM, Nazareno Chan wrote: For now, which direction are we taking?

I am also concerned about loading previously saved uDig project files. 1. Most code has already migrated to the IMap.getLayerList() method 2. It should be easy enough to do a traverse of the LegendItem tree and produce an answer for getLayerList() however ... 3. Jesse is correct that there may be some event listeners that are watching for context model to change its list of layers 4. I think we need to keep ContextModel around for one more release; and switch the rendering code over to listen to getLegendItems() changing. This also gives us a chance to load previously created projects; and notice if the ContextModel is non empty (and use it to define the initial list of legend items) -- Jody Garnett On Wednesday, 8 February 2012 at 6:17 PM, Jesse Eichar wrote: Good luck.

This would result in quite a few changes across the Project Model but at this stage all I have done (locally at this stage) is add a list of LegendItems to the Map. This legend (list of items) will replace the ContextModel which stores a list of layers for the map. Give us a yell if you can think of any issues that might arise from removing ContextModel. _______________________________________________ User-friendly Desktop Internet GIS (uDig) http://udig.refractions.net http://lists.refractions.net/mailman/listinfo/udig-devel _______________________________________________ User-friendly Desktop Internet GIS (uDig) http://udig.refractions.net http://lists.refractions.net/mailman/listinfo/udig-devel ________________________________ The contents of this email are confidential and may be subject to legal or professional privilege and copyright.
