| Hi,
I believe that Jody has updated the tutorial so it only works for uDig 1.1.x. You can download the latest SDK at:
Don't worry, the standard functionality is pretty stable. The unstable functionality shows itself in the edit tools and saving layers.
It is best to work against these branches since I can quickly make modifications when you encounter issues.

A few issues with the distance tool tutorial (with SDK installed per the Quickstart): - The DistanceTool class is supposed to extend net.refractions.udig.project.ui.tool.SimpleTool, which doesn't seem to exist. There is an AbstractTool, but no SimpleTool. AbstractTool has the methods mousePressed(MapMouseEvent) and mouseReleased(MapMouseEvent), rather than onMousePressed(MapMouseEvent) and onMouseReleased(MapMouseEvent), suggested as overrides in the tutorial.
- The import org.geotools.geometry.jts.JTS doesn't seem to exist, either, so I can't call the orthodromicDistance method. Only org.geotools.geometry.JTS
- The calls to getContext().getActionBars().getStatusLineManager() don't work, since IToolContext doesn't have a method called getActionBars. This should be getContext.getStatusBar(), I think.
- If I use AbstractTool as a super for DistanceTool (tried with constructor calls to super(MOUSE), super(MOTION), etc.) and override the mousePressed and mouseReleased methods, they are never called.
Also, as an aside, the tool doesn't show up on the toolbar until I first select it from the Tools->Info Tools menu, even though onToolbar is set to true in plugin.xml. Sorry if these have previously been addressed. I tried to find a search option in the list archives, but didn't see one. Jeff Hi Jeff,
The easiest thing is to create a new plugin with your customized zoom
tools. The distance tool tutorial explains how to create a tool and
plugin. The NavCommandFactory is a good place to look for commands
that can be used to modify the ViewportModel. Nav commands are used
to change the zoom and bounds of the map. You can get at an instance
of the class from a tool implementation with the line:
getContext().getNavCommandFactory().
