Draw Commands "live" until their isValid method returns false. So
when you want to turn off/kill the command call setValid(false). Or
override the isValid method to know when it is no longer needed.

Hi again everybody,
The plugin development is going well (much of it thanks to your help),
but now I'm running into another lack-of-knowledge problem:
I want to display a toggleable grid over the current map that
illustrates the available tile boundaries as a navigation guide. I've
been able to get a Ctrl-Click to display the lines through calls to
getContext().sendASyncCommand((getContext().getDrawFactory
().createDrawShapeCommand(...)),
like on the net.refractions.udig.tutorials.tool.coordinate tutorial.
However, these lines seem to live forever on the map, and I don't see
any obvious way of clearing them and/or temporarily disabling them.
Any suggestions? I could conceivably generate a grid layer on the WMS
proxy, but it would make more sense in some ways to do it through the
plugin.
Jeff
