[udig-devel] create a command

[Andrea Antonello]

Alright, I need some explanation on tools creation, else I will end up
to fill the whole UI of Udig with randomly ordered JGrass commands.

Example:
I want to create a set of tools able to import and export different map
formats into and out of the JGrass workspace.
So what I do is:

1) Create a category: so I
- supply an id
- have no idea on what to say for commandId, since there will be a bunch
of command in this category
- give the icon path
- give a nice name
- have no idea about what the selectionProvider does
- have no idea about what the applicabilityId is

2) Create an actionTool: so I
- set the ID and the tooltip and the name and the class and the icon
- choose whether to put it on the toolbar (where?) or not
- supply the id of the just created category
- don't know how to handle commandIDs, commandHandler and menuPath even
if they sound like very good to tune configuration.


Con someone please light my way?

Thanks,
Andrea
