[udig-devel] ToolManager and finding tools

[Emily Gouge <egouge@xxxxxxxxxxxxxxx>]

Hi uDiggers,

I'm using uDig as the mapping component of a larger project to track and 
manage Patrol data.  The quick summary is - Rangers (or others) take GPS 
devices into the field (park or protected area) and record information 
(wildlife sightings, poaching sighting) using these devices.  The 
application then provides the ability to download, manage, and report on 
the information collected.

So far I've had little trouble integrating uDig - so thanks to everyone.

I have one question - I'm developing a very simple map view that is not 
meant to be used for anything other than quickly viewing data.  I want 
it to only have a few simple tools (pan, zoom and possibly one or two 
custom tools).  As a result I'm creating my own custom toolbar with the 
set of tools I need.

I want to use the ToolManager to find the defined tools and add them to 
my custom toolbar.  I tried using the ToolManager.findTool(toolID) 
function but it doesn't search non-modal tools and it doesn't return the 
tool proxy (that contains the name, image and other information I need).

The solution I came up with was to add a function to the ToolManager 
called findToolProxy(toolId)  [as shown below].  This function searchs 
all tools (modal, action and background) and returns the associated 
toolproxy.   This function would also need to be added to the IToolManager.

If there is some better way of accessing the Tool extensions please 
point me at it and I'll have a look.  Otherwise, (if I create a patch 
and submit it via git) would it be possible to get this update into udig?

Thanks,
Emily
