 i want to listen editing tools like  , Polygon , LineTool ….. . User can draw shapes free by mouse , but we need to enter coordinates by hand  relative to first point .  for example while editing via  polygon tool  
 relative to previous point :  first point  11 (x0), 12 (y0) ( exact point location )    second point :   x0 + 100 , y0 + 50  entering coord relative by angle :  first point  11 (x0), 12 (y0) ( exact point location )    second point :  sin 30 *  x0 + cos 30 * y0  
 I'm developing a view to enter these coords ,  if user enters coords and types enter, entered coords will be added currently editing shape.  that s why i want to known when  a edit tool enabled  , so that i can enable or disable text boxes to enter coordinates and can show view if necessary .   i ll need a few more views for my application depends on existing and custom tools . 
 i ve found a workaround , when a  modal tool activates  , it runs  a command so map change event fires :).

                    Can I ask why you want to do this? It will help me figure out how we should fix it … normally the tools are "driving" the application (you know registering listeners, changing the cursor, proving a context menu, taking over the selection the map advertises, etc…) 
 if we are forced to listen to the tools enable and disable then perhaps you have discovered a new responsibility for the tools? 
 So yes please tell me more :-) 
 If ToolLifecycleListener is expected to be called then we should be able to make a fix; perhaps you could check in ToolManager with a debugger and spot where we should fire the event from? On Monday, 16 April 2012 at 11:41 PM, omur yavuz wrote: 
                    I've read my previous mail again and its slipshod, apoligies. 
 I want to catch whenever active modal tool changes , smth like 
 ApplicationGIS.getToolManager().addChangeListener(IToolChangeListener); IToolChangeListener { activeToolChanged(Event evt) ; } 
 Looks like there is no implementation like this. so i tried to listen specific tools lifecycle ; 
 ApplicationGIS.getToolManager().findTool("......polygonEdit").addListener(new ToolLifecycleListener(){ 
 					public void changed(ToolLifecycleEvent event) { 						// TODO Auto-generated method stub 						bla bla bla 					} }) 
 but changed method is not being called when edit tool activated or deactivated. 
 can you give me an advice plz :)

 I ve got a problem with modal tools :). i want to listen modal tool selection change and activate my viewport based selection of the tool.  For example   i ll make myviewpart only polygon tool and line tool selected .  i tried several methods to do ; 
 1)  Listening Balackboard : its working to listen edit state  , i can catch starting editing  but can't  handle  switching to another tool like zoom  2)  listening tool lifecycle :  added IToolLifecycleListener  ,  workbench didn't call change event after i clicked tool. 
 can you give me an advice ?
