Re: [udig-devel] ModalTool Change Listener

[Jody Garnett <jody.garnett@xxxxxxxxx>]

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 :).

Thanks for explaining - that helps a lot.

A couple of ideas (feel free to ignore):

- I wonder if we can use the existing coordinate area at the bottom of the screen. Like when you select a coordinate we can use that for editing. It would be similar to how it is used now where it provides dynamic feedback as you move the co-ordinate with the mouse?

- The tool option area is available; you could make use of it for this purpose (it has the advantage of smoothly being available only when editing).
