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 :).
