Hi to all,
Can any one please help me. When I click any place on the JMapFrame I want to
get a point on the JMapFrame i.e I want to create a new point in JMapFrame. I
wrote some code for this after that I don't know what I have do. Because I am
not a that much programmer. Please find here attached file which contains my
code.
Thanks in advance.
Regards,
D Pardhu.
