Hi Michael Bishop,
I have been beavering on my project and have successfully converted my
screen coordinates to documents and can interact with my database to
retrieve the information for the current view and show red spots on the
areas where accidents have happend on the map ...now I need to make the
red spots active so when a user clicks on a red spot the relevant
information about that particular accident is displayed ...i simply used
the following code to create the red spot:
Graphics spot = canvas.getGraphics();
spot.setColor(Color.RED);
spot.fillOval(x,y,22,22);
spot.dispose();
but i cant assign an ActionEvent to the spot ...Any ideas?
Many thanks in advance :)
