[udig-devel] Capture events when user clicks the map?

[Jody Garnett]

Have a look at the normal DistanceTool tutorial; it provides a tool that 
responds to mouse down, and mouse release events. You can modify the 
example to take care of double clicks. When you do get a double click 
you can do a query on your hospital layer to see if they clicked on one. 
You may also enjoy looking at the InfoTool (it operates as a single 
click; and opens a view up to show the result of a query at that location).

This email list is a great location for these kinds of questions.
