I'm at the moment writing several NCL for different types of non awt Components. Even though most of them work I am never quite sure what the location of the JSNCLData is supposed to do. In the example (JTree) in the JavaStar tutorial it symbolises the upper left corner of the tree row that was clicked on. what is this good for? how does javastar know how big the row is, if I just has the location of the upper left corner? Or can the location just be any point within the surrounding component (in the example the JTree)? Why does JavaStar need this location anyway since it already gets the exact coordinates of a the multiclick? I found out that most of my NCL work (some don't)even if I pass random values for the JSNCLData location. Can anyone explain this?
