Hi Eric, > I have a simple function (x,y)->z that I display with a DisplayImplJ2D and > I would like to > show the z value when the user press the right mouse button. > How can I do that ? You need to construct a DisplayListener and add it to your DisplayImplJ2D. In its displayChanged(DisplayEvent e) method, if e.getId() == DisplayEvent.MOUSE_PRESSED_RIGHT, then apply the code in the second part of the answer at: http://www.unidata.ucar.edu/staff/russ/visad/msg00862.html Note also that the visad/rabin/Rain.java program accomplishes this in a different way, by constructing a RealTuple object and using it as a custom cursor via a DirectManipulationRenderer. It even uses a ScalarMap to Display.Shape to make a cross-hair cursor. Cheers, Bill ---------------------------------------------------------- Bill Hibbard, SSEC, 1225 W.
