Hi Laurent, Alan I have just committed the changes exposing plTranslateCursor in the C++ binding. I have also documented it in the main API section - Alan, please tell me if this is not appropriate as it will not be exposed in other bindings. Also I am not 100% sure about the plGraphicsIn::state variable. This doesn't appear to be documented anywhere, there are just references to X11/X.h. I found a copy of that online, but haven't had chance to read up in detail. We really should document it ourselves.
Laurent, if you are making use of the wxPLplotwindow templated class, then the easiest way to catch the mouse position now using the latest source is to inherit from this class and overload the virtual function OnLocate, which accepts a const reference to a PLGraphicsIn. This structure will have already been passed to plTranslateCursor and will have all relevant variables filled in. You can check wxPLplotDemo for an example of how this works. Alternatively you can check out wxPLplotwindow.h (in particular the OnMouse method) to see how you can write your own event capture code if you prefer.
