Hi Victor, The callback functions for the buttons are defined and registered in the file kln89.cxx in src/Instrumentation/kln89 - there is no nasal glue for the kln89. I'm not sure why your buttons are not working, but if you want to send me your code off-list I'll take a look. However, I'm not sure that it's currently possible to use the display in a 3D instrument without source code modifications. It currently draws raw opengl in 2D directly to the screen. Having said that, I *think* it uses the same mechanism as the panel hot spots, and I seem to recall that they work on the 3D panels? On my todo list is to render the display to texture like the weather radar is, so it can be properly used in a 3D instrument. I'd be interested to know how you are getting on - do you see the display properly on your 3D instrument, but just without the buttons working?
