rotating dial.... usng .xml????

[Guest sphing]

Hello,I'm working on a fuel totalizer for a dc-9-41 and there is an outer dial, manually rotated by pilot, that shows aircraft/cargo/fuel weight. This dial in no way is conencted to any FS variables.How do I make code for a dial that only rotates by "+" or "-" mouse-click events?Thanks,John
