I was charged with a felony 6 years ago and the charges were all dismissed, does that mean I was convicted?

Okay, I'm confused because I'm applying for jobs now and on the application it asks if I have ever been convicted of a felony. When I went to court for this charge the judge told me that it would never show on my record because it was dismissed. Last year I had a hard time getting a fingerprint clearance card b/c of the charges but as soon as I showed them the paperwork that it was dismissed they cleared me no questions asked. On this job I'm applying for asks if I have ever been convicted & the disposition. On my paperwork it says disposition "dismissed". I am not sure because it was a deferred judgement so would that mean I was convicted? It was a long time ago when I was young and stupid and I'm embarrased by it. I don't want to put it on my application but if I have to I will.
