Applying a Synth Look and Feel to Sliders?

Question

Hey Guys,

I have a bunch of sliders that I am trying to apply a custom thumb to. The dimensions of it are 12x20, and I am applying it using a synth look and feel with the code below. This displays the thumb correctly for horizontal sliders, but once I make a vertical one the thumb gets distorted on the edges. Is there any better way to do this? Also, The thumb pressed code doesn't do anything, I would assume the reason for that is that sliderThumbs don't have a "pressed state"? Is there a way to make the L&F change on a slider when it is pressed? Thanks beforehand!!!

Cheers, Lukas
