lookAndFeelChanged() Slider?

I can't seem to change the colour of my slider text box text. I'm using my own lookandfeel class, which is basically a copy of LookAndFeel_v2. I tried overriding createSliderTextBox() but it never gets called, but LookAndFeel_v2::createSliderTextBox() does get called. At this point I would usually try a call to lookAndFeelChanged(), but for a slider it's protected? Any ideas? I'm probably missing something stupid here..

Arghh. I forgot to add 'override' to my method prototype. Now that it's hitting createSliderTextBox() I can probably work out the rest.
