Has anyone added ticks into the Spark Slider? I am having a hard time understanding how to create the skin because the tickValues are not static. So far the skinning I have done can all be done in MXML but it seems like the ticks would need to be drawn in ActionScript since you'd need to look at the tickValues array (if you implement like the mx:Slider did).
Funny you mention this - I wondered the same thing while looking at your previous question. Attached is a sample track skin that demonstrates a very naive approach to adding tick marks (see HSliderTrackSkinTicks.mxml).
Note: This code is specific to the project we were working on in http://forums.adobe.com/message/2476351#2476351
Interesting... I was trying to add the ticks as a separate SkinPart to the Slider itself and simply could not get them to draw. I never considered adding them to the track. Wonderful! Thanks so much!
