Hello Martin
I'm inching closer! I looked carefully at my code again last night,
particularly at the passing of the presenter class to the Thumb Skin. I saw
that your example code in the customSlider_creationCompleteHandler you assigned
a new instance of SliderView_Presenter to variable 'p' and then passed this to
the 'presenter' property of the customSlider. What I needed was to assign
'this' to 'p' in my SliderView_Presenter and pass it to the customSlider. That
done, as my buttonColour property changes in SliderView_Presenter the Skin Rect
fill colour, bound to the buttonColour property, now changes. Yippee!
However (and it was going so well!) the following function prevents the HSlider
button from moving:
override protected function partAdded(partName:String,
instance:Object):void {
if (partName == "thumb") {
_thumbInst = instance;
}
Can you suggest why the Thumb button is no longer draggable?
Thank you.
Chris
