Base Map Fader for Flex 2.2?

NathanEnge — Sat, 11 Dec 2021 12:26:08 GMT

I'm trying to port over the Base Map Fader from SFV1.3 into the 202. I'm getting a bunch of errors, when I try to implement it in my current index.mxml for Flex 2.2. Has anybody done this yet?

Nathan,

Several changes are required:

    lyr.visible = true; 
    lyr2.visible = true; 
    lyr.alpha = fader.value;

Thanks for this Robert. And if I wanted to integrate it with the BaseMapSwitcher so that the slider is always directly beneath the button bar, intead of at the fixed location where it is right now?
