Subject: Re: Activity Indicator in accordion header

Another thought might be to ditch the renderer approach entirely and to
create a custom subclass of Accordion along with a custom skin extending
org.apache.pivot.wtk.skin.terra.TerraAccordionSkin.
(Or just copy both classes and edit to create your own parallel versions
rather than extending)
I haven't prototyped it, but I think it (or something similar) should work,
although I'm not sure it is necessarily preferable to just managing the
repaint callbacks yourself.

TerraAccordionSkin contains these 2 inner classes which deal with the
Accordion headers and will normally use a supplied renderer to render the
header.
org.apache.pivot.wtk.skin.terra.TerraAccordionSkin.PanelHeader
org.apache.pivot.wtk.skin.terra.TerraAccordionSkin.PanelHeaderSkin

Your TerraAccordionSkin might override these so that the header is a simply
a real BoxPane with an ActivityIndicator and a Label inside.  Then the
BoxPane skin (and ActivityIndicator & Label skins) will take care of
painting, and more importantly, animating.
(ie, use real, fully fledged Components, rather than a Renderer for each
header)

For more flexibility you might expose the BoxPane used for each header so
that you can set its content, properties and styles as required.
