Class LayeredPanel

Namespace
PluginUI
Assembly
PluginUI.dll

Stack of full-size layers drawn on top of each other (VSTGUI CLayeredViewContainer): backgrounds, a control layer, an overlay page that fades in, a modulation layer… Every child fills the panel (minus its Margin, with its alignment), the last child is on top, and layer opacity is composited properly (a half-transparent layer does not reveal the overlaps of its own children).
