com.flexganttfx.view.graphics.renderer.RendererBase

com.flexganttfx.view.graphics.layer.SystemLayer<R>

Type Parameters:

R - the type of the rows

public abstract class SystemLayer<R extends Row<?,?,?>>
extends RendererBase

System layers are used in the background and foreground of each row. A background layer gets drawn before the activities are drawn while a foreground layer gets drawn after the activities are drawn. Each layer is specialized on drawing one type of information: current time, selected time intervals, grid lines, and so on. The graphics view manages the layers in two lists and provides convenience methods to easily look them up.
