Class GridMetrics.Spacing

java.lang.Object
heronarts.lx.studio.ui.timeline.GridMetrics.Spacing
Enclosing class:
GridMetrics
public static class GridMetrics.Spacing extends Object
The spacing values are read by the UI thread to draw grid backgrounds and labels, but they are written by the main LX thread when GridMetrics responds to relevant parameter changes. We use a non-locked but pseudo-immutable class here to hold the values such that at any given point in time the UI thread will get an internally consistent set of all the values (and in the case the values are out of date, there will be a pending redraw() call that results in the latest values being retrieved in a future pass).
