Class BranchSlider

java.lang.Object

ur_rna.StructureEditor.services.drawing.DrawHandle

ur_rna.StructureEditor.services.drawing.BranchSlider

public class BranchSlider
extends DrawHandle

A DrawHandle that allows a user to "slide" an RNA branch (i.e. a helix and everything on one side of it.) along the smooth arc of the circular loop at the helix's base.
