DVScrollBar

Description

A generic vertical scrollbar, used in DScrollPanel. See the horizontal alternative here.

The scrollbar notably contains DVScrollBar.btnUp, DVScrollBar.btnDown, and DVScrollBar.btnGrip which are the up button, down button, and grip respectively. Editing the paint functions of these allows custom scrollbar styling (See DScrollPanel:GetVBar for an example), although it is a better idea to use Derma Skins.
