class Opal::UI::CharacterGrid

Overview

Interactive, highly configurable 2D character grid control. Renders regular horizontal and vertical grid lines with customizable intervals, glyph styles (solid, heavy, double, dashed, dotted, crosses, etc.), major/minor lines, panning offsets, interval scaling (zoom), mouse dragging, and coordinate rulers.
