Syntax

public class ArrowPrimitive : BasePrimitive, IDisposable, INotifyPropertyChanged, ICustomTypeDescriptor, ISupportSystemSkin, IStylableNode, IPrimitive
Remarks

ArrowPrimitive provides rendering capabilities for arrows pointing in various directions (up, down, left, right). It's commonly used in dropdown buttons, scroll bars, menus, and other UI elements that require directional indicators.

The primitive extends BasePrimitive and supports various arrow styles, sizes, and colors. It automatically handles arrow direction and scales appropriately based on the available space.

The class defines minimum sizes for horizontal and vertical arrows to ensure proper visual representation even in constrained layouts.
