Avalonia Routed Events

Overview

Avalonia uses routed events that travel the logical tree. Three strategies:

• Bubble — source → root (default for most input events)
• Tunnel — root → source (Preview prefix by convention)
• Direct — only raised on source element

All input events (PointerPressed, KeyDown, etc.) are routed.

Handling Events

XAML:

<Button Click="Button_Click"/>
<StackPanel PointerPressed="Panel_PointerPressed"/>
