Almost all the code you write is executed, directly or indirectly, in response to events. An event is a special kind of property that represents a runtime occurrence, often a user action. The code that responds directly to an event—called an event handler—is a Delphi procedure. The sections that follow show how to:

• Generate a new event handler.
• Generate a handler for a component's default event.
• Locate event handlers.
• Associate an event with an existing event handler.
• Associate menu events with event handlers.
• Delete event handlers.
