Listening for window events
Adobe AIR 1.0 and later
To listen for the events dispatched by a window, register a listener with the window instance. For example, to listen for
the closing event, register a listener with the window as follows:
myWindow.addEventListener(Event.CLOSING, onClosingEvent);
When an event is dispatched, the target property references the window sending the event.
Most window events have two related messages. The first message signals that a window change is imminent (and can
be canceled), while the second message signals that the change has occurred. For example, when a user clicks the close
button of a window, the closing event message is dispatched. If no listeners cancel the event, the window closes and
the close event is dispatched to any listeners.
Typically, the warning events, such as closing, are only dispatched when system chrome has been used to trigger an
event. Calling the window close() method, for example, does not automatically dispatch the closing event—only
the close event is dispatched. You can, however, construct a closing event object and dispatch it using the window
dispatchEvent() method.
The window events that dispatch an Event object are:
Event Description
activate Dispatched when the window receives focus.
deactivate Dispatched when the window loses focus
closing Dispatched when the window is about to close. This only occurs automatically when the system chrome close
button is pressed or, on Mac OS X, when the Quit command is invoked.
close Dispatched when the window has closed.
