flash.events.InvokeEvent - Adobe® Flex® 4 Language Reference (Flex 4)

Package	flash.events
Class	public class InvokeEvent
Inheritance	InvokeEvent Event Object

Language Version:

ActionScript 3.0

Runtime Versions:

AIR 1.0

The NativeApplication object of an AIR application dispatches an invoke event when the application is invoked.

The NativeApplication object always dispatches an invoke event when an application is launched, but the event may be dispatched at other times as well. For example, a running application dispatches an additional InvokeEvent when a user activates a file associated with the application.

Only a single instance of a particular application can be launched. Subsequent attempts to launch the application will result in a new invoke event dispatched by the NativeApplication object of the running instance. It is an application's responsibility to handle this event and take the appropriate action, such as opening a new application window to display the data in a file.

InvokeEvent objects are dispatched by the NativeApplication object (NativeApplication.nativeApplication). To receive invoke events, call the addEventListener() method of the NativeApplication object. When an event listener registers for an invoke event, it will also receive all invoke events that occurred before the registration. These earlier events are dispatched after the call to addEventListener() returns, but not necessarily before a new invoke event that might be might be dispatched after registration. Thus, you should not rely on dispatch order.

Property Detail

arguments

property

arguments:Array [read-only]

Runtime Versions:

AIR 1.0

The array of string arguments passed during this invocation. If this is a command line invocation, the array contains the command line arguments (excluding the process name).

Note: When multiple files are selected and opened on Mac^® OS X, AIR dispatches a single invoke event containing the names of all the selected files in the arguments array. On Windows^® and Linux, however, AIR dispatches a separate invoke event for each selected file containing only that filename in the arguments array.

Implementation
public function get arguments():Array

currentDirectory

property

currentDirectory:File [read-only]

Runtime Versions:

AIR 1.0

The directory that should be used to resolve any relative paths in the arguments array.

If an application is started from the command line, this property is typically set to the current working directory of the command line shell from which the application was started. If an application is launched from the GUI shell, this is typically the file system root.

Implementation
public function get currentDirectory():File

reason

property

reason:String [read-only]

Runtime Versions:

AIR 1.5.1

The reason for this InvokeEvent. This property indicates whether the application was launched manually by the user or automatically at login. Possible values are enumerated as constants in the InvokeEventReason class:

InvokeEventReason constant	Meaning
`LOGIN`	Launched automatically at at login.
`STANDARD`	Launched for any other reason.

Implementation
public function get reason():String

INVOKE

Constant

public static const INVOKE:String = "invoke"

Language Version:

The InvokeEvent.INVOKE constant defines the value of the type property of an InvokeEvent object.

The InvokeEvent object has the following properties:

Properties	Values
`arguments`	The array of string arguments passed during this invocation.
`currentDirectory`	a File object representing the directory that should be used to resolve any relative paths in the arguments array.
`reason`	a code indicating whether the invoke event was dispatched because the application started automatically at login (`InvokeEventReason.LOGIN`), or for another reason (`InvokeEventReason.STANDARD`). Available as of AIR version 1.5.1.
`bubbles`	`false`.
`cancelable`	`false`; there is no default behavior to cancel.
`currentTarget`	Indicates the object that is actively processing this InvokeEvent object with an event listener.
`target`	Always the NativeApplication object.
