Usage 1:
on(mouseDownOutside){
...
}
Usage 2:
listenerObject= new Object();listenerObject.mouseDownOutside = function(eventObject){...}windowInstance.addEventListener("mouseDownOutside",listenerObject)
Event; broadcast to all registered listeners when the mouse is clicked (released) outside the modal window. This event is rarely used, but you can use it to dismiss a window if the user tries to interact with something outside of it.
The first usage example uses an on() handler and must be attached directly to a Window component instance. The keyword this, used inside an on() handler attached to a component, refers to the component instance. For example, the following code, attached to the Window component instance myWindowComponent, sends "_level0.myWindowComponent" to the Output panel:
on(click){
trace(this);
}
The second usage example uses a dispatcher/listener event model. A component instance (windowInstance) dispatches an event (in this case, mouseDownOutside) and the event is handled by a function attached to a listener object (listenerObject) that you create. You define a method with the same name as the event on the listener object; the method is called when the event is triggered. When the event is triggered, it automatically passes an event object (eventObject) to the listener object method. The event object has a set of properties that contains information about the event. You can use these properties to write code that handles the event. Finally, you call the UIEventDispatcher.addEventListener() method on the component instance that broadcasts the event to register the listener with the instance. When the instance dispatches the event, the listener is called.
For more information about event objects, see Event Objects.
The following example creates a window instance and defines a mouseDownOutside handler that calls a beep() method if the user clicks outside the window:
var myTW = PopUpManager.createPopUp(_root, Window, true, undefined, true);
// create a listener
twListener = new Object();
twListener.mouseDownOutside = function()
{
beep(); // make a noise if user clicks outside
}
myTW.addEventListener("mouseDownOutside", twListener);
UIEventDispatcher.addEventListener()
