| Implements | IWindow |
The Window container is a special kind of container in the sense that it cannot be used within other layout containers. An mx:Window component must be the top-level component in its MXML document.
The easiest way to use a Window component to define a native window is to
create an MXML document with an <mx:Window> tag
as the top-level tag in the document. You use the Window component
just as you do any other container, including specifying the layout
type, defining child controls, and so forth. Like any other custom
MXML component, when your application is compiled your MXML document
is compiled into a custom class that is a subclass of the Window
component.
In your application code, to make an instance of
your Window subclass appear on the screen you first create an instance
of the class in code (by defining a variable and calling the new
MyWindowClass() constructor. Next you set any properties you wish
to specify for the new window. Finally you call your Window component's
open() method to open the window on the screen.
Note that several of the Window class's properties can only be set
before calling the open() method to open
the window. Once the underlying NativeWindow is created, these initialization
properties can be read but cannot be changed. This restriction applies to
the following properties:
maximizableminimizableresizablesystemChrometransparenttype
Hide MXML Syntax
The <mx:Window> tag inherits all of the tag
attributes of its superclass and adds the following tag attributes:
