NativeWindow – using AIR windows with Actionscript (part 3 of 3)

In the first part of this post I covered each public property exposed by an instance of NativeWindow, before continuing to look at each public method in part two. In this final part of the series I’ll go through each of the different events dispatched by a NativeWindow during its lifetime.

Event.ACTIVATE

This event is sent out when the window is activated. The event doesn’t go through a capture phase, and it won’t bubble up the Display List. Some examples of when your window may dispatch this event include:

• When the NativeWindow is first created and activated
• When your application contains multiple NativeWindows and the user clicks on a window which previously was not the active window, giving it focus and bringing it to the front, the window will dispatch Event.ACTIVATE
• When you switch to another running application elsewhere on the system (an AIR application, or otherwise) and then switch back to this window, the event will be dispatched

NativeWindow – using AIR windows with Actionscript (part 2 of 3)

In the previous post I listed the public properties exposed by an instance of NativeWindow. In this post, I’ll be going through NativeWindow’s public methods. The third and final part of this series will explain the Events dispatched by a NativeWindow during its lifetime.

Once a NativeWindow has been created, you can call methods to move, resize, reposition, activate and close the window. All these methods are fairly simple, with the odd gotcha thrown in for good measure. So, here’s a description of each of these methods…

NativeWindow – using AIR windows with Actionscript (part 1 of 3)

In a previous post I described how to create and activate an application window when creating an Actionscript AIR project in Flex Builder 3. I then went on to describe in a little more detail the various properties of the NativeWindowInitOptions class, and how setting some or all of these properties can affect the style and behaviour of the window that will be created. I guess the final step is to describe how to work with the window once it has been created, starting with an explanation of the flash.display.NativeWindow class. There’s quite a bit of functionality contained within the class, so I’ll break this post up into three. Part 1 will describe the properties of a NativeWindow, part 2 will list the public methods and finally part 3 will discuss the events dispatched by the Window throughout its lifetime.

As previously mentioned, an application window is created and displayed in Adobe AIR by creating a new instance of the NativeWindow class, and then calling this instance’s activate method. Content is added to the window by adding DisplayObjects to the stage property of the NativeWindow instance.

Here are descriptions of each of the NativeWindow’s public properties…

NativeWindowInitOptions – configure your AIR NativeWindow

In a previous post I listed some code to create and activate a NativeWindow in an Actionscript AIR project without really explaining what was going on behind the scenes. In this post, I’ll explain a little more about the NativeWindowInitOptions class, and how you can control the appearance and behaviour of the NativeWindow that you create.

The code I used in the previous post was this:

Fairly obviously, the NativeWindow constructor accepts an instance of NativeWindowInitOptions as its first parameter. In the previous example, I’m not doing anything fancy with the NativeWindowInitOptions instance that I create, I just create a new instance of the class and pass it to the NativeWindow constructor. As a result, all the various properties will have their default values, and the NativeWindow will be totally default. How terribly dull. Here’s a list of properties of NativeWindowInitOptions that you can play with to control how the NativeWindow will look and behave when it’s created….
