Hi folks,
I'm working on an AIR app that lives in the system tray / dock. It
should not have a visible window at startup, only a system tray icon.
After some event, I would like to create one of two windows (depending
on the event). I've got the system tray part working, but can't get the
window to open...
TrayApp.as:
class TrayApp extends Sprite
{
// .... etc ....
function processEvent()
{
var wnd:Window = new MyWindow();
mywindow.open();
}
// .... etc ....
}
MyWindow.mxml:
<mx:Window xmlns:mx="http://www.adobe.com/2006/mxml"; width="400"
height="300">
<mx:Label text="hello, world"/>
</mx:Window>
When I run this, I get an exception deep in UIComponent:
TypeError: Error #1009: Cannot access a property or method of a null
object reference.
at
mx.core::UIComponent/http://www.adobe.com/2006/flex/mx/internal::updateC\
allbacks()[C:\autobuild\3.2.0\frameworks\projects\framework\src\mx\core\\
UIComponent.as:5124]
I suspect that maybe I can't call the open() of Window from my app that
extends Sprite because some of the application framework is missing
(like layout managers, etc..). Maybe it has to extend
Application/NativeApplication instead? I tried that, but got another
odd exception.
Anyone know how to do this?
Thanks,
Mitch.
