I have the following problem.
In my application I have several modules and each of them have components CollapsableTitleWindow (extends Panel). After opening the window it is added to the container which is in the main application (CollapsableTitleWindowContainer). In these windows you can open another window (and so on).
Now, what is the problem.
When I change (reload) any module and I want to open a new window (sub window) with the already loaded window I get this error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at mx.containers::Panel/layoutChrome()[C:\autobuild\3.2.0\frameworks\projects\framework\src\mx\containers\Panel.as:1405]
at com::CollapsableTitleWindow/layoutChrome()[D:\Flex 3 Workspace\WesobCrm\src\com\CollapsableTitleWindow.as:216]
at mx.core::Container/updateDisplayList()[C:\autobuild\3.2.0\frameworks\projects\framework\src\mx\core\Container.as:2867] (...)
Indicates that the main applications have object Panel
Please help.
P.S. I found a similar problem on http://www.nabble.com/Flex-Module-issue-with-Panel-td20168053.html
ADDED:
I extendes the Panel class and do something like that:
override protected function layoutChrome(unscaledWidth:Number, unscaledHeight:Number):void
{
use namespace mx_internal;
if(!(mx_internal::titleBarBackground is TitleBackground)) {
mx_internal::titleBarBackground = new TitleBackground();
}
super.layoutChrome(unscaledWidth, unscaledHeight);
}
But now i had something like that:
Before
(source: ak.bx.pl)
After
(source: ak.bx.pl)
You can see that it loos style declaration.
I found a solution but it is bad pratice:
I add in my main application
public function getProductWindow():ProductWindow {
return new ProductWindow();
}
And change in the module:
From
var productWindow:ProductWindow = new ProductWindow();
To
var productWindow:ProductWindow = Application.application.getProductWindow();
If anyone have a better solution ?

I have a window editor that holds nodes. I would like to open a custom inspector when one of these nodes is selected. The node class is a custom serializable class. Is this possible?.
It seems that custom inspectors can be created manually through the Editor.CreateEditor method but can't see how to let it appear docked like an usual inspector in the unity inspector window.
I would like to achieve the same behaviour that we have when we select a gameobject in sceneview that inmediately show properties for the object (Components, etc...) in the unity inspector.
Cheers
As I'm not sure what you're asking, here are multiple different solutions;
Selection
If you just want your nodes to become the focus of the hierarchy, then in your custom window's OnGUI method, use the code below;
[CustomEditor(typeof(NodeManager))]
public class NodeManager : EditorWindow
{
private static NodeManager window;
private Node[] m_nodes;
[MenuItem("Custom Windows/Node Inspector")]
public static void Init()
{
if(window == null)
window = GetWindow<NodeManager>("Node Manager", true, typeof(SceneView));
}
public void OnGUI()
{
m_nodes = GameObject.FindObjectsOfType<Node>();
foreach(Node node in m_nodes)
{
GUILayout.BeginHorizontal();
{
GUILayout.Label(node.name);
if (GUILayout.Button("Select"))
Selection.objects = new Object[] { node.gameObject };
}
GUILayout.EndHorizontal();
}
}
}
This adds a Button for each object in your custom window view, that will then select that object in the hierarchy.
Auto-Docking
I originally found the second response to this question, which goes into the details of parameters of the GetWindow method, and with this you can clearly see how to dock the window (I've converted it from JS to C# below).
(I looked fairly extensively in UnityEditor and UnityEditorInternal namespaces but couldn't find the Hierarchy or the Inspector).
GetWindow<T>(string title, bool focus, params System.Type[] desiredDockNextTo)
Which we can write for this example as;
EditorWindow.GetWindow<NodeInspector>("Node Test", true, typeof(SceneView));
This example docks the windows next to the SceneView window. This functionality can be combined with a custom inspector's OnInspectorGUI method, to automatically launch the custom node window, if it's not already open.
[CustomEditor(typeof(Node))]
public class NodeInspector : Editor
{
public override void OnInspectorGUI()
{
base.OnInspectorGUI();
NodeManager.Init();
}
}
Sorry if this isn't what you are looking for, if it's not then please give more details and I will amend my answer to better suit the question.
Hope this helped.
Has a possibility, you can make a custom ScriptableObject and Custom Editor for It, and when open the node inspector, just find a instance of the scriptable object and use Selection.selectedObject = scriptableObject, and in the custom editor, make a static field called 'editor' to draw inside.
It will work.
I have the following AS code.I have noticed that if an Application i s using the webcamera then it cannot be used by any secondary applications until unless the primary application is closed.
My question is that from the following code 1.can we capture that condition
2.If no camera is detected how to give the alert since it is an AS code
EDIT:
Filename is cldAS.as
Now how to call cldAS() from any.mxml file .Some example would be appreciated
package org.com
{
import flash.display.Sprite;
import flash.media.*;
import flash.net.*;
public class cldAS extends Sprite
{
public function cldAS()
{
var cam:Camera = Camera.getCamera();
if(cam != null)
{
cam.setMode(640, 480, 30);
var video:Video = new Video(300, 450);
video.attachCamera(cam);
addChild(video);
}
else
{
trace("No Camera Detected");
//How to give an alert here
}
}
}
}
Alert.show("You don't seem to have a webcam.");
instead of
trace(...) ?
Alert is available in Flex only , in AS3 you should really implement your own solution, on the other hand , since Alert is a Javascript function , you could also use ExternalInterface to call it.
As far as implementing your own solution is concerned, at the minimum you need a TextField to display your message, which text you could provide by sending a CustomEvent with a message property that will simply take a String. It wouldn't take too much work to create your own Alert class.It would sit on top of your App , you could toggle visibility when receiving a CustomEvent and have a Close button to hide it.
You should be able to call your AS3 class within script tags , other than that I'll leave a more detailed answer to Flex experts. I'm not sure if you can add a Sprite directly into Flex , for all I remember an object in Flex must inherit from UIComponent in order to be added to the stage but check with the other guys here, I haven't used Flex in quite some time...
<mx:Script>
import org.com.cldAS;
public cld:cldAS = new cldAS();
</mx:Script>
I'm getting a Flex ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller.
This is what I've got:
a) I set the variable lastButtonClicked to the last button that was clicked in the main app.
private var lastButtonClicked:DisplayObject;
private function lastButtonClickedFunction(event:MouseEvent):void {
lastButtonClicked = event.currentTarget as DisplayObject;
}
b) I have a TitleWindow open and there is a yes/no option. I have a custom event return the answer to the main app.
c) In the main app, I'm trying to remove lastButtonClicked based on the data sent by the custom event. So, my problem is in this function. For some reason it won't let me remove the button. I get Error 2025 instead.
private function answerHandler( event:AnswerEvent ):void {
if(event.answerCorrect == true){
removeChild(lastButtonClicked);
}
}
Any suggestions on how to debug this problem? The custom event is firing okay. How do I fix this line: removeChild(lastButtonClicked); ?
Edit: I tried hbox1.removeChild(lastButtonClicked) and it worked. The proper button was removed from the main app. The problem is that not all of the buttons are in hBox1. I've got other HBoxes. So, I need to figure out a more generic way instead of using hBox1 in the statement. I tired this.removeChild(lastButtonClicked), but it didn't work. Thank you.
Thank you.

From what I understand, it seems like you have the buttons in a TitleWindow and the event handler in the application. You probably want to call removeChild for the instance of TitleWindow (eg: titleWindow.removeChild(lastButtonClicked) ) rather than from the application.
I solved it. I made a variable and set it to the parent of lastButtonClicked.
private var myParent:Object;
myParent = lastButtonClicked.parent;
Then in my answerHandler I wrote:
myParent.removeChild(lastButtonClicked);
Thank you.

i'm loading a Flex Application in my AIR App and i'm using the childSandboxBridge and parentSandboxBridge to communicate between those two. Works like a charm.
But i've tried to load a Flash Application (the main Class extends Sprite, not Application) and therefore i get a SecurityError when trying to set the childSandboxBridge on the loaderInfo object.
In the Flex app it's like this:
I'm casting the loaderInfo since the childSandboxBridge Property is only available in AIR.
loaderInfo = FlexGlobals.topLevelApplication.systemManager.loaderInfo;
try {
Object(loaderInfo).childSandboxBridge = this;
} catch(e:Error) {
...
}
In my Flash app it's like this:
loaderInfo = myMainObject.loaderInfo; // myMainObject is the same class as 'root'
try {
Object(loaderInfo).childSandboxBridge = this;
} catch(e:Error) {
...
}
In the below example i get the following SecurityError:
Error #3206: Caller app:/airapp.swf/[[DYNAMIC]]/1 cannot set LoaderInfo property childSandboxBridge.
The SecuritySandbox for both examples is 'application'.
Any ideas why it doesn't work with the Flash app?
Thanks in advance.
You may need to explicitly indicate in Flash code that you will allow it to be loaded into another VM. Check out the flash.system.Security class documentation for details:

I am creating a canvas in actionscript like :
private var cvs_preview:Canvas = null;
private function show_preview():void
{
this.cvs_preview = new Canvas();
this.cvs_preview.id = "cvs_preview_1";
this.cvs_preview.setStyle('backgroundColor', 0x000000);
this.cvs_preview.setStyle('backgroundAlpha', 1);
this.cvs_preview.setStyle('borderColor', 0x417FDD);
this.cvs_preview.setStyle('cornerRadius', 10);
this.cvs_preview.setStyle('borderStyle', 'solid');
this.cvs_preview.setStyle('dropShadowEnabled', true);
var pt:Point = image.localToGlobal(new Point(image.x, image.y));
this.cvs_preview.x = pt.x - 50;
this.cvs_preview.y = pt.y - 50;
this.cvs_preview.height = 200;
this.cvs_preview.width = 250;
//this.cvs_preview.addEventListener(FlexEvent.CREATION_COMPLETE, get_focus_on_canvas);
//this.cvs_preview.focusManager.setFocus(
//this.cvs_preview.addEventListener(MouseEvent.CLICK, end_preview_on_focus_change);
this.cvs_preview.addEventListener(FocusEvent.MOUSE_FOCUS_CHANGE, end_preview_on_focus_change);
Application.application.addChild(this.cvs_preview); //add as top-most visible container
btn_mini_preview.enabled = false;
}
So on the focus change i want to run the "end_preview_on_focus_change()"
but this is not working.
As per my understanding, i think the canvas not getting any focus in the first place. I was trying to use focusManager.setFocus to do that after the canvas's creation complete. but even that is giving me an error.
the code i was trying on Creation.Complete is :
private function get_focus_on_canvas(e:FlexEvent)
{
focusManager.setFocus(e.target);
//Alert.show("testing img complete");
}
this is giving me an error "1118: Implicit coercion of a value with static type Object to a possibly unrelated type mx.managers:IFocusManagerComponent."
basically i just want to use the focus out event of the canvas.
Can someone help me with this...
I have been on this issue since a long time.

The error is correct. You have an object of type Object which you are trying to use as an IFocusManagerComponent. This will not work. To accomplish that line of code, you need to do something like
focusManager.setFocus( IFocusManagerComponent( e.target ) );
This, of course, assumes that the target implements IFocusManagerComponent. It will give you an error otherwise (and likely will in this case because Canvas is not listed as an IFocusManagerComponent). The good news is that Canvas does have a drawFocus method which will accomplish the same thing.
As to your MOUSE_FOCUS_CHANGE event, that will only be fired if an object already HAS focus and then loses it. I think you are better off using FlexEvent.CREATION_COMPLETE. This will ensure that the component has registered itself with all of the appropriate classes in the Flex SDK so that the FocusManager can even be aware of the new object. Whatever you do, do not try to set focus on something which has not been added to the stage (ie: Event.ADDED has been called).
As another piece of advice -- Event.ADDED bubbles, make sure that event.currentTarget == event.target to make sure that you are listening to the correct object. Otherwise, you might be calling the same function multiple times erroneously.
Only a few classes implement IFocusManagerComponent as others mentioned and Canvas is not one of them. If you really must call FocusManager.setFocus() you will have to extend the canvas class to implement this interface and use that class instead. You don't have to write any methods to implement this interface, all methods have already been implemented by UIComponent itself
//FocusableCanvas.as (include appropriate package and import statements)
public class FocusableCanvas extends Canvas implements IFocusManagerComponent
{
public function FocusableCanvas()
{
super();
}
}
//Now use this class instead of Canvas
this.cvs_preview = new FocusableCanvas();
//setFocus in creation complete handler
FocusManager.setFocus(IFocusManagerComponent(e.target));
But if all you want to do is to set focus on the canvas upon it's creation, you can call canvas.setFocus() from the creationComplete handler instead.
private function get_focus_on_canvas(e:FlexEvent)
{
Canvas(e.currentTarget).setFocus();
trace("done");
}
I see two problems, and no perfect solutions. With any luck, this can help you out.
First of all, e.target returns an object typecast with type Object. This explains your implict coercion error, because Object does not implement IFocusManagerComponent.
Second, iFocusManagerComponent is only implemented by Accordion, AdvancedListBase, Button, ButtonBar, ChartBase, ComboBase, DateChooser, DateField, HTML, ListBase, MenuBar, NumericStepper, TabNavigator, TextArea, TextInput, UIMovieClip as per this entry in the Flex 3.4 AS3 Reference.
This leads me to believe that a Canvas element cannot take focus and has simply inherited access to the FocusManager through inheritance of UIComponent.
The only solutions I can see are to utilize something other than Canvas to handle your focus related concerns, or subclass Canvas and implement iFocusManagerComponent, though that looks fairly complex.
Edit
Apologies for missing drawFocus in the above solution.
Please try;
private function get_focus_on_canvas(e:FlexEvent)
{
this.cvs_preview.setFocus();
}
