Flex :: Dynamic Object Layouts In Flash?
Sep 6, 2011
I have a general Flash question. I have got 2 .SWF wrappers (Playbook and Android,that work perfectly) that takes any .SWF file and wraps it up as an application. I'm hoping to make 1 application and have it run on both the Blackberry Playbook and any Android device.Technically everything is perfect but the problem I am having is with the layout.For example if an object is placed at x= 512 y=400 then it looks great on the Playbook but that looks horrible on an Android screen thats not 1024x800px. What I want to be able to do is something like (x=DeviceWidth/2), (y= DeviceHeight/2) so that it resizes and repositions itself automatically. An example of where I need to change the code is shown belowbt1.tween("_y", 400, 0.5, "easeOutBack");

I'm just finished my first month of getting to grips with flex. All of my projects so far have be very small fixed sized containers with everything in the application resting in an absolute position.The next up and coming project is going to require a more dynamic layout and need some advice.The app will consist of 3 container (not sure what ones to use yet)
Container 1Will be the entire width of the app and a quater of its height.
Container 2Will be beneath Container 1. It will be half the width of the app and 3 quaters of its height.
Container 3 will be the same as container 2.
I want to be able to collapse each container and have the other containers respond to this.For example, I would like to collapse container 1 so that container 2 and 3 go from 3 quaters height to 100% height.
If I collapse container 2 conatainer 1 remains the same but container 3 goes from half thes apps width to 100% of the width.

Virtualized Layouts are nice, but I find that they often feel a bit "chunky" due to the "tightness" of the virtual range. This could be improved by increasing the range - one or two steps ahead (and behind) would often be enough to improve the "responsiveness" of the list, especially when external resources (like images) need to be loaded.

Suppose you have a view, which contains three control A, B and C. The control A and B are in a HGroup, which itself is inside a VGroup with C.
Based on user interaction, I'd like to re-arrange the controls to new layouts. For example all three inside a VGroup. Or for example a layout, which hides A and B and maximizes C in size.
While I could hand-write the code, I'd like to use something like a layout template. A template, which contains placeholders for A, B and C. Give the current view, I'd like to pass the new template and the view should rearrange.

I was working on a project, copying and pasting a large amount of frames and objects when Flash CS4 would not let me save, the message was something like "cannot save due to an unknown error" so I closed it and opened again, and the following error popus came up repeatedly:
1) "The following panel layout is missing or could not be read:/Users/(my name)/Library/Application Support/Adobe Flash CS4/en/Configuration/Workspace/Animator.xml
The application will not have have a correct layout. Please load one from Windows - > Workspace."
2) " XML parsinfg fatal error: Invalid document structure lone: 1, files: Users/(my name)/Library/Application Support/Adobe Flash CS4/en/Configuration/Workspace/Animator.xml"
I looked for the file and it's actually in the folder.I've uninstalled and reinstalled Flash CS4 twice, and the entire Creative Suite once already, none of this has solved the issue.

I'm trying to get my main class to resize to the browser window size. I'm listening on the stage to Event.RESIZE, updating my width/height to match the stageWidth/stageHeight, and drawing a rectangle to show me how big it is. When I resize, it flashes between a small and big size every other time the event fires. The width and height are correct in both cases, but in the "small" case, everything is in a small box.

I have a dynamic Actionscript class as follows: public dynamic class Foo {....} In my code I (may) add some properties to it: myFoo["myNewDynamicProp"] = "bar"; Elsewhere in my code, given an instance of class Foo, how can I determine if that dynamic property has been added already without throwing an expensive exception?

I want to use the same movieclips (some are button movieclips) but be able to have a function lay them out at runtime in two (or more) layouts. Just the _x and _y position like in this example:I'd like to layout the mcs with just actionscript. So it can be hardwired into the movie's script with parameters A yielding layout A, et cetera.
something like this:
Code:
boxOne_mc._x = 100;
boxOne_mc._y = 100;
boxTwo_mc._x = 200;
[code]....
but all wrapped up in one function.

I want to create a generic component in flex. This component deals with different ArrayCollections dynamically (I want it in that way). So I thought to pass the arrayCollection and the type of that arrayCollection as arguments to the component.
Like,
var list:ArrayCollection<ClassA>;
init_Comp(list, "ClassA");
If it is possible, I can read it like this,
var newDynamicInstatnce: typeOf("ClassA") = list.getItemAt(0) as typeOf("ClassA");
Finally I have a Dynamic Instance type of that I pass. Is this possible in Flex or Is there a better way?

I have recently started working with Mahjong game. But being not so experienced developer. I am just confuse about many aspects of it. So if anyone could throw some light on it. I have to build the game where there could be different number of tiles on screen. 32, 48, 64 , 80, 96, 112 and so on Now I have questions regarding the levels of blocks in this game. I mean the layouts of the game should be predefined or they should be dynamically created? Also I wanted to know how the surface of enable and disable symbols are created?

I am using a regular Flash object as a simple data container, and I want to remove a particular property of that object. Then that object gets passed on to a for..in loop. But even after using delete to remove the property, the key still shows up in the loop.
For example:
var obj:Object = { a: "a", b: "b", c: "c" }
delete obj['b'];
for ( var prop:String in obj ) {
[Code].....
So deleting the property seems to be the same as assigning its value to null.
Is there any way to immediately remove the property from the object altogether so that it is no longer looped over in a for..in loop?
It is not sufficient to check the property for a null value since a property with a null value is not the same as not having the property in the first place, and represents a different state. I don't want to set the property to null, I want to remove the property.

We are developing our app in flash/flex builder for the front end hitting .NET backend webservices. There is one section of the old app that will not be initially converted, so we need have it appear in an iFrame.
So far all that works fine.We shrink the size of the SWF in the host page to just be the menu/nav area. And underneat that I have an iframe control that loads in this page from the old site.Now the problem. in the SWF is a drop down list to enable picking a client. Since the SWF has been shrunk to about 100px high, the drop-down will only occupy within that 100px area which it's opened. This is NOT good as you can imagine. How can I make the drop-down list descend over-top of the IFRAME control and thus extend outside the SWF dimensions? Is this possible?
I tried to make the internal stage transparent and leave the SWF a little larger, about 400 px high, but the IFRAME still appears behind the SWF.

i have a question while reading Flex 4 Cookbook i came across the method to dynamically adding control to the container controls but nowhere i came across with how to provide them with the dynamic properties and events like they have created a button dynamically inside a group control but what good a button be if i cannot give it an event dynamically. in the same way i want to add a tree view inside a vbox but what good that be if cannot provide a data provider to it dynamically.actually i am creating an web application where i add the tree view to a vbox and i want to the data provider should also be dynamic depending upon the option i have selected in the combo box.

I'm wondering if anyone has experience morphing an object from one skin/image/etc to another?What I want to do is have an icon morph into another image went it goes into a dragging state. Much like how icons morph into their widgets when you add widgets to the mac dashboard. Any way to get this to work would be helpful, including using the Flex 4.5 sdk or an external library for Actionscript.

Suppose I have a ViewStack like this:
<mx:ViewStack id="s" left="5" right="5" bottom="5" top="0" width="100%" height="100%" creationPolicy="all" minHeight="0">
<mx:Repeater id="repeater" dataProvider="{dp}" height="100%" width="100%" minHeight="0">
<mx:Box id="bx" label="{repeater.currentItem.label}" width="100%" height="100%" minHeight="0">
<mx:Label minHeight="0" width="100%" height="100%" label="bob" />
</mx:Box></mx:Repeater></mx:ViewStack>
With a large number of items in the stack (each having a large number of panels, databinding, etc), this gets extremely slow. The Repeater seems to trigger creation of all children regardless of the creationPolicy of the viewStack itself.

however I can not get it to work for some reason. What i would like to do is call an arbitrary component that extends Canvas. Since there may be a variety of components named TestCanvasA, TestCanvasC, TestCanvasC which i won't know till run-time I figured this would be the way to go about it. Here is what i have.

I have a bit of a memory leak issue in my Flex application, and the short version of my question is: is there any way (in AcitonScript 3) to find all live references to a given object? What I have is a number of views with presentation models behind each of them (using Swiz). The views of interest are children of a TabNavigator, so when I close the tab, the view is removed from the stage. When the view is removed from the stage, Swiz sets the model reference in the view to null, as it should. I also removeAllChildren() from the view.
However when profiling the application, when I do this and run a GC, neither the view nor the presentation model are freed (though both set their references to each other to null). One model object used by the view (not a presenter, though) IS freed, so it's not completely broken. I've only just started profiling today (firmly believing in not optimising too early), so I imagine there's some kind of reference floating around somewhere, but I can't see where, and what would be super helpful would be the ability to debug and see a list of objects that reference the target object. Is this at all possible, and if not natively, is there some light-weight way to code this into future apps for debugging purposes?

I've been trying to draw a series of points using a UIComponent using:
var line : UIComponent = new UIComponent();
...
line.graphics.lineTo(renderPoint.x, renderPoint.y);
[Code]....
The problem is that although I have all renderPoint segments etc. The line never gets drawn or it never gets displayed. I think this might be because of some Flex thing that is not so obvious.
