[flexcoders] Re: Increasing the Panel scroll speed?

Hi,

You can use these two properties to control scroll speed;

container.verticalLineScrollSize
container.verticalPageScrollSize

Re: [flexcoders] Re: How do arguments to an AS3 class translate to MXML?

[Michael Schmalle]

This wasn't a personal challenge. I didn't say you were wrong, I noted that
the mxml interface method had a d on the end. I then said UIComponent has
an initialized property like the method in the mxml interface.
Writing emails to a forum is kind of relaxing compared to the rest of the
day. Maybe you should ask me to clarify better before adding paragraphs
unrelated to what I was trying to convey.

If I interpreted the question wrong and you can see it (leading a developer
down the wrong road), try to clarify the misinterpretation with a question.

Re: [flexcoders] Re: UI component, a set function & creationComplete

[Michael Schmalle]

Amy,
I have read all that you have written. 2 years of sales, no complaints on
the algorithm I use.

> So it very much matters where you create children when _other people_ are
going to be subclassing your work.

I have created a sub template in commitProperties(); That can
be overridden from any subclass since it separates operations into hooks.

1.

public function set titleBarRenderer(value:IFactory):void
{
if (_titleBarRenderer != value)
{
_titleBarRenderer = value;
titleBarRendererChanged = true;
invalidateProperties();
dispatchEvent(new Event("titleBarRendererChanged"));
}
}

2.

override public function commitProperties():void
{
super.commitProperties();

if (titleBarRendererChanged)
{
commitTitleBarRenderer();
titleBarRendererChanged = false;
}
}

3.

protected function commitTitleBarRenderer():void
{
 createTitleBar();
}

4.

protected function createTitleBar():void
{
_titleBar  = PartFactory.createComponentPart(
TITLE_BAR_NAME, this, rawChildren,
DisplayObject(_titleBar));
}

5.

tk_internal function partAdded(name:String, instance:Object):void
{
if (instance == _titleBar )
{
    configuration
}
}

As far as not releasing code, this next iteration of products will have
source code, but the template is still the same.

I hear you on the "I listen to respected developers on this list" but, this
way works even better than how the framework is set up (for subclassing).
Adds more method calls but, it's impact is irrelevant since these calls are
not 100 every minute. I also use this template for other properties that are
not processor intensive or called to frequently.

Regarding

For future reference, IMXMLObject implemented as3 classes cannot have
arguments in their constructors.

As josh said, just shift your constructor logic to a setter and treat it as
if it were an argument.

Note ::
The IMXMLObject method signature is (d);

initialized
(document:Object,
id:String
):void

the UIComponent's initializer is not initialized(), it's;

initialize():void

The UIComponent.initialized is a property not a method.

Clarification;

Since we all design software with a design, any property committal in a
super() call has nothing to do with an instance of a child you create in the
subclass (this is bad design). Thus, the above logic holds true.

Re: [flexcoders] Re: UI component, a set function & creationComplete

[Michael Schmalle]

well big mouth has to say one more thing,

Imagine commitProperties() committing property states :) , all of your
properties have been committed. Children can be created at any time AFTER
super().

What you fail to see is commitProperties() is a glorified createChildren().
This only thing "cool" about createChildren() is Container calls
createComponentDescriptors() which is a heavy method.

Other than the above, commitProperties() ALWAYS runs before measure() and
updateDisplayList() so there is never a problem with creating children in
commitProperties().

But subclassing a UIComponent, give me a break. I was under the impression
from Eric's post that his "issue" was more than just create the children in
create children, why the hell would I tell him to circumvent a template
method!?

Sorry, your post felt a little personal.

Re: [flexcoders] Re: UI component, a set function & creationComplete

[Michael Schmalle]

Hi Eric,
> So, my question is does your approach address this by creating children
in
commitProperties()
Yes,

This is basically what I do with all renderers in my commercial components.
I rarely use createChildren(). The only time I use createChilren() is when
the composite is 100% owned by it's parent containing the creation code.

commitProperties() will solve all timing issues if implemented correctly.

I'm not quite sure I get what you are asking in the second half but, all
item renderers use this algorithm which their state is entirely dependent on
the data being pushed into the component either through data or public
accessors.

This means that children will not be instantiated until the data is present
for their instantiation.

If this doesn't make sense, try to clarify a bit more.

Re: [flexcoders] Flex builder annoyance - library projects

[Michael Schmalle]

Hi,
I can say ANT is your answer, build the SWC using it. I have very complex
libraries, and all I maintain is a simple ant xml included file (that is
imported from the master build file, this includes multiple project library
builds at once) that lists the front end class clients, the linker resolves
the rest.

This way you can checkout and commit these files in collaboration.

Re: [flexcoders] Re: Daily WTF..." Property top not found on mx.containers.HBox and there is no default value."

[Michael Schmalle]

Yup, thats right.
Sorry I didn't mention these things, but the puff ball on crack, that is
original.

I'm sure in future versions there will be even more puff balls
to distinguish from. The Java perspective is awesome when it comes this
stuff, but Flex code analyzation has a ways to go.

Hi,
Whenever in doubt always look at the asdoc's before hitting critical mass.
:)

Also, Flex Builder uses icons next to code completion that give you the type
of member as well (event, effect, style or property).

Re: [flexcoders] Re: Programatically skinning a container, but what to do about the nested children?

Hi,
Try subclassing RectangularBorder instead, then you can override the
borderMetrics property and set it based on how much right offset you need.

Re: [flexcoders] Re: Gosh what a state to be in..

[Michael Schmalle]

So are you talking about a state machine table implementation with push -
pop based on the tables setup?
IE you can only push if the context is "this" and you can only pop if the
context is "that"

This would definitely allow sub-sub states very easily and allow restriction
in these sub states. I use this algorithm in an as3 parser.

Re: [flexcoders] Finding out the size of a component when everything is relative?

[Michael Schmalle]

Hi,
The properties with $ signs mean they are wrapped and mx_internal. The
$height and $width are the actual Flash Player version of height and width.

At what point are you trying to get the height and width? Do you know for
sure the canvas has children and has been measured and updated?

If you can see the canvas (with children), there is no way the width and
height will be zero. The borderColor property help with debugging to
actually see the canvas if it has no borderStyle, set to solid.

'is' tests an instance to a class reference. I was thinking in the opposite

Re: [flexcoders] Re: Equivalent to Java's Class.isInstance(Object) instance method?

[Michael Schmalle]

Adding to the insight, if you wanted to use the 'is' operator with those two
arguments, you need to create an instance of the Class and then use the 'is'
operator.
This would let you know if it is an instance of the object passed.

public static function
isObjectInstanceOfClass(obj:Object, cls:Class):Boolean
{
return obj is new cls();
}

We have asked the player engineers about the performance hit on this is not
as bad as describeType in some instances.

I have no comment on the issue since this comes up on flexcoders about every
other month but this statement is what I was telling myself when reading
some of these posts, this has been the only fact given.

My analogy is nature has it right, mankind seems to love trends and
affiliations (we seem to need identities).

A tree has been a tree for as long as trees have stood on the earth. Nature
made trees as a tool, to regenerate oxygen so the earth might live just a
little longer.

I can see it now, in another dimension the deciduous hate the conifers and
the conifers hate the deciduous.

Re: [flexcoders] Re: Still no one knows ? Please help.

[Michael Schmalle]

Amy,
I don't know if what I said was the 'correct' way. But he wanted his bullet
color to be the same as the text color, so using the color style seemed
right.

As far as the styleName being null like he said, I haven't looked into that.
That was what this last post was concerning.

I'd have to look at the Menu - MenuItem code to see what is really going on
when the menu item is created.

Hi,
Since you are using an itemRenderer, this could be tricky. You need to find
out where the parent is (MenuItem instance) and cast that reference to
IStyleClient.

IE

var color = IStyleClient(parent.parent).getStyle("color");

Re: [flexcoders] dividerSkin problem

[Michael Schmalle]

Hi Guy,
There is no logic in the divider container that checks the minimum width or
height of the dividers relative to the size of their container.

I don't think this is to weird on Adobe's part since they usually have a
policy (unwritten) that chrome is not part of the measurement algorithm. The
dividers are considered chrome and exist in their own UIComponent layer .

You probably could subclass and add this measurement but it's not that easy
since the DividedBox by nature does not like calling measure(). They do this
for performance and relates to their layout implementation.

Yes, of course it can be reused, the type can't change. Which this is not
the case since you are suing Button for all 20 instances.

You can do;

b1 = new Button()
addChild(b1):

b1 = new Button()
addChild(b1):

b1 = new Button()
addChild(b1):

as many times as you want. It's getting the instances back that you need to
plan for.

As far as retrieving them, as Tom said, and array object hash, or
dictionary.

Re: [flexcoders] Re: Still no one knows ? Please help.

[Michael Schmalle]

Hi,
Use a ProgramaticSkin subclass.

Then use the method drawCircle() to draw the circle based on the value of
getStyle("color"), which is your text color of the parent.

Pseudo;

override protected function updateDisplayList(w:Number, h:Number):void
{
var color:unit = getStyle("color");
var g:Graphics = graphics;

g.clear();

g.beginFill(color, 1)
g.drawCircle(0, 0, w, h);
g.endFill();
}

You can create a bindable model class, the bind this classes popupText to

Hi,
I see what you r problem is now,

You need to change these icons (styles);

radioIcon, radioDisabledIcon, checkIcon, checkDisabledIcon.

You see the default.css is;

radioIcon: Embed(source="Assets.swf",symbol="MenuRadioEnabled");

That will solve your problem.

Re: [flexcoders] mouse wheel behaviour mxml and actionscript based components

[Michael Schmalle]

Hi,
Usually the reason for no mouse wheel events is a lack of background color.

Can you give some examples (mxml/as) of what 'doesn't' work for you?

Anyway, you need a background color for the control to broadcast mouse
wheel events.

Other than that it's just a guess what the problem could be without an
example.

Re: [flexcoders] Are my eyes painted on, or is FormItem not available in design mode?

[Michael Schmalle]

Hi Josh,
It's hard coded into the Flex Builder java code. They figured since they
thought it only needed to be in a form that they would remove it from the
components panel (hard coded) and add it majikly when a designer dropped a
control into a form (container).

Seems like this is creating your own reality and I myself really don't like
these kind of hard coded aspects of flex builder. There should be a
preference to enable-disable this type of functionality, disabled from the
start.

Re: [flexcoders] Re: Resizing a class file

Hi,
Your looking at the problem wrong.

You never assign an instance to a Class variable type. You need to create
another variable at the class level to hold the new instances that are type
Image.

functiontoGetImage() are you returning an instance or a Class to
instantiate?

Re: [flexcoders] Re: Resizing a class file

[Michael Schmalle]

Hi,
It's more like you have to create an instance.

The Class is an actionscript type like Boolean or String. This is like
asking can you write Boolean.value = true;

Try;

override protected function createChildren():void
{
super.createChildren();
instance = new myIcon();
instance.width = 25;
addChild(instance);
}

Re: [flexcoders] Which style name control the color

[Michael Schmalle]

Hi,
It's the 'iconColor' style.

These are available for the checkbox;

borderColor, iconColor, fillAlphas, fillColors, highlightAlphas
and themeColor.

Re: [flexcoders] Creating custom components in flex using actionscript 3.0

[Michael Schmalle]

Hi,
I see two things that need to be changed in your code;

1. When setting setStyle() you need to use the correct style type. You are
using strings for numbers IE "2", this is not correct and could cause weird
behavior, change this and see if you still have your issue.

2. In your commitProperties() override, you need to create a flag so you are
not calling setStyle() on each property invalidation.

- you don't need this line either; this.creationPolicy = "all";

To clarify, it's the outer box that you don't want scrollbars on?

Re: [flexcoders] Re: how to add internal padding in canvas?

[Michael Schmalle]

The irony to all this over analyzation is;
We never heard the OP say WHY he even wanted to do this (padding in Canvas)
let alone if he even needed a canvas to do what he needed to do!

I just need to stay out of these application questions. ;-)

Tim, It is really exciting to see the future of flex and CSS.
I definitely encourage using things that deal with styles since the
framework is going to tip that way soon anyway. This is in reference to
using constraints.

I see loading style sheets as modules sooner than later. :)

Re: [flexcoders] web compiler

[Michael Schmalle]

Ok,
I had this in my plans to investigate in a couple months for my server.

So is there something that caches swf on the first run, then only recompiles
when the mxml has changed?

Where did I hear that? This is in my head from a year or two ago.

Re: [flexcoders] Re: how to add internal padding in canvas?

[Michael Schmalle]

Tracy,
Container::getScrollableRect():Rectangle

uses usePadding,

Dumb answer on my part. I had to subclass canvas where I actually wanted the
padding to count in the scrollRect.

Sorry for the noise, I'm thinking to much these days. I agree, from a design
perspective there is no need to do what I said.

But for the sake of an explanation, usePadding has to do with the
contentPane and how it gets shifted when there is scrollable content, so
overriding that would give you padding even though your component is at 0,0
in the contentPane.

Re: [flexcoders] how to add internal padding in canvas?

[Michael Schmalle]

A hack that can be done if you really want Canvas is;
Create a subclass of Canvas and override the usePadding property.

override mx_internal get usePadding():Boolean
{
return true;
}

This will turn the padding back on when the
layout calculates viewMetricsAndPadding.

Re: [flexcoders] Re: Extending UIComponent memory issues.

[Michael Schmalle]

Jason,
What I suggested is probably a bit to complex for what you need. It's kind
of a reimplementation of what you are doing.

1. Subclass UIComponent to make your container.
2. Create the layout algorithm in that component.
3. Create a subclass of FlexSprite that is your loader component.
4. Add the FlexSprite subclass instances (your content) to your UIComponent
container class with custom layout.
5. Add the UIComponent class to a Container.

The above is not really a solution for you right now I'm sure, I was just
saying this is what I would do to get maximum performance and memory
management.

The reason I say this is I have no idea how you are laying out those
instances with reflection etc. How are you laying them out (with what layout
algorithm) ?

Re: [flexcoders] Re: Efficiency and objects in the display list

[Michael Schmalle]

One correction on my part.
It's IUIComponent that is important. IFlexDisplayObject is for skins so you
can call move(), setActualSize() and get a measuredWidth and measuredHeight
from them. The allows for the polymorphic behavior when laying out skins and
components. Your code can see the same thing and does not have to
differentiate between a component or skin (Shape).

The IFlexDisplayObject gives an impression of the core DisplayObject as
well.

The ILayoutManagerClient interface allows the layoutManager to use nesting
and call validation on the components in the queue.

Re: [flexcoders] Re: Efficiency and objects in the display list

[Michael Schmalle]

And to put the icing on the cake...
The deal is the LayoutManager loves the IUIComponent interface which has
another buddy called IFlexDisplayObject.

IFlexDisplayObject is instrumental in coupling measurements plus nesting
levels that the layout manager needs to do it's queue sorting when laying
out display objects.

Navigators need Container children because Container is hard coded into them
all. :) They have implemented IContainer and added some members to it. I
hope they get all these concrete references out of the framework eventually.

If the Flex framework is going to be really successful in the long run,
everything needs to be renderers/factories and interfaces. I got three years
on riding Alex's coattails in this area. ;-)

Like how about IScrollContainer... this is in my framework now.

Re: [flexcoders] Override mx:Window close function

[Michael Schmalle]

Hi,
If I remeber correctly, you need to listen for window closing event and call
event.preventDefault().

This will stop the default behavior and then allow you to hide the window,
setting the visible or whatever implementation you have.

Re: [flexcoders] Re: Extending UIComponent memory issues.

[Michael Schmalle]

Doug, Jason,
Since I am a self-centered person that doesn't like to be misunderstood,
;-), I could have brought up the 4000 object issue. In previous threads with
Jason, he said this was a requirement from the higher order. So I left it
where it was, 4000 objects.

As far as the IUIComponent issue, it is Container that requires them not
'Flex' itself.

This is where as flex projects, Web 2.0 and performance are reaching a point
where it's not just making a Flash IDE animation anymore.

When the requirements of these projects come to this level there is more
engineering involved and Flex out of the box is not going to handle
situations like this.

The absolute way to do this is creating a UIComponent subclass that is the
container, creating your layout algorithm in this component. Subclass
FlexSprite, make that your content loader component.

Then instantiate the content components in the UIComponent container. This
is the lean version of your design I envision. You could even recycle the
content renderers in your container component Lot's of things you could
do ;-)

Re: [flexcoders] Extending UIComponent memory issues.

[Michael Schmalle]

A side note,
You are doing some very expensive leg work in the 'content' setter.

You need to break that out into commitProperties() and updateDisplayList().

You would get a huge performance increase for sure.

As far as the memory, doesn't look to weird, event listeners without weak
references can make thing hang around as well.

Hi Amy,
No, the metadata is what instructs the compiler to add style definitions and
[Style()] meta is not allowed in an interface.

Needs to be done in the class package definition.

Re: [flexcoders] Re: Create Help System in Flex - how to display html in a canvas or component?

[Michael Schmalle]

I'm writing a component that will integrate help in applications using the
DocBook xml format and an as3 parser -> ui converter. This is coupled with
an asdoc generator application.
Patterns are based of of Eclipse's help system framework.

I think I might release this open source some day.

Screw HTML.

Amy,
A flex theme is just a SWC file.

Use the -theme compiler flag and add it to the options. Why would this be
silly? Probably would take me the time it took you to write that paragraph.
;-) But I don't have the theme.swc sitting in my test project, so add 1 more

I second that!

They make you become creative... add scale and rotation together, the IEEE
floats start to float away.

Re: [flexcoders] Where is Alex Ahauri??

[Michael Schmalle]

Hi,
He was on vacation for over a month.

If I was him, after that long of vacation not doing anything job related, I
would be enjoying programming in flex again. I bet that is what he is
doing... enjoying his work again. :)

I'm sure you will see him around. Personally, I can't see how he can answer
so much when he still has his framework engineering to do.

Ah never mind about the generated, just checked.
I thought I saw somewhere, where a dev actually accessed the real method
that the compiler creates.

Re: [flexcoders] using callLater with setter?

[Michael Schmalle]

Yeah, I understand.
The problem as you know is they use apply() so you need the real name of the
setter when flex compiles it. I thought they uses 'setSelectedChild', I
tried that and it was not defined.

Maybe keep generated as could show something.

Re: [flexcoders] Interfaces WHY?

[Michael Schmalle]

> But in general I think implementation inheritance is over-used and

WORD!

Especially in UIComponent designs, I would discourage the use of extends
with interfaces.

It's a lot easier if your class just implements what it needs and leave
the inheritance to the class framework that is implementing the interfaces.

This is not to say don't, but careful design of User Interface interface
frameworks is needed. Adobe did a pretty good job at this.

If you were around in the Flex 2 betas especially the alpha you saw how
the scrubbed the interfaces and completely refactored out
some inheritance they used in the interface framework.

Re: [flexcoders] Interfaces WHY?

[Michael Schmalle]

Hi,
It's ICommand.

The reason is you can stack interfaces on top of each other allowing more
decoupling to the implementing concrete classes.

This interface is obvious. Any class that implements it needs eval() and
only eval. It's like a singleton declaration of implementation.

If you jammed this evel() method into IUIComponent, maybe all components
don't need eval. Make sense?

Also another good example of this type of interface in the flex framework is
IDataRenderer, it's only declared property is 'data'.

Re: [flexcoders] Screen freezes when running code in result callback function of HTTPService

[Michael Schmalle]

Hi,
This is a single thread problem. The problem is you are parsing data that is
taking that single thread the Flash Player uses to do all of it's work.

The solution is to batch your xml parsing into a timer queue of sorts,
dispatch an event to the progress bar updating the batch total to completed.
Then your screen will not lock up either.

I have done this with quite a bit of things, batching definitely works. You
as the developer need to figure out how to abstract the parsing into chunks.

Re: [flexcoders] Re: set height of a Container back to default? (resize to content)

[Michael Schmalle]

Hi,
This is not right... throwing an error.

Can you post the error?

The hack your co-worker gave you is definitely unnecessary.

Can you post some code that will reproduce what you are trying to achieve?

Setting the container's height = NaN will force the container to ditch the
last height metric. When this happens the container invalidates it's size,
thus calling measure(), remeasuring child preferred widths and heights.

On the next validateDisplayList() call the layout manager will then set your
container to it's measuredHeight since there is no explicit height set.

I need to know the error you are getting.

Mike

Re: [flexcoders] Real canvas height and width

[Michael Schmalle]

Hi,
When you explicitly set the width OR height of a component, the measure()
method will not be called since you have already "locked" in the dimensions
of the component canvas.

Use this method instead

v1.getExplicitOrMeasuredHeight()

You will see it traces your set height.

Now, take out the height and width assignments in MXML and you will see that
it now traces;

Height: 32
Measured Height: 32

You Do have a mismatch brace

Right where the wrong is.

Should be...

Re: [flexcoders] Re: How to make a Docking Window Framework/component like Eclipse/InfoDock/JDock

[Michael Schmalle]

Yeah, I forgot about that.
There are probably 20 different ways you could implement something like
this. From my experience you want to start out thinking abstraction and not
program to much into your views.

@Josh
Well buddy, this dads gotta make money for the little people in his house
but, since you are one of the groupies around here, I could use some beta
testers and then flip you it for free (for your time ;-)

@Tim

Thanks, and these frameworks were designed with love. If you look at my
blog, it looks like I died or got abducted by aliens. Really, I have been
working hard on something I could finally feel comfortable saying this could
be around for 5+ years.

Coming up;

Windowing Framework
Transformation Framework
View Framework
Docking Framework

The windowing framework plays a major role in anything I do from here out.
The framework will cross pollinate with AIR. I also borrowed some design
patterns from eclipse that abstract window implementation from the actual
view component itself. This is the first one I'm releasing. Plus this time I
am selling the source code as well.

Re: [flexcoders] How to make a Docking Window Framework/component like Eclipse/InfoDock/JDocking

[Michael Schmalle]

Hi,
No need to cross post from flexcomponents to flexcoders most of us read
both.

This is a bit of engineering on your part. This is like asking where do I
start to make a space ship. There are so many details, you will need to
design this from your knowledge of flex components.

You might look at the flexlib and it's MDI implementation. That might give
you some ideas on where to start.

Ironically, I am releasing a framework like this in 2 months. Truth be told,
I have spent 1 1/2 years creating a base framework that made it happen.

Re: [flexcoders] any way to integrate 3rd-party help into FB?

[Michael Schmalle]

Hi Jason,
Eclipse plugin project with a plugin.xml like






   
  
  
   




This is the only way you will get it to show up as a 'book' in the FB help.

I've done it and it works great, you can even create an update site, that
can keep the docs fresh.

You need the PDE plugin to create a plugin. I use a different version of
eclipse (not FB) to create plugins.

See the Creating a plugin using the help extension point (in the PDE docs).
 This might be worthy of a blog post someday. :)

I can't believe a UIComponent is killing your performance that bad, I would

Re: [flexcoders] component reuse

[Michael Schmalle]

Hi,
SWCs have nothing to do with loading and runtime. An SWC is a collection of
abc bytecode that gets compiled into a application with the mxmlc compiler.

You have to create the rsl from an SWC with the compiler.

No, SWC have to be compiled with the mxmlc compiler into the app.

RSLs can lazy load component libraries though.

Hi,
If I remember right, that class mixed in styles and other prototype
functions. I might be wrong, the version 2 framework seems like such a long
time ago now. :)

That class no longer exists.

Are you going to use the HaloBorder in Flex 3? You really shouldn't have a
problem. Post some code that you are having a hard time converting.

Re: [flexcoders] The Tree component sux but .... I need help :)

[Michael Schmalle]

Matthew,
The Tree component doesn't suck that bad, try a different title.

I'll answer your question though, openItems uses references(unique id's),
it's not majik man. You have to understand instance references, then you can
say the Tree doesn't suck, I just didn't understand it.

This is the key, right here;

_openItems[itemToUID(item)] = item;

What this means is, if you do not supply the items with the same
instance(unique), this property will never work.

Sounds like you need to do a little leg work and save the state of your tree
before you set the dataProvider, then create a new openItems Array with the
current instances that ARE IN the tree.

What kind of objects are held in your dataProvider? ... Object, or a custom
model class?

Re: [flexcoders] Module vs Application

[Michael Schmalle]

I'm no expert on this but, I would say memory/design principles.
A module extends LayoutContainer, where as Application is the whole shabang.

Loading multiple Application instances into another Application using
SWFLoader is bound to take a lot more memory.

I think compilation of modules directly relates to how you 'design' your
main application's architecture.

Think about this, if you can design modules in a way that encapsulates what
changes into 'modules' and keep logic out of them that doesn't, compilation
will speed up.

I'm really talking about class architecture, using factories, getting 2 or 3
levels of abstraction. This is what I do and it works well.

Re: [flexcoders] Dimensions of a UIComponent are allways 0, 0?!

[Michael Schmalle]

Hi,
Search the archives for this, I know I have explained it quite a bit. :)

If you can't find it there read up on "Creating Custom Components".

You problem has to do with the fact you have not overridden measure() and
set measuredWidth and measuredHeight of you component.

If you don't do this, the layout manager will set the size of your component
to 0,0.

Re: [flexcoders] Error when PopupManager hides a popup in the middle of an effect

[Michael Schmalle]

Hi,
That is an interesting error. Basically it's telling you that the tween for
the actual effect got de-referenced somehow.

two places that could happen;

end()

and onTweenEnd()

Can you get a simple example to reproduce this in mxml? ... Quick little
application.

If I understand you correctly, thats not the point (reading the

Re: [flexcoders] getItemAt *removes* item from ArrayCollection?

[Michael Schmalle]

Hi,
Sounds like you need to check your bindings.

I don't think there is any way possible that the ArrayCollection can become
intelligent and start deleting items without being told to by some outside
force. ;-)

Sounds like it has to do with the;

flightToMarkAsRemoved.flightHasBeenClearedByUser=true

That would be my guess.

Re: [flexcoders] Re: Retry: Question for Doug McCune on Drag-drop component?

[Michael Schmalle]

Hi,
The reason it simple, with 3 event handlers you can control everything about
your custom dragging and/or dropping you need.

The drag manager has flaws, trust me I made a docking component and almost
ditched the manager but I had to use it since I didn't have the time to
rewrite it.

Think of it as capturing each user gesture individually, you cannot do this
with the DragManager.

Re: [flexcoders] Speeding up draw time with nested VBoxes

[Michael Schmalle]

Jason,
> values 'y="{something.x + something.y}"'

Avoid bindings at all costs. When you create a binding expression, it adds
many more calls to the stack during runtime. Not saying there bad, but here
again, they need to be used in the correct places.

commitProperties() is your friend. If you are creating a custom component
that needs to 'perform'  IE itemRenderer, do it in actionscript, you will
always make out better in the end and it's more maintainable.

Until there is greater code creation optimization from the mxml compiler,
binding adds weight and stack calls, it's definitely not free.

Re: [flexcoders] Re: Getting multiple addedToStage events

[Michael Schmalle]

> Event.REMOVED

Containers cannot use this since their child list is not updated.

UIComponent listens to the Event.REMOVED and stops propagation of it so
there is no way to listen for it. The component will then dispatch
FlexEvent.REMOVE at the correct time after child lists are correctly
situated.

This is what I was trying to say in my original comment to the OP. I used
CHILD_REMOVE, CHILD_ADD but FlexEvent.REMOVE and FlexEvent.ADD is the same
really except backwards.

Wow, this is freaky, I love reading your constantly changing signatures. :)

Re: [flexcoders] Speeding up draw time with nested VBoxes

[Michael Schmalle]

> plus I have a grudge against vboxes now :P
It's not the gun that kills but the finger that pulled the trigger... ;-)

VBoxs serve their purposes and perform great when they are used 'correctly'.
I know that sounds bad but I don't mean it like that.

There are while(loops) in the layout code that acts like a circular saw,
when it's grinding it's taking A LOT of energy from the Player, the large
the wood, the more power it needs.

The plus side is, since the algorithms are so good in it, with controls that
have limited children and layout logic, there is a lot you can do with boxes
(stretching).

But Tracy is totally right, item renderers are what you need. I think this
will change  in the future, the way developers look at 'renderers'.
Renderers abstract and decouple your repetitive layout and child creation
code from the main component controller. You can then at any time in the
future optimize a renderer of any kind easily and efficiently.

Re: [flexcoders] Re: scale9Grid: What am I missing?

[Michael Schmalle]

Ok,
I think that needs to be without quotes but Jon is probably right, you need
to try setting some sort of height.

When you get it working, try it with the quotes, then you can be sure. :)

Re: [flexcoders] Re: Scrolling screws up display

[Michael Schmalle]

Hi,
I have had this happen before but I was messing around with the contentPane
(low level stuff).

Can you post something semi simple to reproduce this?

Hi Amy,
I remember something weird about this, try loosing the apostrophe's around
the numbers.

[Embed(source='images/window.png', scaleGridTop=40,
scaleGridBottom=185, scaleGridLeft=300, scaleGridRight=585)]

Re: [flexcoders] Questions on AIR and Flex Builder

[Michael Schmalle]

> I know that there's an Apollo list, but I don't want to subscribe for a
couple of questions.
That just sounds funny. ;-)

1. Do you have a semi-simple mxml/as setup that shows this or is application
pretty large?

2. Give a procedure of what you do, I could see if it messes up in mine as
well.

FlexBuilder 3.0.1 right?

Re: [flexcoders] systemManager & PopUpManager & Alert window

[Michael Schmalle]

Hi,
This is because the popup manager puts the POPUP instances at a different
space in the systemManager IChildList (above all parent popups).

When you create your popups, can't you create a map of them and store it in
some central model class, then just loop through them and call
removePopUp()?

When an Alert is created with show(), it uses the PARENT space, thus all of
your popups will be above standard alert popups.
