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

But someone subclassing your Class may not have the same

developers to try to set properties on child objects in
commitProperties. I've even been advised to do so in this forum by
people I respect. Maybe in retrospect it was a bad idea to take such

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.

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

I am wondering if what I am experiencing with createChildren() is similar
to what you've
described below. I am subclassing UIComponent - and I read that it is best
to create
children in a createChildren() method.
However, I am tying into someone else's existing code and she has done some
nice work
with loading state. Her code creates a new instance (of the class mentioned
above that
extends UIComponent - let's call it BTProcess).
What I am finding is that after the instantiation, the new object is having
properties set ON
children that have not yet been instantiated and hooked up to BTProcess.
I am guessing that I could have the state-loading code broken into two
parts: one the
instantiates and one that listens for CREATION_COMPLETE event before
setting properties.
But I am wondering if there is a faster way to do this.
So, my question is does your approach address this by creating children in
commitProperties() and does this provide a work-around to the problem that
I am

Hi Manu,
This is a pretty simple answer. The reason is the mxml properties get
looped

descriptors.
This is why we need the invalidation system. You need the following.
public function set data(value:ArrayCollection) {
_data = value;
dataChanged = true;
invalidateProperties();
}
... in the same class
override protected function commitProperties()
{
super.commitProperties()
if (dataChanged)
{
// do things with child components IE
myGrid.data = _data;
dataChanged = false
}
}
Setting your child properties in commitProperties() guarantees your
children
will be created.

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

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

Hm, actually i don't quite get the problem, i think. States should be used in my opinion to really abstract view-states. The state of the application should be stored in a domain model. Yes, you're right. If u have buttons - just register listeners for the interaction and let a controller decide what to to depending on the view state. Yes, absolutely. As i understand your problem it's like you have different states, which not only refer to view states but als to states in terms of functionality which is bound directly to a statewhich i think leads to too much logic in view components... You are mostly there, but it's not to do with the view components themselves - it's about preserving context between state changes - I'm not suggesting that's a function of the view, it's a controller issue. Or i just didn't get your intention right... Mostly right. Thanks for posting. Paul Best regards --- In flexcoders@yahoogroups.com flexcoders%40yahoogroups.com, Paul Andrews [EMAIL PROTECTED] wrote: I think I know the answer to this, but here goes.. Lets suppose I have an application with states A, B and C, plus the default. There are buttons in states A, B and default to switch the application to state C. That would be all fine and dandy, but once I have entered state C, I can press a button to leave state C and return to the state from whence it was called (A, B or default). Still, no problem with that, but I'd like to keep the context of the previous state so that when I return to state A (for example) from state C, I can present the same view as before. Similarly, it may be that state B is really a substate of A (state Ab, if you like), so returning to the status quo might be a bit more difficullt. Really speaking I just need a state/state context stack that I push and pop as I move from one state to the next and back. Anyone already done similar with a different approach? I know I could get away without the stack if I implemented variants of state C that took into account the 'calling' state, but it quickly becomes a nightmare. This is certainly doable, I'm just seeing if there's a tried and tested way of managing state contexts like this.

Re: [flexcoders] dividerSkin problem
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.

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

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

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] Creating custom components in flex using actionscript 3.0
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?

forum, but could not resolve my issue.
My class extends a VBox and I try to create components in it. To
simplify and debug the issue, got down to only creating a simple hbox
inside the class and adding a button to it. So the steps are
1. create a class which extends vbox.
2. override createChildren method and set the height, width, and other
styles of the vbox and then call super.createChildren()
3. create a new HBox inside the createChildren method and then add a
button to it.I am setting the verticalScrollPolicy and
horizontalScrollPolicy to off, inside the createChildren method before
calling addchild.
On doing this I always see the horizontal scrollbar enabled. How do we
debug such an issue. i traced through the code and found that the
width and the height of the hbox is much lesser than the height and
width of the vbox. Is there any reason why this should be happening.
I also implemented the commitProperties method and I tried setting the
properties for the hbox in there but that did not help either.

You never assign an instance to a Class variable type. You need to create

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

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

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

Hold on a minute. Canvas uses absolute positioning. So padding

This seems kind of confusing. I'm with Tim, and think this would be better
solved with constraints. I suppose you could declare Spacers of
height=100% and whatever width you wanted, and position them with
constraints.

Another alternative, if you have to use a Canvas and don't want to

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

Something like this perhaps..
I'm assuming that the reason for the margin is to leave a gap
around the
edges. Lets say you want a 5 pixel gap.
mx:Canvas id=outerCanvas
mx:Canvas id=innerCanvas width={outerCanvas-10}
Oops.. mx:Canvas id=innerCanvas width={outerCanvas.width-10}
height={outerCanvas-10} x=5 y=5
height={outerCanvas.height-10} x=5 y=5
add other stuff here
/mx:Canvas
/mx:Canvas
Any good?
Maybe I've got the wrong idea about why you want the margin.

Re: [flexcoders] Re: Extending UIComponent memory issues.
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] Re: Efficiency and objects in the display list
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: Flex themes
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.

Displaying full html in Flex (Flash Player) is not yet possible. What are your requirements? The simplest solution is to use a separate browser to display the html help pages. The Flex side needs to know where in the app the user is, and be able to determine the url to display. Using ExternalInterface you can exercise quite a bit of control over that window's behavior. Doing it all in Flex will be more difficult, primarily on the editing side. Dynamic display based on xml content is easy, but building a dynamic layout that looks like a help system might be a bit tricky.

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.

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

The reason is you can stack interfaces on top of each other allowing more

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

Re: [flexcoders] Interfaces WHY?
But in general I think implementation inheritance is over-used and
multiple inheritance can get you into trouble.
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.

There's something odd about this class, because usually when you
start typing override protected function in a class, it has a whole
list of functions you might be overriding. But in this class, that
doesn't happen.
If anyone has any ideas, I'd be very grateful.

Re: [flexcoders] Re: Error 1150 when overriding protected function
Hi,
You Do have a mismatch brace
package com.magnoliamultimedia.views
{
import flash.display.DisplayObject;
import mx.charts.LegendItem;
import mx.core.UITextField;
public class WrappingLegendItem extends LegendItem
{
public function WrappingLegendItem()

}
} --- WRONG !!! :)
override protected function createChildren():void{
}
}
Right where the wrong is.
Should be...
package com.magnoliamultimedia.views
{
import flash.display.DisplayObject;
import mx.charts.LegendItem;
import mx.core.UITextField;
public class WrappingLegendItem extends LegendItem
{
public function WrappingLegendItem()

Re: [flexcoders] How to make a Docking Window Framework/component like Eclipse/InfoDock/JDocking
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] Dimensions of a UIComponent are allways 0, 0?!
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] Module vs Application
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] The Tree component sux but .... I need help :)
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.

question regardless of the title). The archives get searched all the time
and titles that are ambiguous serve no purpose. I read the question to, just

First of all, you should be talking about an application (not an swf).
Now, the SIX pages, I took it as SIX views.
There are many ways to do that. One of them is:
mx:Application
mx:Script
private function return nextPrevView():void{
if(buttonClicked == prev){
viewstack.selectedIndex =
viewstack.selectedIndex(viewstack.selectedIndex-1);
}
if(buttonClicked == next){
viewstack.selectedIndex =
viewstack.selectedIndex(viewstack.selectedIndex+1);
}
}
/mx:Script
mx:ViewStack
view1/view1
view2/view2
view3/view3
view4/view4
view5/view5
view6/view6
/ViewStack
buttonPrev/buttonNext/
/Application
It's just an outlook of an application.
Get it worked by urself.

Re: [flexcoders] Re: Getting multiple addedToStage events
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.

Of cause. This makes perfect sense. We don't want to reference the class.

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

I'll do the custom renderer on my 2nd pass of finishing up this
application. With this experience I've also found that using binded x/y
values 'y={something.x + something.y}' really really slows things down as
well. Changing that code I was able to get down to around 1000ms. Not what I
wanted, but more acceptable forsure!!
I can see where renderers would make the code much more managable, so it
will always be in the back of my mind as well.
I appreciate all the feedback and pointers...

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: Retry: Question for Doug McCune on Drag-drop component?
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.

On Wed, Sep 24, 2008 at 6:02 AM, Doug McCune [EMAIL PROTECTED] wrote: For basic dragging stuff, here's typically what I do. Have a mouse down listener on whatever component you want to drag. On mouse down you keep track of the coordinates where the user pressed. Then you add a mouse move listener to the system manager. Also add a mouse up listener to system manager. Then when the user moves the mouse (which you catch with the system manager listener), perform the calculation of how far from the original mouse down position the mouse is and move the component to the right place. Then when you catch the mouse up event (again, from system manager), you remove the mouse move listener and you're done. See the code in the Panel class in the Flex framework for an example of this type of dragging. The big thing to know is that you want to use mouse move and mouse up events from the system manager, not from the component itself. If you use the component itself you'll end up losing the mouse movement if the user drags quickly off the component, or you might get stuck in endless dragging if the mouse is released while not over the component. You should also probably have a listener for when the mouse leaves the stage and stop dragging at that point too, since not doing that can make the drag operation continue after the release the mouse (if they move the mouse off your app and the release).

Hi Jack,
Take a look at mx.skins.halo.TabSkin
This class is not like the ButtonSkin, you can see in this line exactly what

case upSkin:

var upFillColors:Array =

You will need to implement your own skin for that functionality.

However, it does not use the second set of values. I set the second

The Language Reference indicates you can use either one set or both
sets for fillColors in a TabBar.
The second set is for mouseover.
Does this not work in Flex 2.01?
I looked at the Flex 2.01 Explorer application and it only has 1 set
of colors to select from.
I even tried using a TabNavigator but it does not use the second set
of colors either.
In both cases, on mouse over, it displays a lighter color
combination of the first set of colors.
Does it work in Flex 3?
