that affects code.

The eLearning community, however, is waiting with bated breath for 
Flex example code that will allow people to get their heads around 
how, for instance, they can present pages of data driven content with 
a coherent navigational structure.  It's been almost a year since 
Authorware's EOD was announced, and people need something else they 
can do to with this type of content.  And if I retain the freedom to 
post generic code that doesn't reveal the specific business practices 
of the client, I'm in a better position to help people move forward.

The ideal would be for Adobe to step forward and provide some example 
code or assist community leaders in doing so, but so far we've gotten 
loads of lip service from various parties but no actual help.  So the 
ownership of the code isn't so much an issue for me personally, but 
more for the eLearning community that would like to use this tool but 
so far has been stymied by lack of a clearly documented path on how 
to do so.

Actually, the question was about signing a work for hire agreement 
and what other options there might be.  It looks like the client is 
open to negotiation on this issue.  After all, the client has already 
benefitted from code that I've shared with the community.  

Interestingly, the code I shared was created specifically for the 
presentation they attended.  The client I have done most of my Flex 
work for doesn't really care about sharing snippits so long as I 
don't hand over his whole system. But the code I did for him was too 
detailed and specific for the top level view I was giving in 70 
minutes.

It may be that I never share, for instance, the exact VO that I use 
for driving a multiple choice question.  But I'd like to know that if 
I want to base example code on stuff I do for this client that I 
don't put myself in legal jeopardy.

My fear is that if I were to sign the agreement as is even if I write 
tutorials from scratch the techniques might be inspired by things I

[flexcoders] Extra pixels on right side of TileList.

[Amy]

Hi, all;

I have the following MXML code













For some reason, the TileList has about 5 pixels on the right hand 
side of the last column of item renderers.  I've uploaded a picture 
of the result here 
http://www.magnoliamultimedia.com/flexissue/TileListCapture.jpg.

Note that I gave everything a garish color so it was clear what 
container was where.  If anyone has any ideas of how to get rid of 
those pixels, I'd be grateful.

TIA;

Amy

I'm letting Flex handle that, just as I would if I were working in HTML 
and using a table.  It's sizing the TileList, and my expectation was 
that it would size it snugly around the content.

> You might need paddingRight=0 on VBox or HBox?

I tried that already.  The padding is inside the TileList.  The 
TileList is the only thing that is that purple color.  If I add padding 
to the vbox, you can see that there are empty pixels to the right of 
the TileList AND the TabBar.

I added a click handler on the TileList as a shortcut to this.  The 
target is the ListBaseContentHolder with the parent id = "calendarDays".

The columncount is 7.  Would tweaking the size of the itemrenderer help?

Have you tried setting includeInLayout to false on the TileList until

I couldn't find a horizontalGap property on TileList, and trying to

compiler error.

Could you tell me a bit more about monkey patching?  Where does the

paddingLeft and paddingRight are ignored.  I tried setting them to some 
really high number just to see, and nothing happened.

When I take off the 100%, it is a lot smaller on the left hand side of 
the screen (not using the full width of the tabBar).  But one of the 
reasons I like Flex is because it has the capability of liquid layouts 
similar to HTML.  I guess I should be thankful that Flex automatically 
got that close, even though the native size of the itemRenderer is 
smaller...

How do most people handle this sort of problem?

I managed to managed to get an acceptable look by setting the TileList

I would think if you don't specify the dataProvider or itemRenderer 
of the TileList until you're ready to use the TileList, it shouldn't 
be that expensive to create.

You may want to try some combination of the following:

1) Do the setting in the setter tather than the getter
2) Type itemLocation as ArrayCollection rather than Object
3) Use BindingUtils to set up a binding as shown in this example

Why complain about the netiquette of others if you're not actually

trimming netiquette, some users don't care about using ridiculous

[flexcoders] Oversized label

If you use a repeater, this will happen automatically:




will give you an array of TextBoxes that you can access with

MyTextBox[0] - MyTextbox[n], where n is the number of items in your 
data source.

You can also do this manually

var MyTextBox:Array;

for (i=0;i<=numLoops;i++){
   MyTextBox.push(new TextBox());
}

You'd refer to them the same as above.

One thing that can help in this kind of situation is not to bind, but

My experience is that whenever the ArrayCollection's source changes, 
the repeater will update, but there doesn't seem to be so much of a 
cascading ripple effect--when you bind it seems to me like it 
refreshes way more times.  So if you don't bind, the refresh might 
not be as visible.

Even though it is tempting to use Application instead of 
WindowedApplication because of the lack of documentation on how to 
make WindowedApplication chromeless 
(http://flexdiary.blogspot.com/2007/07/application-vs-

[flexcoders] ViewStack sizing problem

[Amy]

I have a ViewStack that contains a TileList and some other components 
that have a variable number of children and thus a variable height.  
It seems that the ViewStack decides how big it will be before all the 
children are finished sizing.

I've tried adding logic in my override to commitProperties, 
updateDisplayList, and measure that set the height of the ViewStack 
directly based on the height (and I've also tried measuredHeight) of 
the VBox I have in the first child of the ViewStack.  I've also tried 
setting a bindable variable in these places that sets the height and 
binding to that.

My results are this:

commitProperties--never gets to the full height
updateDisplayList--stalls out (infinite loop?)
measure--stalls out (infinite loop?) with bound variable, never 
reaches full height with setting the property directly

Is there any way to use a ViewStack to simply change out the view 
without _having_ any height?  Alternatively, is there a way to 
persuade it to wait until the children are sized to decide how big it 
is or to look at the size again when the children are done sizing?

Thanks;

Amy

[flexcoders] uint unset value

[Amy]

I am working on styling a component, and I need to react to something 
where a color isn't set or is set to null.  I get a compiler error when 
I check for

if (!(_myColor==null)){
  //do something
}else{
  //do another thing
}

I can't be the first person to need to do this, but I don't see 
anything in the docs about it.

[flexcoders] Styling AdvancedDataGridItemRenderer

[Amy]

I'm trying to extend AdvancedDataGridItemRenderer to allow the 
styleFunction to set both the backgroundColor and the alpha of the 
item in.  I've used a combination of the custom style example in the 
docs and the example here http://flexpearls.blogspot.com/2008/02/row-
background-color-in.html.  The problem I'm having is that it doesn't 
matter what you set the alpha property to, it doesn't affect the 
visual appearance of the component.

I tried using the graphics object to draw the box, but it seems like 
the base component doesn't support this.  If anyone has any ideas, 
please share.

Does anyone else have the problem where if you want to do anything 
whatsoever in Flex you wind up having to roll your own version, and 
then none of the pieces work exactly the way they're documented?  
Some days I feel like even the simplest task is amazingly hard in 
Flex.

I actually wound up just comparing straight to the getStyle() result 
and comparing that to undefined, since that's what it is when it 
isn't set.  I haven't been able to find any examples that show 
different ways of dealing with keywords, etc., so I figured that was 
the safest way.

So when I see examples that show using uint for color data, that's 
wrong if I need to distinguish between black and not set, because uint 
isn't capable of making that distinction.  Correct?

I'm going through the UITextField code, looking to see why the f* 
AdvancedDataGridItemRenderer is so hard to style in the normal ways, 
and it looks like in that, they check it against 
StyleManager.NOT_A_COLOR, but use the uint type.  I'm not sure how 
they account for keywords, but presumably StyleManager works it 
out...?

OK, I think if I could somehow add a sprite to the component, I could 
make this work, but instead of addChild, it has AddChild, which shows 
three arguments in code hinting but throws a compiler error if I give 
it more than one.  If I give it a sprite as the one argument, it 
gives me a runtime error.

I can't look to see where it is drawing the background in, because 
that's in one of the Flash classes.  It doesn't look like those are 
included in the source that comes with FB3.

Anyone?  Anyone?  Buehler?

OK, I've tried the following code, but despite the fact that the 
alphaMultiplier is set properly, the background transparency isn't 
changing.  That's probably a good thing, since it would probably make 
the text semitransparent as well, but I am not sure how to get hold 
of just the background.

My styleFunction is just setting the background color for now, so 
getStyle is returning the default .5

I suppose I should feel flattered that I've asked a question that is 
so hard that no one here can answer it.  Let me try again...maybe 
someone knows the answer to just this piece of it and if I know that 
I can perhaps find a fix:  Why is it that setting the alpha property 
on the component does not modify the visual appearance of this class?

I've really tried to figure this out myself, but the inheritance 
trail disappears into the Flash classes, and I haven't been able to 
find the source of those.

Thanks!

If I were in your place, I'd make a temporary event handler for 
repeatStart, then put a breakpoint there and step through the code,

Which I did.  Just to back up a bit, the goal was to allow the 
styleFunction to set the color and the amount that you could see the 
rollover or selection indicator when the row was colored.  

But nothing I tried actually affected the alpha, until finally I 
changed the blendMode, which allowed the change to be visible, but 
both the text and the background, which wasn't the effect I was 
looking for, especially since it didn't match the 
AdvancedDataGridGroupItemRenderer, which descends from UIComponent 
and behaves sensibly.

It actually does, which is why it has an alpha property.  The secret 
is that you either have to embed the font or change the blend mode, 
otherwise it stubbornly refuses to show any changes you make to the 
property.

The problem is that I don't properly understand how it draws the leaf 
icon, so I am reluctant to mess with it too much.  My explorations in 
the source code didn't leave me any the wiser about this.

Ultimately, I abandoned my attempts to gain control over the alpha of 
the background and opted for something that allowed me to see the 
rollover in a reasonably attractive manner--setting blendMode on both 
itemRenderer classes to DARKEN.  I may have to change the mode on 
that once I get the real styleFunction working rather than just a 
placeholder that returns back yellow to everything.  I'll probably 
just add a style that sets the blendMode, so I can adjust it based on 
the color needed.

I wish the docs would point out these limitations so that people can 
estimate time needed to accomplish tasks better.  If you read the 
docs, it sounds like this task should be a walk in the park.

I didn't know that I could use my patched 
AdvancedDataGridGroupItemRenderer as the regular itemRenderer as well 
and have it just work.  I assumed that there are two distinctly and 
yes irritatingly different classes for a reason.

It turns out I am having a problem dynamically setting the icon on 
leaf nodes... when I use an iconFunction, the function returns the 
right thing but it is never drawn (even with changing out the 
itemRenderer).  When I use a groupIconFunction, it only runs for the 
items that are parents.

That's sort of similar to what I have, I just wasn't using it for the

It worked fine for me.  Here's a snippet:
if (_StylePropChanged) 
{
_backgroundColor=getStyle('backgroundColor')
if (_backgroundColor!=StyleManager.NOT_A_COLOR){
this.background=true;

this.backgroundColor=_backgroundColor;

this.blendMode=BlendMode.DARKEN
}else{
this.background=false;
this.blendMode=BlendMode.NORMAL;
}
_StylePropChanged=false;
}

That, at least, was solved relatively painlessly.  Before I realized 
there were two different classes handling the rendering, I forced the 
first column to my patched regular ADGItemRenderer (because that put 
the color in more rows in that column).  So the only time it used my 
GroupItemRenderer was when it actually was displaying a group, which 
seems to override the hardcoded itemRenderer.

information on how the child items should be viewed.  So the same child 
might be in the tree three different types under different parents.  I 
left the view information in the container, since it has nothing to do 
with the actual data contained in the child object.

The problem I am having is that I don't seem to be able to find a way 
to get at that data from the parent data when a user clicks on a child.

Thanks :-)

It's not best practice, but you absolutely can pass references to 
things outside an object's scope into the object.  I did this with a 
component I wanted to "reparent," i.e. I had a series of components 
duplicated in a Repeater, and when you clicked on one of them, it 
would grab the component I'd passed a reference to and add it to 
itself.  I was doing this to make something that looked like an 
Accordion but could take a dataprovider and recycle the same object 
rather than having multiple copies.

Essentially, you just put a property on the component with type 
UIComponent and push it in through the ClassFactory if it is an 
itemRenderer or you can set it directly if it is not.

If you set up an interface that the component you are referring to 
has to adhere to, you can actually do this without requiring tight 
coupling.  I didn't need to worry about that, because the only thing 
I did was addChild().  However, you may want to consider just having 
the components bound to the same data and have the data push the 
changes.

OK, I got the bright idea that I would composite the existing class 
with a new class that has a uid.  The class looks like this:

package com.magnoliamultimedia.vo
{
import mx.core.IUID;
import mx.utils.UIDUtil;

public class TaskUID implements IUID
{
private var _task:Task;
private var _uid:String;

public function TaskUID(task:Task)
{
_task=task;
_uid:UIDUtil.createUID();
}

public function get uid():String
{
return _uid;
}

public function set uid(value:String):void
{
throw new Error("Can't directly set UID");
}
public function get task():Task{
return _task;
}
}
}

The problem is that as soon as the ADG loads, I get a ton of "Can't 
directly set UID" errors.  I thought Flex was _not supposed_ to set 
UID's on classes that implement IUID?  Note that this is not a visual 
clas, these are typed objects in an ArrayCollection of typed objects 
that have ArrayCollections in them named children 
(HierarchicalCollection).

If Flex is adding a UID to my objects, is there any way I can tease it 
out to use it to determine the parent?

Not sure about what happens in other OS's, but in the vast majority of 
Windows Applications, it is _very_ standard behavior for the button 
that is in focus to activate when the user presses the  key.  
The exception is for checkboxes and radio buttons.

I found that my code wasn't adding the UID where I thought it was.  
When the HierarchicalCollection called the UIDUtil class, the UIDUtil 
class saw that my component was an IUID but had a null UID and set a 
UID on it.

This suggests that it should have also been adding a mx_internal_uid 
to my old class that did not implement IUID, but I could never get at 
it.  In retrospect, I'm not really sure how much good it would have 
done for it to do that, since it was always the _same_ instance that 
it would have been added to.  Somewhere in the asdoc comments of one 
of the classes I stepped through to find this was a comment to the 
effect that two references to the identical object shouldn't have 
worked in the first place.

So, in summary, I think that the HierarchicalCollection _can't_ 
handle this situation, because to do so it would have to make the 
same instance different, which is why I needed to do something to 
wrap the same instance in different instances of another class.

Live and learn.  At this rate my head will explode by mid July.

Hi, Patrick;

You don't say what your component is, but I'm going to assume it's an 
extended button.  If you extend instead from a component that 
supports 
borderSides as a style (any container), you could try something like 
this:


.topLeft{
borderColor:#00;
borderSides: 'top left';
}
.topRight{
borderColor:#00;
borderSides: 'top right';
}
.bottomLeft{
borderColor:#00;
borderSides: 'bottom left';
}
.bottomRight{
borderColor:#00;
borderSides: 'bottom right';
}


Then, in your script block:

for (var i:Number = 0; i

The graphics object.  Essentially, that would remove the whole row

You can cast HierarchicalData to HierarchicalCollectionView for the

I know this isn't going to be popular advice, but my experience is 
that the List Base controls do a lot of stuff under the covers that 
is only documented in about 4 peoples' heads.  Unless you're dealing 
with huge data sets, you may find that switching to a repeater saves 
you a lot of headaches.  I have a rule that if I ask on here for 3 
days with no solution, I switch to a repeater, since I am typically 
not working with large data sets.

I think that some of the extra calls you're getting to your function 
are the "invisible" controls that get built for scrolling purposes.

[flexcoders] AdvancedDataGrid rowCount

Hi, all;

I open all the nodes on my ADG when it is created.  I'd like to make 
sure there are enough rows to show all the items without scroll bars.  
If I bind rowCount to myADG.dataProvider.length, it gives me enough 
rows to show the _closed_ nodes.  I also tried 
myADG.dataProvideropenNodes().length, but that wasn't anywhere close.  
Is there a simple way to do this, or do I have to write a function that 
goes through and counts?

Let's assume your dataProvider is an ArrayCollection, and you're using

It seems that the length DOES reflect the total number of nodes, but 
for some reason I was not able to bind directly to the length of the 
dataprovider.  When I used a separate variable set to the length, it 
worked perfectly.

Did you ever get this solved?  I had a similar problem today and it 
turns out I had a filter on the errors because of some third-party code

On the problems pane there's a button that looks like a yellow arrow 
with a smaller blue one above and below it.  If you click that, you can 
set filters on the compiler errors that FB will show you.  Nice when 
you get someone else's code that generates (hopefully harmless) errors, 
but it can make it harder to remove those errors in your own.

I make a habit of looking at the bar down the right side of the FB3 
window for yellow blobs that will at least alert me to errors in the

I've used code like this in the past

while (myParent.className!='ComboBox'){
  //pretty much everything will have either a parent or an owner
  if (!(myParent.owner==null)){
  myParent=myParent.owner;
  }else{
 myParent=myParent.parent;

}

//myParent is a ComboBox if you get to this point

Note that you need to be REALLY sure this will eventually hit a 
ComboBox, or it will result in an endless loop.  You can add in a 
loop counter for safety, and exit after, say, 100 loops in case of a 
failure to find a combobox.

Possibly you could also extend ComboBox to listen to SystemManager 
and redispatch events.

Hi, Jason;

Not sure if this relates to your error, but I think you have to 
override the clone() method for custom events.

Yes, but with the built in help I can limit my search results to zoom 
in on what I am looking for.  The LiveDocs search searches the world.  
A lot of the time I go through the built-in help to get to the LiveDocs 
page I am looking for if I want to post a link to something, because it 
is MUCH faster even counting the time it takes to launch FB3.

Thanks, though.

What are you trying to accomplish?  If you're debugging, you can look

Google is able to get to the content of a swf and spider it?  Neat, but 
at the same time a little scary...

I don't think limiting it to adobe.com is very helpful, since depending 
on what you're asking, you could get FB 1.5, Flash, or even something 
completely unrelated.  My filters in the built in help are VERY 
specific, and I can put my fingers on what I need in seconds.

While I saw Randy's posts on how to limit the search using the google 
site keywords to get it just down to the LiveDocs for the version of 
Flex you're interested in, to me that's a bigger PIA than just going 
through the help.  And of course, it doesn't provide the specificity of 
the search context in the help.  My main concern about going through 
the help is that FB3 running with the help open will use more and more 
memory until my laptop is burning my legs.  If it weren't for that I'd 
have Flex open all the time and it wouldn't matter.

Couldn't he also do something like this in the component:

private var _obj:Object;
private var _objChanged:Boolean;

public function set obj(obj:Object):void{
  _obj=obj;
  _objChanged=true;
  invalidateProperties;
}

public function get obj():Object{
   return _obj;
}

override protected function commitProperties():void{
   super.commitPropertis();
   theButton.label = obj.str;
}

I personally would also pass in the property name to bind to to make 
it loosely coupled, but that's JMO.

I think your problem is that when ou are calling lblClientName, etc., 
those objects haven't been instantiated yet.  What event or function is 
calling your init() function?  Make sure it is not being called prior 
to commitProperties().

The problem with having only one onComplete event is that there is 
not just one thing that can happen.  There is a result event for when 
the service returns successfully and a fault event for when it fails.

If you implement IDropInListRenderer, you can get access to the 
DataGridListData properties.  Also, AdvancedDataGrid supports a style 
function, that you can use from outside the ADG to set styles.  For 
more on that http://flexdiary.blogspot.com/2008/06/musings-on-
advanceddatagrid-part-1.html

I actually didn't provide any examples, just talked about the general 
principles, unless you're talking about the posts that I linked to 
that didn't quite do what I wanted.

The styleFunction will do whatever you tell it to, so you can very 
easily use that to style the columns based on the dataField that is a 
property of the object you get in the second parameter.

So you could use something like this:

private function styleMyRenderers(data:Object, 
col:AdvancedDataGridColumn){
if (data[col.dataField]=='foo'){
return {backgroundColor:0xFF};//red
}
return {backgroundColor:0x00FF00};//green
}

No, but I wound up subclassing from AdvancedDatagridGroupItemRenderer 
because the AdvancedDataGridItemRenderer couldn't be made to support 
alpha in the background but not the text.  I suspect anyone wanting 
aplha transparency might have the same problem with the renderers on 
your site.

Why not just do whatever you need to do in the itemClick event for the 
ADG?  This fires no matter what kind of node it is.

Have you tried just using an iconFunction?

The AdvancedDataGridGroupItemRenderer doesn't have a renderer property, 
so could you be more specific about what you're doing?

What are the scenarios that result in the problem?

What happens if you create a style object and use headerStyleName?
