Re: [flexcoders] custom components destroy Flex design mode ....
I've run into similar situations before with 3rd party components. For some reason, some of them just utterly break the MXML design mode. I've also done it myself when subclassing the charting components. You just get a big rectangle with a big red X over the whole area.

Just grabbed the SteelPotato footerdatagrid to see if it can be seen if it is used. Nope - stops design mode. Wanted to try it because our implementation of Alex's solution also stops design mode from opening. The FlexLib buttons do the same thing - code them into source view and no more design view. How do you deal with this? Our corporate dashboards are starting to get very detailed and we need a WYSIWYG view to adjust things. Do we really have to compile, run application, view in browser, check, and then go back to source mode to increase the width of a button if needed? Any info really appreciated.

[flexcoders] charting and/or grid replacements
Are there any 3rd-party charting and/or grid replacements in progress that anyone wants to talk about? I'm looking to move away from the AdvancedDataGrid and possibly also Flex charting and am wondering what might be on the horizon. Right now Adobe pretty much has the only game in town for these Flex components as far as I know. I really wish DevExpress could be brought around to developing for Flex. Their grid components can have a incredibly steep learning curve due to the staggering amount of features, but I've found them to be quite a perfect fit with a professional quality application. I can only imagine what they'd build from scratch for Flex. This is not to dump on Adobe, necessarily. They're trying to organize their budget where they thing it's most effective, even if I disagree with it. But without a rich 3rd-party component ecosystem, I'm afraid that this great technology (I'm totally in love with the general process of programming for Flex) might wither on the vine. -- Jason

Re: [flexcoders] Re: how can you make the icon in an AdvancedDataGridGroupItemRenderer accept clicks?
Yes, I wondered why they set it, too. It's quite mysterious.
And as far as extending ADGGIR - have you looked at that code? They were
good about making very little of it private or mx_internal (yes, I know I
can get around the latter), but the bulk of it is done in commitProperties.
So you'd be limited to just stuff you could take on to the end of the
overridden function. Likely I'd just clone the unit and change the bit of
code I was interested in.

I'm glad you found an easy way to get the functionality you wanted.
According to the docs, mouseEnabled defaults to true. I wonder why the
ADGGIR constructor sets it to false? Also, why don't the docs reflect this?
I just wanted to say that if you still wanted the functionality from
AdvancedDataGridGroupItemRenderer and you wanted extra functionality, you
can extend AdvancedDataGridGroupItemRenderer for your renderer. Best of both
worlds ;-)

AFAIK. you can't capture a mouse event on a Class object as it does not

lot nicer to add rows in my addCategory function. But I can't as long as
it's going to be so jittery.

Re: [flexcoders] Re: how can I get a popupButton's popUp to resize while popped up?
Thanks, Tim. Knew there must be something, just couldn't find it.
I found this to be a good way to do it, as long as I'm not missing
something:
gr.validateSize(true);
var verticalGap:Number = grid.getStyle(verticalGap);
grid.scrollRect = new Rectangle(0, 0, grid.width + gr.measuredWidth,
grid.height + gr.measuredHeight + (isNaN(verticalGap) ? 0 :
verticalGap));
This seems more right, though if you add some big numbers to height and
width it will always auto-calc them. But I found if you add numbers that
are too small, you wind up with it chopped off a bit.

C'mon, Tim, your posts help me loads of times and you don't even realize
it. My #1 place to go for searching for answers to tough problems is my
flexcoders archive and your name pops up a lot with the answer! And
RowColorDataGrid was a lifesaver.
Okay, back to the topic. Just realized that there's a little something
missing. If you have the popupButton on the bottom of the window so that it
causes the popup to appear ABOVE it, then the code above glitches in that it
makes the window grow down and cover the popupbutton. Here's a fix:
gr.validateSize(true);
var verticalGap:Number = grid.getStyle(verticalGap);
grid.scrollRect = new Rectangle(0, 0, grid.width + gr.measuredWidth,
grid.height + gr.measuredHeight + (isNaN(verticalGap) ? 0 :
verticalGap));
if (grid.y myPopupButton.y)
grid.y -= gr.measuredHeight + (isNaN(verticalGap) ? 0 : verticalGap);
To see this in action in the above example, set the application
layout=absolute and the myPopupButton bottom=0.
Of course, when you add so many categories that it gets taller than the
window its in, then you're screwed! You'd have to implement your own don't
grow when bigger than this and turn on scrollbars instead logic. Luckily I
don't need that right now.

Re: [flexcoders] Re: how can I get a popupButton's popUp to resize while popped up?
I should know better by now to never declare victory until you tried your
test app solution in your REAL app.
A problem occured that if your popupbutton is embedded in another control,
the y value will no longer be in the same frame of reference as the popup,
which is no a child of the same control as the popupbutton. So this may not
be the BEST way to do it, but it works:
gr.validateSize(true);
var verticalGap:Number = grid.getStyle(verticalGap);
grid.scrollRect = new Rectangle(0, 0, grid.width + gr.measuredWidth,
grid.height + gr.measuredHeight + (isNaN(verticalGap) ? 0 :
verticalGap));
if (grid.localToGlobal(new Point(0, 0)).y grid.owner.localToGlobal(new
Point(0, 0)).y)
grid.y -= gr.measuredHeight + (isNaN(verticalGap) ? 0 : verticalGap);

[flexcoders] getting files in additional Source Paths to automatically recompile
I have a couple of external folders listed in my project's Flex Build Path-Source Path section. These folders are outside of my project hierarchy and contain some common files I share between several different projects. When I'm in my project and ctrl-click on an object in these files, it opens the file properly. But if I make changes and hit save, it doesn't recompile my project to include those changes. If I make changes in the project and it rebuilds, it still doesn't get the changes in that external file. Only when I do a Project-Clean does it recompile those external files in. Is there some better way of setting it up so that it will be more intelligent about figuring out it needs to recompile those files on changes? -- Jason
Re: [flexcoders] Re: how to fix poor performance in this example (AdvancedDataGrid and Binding)
This seems like probably the best option. I suspected that it was something
to do with properties changing causing excessive refresh, but the fact that
Alex didn't point that out as the problem kind of threw me off track.
It appears that the highlight is set in drawItem, so I subclassed ADG and
overrode it, setting the highlight property. I added a bit to the highlight
to make sure the event only gets fired if the value actually changes.
As to your question of using selectedItem, the problem is twofold. First,
the problem is that the grid doesn't provide any property for
highlightedItem. Yes, as Tim said I could subclass and create one (much
like I did above). But the secondary problem is that I want several bits of
code that aren't interconnected to do something when a given item in the
data list is active. I don't want these different bits of the code to
have to know about controls and grids. I just want them to see a data
element changing and respond to it. Secondly, this is complicated by the
fact that I can lock some elements into the active state. So I might have
item 2, 4 and 8 locked on and be mousing over item 5. The other component
will show items 2, 4, 5 and 8 all active.
By the way, Tim, I had composed this as a response to your suggestions but
not go around to sending it to you yet:
Well, the problem with that and with your example is that they rely on the
itemRenderers to do the management of the highlighted variable. That was a
tangent I got on to show that it wasn't just the fact that it runs through
an ArrayCollection that was breaking it. The problem with the itemRenderers
managing it is that there is dead space between item renderers (i.e.
padding) that the renderers never see.
Thanks everyone for your input on the problem!

When you set the highlighted property on your items, they are
dispatching PropertyChangeEvents. The collection they are in will
receive these PropertyChangeEvents and dispatch CollectionChangeEvents.
The AdvancedDataGrid will receive these and perform a visual update,
which appears to clear the rollover highlight.
To prevent the rollover highlight clearing you need to avoid dispatching
PropertyChangeEvents when you update the hightlighted property. Which
means you need to use a custom event in your binding (see below). This
should fix the choppiness without breaking the binding, although you
might want to rethink this whole approach: When you select an item in a
datagrid it sets the selectedItem property; it doesn't update the
underlying data items. Why not follow this pattern for tracking which
item is rolled over?

}
[Bindable( event = highlightedChange )]
public function set highlighted( highlighted : Boolean ) : void

_highlighted = highlighted;

}

Yes, a mushroom indeed - well put! By the way, I found your posts about your fun with the various ADG item renderers quite informative. Though you did leave me wishing for some source code of the working examples. The problem here is that this data serves to link up different parts of the UI. It's so that many different pieces can look in one place and hook to one set of variables. It also serves as abstraction. I have a chart that I can instantiate any number of copies of (with different views of the data, etc.) I don't want this chart to have to have knowledge of this one fixed grid. The grid is also reused in a couple of different ways, so i don't want the grid to be hardcoded to the chart. It's the perils of abstraction and modularization.

Re: [flexcoders] Re: how to fix poor performance in this example (AdvancedDataGrid and Binding)
I think you missed the part above where I said more than one item could be activated. Some items can be locked on, and it also includes the currently selectedItem (which can be different than the one being moused over). The examples were dumbed down so people could easily figure out where I was seeing the problem.

I have a chart that I can instantiate any number of copies of (with different views of the data, etc.) I don't want this chart to have to have knowledge of this one fixed grid. The grid is also reused in a couple of different ways, so i don't want the grid to be hardcoded to the chart. It's the perils of abstraction and modularization. If you had one variable containing _just_ the highlighed item at the controller level, that would actually be even more abstracted and reusable than tying everything to the entire collection and forcing things to look at a property on one item of the collection. Also more efficient. -- Jason
[flexcoders] how can you make the icon in an AdvancedDataGridGroupItemRenderer accept clicks?
I've got a bit of a problem and haven't been able to figure it out. When
using hierarchical views with ADG, I find that the icon can't be clicked on
to select the row. I can't figure out how to capture a click on the icon at
all.
?xml version=1.0 encoding=utf-8?
Application
xmlns=http://www.adobe.com/2006/mxml;
Script
![CDATA[
// put any icon you want in the embed below, doesn't matter
[Bindable] [Embed(source=imageA.png)] private var imgClass:Class;
private function geticon(item:Object):Class
{
return imgClass;
}
]]
/Script
AdvancedDataGrid iconFunction=geticon itemClick=trace('itemclick')
click=trace('gridclick')
dataProvider
HierarchicalData childrenField=subitems source={[{label:'test'},
{label:'test2'}]}/
/dataProvider
columns
AdvancedDataGridColumn dataField=label/
/columns
/AdvancedDataGrid
/Application
If you click anywhere but the icon, the gridclick and itemclick events both
fire. But if you click on the icon, you get only the gridclick. And the
gridclick event doesn't get anything useful for target/currentTarget, as far
as I can tell.
The main thing I really want to do is have clicking on the icon select the
row, just like clicking anywhere else will do. Tangentially, it would be
nice to know how to capture the event in case I wanted to do something
different with clicking on the icon.

Re: [flexcoders] Re: how to fix poor performance in this example (AdvancedDataGrid and Binding)
1) Yes, this works fine, for the display portion only. It doesn't address the actual problem of needing to set a flag in the data that indicates it is the currently highlighted one, that flag being also used by other things that bind to the data that don't want to know about UI details like the grid. In this case, I had a number of chart listeners that would toggle series on/off depending on which one was highlighted in the grid. 2) There is no commitProperties on AdvancedDataGridItemRenderer. Perhaps you meant validateProperties. In this example, it gets called only when the grid is first displayed and not when any item is highlighted/de-highlighted or selected/de-selected. 3) Yes, the styleFunction does get called when the highlighted object changes. But if you move the code to set data.highlighted there, you get the same result! It just seems like anything that changes this bound variable on every repaint of the cell is doomed to break the rollover highlight.

In this example, I don't loop through the dataprovider but instead only
affect the itemRenderer being redrawn. Yet if you try this example with
highlighted being a [Bindable] variable, it breaks, not just failing to show
the highlighted item in bold but also breaking the grid's blue highlight.
Comment out the [Bindable] part in TestObject, and it works just fine.
I'm hoping Alex is still following along.
I'm trying to get my itemRenderers in a big complicated grid as lean as
possible, as per Alex's suggestions on his blog. The highlighted data is
also being used in a couple of different places that are abstracted a bit,
otherwise I'd hardcode something a bit more kludgy.

Re: [flexcoders] Re: how to fix poor performance in this example (AdvancedDataGrid and Binding)
Oh yeah, another thing I should point out is that in the real grid, I have
multiple columns. As such, a solution that relies on the itemRenderer might
be problematic due to gaps between items and such. I would just use the
itemRollOver and itemRollOut to do it all, but rollOut doesn't get reliably
called for every highlighted row when the highlight leaves it.

I have the following example that is a very simplified form of what I
need to do in my much larger program. The goal is to have a mouseover on a
grid item set a variable in the data object. In the real program, this
fires off some other code which makes that item visible and the others
hidden, etc. But here, I'm just trying the first part.
*TestObject.as:*

To see the problem, run your mouse up and down the list on the left and the
list on the right. If you get the same results I do with SDK 3.0.2 and
player 10,0,12,36 (FF 3.0.6 or IE 7), you'll see that the list on the right
tracks very smoothly but the one on the left is choppy. The only difference
between the two is that the one on the left has a rollOver handler that sets
a Bindable variable in the data object.
If you comment out the [Bindable] on TestObject's highlighted variable, the
choppiness goes away. So it's something to do with all the binding glue
being fired behind the scenes. Is there some good way to work around this
while still being able to use binding in this way?

Re: [flexcoders] Re: using as breaks data binding?
I'm not sure I fully understand what you mean, Alex. In my button click

jotting in a comment on the but reports I entered to just confirm that you
were able to reproduce it in 4.0?
Does this mean as should be avoided and only used in cases where the
ClassName() syntax will wind up doing more than just type coercion (like
Array) for now?

respond to changes to some kinds of changes because it isn’t watching the

data object changes, but if you found a way to just modify the one property
it probably won’t pick that up.

I think I may have an answer. I broke down the code into its constituent
pieces and I now have a theory.
My theory:
When you use (data as TestObject).b, you are actually trying to bind to the
data property of the item renderer. As this is not a bindable property, you
get the error. When you use the cast: TestObject(data).a, you are now
binding to TestObject which does have bindable properties.
Have a look at the following code...
TestObject.as
package
{
public class TestObject
{
[Bindable] public var item1:uint = 2;
[Bindable] public var item2:uint = 3;
[Bindable] public var item3:uint = 1;

The reason it doesn't give a warning on y is due to what I referenced

bind
to that value on the *itemRenderer *(GenericTest_inlineComponent1 in my

It's got me beat.
Why would the posted code give an error at all?

There's a couple of things that stand out here. First, it doesn't complain
about properties x or a. The reason it doesn't complain about property
a is that I used TestObject(data).a instead of (data as
TestObject).a. If you change it to the other way around, you will get a
warning on a as well. I find this rather bizarre, as I thought there was
no functional difference to the two, other than as returning null if the
object wasn't of the appropriate type rather than just erroring out like
straight type coercion does. But type coercion/as are very (ahem) lightly
documented so I admit I don't know a lot. But I don't think it's because of
the null problem, since you can replace it with TestObject(null).b and it
stops giving the warning.
The second weird thing is that it doesn't complain about x when using
(data as TestObject).x like it does with a. As you can see, it's claiming
this error is on GenericTest_inlineComponent1. This is significant
because it appears that it's instead doing some binding to the x property
on the item renderer, which is *very* odd. You can try this yourself by
changing x to other strings. Ones where there is a property of HBox named
the same thing won't give you a warning. Others will.
Yet for all this griping, it seems the data binding IS working. If you
click on the button, you'll see all the labels in the list change as the
data is being changed.
So, anyone want to shed some light on these two behaviors?

Re: [flexcoders] Re: using as breaks data binding?
Thanks for giving me some confirmation. Now if we could just figure out
what Alex/Adobe need to do to replicate our tests.
The reason it doesn't give a warning on y is due to what I referenced
(perhaps unclearly) above. Notice in the warning it tells you it can't bind
to that value on the *itemRenderer *(GenericTest_inlineComponent1 in my
test), not on the *TestObject* instance. The itemRenderer has an x and y
object, so that's why it doesn't complain. It doesn't make any sense that
it should be looking at binding to the itemRenderer instead of the
TestObject instance, though.

As a sanity check I tried it and I get the exact same error. I am using
Flex SDK 3.3.0 and Flash Player WIN 9,0,159,0 Debug.
Strangely enough, changing b to y fixes it and the error goes away. Other
variable identifiers I have tried (Very small sample) gives the error as
well.
It's got me beat.
Why would the posted code give an error at all?
Why would y work and everything else not?

Well, I entered the two related issues as:

Maybe someone at Adobe can manage to reproduce them. I'm not really sure
how much harm is being done, since the code appears to work right in the
end. But someone weird and unexpected seems to be going on under the hood.

[flexcoders] where does AdvancedDataGridColumn.id come from?
This puzzles me a bit. There is no such property as id on AdvancedDataGridColumn or its ancestors. So why doesn't the compiler barf and give you an unknown property at compile time (it does at runtime)? Is this some kind of kludge in FB such that it always allows an element called id to be stuck on some components (like CSSStyleDeclaration descendants)? -- Jason
Re: [flexcoders] where does AdvancedDataGridColumn.id come from?
Well, there is an there isn't. UIComponent actually defines a property of called id. AdvancedDataGridColumn isn't a UIComponent, its a descendant of CSSStyleDeclaration, which does not define id, nor does its ancestors. So I guess I really knew the answer before I asked it in that it's a bit of a kludge to let you name objects in MXML so you can refer to them later. Then at runtime, this information just isn't there because it really never existed.

Re: [flexcoders] for better performance, use as rather than just leaving an object as Object?
Thanks for the input, Alex. True, it did take a lot of iterations to get a one second difference, but that's with only one reference to a property. If I had something like: o.foo.bar[3].baz = o.foo.getBaz(), I've suddenly quintupled the number of FindProperty calls. Ditto if I had a few lines of calls, all working off of o. But mainly I agree that you have to consider whether a given optimization is worth it if the code doesn't actually need optimizing and the optimization will make the code harder to understand and maintain. That's why this is such a good tip, since I wanted to use as anyway to make the code more maintainable! Good point about SWF/RAM size, though. You finally got me to bother setting up some RSS subscriptions in thunderbird. I always mean to read the various excellent Flex blogs, but never get around to it. Maybe this way I'll be more likely to get those useful nuggets of knowledge. I'm already looking forward to implementing some of your tips on itemRenderers (especially the image centering ones) to try to speed up a particularly painful ADG redraw. On Tue, May 5, 2009 at 12:24 AM, Alex Harui aha...@adobe.com wrote: I published similar results on my blog a few years back. The reason it is slower is that there are more byte codes involved and those byte codes take more time. The more you know, and the more information you have handy, the less work there is to do and we can make more assumptions. For “b.id”, the byte code is more or less: Push “id” Push “b” GetProperty For “(b as button).id”, the byte code is roughly: Push “id” Push b Push button Coerce GetProperty For “o.id”, the byte code is roughly: Push “id” Push “o” FindProperty and FindProperty is much slower. Note that it takes 1000 accesses to feel a 1 second difference. There’s more byte code involved in using “as” so if you did it everywhere your SWF will be larger and take up more memory at runtime and could offset those gains. However, if you’ve got the time, it might be worth doing from a code maintenance standpoint as the compiler will help you find misspellings and what not.

I was curious as to the difference between a few different ways of approaching the situation of an itemRenderer having a data property and deciding whether or not to use as to make all the type checking happy. So I tried some test code and found that it made a big difference whether you use as or just leave the data property as an Object. If you leave it as an Object, you get a performance hit on the order of 40%+ longer than if you use as to cast it first. Here are the ways I tested it. I just decided to pull the id property because it's something that is just a simple access of a private variable, no complicated stuff. var b:Button = new Button; var o:Object = b; var s:String; s = b.id; s = (o as Button).id; s = Button(o).id; s = UIComponent(o).id; s = (o as UIComponent).id; s = o.id; I did get a bit fancy and put them in a loop and a timer to isolate each one. The full code is included below. What I found was along the lines of this (give or take a few %): Button: 3.16 Button(): 4.06 129% as Button: 4.14 131% UIComponent(): 3.98 126% as UIComponent: 4.03 128% Object: 5.38 170% I put in the UIComponent ones because sometimes I cast it to a superclass because I might get several different subclasses passed into a function. So what I've found is that if you ignore than noise, the middle four methods are also approximately the same in timings. But the Object one is far worse. This probably won't come as any surprise to the Adobe folks or the people who have been working with Flex a bit more in-depth. I found it rather useful information, though, considering I'm trying to shave off some time in various places in one of my apps. Granted, it won't matter as much outside of loops. So many things return the items as objects, such as Arrays/ArrayCollection, the data property of item renderers, etc. I think I'm just going to make it a habit to put as in my code (and not the format of Class(variable) because sometimes that triggers a function rather than just doing a casting) all the time. It helps catch errors by doing strict type checking (as long as you aren't using dynamic classes) and it's a little faster to boot. Still, I wish it was as fast as the top line where you don't have to do any casting/as at all. Any thoughts on that or anything else I've missed? Any flash

UIComponent(): 3.98 126%
as UIComponent: 4.03 128%
Object: 5.38 170%
I put in the UIComponent ones because sometimes I cast it to a superclass
because I might get several different subclasses passed into a function.
So what I've found is that if you ignore than noise, the middle four methods
are also approximately the same in timings. But the Object one is far
worse. This probably won't come as any surprise to the Adobe folks or the
people who have been working with Flex a bit more in-depth. I found it
rather useful information, though, considering I'm trying to shave off some
time in various places in one of my apps. Granted, it won't matter as much
outside of loops.
So many things return the items as objects, such as Arrays/ArrayCollection,
the data property of item renderers, etc. I think I'm just going to make
it a habit to put as in my code (and not the format of Class(variable)
because sometimes that triggers a function rather than just doing a casting)
all the time. It helps catch errors by doing strict type checking (as long
as you aren't using dynamic classes) and it's a little faster to boot.
Still, I wish it was as fast as the top line where you don't have to do any
casting/as at all. Any thoughts on that or anything else I've missed? Any
flash insiders want to give your insight on why it works this way under the
hood?

[flexcoders] very strange combobox problem when switching dataproviders

}
]]
/mx:Script
mx:ComboBox id=c1/
mx:Button label=change click=change()/

What does it do? Well, the combobox changes from saying b to a. The
trace says the following:
before change:
c1.selectedIndex: 1
c1.selectedItem: b
after change:
c1.selectedIndex: 0
c1.selectedItem: b
This is completely baffling. My only guess is that somewhere in the guts of
combobox or its ancestors, it is registering for changes on a dataProvider
and not unregistering them when the dataProvider changes. List does not
seem to suffer the same problem.
If you comment out the ArrayCollection-based version and uncomment the
Array-based version, it works as expected.
My next stop is a bug report, but I figured it'd be worth bringing up in
case anyone already knows of a bug report (kind of hard criteria to search
for) or a workaround if you need to use ArrayCollections.

[flexcoders] What determines a component's initial skin?
I've been dinking with extending PopUpButton and have run into something that really puzzles me - how does it know to load PopUpButtonSkin by default? There is no code that mentions it in PopUpButton. Is it somehow selected based on the class name? In my PopUpButton descendant, I want it to load a different skin by default.

[flexcoders] Strange error about declaration of style conflicting with unrelated class
I'm receiving a very peculiar error. I've boiled it down to a simple
reproducible test. Given the following two files:
GenericTest.mxml:
?xml version=1.0 encoding=utf-8?
mx:Application xmlns:mx=http://www.adobe.com/2006/mxml; layout=absolute
mx:Script
![CDATA[
private var test:TestStyle;
]]
/mx:Script
/mx:Application
TestStyle.as:
package
{
import mx.core.UIComponent;
[Style(name=color, type=uint, format=Color, inherit=no)]
public class TestStyle extends UIComponent
{
}
}
I get the following error trying to compile, ever after cleaning the
project:
Severity and DescriptionPathResourceLocationCreation Time
Id
Declaration of style 'color' conflicts with previous declaration in
C:\Program Files\Adobe\Flex Builder
3\sdks\3.2.0\frameworks\libs\framework.swc(mx/core/Container).
GenericTestUnknown123152185967429620
First, I'm pretty sure the claim that it's Container causing the problem is
wrong, as TestStyle is a subclass of UIComponent, not a subclass of
Container. In the help for UIComponent, there is no color style or property
listed. Plus if you make it inherit from other things like Object,
DisplayObject, Sprite, etc., the error changes to different files, including
saying the file conflicts with itself (Declaration of style 'color'
conflicts with previous declaration in C:\dev\GenericTest\src\TestStyle.as);
If I change it to inherit=yes, it does not have a problem with it. My
best guess is that there's something hidden and undocumented. Doing a
search on all the SDK code found no declaration for it. If I take out my
Style declaration and call getStyle(color) on a newly created TestStyle
object, I get 0x0B333C. So it's getting set somewhere.
Anyone want to offer their two cents? I'm considering filing a bug report
but I don't know exactly if this should be considered a bug (well,
definitely a bug in the compiler error text) or poor documentation or what.

[flexcoders] Anyone written a ComboBox that can take an AdvancedDataGrid as a dropdown?
I find myself in the position of really needing a ComboBox that can take an AdvancedDataGrid descendant in the dropdownFactory. Unfortunately, ComboBox is pretty hardcoded to use ListBase and AdvancedListBase does not inherit from it. Recreating a DataGrid version of my existing ADG descendant will be a total pain. Unfortunately, CombBox is written in such a way that mx_internals and other muck is threaded throughout, making it difficult if not impossible to just clone and replace references to ListBase. Anyone here already tilted at this windmill? -- Jason
[flexcoders] My frustrations with the Adobe Bug Report system
I've put off writing this for a while out of laziness. Going out of my way to report bugs is already sort of outside of the scope of what I should be working on, but I consider it very important for the quality of the product. And it helps that my bugs are typically answered and fixed. But griping about the bug report system itself seemed a little too meta. Plus, I kept debating on whether I should file it as a bug or email it here or dig someone at Adobe's address up or what. So I've settled on this, here goes. Generally, the bug system works well. Yes, it can be a bit frustrating to find out if there's already a bug with the issue you're going to report. Yes, those old bugs imported from the old DB are maddening when the subject line makes you think they're the same. But all in all, it works ok. There are really only a few things that really bug me. Also, I'm sorry for the terrible pun. My main problem is with documentation. There needs to be some explanations as to what choices in the various combo boxes mean so that we, as users, can more intelligently give you feedback. Take for example the bug I'm about to enter. I found a bug in the compiler so that it's not parsing the code right. This happens both in Flex Builder and in mxmlc. I start out and it asks Project. I wasn't sure on the dropdown if it should be ActionScript Compiler (ASC) or Flex Builder. I finally figured out I could go through Browse Projects and click on individual projects to get descriptions of them, though not all of them had descriptions. Even after entering enough bugs to get a t-shirt, it took me this long to find that. There's plenty of room on that first page to have a list of the projects and a short paragraph defining the scope of the project so submitters can more easily pick the project. FYI, I eventually decided on ActionScript Compiler. Next you have the Issue Type. If you click on the little help box, you get this help for feature requests versus minor enhancements: *Feature Request* A new feature to the product. *Minor Enhancement* A new enhancement to the product. I had a better idea about the difference between those two BEFORE I clicked on the help. No matter if you choose Bug, Feature Request or Minor Enhancement, you still get the same list of severities on the next page. So you can choose Bug-Enhancement/Task or you can choose Minor Enhancement-Crash Hang. I realize that this may just be a limitation of JIRA, but it's a little distracting. Along with this, minor enhancements get all the other boxes like Discoverability, Reproducibility, Regression, etc. that really don't apply to them. Feature requests don't get that, but then again there's the whole fuziness about the difference between those two things. Now you go on to choose the Component the bug is found in. I have never found a page that actually gives descriptions of the various components. And some of these leave me scratching my head. Much as with the projects, there should really be an easy way to get a sentence or three about each component so you can more easily decide where to put new bugs. Either that, or force all bugs to go to an unassigned component and let the bug reviewers sort it properly.

I'm using Flex Builder 3 and the compiler is barfing. Help? These are specific to each project, so I'm baffled why so many versions exist for the compiler when generally errors in it will happen before you ever get to the flash player.

I have Flex Builder 3, the current version of FB that is being sold on Adobe's website, and it is the seventh one on the list. I think. Go to Help-Product Details-Feature Details: Flex Builder 3 Version: 3.0.205647 I used to think I had version 3.0.2. Only now as I'm typing this post do I realize that I misread that and if I go here: Help-About Adobe Flex Builder 3... Splash screen comes up and in the bottom right: Version 3.0 (build 3.0.1.205647) Well that's a bit more obvious, isn't it. It should be, I guess, but since there was no 3.0 on the list I though they must have some weird numbering that meant 3.0.205647 was actually 3.0.2 builder 05647. Not a huge quibble, but those version numbers need to be a bit more tightened up. Addendum. I just upgraded

What you are running into is the fact that we have a lot of internal milestones and builds and therefore we want the bug system to be able to reflect those for internal purposes, but I wonder if there is any way we could provide a filter for just the public ones and sort by the most likely for you to encounter them. I'll see what we could do to maybe get some help links for some of the explanations. I don't know that we can explain every features, we may need you to just make your best guess, but at least for projects we can see what we need to do.

Going out of my way to report bugs is already sort of outside of the scope of what I should be working on, but I consider it very important for the quality of the product. And it helps that my bugs are typically answered and fixed. But griping about the bug report system itself seemed a little too meta. Plus, I kept debating on whether I should file it as a bug or email it here or dig someone at Adobe's address up or what. So I've settled on this, here goes. Generally, the bug system works well. Yes, it can be a bit frustrating to find out if there's already a bug with the issue you're going to report. Yes, those old bugs imported from the old DB are maddening when the subject line makes you think they're the same. But all in all, it works ok. There are really only a few things that really bug me. Also, I'm sorry for the terrible pun. My main problem is with documentation. There needs to be some explanations as to what choices in the various combo boxes mean so that we, as users, can more intelligently give you feedback. Take for example the bug I'm about to enter. I found a bug in the compiler so that it's not parsing the code right. This happens both in Flex Builder and in mxmlc. I start out and it asks Project. I wasn't sure on the dropdown if it should be ActionScript Compiler (ASC) or Flex Builder. I finally figured out I could go through Browse Projects and click on individual projects to get descriptions of them, though not all of them had descriptions. Even after entering enough bugs to get a t-shirt, it took me this long to find that. There's plenty of room on that first page to have a list of the projects and a short paragraph defining the scope of the project so submitters can more eas! ily pick the project. FYI, I eventually decided on ActionScript Compiler. Next you have the Issue Type. If you click on the little help box, you get this help for feature requests versus minor enhancements: Feature Request A new feature to the product. Minor Enhancement A new enhancement to the product. I had a better idea about the difference between those two BEFORE I clicked on the help. No matter if you choose Bug, Feature Request or Minor Enhancement, you still get the same list of severities on the next page. So you can choose Bug-Enhancement/Task or you can choose Minor Enhancement-Crash Hang. I realize that this may just be a limitation of JIRA, but it's a little distracting. Along with this, minor enhancements get all the other boxes like Discoverability, Reproducibility, Regression, etc. that really don't apply to them. Feature requests don't get that, but then again there's the whole fuziness about the difference between those two things. Now you go on to choose the Component the bug is found in. I have never found a page that actually gives descriptions of the various components. And some of these leave me scratching my head. Much as with the projects, there should really be an easy way to get a sentence or three about each component so you can more easily decide where to put new bugs. Either that, or force all bugs to go to an unassigned component and let the bug reviewers sort it properly.

I'm using Flex Builder 3 and the compiler is barfing. Help? These are specific to each project, so I'm baffled why so many versions exist for the compiler when generally errors in it will happen before you ever get to the flash player. Of course, this is still probably better than the list of version that comes up when you choose the Flex Builder project: None
[flexcoders] Replacement Date class?
Now that the whole ECMAScript thing has blown over, Adobe is free of being
quite so bound to it as a standard. They've expressed interest in doing
some things that they previously shied away from because of divergence from
the standard.
Is anyone else really interested in ditching the Date class? That thing
drives me nuts. The number one problem is that it's an object. So you get
something like this:
var myDate:Date = new Date(2008, 1, 1);
var myDate2:Date = myDate;
...
myDate2.month++;
It's an easy mistake to miss, especially for beginners, and it can be very
annoying to track done. It's also a pain that you can assign values to the
time, day, month, etc. properties and it screws up data bindings and
setters/getters. For example, if I have:
private var myDate:Date;
[Bindable] public function set myDate(value:Date):void
{
_myDate = value;
invalidateDisplayList();
}
public function get myDate():Date
{
return _myDate;
}
It works great until you do something like:
myDate.time = newDate.time;
or
myDate.date++;
Simliar difficulties exist when using a date dropdown control.
So is it time to get a new Date class? Perhaps a new one called DateTime
and make the old one deprecated.
What I'd love is for it to be a new primitive type (like Number, int,
Boolean) that would be stored the same way as the time property of Date and
would be manipulated through static functions of the DateTime class.
Examples:
var myDate:DateTime = DateTime.now();
trace(myDate:, myDate);
myDate: 1228248636245
myDate = DateTime.incHour(myDate);
myDate = DateTime.incMinute(myDate, 20);
myDate = DateTime.incMonth(myDate, -3);
myDate = DateTime.incHourUTC(myDate);
myDate = DateTime.encode(2008, 1, 1);
var hours:Number = DateTime.getHours(myDate2 - myDate1);
No more date or fullYear - use the much more intuitive day and
year. I would also like month to be one-based, but that'd probably make
enough people grumble that I'd be willing to live without it.
I dream of seeing all the existing controls and such that use Date updated
to use this code instead. I would have already created the DateTime class
if it wasn't for how much trouble daylight savings time, leap year and
internationalization would be.

[flexcoders] any overhead for calling simple getters?
If I have this:
private var _myvar:int;
public function get myvar():int
{
return _myvar;
}
should I try to refer to it in other parts of the same class as _myvar, or
is myvar equally efficient? In Delphi, you can define a property like:
FMyVar: Integer;
property MyVar:Integer read FMyVar;
and all references to MyVar automatically get optimized to FMyVar. But I'm
wondering if Flex optimizes out the unnecessary function call represented
above.

Re: [flexcoders] Can you spare 5 minutes to reproduce this 12 line bug?
Just FYI for anyone reading, the bug has been reopened and the tester has commented. Apparently the problem was that they were alt-tabbing between the flex app and flex builder to see the trace output. Once I posted the version that outputs the null to the screen, they reproduced it. Chalk this up to just providing a user-unfriendly test case. Thanks Maciek and Tom.

[flexcoders] need some help with an effect I made and its glitches
I'm fairly new to making effects, and it's a miracle I have any hair left.
I have created the following effect so that I can transition between various
states of a component. The problem is that I want to reuse the same
component and not make a new one for every different screen. So I'm making
a bitmap snapshot, sliding that one out of the way and sliding in the new
one behind it.
I have two problems. Well, probably more once you read this code, as it's
kinda hacked together. But the two problems that happen are:
1) when the effect starts, the original box disappears then reappears. bad
flicker.
2) when the effect ends, there is a slight hitch at the end that makes it
look jumpy
Any tips on how I can fix these two problems, or any comments on other
errors in the code? Thanks.

[flexcoders] threading, forcing code to run in the main thread, URLLoader, etc.
I've read that Flash Player runs flex code single threaded, with the exception of network calls and rendering calls. So if I have a URLLoader and I add an event to it for COMPLETE, does that event handler code get run in the main thread, or in a separate networking thread? If it's a separate thread, is there a way to run it in the main thread? I'm doing some work with the f-in-box component and trying to sort out some strange problems I'm getting. I will go further into it if necessary, but since most people here don't use it I was thinking a more abstracted question would be more helpful. -- Jason

Re: [flexcoders] what is a String? (default encoding question)
Thousands of rows of columnar data. Doesn't really matter, though. The help for both readUTF and readMultiByte says: Returns String — UTF-8 encoded string. So no matter what I do, it appears the ByteArray can only return UTF-8 anyway. Considering this, I might as well write it to the file in UTF-8. Of course, I suppose that internally ByteArray could read it in as something different, then convert it to UTF-8. So that it would read my UTF-8, convert it to something else, then convert it back to UTF-8 and return it. That would suck but it's impossible to tell without input from the people who can actually see that code. Always frustrating when I bump up against the wall where open source becomes closed.

Re: [flexcoders] force SeriesInterpolate on BubbleSeries to preserve bubble order?
Well, it's been a while but I've finally been able to get back to this.
Unfortunately, there are cases where this simply won't work. For example:
[Bindable] public var d:ArrayCollection = new ArrayCollection([
new ArrayCollection([
{x:1, y:1, z:10},
{x:2, y:2, z:20},
{x:3, y:3, z:30},
]),
new ArrayCollection([
{x:1, y:1, z:20},
{x:2, y:2, z:30},
{x:3, y:3, z:10},
])
]);
There is no way you can rearrange the second data such that it won't screw
up one of the bubbles.
I think I'm just going to have to get in there and hack at it to make it
stop trying it's smart bubble rearranging.

Explication:
Your order is sorted according to Z field and after that the
colors are attributed. So when you change the z value for (1,1) element this
will be second value from red ball (3,3) not (2,2) because the order is made
according to z value.

What happens is that the blue bubble swaps places with the green bubble
and then grows to the size of the green bubble. What I want is for the blue
bubble to just grow in place and have the green bubble stay put. Is there
some way I'm missing to tell the chart to pay attention to the order of the
data? I thought maybe it had something to do with transitionRenderData, but
the documentation on it is rather ... brief.

Will this make your help show up in the context-sensitive help and search results as well, or only in the contents page?

[flexcoders] possible to get bytes from a pre-existing Image?
This question is really part of a larger ball of stuff I'm trying to untangle. Basically, the first part is that if I have this: [Embed(source=logo.png)] public var logo:Class; ... var img:Image = new Image; img.source = logo; Is there any way to get a ByteArray from img that can be fed to Loader? Unfortunately, I'm stuck with Loader. If you really want to know, I'm trying to mess with a TextArea that has htmlText with an img tag in it. I want to switch the img tag to switch between different images that are embedded in the SWF. As far as I can tell, there's no way to tell an img tag to load an image out of the SWF. Feel free to correct me on that. Because of some features of the environment, I really want to embed the images and not load them from the local file system or over the network. Eventually, I actually want to replace the PNG with an SVG. This is part of why I'm wanting to have the files embedded. But I know this will bring further challenges, as SVG is a vector format and I will have to get a raster rendering of the SVG at a certain size before I can ever expect to feed it to Loader. But I'm trying to take it one giant hurdle at a time. Any thoughts, other than that I'm insane to do such a thing? -- Jason
Re: [flexcoders] possible to get bytes from a pre-existing Image?
Excellent tip!
Well, here's what I'm trying to do. I have logos for various companies
embedded in my SWF. I also have various graphs where the logos will be
shown in the datatip popup. The contents of this datatip are returned in an
SQL statement. Why SQL? Because this is an easy place my boss can change
the stuff so he can play with different wordings and layouts without having
me compile the Flex app every time.
So he might change the query to:
select tip = 'Results for logo' from ...
or
select tip = company_name + 'brlogobr$' + convert(varchar, sales)
That's not exactly it, but you get the drift. I want to be able to replace
logo with the appropriate logo for the company for the point on the
graph. It may appear anywhere in the tip text. He could also put whatever
html markup he wanted in the tip text.
Seems to me the easiest and most flexible way would be to use a TextArea or
similiar and set the htmlText property. But of course I need to fill in
logo with whatever the correct logo image is. I want these images to be
embedded in the SWF, so I can't just use img src='http://server/logo.png',
etc.
So what I have done is replace logo with img id='logo' src=''. So an
example would be:
Footronicsbrimg id='logo'br$123456
I might even go back and take out that step and just have the boss put in
img id='logo' src='' in the first place. That way he can control
height/width if he wants to.
Right now, I've got only as far as using a TextArea to try to work out how
to do this. If I assign the above to htmlText, I get an ioerror. So I set
up a handler to cloak that. And using your tip, I find that I can
successfully do this:
var ba:ByteArrayAsset = ByteArrayAsset(new logo);
for (var i:int = 0; i testtext.numChildren; i++)
{
var o:DisplayObject = testtext.getChildAt(i);
if (o is UITextField)
{
var r:Loader = UITextField(o).getImageReference(logo) as Loader;
r.loadBytes(ba);
}
}
Wonderful!
Well, sort of. As I said, what I'd really like to use is SVGs. This method
doesn't work very well with them, I'm sure due to the same problem that
forces you to only be able to use SVGs when they are embedded. If you try
to use an SVG, you just get a continuous stream in the console log of
[SWF] C:\Documents and Settings\\My Documents\Flex Builder
3\...\bin-debug\.swf - 0 bytes after decompression
Over and over again. Bother. I suspect that may sink the whole
ByteArrayAsset approach. Because I suspect I will have to embed the SVG,
then later create an object that will get make a bitmap version, THEN have
the Loader object load the bytes from it. Somehow. If it's even possible.
Unless someone else has a suggestion for a better way to let my boss be able
to type in all this formatted html with embedded logos that are in SVG
format.

Re: [flexcoders] possible to get bytes from a pre-existing Image?
Well, for one thing, the program is a bit up in the air on final
specifications. Sometimes it's running off the network, other times it's
running locally. It's just very handy to move around one single SWF and not
have to drag along all the various logos. It's also handy for the SWF to
have a builtin list of possible logos to use. I admit that part of the
reason is just to see if I could, and therefore to add to the toolbox of
abilities I have.
And I'm pleased to announce that I have succeeded!
There might be a better way to do it, but what I'm doing now is this:
var svg:DisplayObject = new logo;
var bd:BitmapData = new BitmapData(svg.width, svg.height);
bd.draw(svg);
var ba:ByteArray = new PNGEncoder().encode(bd);
for (var i:int = 0; i testtext.numChildren; i++)
{
var o:DisplayObject = testtext.getChildAt(i);
if (o is UITextField)
{
var r:Loader = UITextField(o).getImageReference(logo) as
Loader;
r.loadBytes(ba);
}
}
There's the minor issue of resizing the svg before converting it to a
bitmap. But I've made some progress on doing that. And I'll probably
subclass Text or some component so I can get at textField without having to
iterate through the children.
Thanks to everyone for their help, and I look forward to hearing any further
suggestions, tips or mockery. ;)
I'll try to write up a more complete example for posterity and post it as a
followup.

I was just thinking that if you didn't specify mimeType, it would give

But it looks to me that your main issue is trying to get embedded images

If you know it is just going to be simple html and an icon, you might just
parse the html and generate instances of widgets. See the HTML and Flex
post on my blog
But easiest would be to not embed the logos and let the TextField load
them. I'm not sure why you want to embed the logos. Depending on their
size and quantity and what percentage of them get actually used, it might be
better to get them over http. After the first fetch it should be in their
browser cache.

2) Lighter gray borders (borderColor doesn't work).
3) A thick, solid black line below the headers (border-thickness-

4) Word wrap.
5) If possible, a Windows-style sort arrow on column headers,

Is there a good reference somewhere on Flex CSS?

Re: [flexcoders] AdvancedDataGrid: Exclude last row from sorting
Glad you got the result you were looking for. Yes, it does kind of suck
that they made the sorting method so simple. The problem is that that part
of the code isn't grid code, it's ICollectionView code. It winds up using
SortFields, which are very unaware of any griddish concerns. It's a great
way to do it, from a code design point of view. But sometimes it can throw
a monkey wrench into practical applications.

Hi Jason,
I think I have this working as required now with just the one sort method
used by every column (I think this is OK as I have multi-column sorting
turned off).
I have moved the createColumns() method onto the MyAdvancedDataGrid class
and added the following to that class:
// map of column objects keyed against their datafields (populated by
createColumns() method)
private var mColumns:Object;
// keep track of currently sorted column
private var mSortedColumn:AdvancedDataGridColumn;
public function MyAdvancedDataGrid (id:String)
{
snip
addEventListener(AdvancedDataGridEvent.SORT, sortEventHandler);
}
private function sortEventHandler(event:AdvancedDataGridEvent):void
{
mSortedColumn = mColumns[event.dataField];
}
Then within createColumns() every new column gets
column.sortCompareFunction = compareExcludeSummaryRow;
where the sort method is:
private function compareExcludeSummaryRow(obj1:Object, obj2:Object):int
{
// should never be in this state
if (mSortedColumn == null)
{
// TODO log error
return 0;
}
var isSortDescending:Boolean = mSortedColumn .sortDescending;
var sortField:String = mSortedColumn .dataField;
if (obj1.summary)
{
return isSortDescending ? -1 : 1;
}
else if (obj2.summary)
{
return isSortDescending ? 1 : -1;
}
else if (obj1[sortField] obj2[sortField])
{
return -1;
}
else if (obj1[sortField] obj2[sortField])
{
return 1;
}
else
{
return 0;
}
}
This seems to work nicely now, but as I say I think it is restricted to
single column sorting, which is fine for me.
Thanks for your help, and any further comments appreciated!

[flexcoders] any way to use embedded image in htmlText?
The answer to this is probably going to be no, but I figure it's worth a shot. I have a number of images embedded into my flash application. I would like to allow the user to type some html that would include an img tag that references those images. That would then get applied to a UITextField's htmlText property. Is there any way to do this, or are you stuck with either loading images for htmlText off the network or off the hard drive? -- Jason
Re: [flexcoders] Drag and Drop question
I believe you're going to need to handle the drop events yourself and not
use the dropEnabled=true setting. When you do that, by default drop is
denied and you have to tell it to allow it, like in the dragEnter event.
For example:
private function dragEnterHandler(e:DragEvent):void
{
DragManager.acceptDragDrop(UIComponent(e.currentTarget));
DragManager.showFeedback(DragManager.COPY);
}

Re: [flexcoders] Re: Styling AdvancedDataGrid's header
I THINK I know what you're talking about. You mean the grey line that
separates each column, right? What you're wanting is a line that goes all
the way from the bottom-left of the first column header to the bottom-right
of the last column header, right? If not, please post a doctored screenshot
of how you want the header to look.
If so, I think you'll need to make your own headerSeparatorSkin for ADG.
This is what is in the default skin, DataGridHeaderSeparator.
override protected function updateDisplayList(w:Number, h:Number):void
{
super.updateDisplayList(w, h);
var g:Graphics = graphics;
g.clear();
// Highlight
g.lineStyle(1, 0xFF, 0.5);
g.moveTo(0, 0);
g.lineTo(0, h);
g.lineStyle(1, getStyle(borderColor));
g.moveTo(1, 0);
g.lineTo(1, h);
}
I made my own subclass of ProgrammaticSkin that just had nothing in its
updateDisplayList. That gave me no separator at all. I'm sure you could
get it to do just what you want. You're still left with the default border
around the entire block of columns drawn by the grid. There's probably
another skin you could replace to get rid of that if it's a problem.

the sort order is reversed, and the summary row moves to the first row. Am

Yes, it's fairly easy to do with a custom sort function. Here is an

if (obj1.summaryRow)
return -1

Where fieldbeingsorted is the field for that column that would
otherwise
be sorting on. For example, if you had
AdvancedDataGrid dataField=customerName
sortCompareFunction=copmareWithSummary/
then fieldbeingsorted would be customerName. You'd need to make a
different
compare function for each column in the grid, since Flex doesn't pass in
the
column name to the sort compare function.

Here are the things I'm trying to do:
1) Left-aligned text (text-align doesn't work).
2) Lighter gray borders (borderColor doesn't work).
3) A thick, solid black line below the headers (border-thickness-
bottom doesn't work).
4) Word wrap.
5) If possible, a Windows-style sort arrow on column headers, instead
of the wierd blocked-off sort arrow used by Flex. I'm guessing I'd
need a skin for this.
Is there a good reference somewhere on Flex CSS?

Re: [flexcoders] Copying graphs to the clipboard
As an AIR app, it should definitely be much easier. With it, you have access to flash.desktop.Clipboard. When flash is running in the browser, it's subject to a lot more restrictions. You can call System.setClipboard to copy a string to the clipboard, but that's pretty much it. Different browsers have different rules/methods for accessing the clipboard from Javascript. Here's a page on how to do it in IE, but you'll get a security warning in more recent versions: http://www.codehouse.com/javascript/tips/clipboard_send/ There's a config option in the more recent versions of Firefox to allow clipboard writing from javascript: http://www.febooti.com/support/website-help/website-javascript-copy-clipboard.html I'm not up on how each different version treats these things. Furthermore, if you have to support users of Safari, Opera, or even Chrome now, you may run into issues. Not sure if you need it, but I ran across this article for actually creating the snapshop in Flex using the new ImageSnapshot class: http://dougmccune.com/blog/2007/06/11/imagesnapshot-class-in-flex-3-sdk/ On Sat, Sep 13, 2008 at 1:20 AM, Guy Morton [EMAIL PROTECTED] wrote: Has anyone got any advice as to how one might allow a user to copy a graph to their clipboard (or save it as a file)? I'm sure I'm not the first person to ask this, so if there is an authoritative copying data from Flex FAQ somewhere please let me know. We'll be building this app in Flex 3. We can do server-side stuff if need be, but we're not running CF or Flex data services. Also, if we were able to distribute the app as an AIR app, would we have access to vastly better options?

Re: [flexcoders] AdvancedDataGrid: Exclude last row from sorting
Yes, it's fairly easy to do with a custom sort function. Here is an example
function that assumes you set a summaryRow property on the last row
object:
private function compareWithSummary(obj1:Object, obj2:Object):int
{
if (obj1.summaryRow)
return -1
else if (obj2.summaryRow)
return 1
else if (obj1.fieldbeingsorted obj2.fieldbeingsorted)
return -1
else if (obj1.fieldbeingsorted obj2.fieldbeingsorted)
return 1
else
return 0;
}
Where fieldbeingsorted is the field for that column that would otherwise
be sorting on. For example, if you had
AdvancedDataGrid dataField=customerName
sortCompareFunction=copmareWithSummary/
then fieldbeingsorted would be customerName. You'd need to make a different
compare function for each column in the grid, since Flex doesn't pass in the
column name to the sort compare function.

Re: [flexcoders] Not able to capture event dispached from custom state override - what's wrong?
You need to register your event handler with the object actually dispatching
events.

...
mytest.addEventListener(testEvent, handleIt)

Re: [flexcoders] Browser Bug ? Display 2 scrollbars
It would probably help a lot if you can post a small test app the shows what you're talking about. Keep it as simple as possible to illustrate your problem. But my first instinct is that it's kind of an age-old problem in programming with scrollbars. Say you have an element that is 500 pixels wide, just wide enough to show everything it contains. Then it gets a lot of info in it, which causes it to need a vertical scrollbar. Well, that scrollbar then steals some width from that 500, so that now the element can only be, say, 484 pixels wide because there's a scrollbar taking up the next 16 pixels. Well, now if you have scrollbars set to automatically pop up when the element isn't wide enough to display the text width, the horizontal scrollbar shows up, too. The fix for this in flex is to set the horizontal widths as a % of the parent's width. That way when the vertical scrollbar pops up, the element and hence its children will resize to be smaller to accomodate the scrollbar. If this isn't clear, post your example and I can show you the changes to fix it. On Wed, Sep 10, 2008 at 6:19 AM, itdanny2002 [EMAIL PROTECTED] wrote: I create Vbox with fixed width. Then I add Canvas inside. Afterwards, I add TextArea as child. Scrollbar policy of canvas is off. If there are many childs but within boundary e.g. 700 pixel. No scrollbar. If it is over screen height e.g. 900 pixel. It displays scrollbars. Anyway, it displays TWO: Vertical and Horizontal. I try to set MaxWidth but still has 2 scrollbars instead of just vertical. More information. I add TextArea child programmingly. I trace the width of Canvas. The width is longer than what I expect even in startup mode. Any idea ? -- Jason
Re: [flexcoders] How to do a State Change Area Chart with Time Series State Change Source Data?
This shouldn't really be hard at all. Have you actually tried it and are running into difficulties? You need to make sure your x values are in the format that Date() likes, and if using a DateTimeAxis doesn't work, you can use a LinearAxis and a custom axis label function. If you want a stairstep instead of a straight line between points, that's also possible with a certain property/style of the series.

Note in the first instance, above, the state was ON for only 4 seconds. We need to see that on the graph, as a visible line, even though the graph might be displaying for six months. We need to display this graph for a defined period with each ON state change being represented by the area chart showing as 1 on the y-axis. So can we pass this data to a flex chart and have it represented as an area graph? I would hate to have to generate millions of values to achive this. Four months of one second data is about 10,368,000 lines of data! Any ideas on an approach? TIA Cheers Mark -- Jason
Re: [flexcoders] Bug ? IE FireFox Menubar
I believe you're just running into how different browsers handle embedded flash objects. Once you click on a flash app, firefox generally lets it have every keystroke after that until you actually click somewhere outside it. IE is less permissive and continues to listen for keystrokes even when a flash app is focused. Once you click outside a flash app in either browser, your browser no longer receives keystroke messages because it's no longer focused.

Re: [flexcoders] Custom vertical axis line on plot chart
There are several ways you could go about doing it, though nothing built in to support it. One way would be to make your data so that 30 is actually 0 in the underlying data. You'd write an axis label function that would add 30 to the values for labelling. If you wanted datahints, you'd have to write a function to do the same for them. Then you'd set the major tick interval really high so that you'd only ever get a single grid line at your fake 0 point. Another way would be to create a ChartElement that just draws a line at 30 and stick it in the BackgroundElements, along with a GridLines that is set to horizontal only (if thats what you want).

Re: [flexcoders] Date field in either arraycollection or datagrid
For #2, look at ArrayCollection.sort. You can create a sort object and use a slightly modified version of your date_sortCompareFunc for the compareFunction of the Sort object. I've never really found a good way to do #1, so I'd be interested in that if you or anyone else finds a way.

However, when the datagrid is populated it needs sorting so i think the 2 options i have are either, 1) call something to do this sort as if someone has clicked on the header 2) sort the array collection on the date field. any thoughts on how i could do either of these and it will be greatly appreciated.

Re: [flexcoders] Flex Charting Issue with Data Effects
Okay, I think I figured it out. I had the same problem in the 3.1 SDK. You were definitely being stumped because you didn't have the Pro source code. I went ahead and created a bug and entered the reason it's broken and how you can go about working around it.
