[flexcoders] Weird font issues
Hi there I'm experiencing a strange issue where when compiling running my project with FlexBuilder, text in a custom implementation of Flex's new text-layout control periodically disappears and re-appears, or just doesn't display at all. I put this build (debug or release) up for my collegues to test and it runs fine for them. Also, if they check the project out of svn debug / compile it, it works fine. Previously before installing Snow Leopard I was running Leopard and had a similar issue, where my font for this particular control was smaller and bolder on my computer than it actually was / had been designed to be - on everyone else's computer it was not bold was bigger even though I created all the build releases. I assume the issue I'm having now is related because I create the release builds don't see the font, but everyone else can. I have done a clean reinstall of Snow Leopard ... so it's very unlikely that there are any cached settings that were responsible for my initial issue. Cheers Tracy
[flexcoders] Re: Special characters (eg. Cyrillic) TextArea
Thanks Andriy for your help I've managed to track down the issue (but not explain it) One of our team - also using Mac OSX - built his project using a manually updated version of Flex 3.2 sdk (versus updating to flexbuilder 3.0.2, which automatically udpates to the 3.2 sdk) If I build the exact same project (same checked-out items from SVN), cyrillic in a release build works fine. Since then he has upgraded to Flexbuilder 3.0.2, so theoretically he should have the same environment as me. He has since built new swc versions of his component and we still get issues with typing cyrillic in a textarea. For now at least there is the work around that I can build a version of his component to be used in my project and cyrillic / special characters will always work. It is strange that with his updated environment which is the same as mine, there is some incompatibility that is causing special characters not to display properly (now this occurs in release as well as debug builds) Cheers Tracy --- In flexcoders@yahoogroups.com, Andriy Panas a.pa...@... wrote: Hi Tracy, Are you using Safari browser under Mac OS 10.6?

[flexcoders] FlexBuilder - Release Build - Cannot type Cyrillic foreign characters
Hi there All of a sudden when creating a release build of my application, users are not able to type Cyrillic other foreign characters into textareas. If I test on a debug version I am able to enter in these characters, but not if I make a release build. This is strange because I have made hundreds of release builds before and never come across this problem. The last successful release build I made where it definitely worked was 19 Nov 09. Cheers Tracy
[flexcoders] Re: Flex Debug Problem
Hi there I managed to find a solution to the problem. It has to do with outdated app xml config files (which I think don't get committed into source control) So after importing my project from source control, I create a new application (eg. Test) and run / debug it, which works fine. Compare the 2 app xml config files. In the new file at the top you will see a line: application xmlns=http://ns.adobe.com/air/application/1.5; In the old file I had: application xmlns=http://ns.adobe.com/air/application/1; I actually copied all the data over from my original app to the test app, but if you replace just that line of xml, the original project should run fine.

[flexcoders] Re: How can I populate the data in PopUpMenuButton?
I have never worked with an AdvancedDataGrid, but for a regular DataGrid I
would do the following:
- create a new component that will be the item-renderer (possibly extend
DataGridItemRenderer)
- this new component would contain a popup-menu component
- at this component level you have access to the 'data' property of that item,
which would hold any information, such as urls / links
At this point I'm not clear with what u are trying to do, but you have various
events / options open to you. Such as ListEvent, where you can set up a
listener on your DataGrid. For example, itemClick:
myDataGrid.addEventListener(ListEvent.ITEM_CLICK, onDataGridItemClick);
private function onDataGridItemClick(e:ListEvent):void {
trace(e.itemRenderer.data); // here you have a handle to either the component
itself (e.itemRenderer), or the actual data
}
Cheers

[flexcoders] Performance, Event Listeners and removedFromStage
Hi I know it's good practise to clean up event listeners to improve on performance. I see 2 ways of doing this: - Explicitly clean up listeners (using removeEventListener(...)) - Specify 'useWeakRefrerences = true' when adding the event listener (addEventListener(Event.ADDED_TO_STAGE, onAddedToStage, false, 0, true)) I usually implement both, explicitly removing events where I can. I also don't trust the latter to be as effective as explicitly removing listeners - is it as effective? I have a bunch of item-renderers that have at least 4 event listeners. I set up these events to use weak references. To be 100% safe I also want to explicitly remove the listeners. So I listen for the 'removedFromStage' event, where I explicitly remove the listeners. Enter problem ... The 'removedFromStage' event is called when an item is initialized. Flex does some weird drawing initialization which ends firing 'removedFromStage' when the components initially load up. This results in my event listeners being removed even before the component has loaded and my item-renderers no longer work. So, what is the solution? - Can I rely on the 'useWeakRef' attribute to clean up the listeners(I have 100s of item-renderers)? - Where could I explicitly remove the listeners if this is the correct way of doing things? - Why is 'removedFromStage' called at such an illogical point in the creation of components? Cheers Tracy
[flexcoders] Custom Components - updateDisplay results in ghost children drawn
Hi
I've been working with custom components only just noticed a strange
re-drawing issue where I get ghost versions of the children in my
component appearing.
I've only just noticed this since I set the child's position relative
to unscaledWidth, which changes and so allows me to see N different
older versions of the child. This is quite worrying because this means
in my other versions where I the child position is static there are
possibly N occurances of my child component.
Why would this ghosting be happening and is there anything one can do
to purge older instances?
Here's a screenshot of the ghosting:

[flexcoders] Interesting XML performance discovery
Hi there
I'm busy crunching through xml data, stripping out nodes that don't
have children. Perhaps its not the best way to do things, but I use a
for loop that checks and deletes any item with no children. I've
always found XML delete tricky and to do this I reference the parent
which finds the child index and deletes the child.
On a file of 1+ items execution time is 600ms without the delete.
With the delete execution time is 52919ms!
I'm off to find another delete function ...
for each(span in body.span) {
if(span.children().length() == 0) {
delete span.parent().children()[span.childIndex()];
}
else {
[EMAIL PROTECTED] = SPAN_PREFIX + id++;
[EMAIL PROTECTED] = itemClicked('[EMAIL PROTECTED]',
AIR.itemSelected);
[EMAIL PROTECTED] = span.attribute(class);
}
}
[flexcoders] Re: Interesting XML performance discovery
... just discovered how terribly unoptimized code can be.
Changed the delete code snippet from the below example to the following:
delete body.children()[count]; // takes 53636ms
and then the following:
delete spans[count]; // takes 852ms
Obviously constructing a child array each time in the loop on a large
list of children is hugely inefficient.

This excludes the HTML tags though. I've tried using my HTML component's textSnapshot property this has a charCount of zero. Does anyone have good suggestions on how to get: a) the parent tag or id of a selected piece of text either via AIR or JS b) how to get the raw text of a selection (that includes tags) via AIR or JS Thanks Tracy
[flexcoders] Skinning in Flex - What a nightmare!!!
Please help
There is virtually no documentation on Flex skinning. I am really
struggling with border sizes and content sizes with custom skins, in
particular Panel skins using the borderSkin property.
I'm currently trying to skin an Alert box. I have the following
properties set:
Alert {
color:#ff;
borderSkin: Embed(source=flex_skins.swf, symbol=Panel_popupSkin2);
headerHeight: 30;
paddingTop: 20;
paddingBottom: 4;
}
My content only just fits, after much pixel pushing. It is still not
perfect as it is all squashed in. I have tried various things, that
have had no effect such as:
- tweaking the scale-9 borders in the .fla symbol
- setting verticalGap in the style
- setting borderThickness in the style
This is very frustrating as there only seems to be 1 definitive
document on skinning[1] which doesn't cover detailed concepts like how
to structure the .fla symbols.

[flexcoders] UIComponent children, preventing scale on parent scale
Hi there I have a UIComponent that has a collection of Bitmap children. I want parts of these children to not scale when the parent container scales (i.e. scale-9 for these children). I have set scale-9 for each child instance, but they still scale when the parent. I can simulate this scenario using a Canvas with linkbuttons as children, where the linkbutton icon is the bitmap that shouldn't scale. I could do it this way, but I rather want to have this at a lower level - on a UIComponent level. Cheers Tracy

[flexcoders] Flex Binding Issues
Hi there
I've run into binding issues with Flex 3B3. I have the following setup:
- TitleWindow with a singleton TitleWindowController that gets
initilaized in TitleWindow.onInitialize()
- DetailsWindow which sits inside TitleWindow and has a getter /
setter of 'controller' for TitleWindowController. It also contains a
Text component whose text value is bound to
TitleWindowController.instance.currentItem.title. Binding is set
throughout the chain of references.
I have this exact same setup 1 level higher, which works fine.
Setting a breakpoint in DetailsWindow at the line:
mx:Text id=titleField text={controller.currentItem.title} /
confirms that controller.currentItem.title has been set. For some
reason the Text.text is not updating. I have tried various methods
like myDetailsWindow.validateNow() and .invalidateProperties() once I
have set currentItem, but nothing happens.
Tracy
[flexcoders] Re: Flex Binding Issues
... one more note ...
If I explicitly bind the properties using BindingUtils in the
DetailsWindow.onCreationComplete event like:
private function onCreationComplete():void {
BindingUtils.bindProperty(this, controller,
TitleWindowController.instance.view, controller);
}
... binding works

Hi Juan Our ScrollBar arrow turned out to be a Bitmap, so you were right about scale-9 not being picked up for Bitmaps. Changing that to a vector fixed it. The scale-9 issue seems to only be a problem for ComboBoxes. Our ComboBox arrows are vectors and we are developing in FlexBuilder 3 Beta 2. Is it possible that the Flex 2 bug still exists for some cases in FlexBuilder 3? I use the same arrow now for our scroll-bar, which works fine in the ScrollBar case, but not the ComboBox. Cheers Tracy --- In flexcoders@yahoogroups.com, scalenine [EMAIL PROTECTED] wrote: Are you using bitmaps as skins in your Flash file? If so, I don't believe scale-9 will punch through to those bitmaps in either scenario. You would have to pull those bitmaps out of the Flash file as separate assets. Regarding the arrow getting stretched, are you using Flex 2? The reason I ask is because in Flex 2 the arrow icon has to be part of the ComboBox, thus it will stretch even with scale-9 applied to it. You could try to change this by setting both vertical scale grids above o below the arrow. However, if you are using rounded corner those would end up getting stretched. Other wise you might have to create different skins for ComboBoxes with different heights. I believe the issue is being resolved in Flex 3 with a new property called arrowIcon making the icon separate from the skin so the skin scales separately from the arrowIcon. I'm not sure about the ScrollBars. I've found that sometime adjusting the scale grids on the ScrollBar arrow skins can fix the issue. HTH, Juan

Hi Tom
That wouldn't work because item is the assigned object in the

newDict[item]=myDict[item], where item would be the key reference in
newDict, while myDic[item] is undefined.
I eventually gave up trying to iterate through a dictionary assign
its child values. The other alternative was to create an array of
keys, iterate those assign the dictionary values to the new dictionary.

[flexcoders] Tab Width Issues when Extending TabBar for TabNavigator
Hi There
I am extending the TabNavigator (actually SuperTabNavigator) class and
have the corresponding children classes that extend TabBar and Tab
(SuperTabBar and SuperTab).
What I want to do is include a 2nd text field in my custom tab that is
displayed next to the existing textField. I'm getting issues with the
Tab width, which seems to be set somewhere outside of measure, where
my custom text field's width is not included in the calculation gets
cut off.
I have managed to get past this problem by including the 'width'
property when overriding measure:
override protected function measure():void{
super.measure();
width = measuredMinWidth = measuredWidth = measuredWidth +
customField.textWidth;
invalidateSize();
}
Now I'm having the issue of the TabBar size not updating the tabs
scroll along the top because they are too large for the parent container.
My questions are:
a) Is this the correct way in going about updating the tab width, or
is there a better way of doing it?
b) How would one get the parent containers width to update accordingly.

[flexcoders] Flex Preloader, not displaying immediately
Hi There I'm experiencing some issues with the default Flex preloader. It used to display immediately in our application but now recently as the app loads there is a blank white screen for the bulk of of the upload the preloader displays for a short instance just before the app load completes. I used Charles to simulate a slow download speed - although not sure how accurate an experience it will present - and it shows a white screen while downloading the bulk of the main swf. I have tried initializing adding the main view to the stage in the onComplete event, but there isnt much difference. Our app is quite large (2mb+) and there are a lot of data connections being made in the app's initialize event. The only things that have changed since we noticed the preloader not appearing immediately is upgrading to FlexBuilder 3 beta 2 and our app getting slightly bigger. Any suggestions? Cheers Tracy
[flexcoders] Actionscript: Copy an Object or Dictionary

Huh?
@Tom
How would one bind the keys to the new dictionary children?
var newDict:Dictionary = new Dictionary();
var item:Class
for each(item in myDictionary) {
newDict[?] = item;
}
@ben
If I have an object containing types (in my case a collection of Class
types referenced by a key string). Using the ObjectProxy.copy(), the
new object will contain child objects with the same keys as the
original, but the child types are Object types, not Class types.

[flexcoders] Overriding inherited skin style
Hi there
I have a global Panel style defined, which contains a border-skin swf.
I want to be able to turn this off for specific panels. There seems to
be no explicit way to turn this off (Eg. boder-skin:none) the only
way I have managed so far is to reference a transparent / blank swf as
the skin. The problem with this though is background colour is then
ignored I get a transparent panel, which I cannot really style.
Another alternative is to create the global panel style as a styleName
reference it in each component in question. But there are more
components using this style than not, so it makes more sense to switch
it off for special cases.
Here's the code:
Panel {
borderSkin: Embed(source=flex_skins.swf,
symbol=Panel_borderSkin);
}
CustomPanel {
borderSkin: Embed(source=empty.swf,
symbol=Panel_titleBackgroundSkin);
/*None of the following styles are implemented*/
backgroundColor: #1b2c36;
border-alpha:0;
border-thickness:0;
border-style:none;
}

[flexcoders] FLV Recorded stream contains strange additional blank space / frames
Hi there We're recorded a series of flv files using getCamera() Red5. Some of our recorded flv's have a chunk of dead video space at the begining. Using RichFLV to analyze the timeline, one can see a few key frames, then a huge chunk of blank space spanning for about 1 minute, then continuing key-frames that follow on from the initial keyframes. This throws out our cue-point calculations because it offsets the video playback time. Help! Tracy
[flexcoders] Re: What do you do when you're waiting for moxie to build?
My Flexbuilder slowness has reached a new record high. After thinking that 3mins was completely unbearable, the new record is approaching 8minutes. This is with all possible attempts / options of setting FB up for optimal build time. I am working with a library project which i build then copy over to my main project which I then build manually, which then takes its record breaking 8mins, even for a small line of code change. Next I debug the project. And of course the whole process has to start over if there was a compiler or runtime error. So, apart from complaining dismally about it, here are the various attempts I have made to improve on build time 1) Uncheck the following Flex Compiler options - Copy non-embedded files to output directory - Verify digests - Enable integration with browser navigation (deeplinking) 2) Turn of 'Build Project Automatically' 3) Reference only SWC's of external library projects, not the projects themselves 4) Make sure un-used projects are closed 5) Build main project manually before debugging it 6) Clear the .metadata folder - this occurs about 3x week, when FB becomes confused unusable 7) Restart FB, restart my computer, delete my files in my Temp folder - this is more out of frustration, no difference has ever come out of these. Is there anything else can I do ... up the memory used by eclipse? Recently my FB has started crashing, a symptom of insufficient memory. I'm running a 2GHz 2GB RAM processor, my library project is 500k, while my main project is 1.8k. Recently there are a lot of fonts being embedded (660k) which brought on this record-breaking time. I have tried using the StyleManager.loadStyleDeclarations to try improve on compilation time, but this brings it's own set of troubles, like my app not loading properly. So what do u do while waiting for moxie to build? Write a long-winded complaintive post about its slowness. I cant wait for the next release!!! Tracy
[flexcoders] [Bindable] not binding
Hi there
I've used the [Bindabe] meta-tag 100's of times, but for some reason
it seems to have stopped working.
I have a very straight-forward setup with a controller, properties and
a view. I have a bindable reference to the controller in the view,
while the controller has a bindable 'title' property.
Setting breakpoints at various steps of the code I can confirm that
the 'title' property is bound to the label in the view (titleText.text
= My Title), yet it is not displayed. I even tried
view.validateNow(); to try force validation / displaying of the label.
What could I be doing wrong, is there possibly a bug in the new Flash
Player that isnt updating bound properties correctly? This is the 2nd
time I've come across this in 3 days.
Here is a summary of my code:
View.mxml
-
[Bindable] public var controller: QController;
mx:Label id=titleText text={controller.title} fontWeight=bold /
QController.as
--
[Bindable]
public function get title():String {
return _title;
}
public function set title(value: String):void {
_title = value;
_view.validateNow();
}

[flexcoders] Re: @Embed directive in mx:source tag not working for swfs
I have experienced something similar think it is to do with the different paths for design view vs runtime view. Runtime uses the assets in the bin folder while compilation design view use the assets relative to the project folder. Just check that assets are found in both. Alternatively you could change the file path to /resources/flashcs3/PhotoAppTheme.swf' - which should indicate the root folder. I have found this not to always work though.

[flexcoders] Flex Fonts: How to implement the Bitmap text (no anti-alias) effect in Flex
Hi there Flash 8 and up provide an option in the property panel for textfields, Bitmap text (no anti-alias). I can use this with embedded fonts to get clear text without depending on the user having the font installed. How do I do this with the Flex compiler?

[flexcoders] Detect focusOut on Application / Stage
Hi there I would like to detect a user entering and exiting a Flex app. My initial assumption was to use FocusIn/Out on either the generic stage / application objects: stage.addEventListener( FocusEvent.FOCUS_IN, onFocusIn ); stage.addEventListener( FocusEvent.FOCUS_OUT, onFocusOut ); This appeared to work initially, but actually the events are triggered when focus changes within components on the stage. The only other option I can think of is the mouseLeave event for stage. The only problem with this is that it is too broad. I'm specifically looking for focus in / out the app, not a mouse leaveing the app, while the app still has focus. Any help much appreciated Cheers Tracy

[flexcoders] HDividedBox - on-release-outside + updateAfterEvent problems
Hi there I have an HDividedBox control that divides 2 children that resize with dragging.

I went a step further and dispatched a DividerEvent.DIVIDER_RELEASE event from teh MOUSE_UP state, which is caught by the divider, however, the state of the divider still doesn't change it still has focus ... Any advice?? Thanks Tracy

So I'll enjoy the simplicity of Flex while I can :) Cheers Tracy --- In flexcoders@yahoogroups.com, Gordon Smith [EMAIL PROTECTED] wrote: It sounds like you want components which are both very rich and very lightweight. If we knew how to do that, we'd write the Flex components that way. : ) Seriously, athough we've tried to balance these concerns in the Flex framework components, we realize that they don't meet everyone's needs. Iff you're extending Button, then you're bringing in significant chunks of the Flex framework, because even a lowly Button supports measurement, layout, CSS, skinnability, focus management, tooltips, etc. The source code for our components is freely available. You might want to consider starting with ours and trimming out the functionaliry you don't need rather than starting from scratch. - Gordon
[flexcoders] Importing mx packages into AS3 project
Hi there I have an AS3 project want to use the rich Flex components (since AS3 components are non-existant and I dont feel like re-inventing the wheel). I recently discovered that u can only use these in a Flex project. The reasons why I wanted an AS3 project was to leave out all the heavy stuff that a Flex project brings along. So I thought that I could cheat, but it looks like it isnt working ... I created a new Flex project, where I created a FlexButton AS3 class that extends mx.controls.Button. I referenced this project in my pure AS3 project, in the hopes of it loading the button compontents all its useful functionality. It looks like this isnt going to work, getting the error in my Flex project: The definition of base class Button was not found. Can anyone confirm that this is not possible. Has anyone found a solution to rich widget controls for pure AS3 projects? Cheers Tracy

How are you embedding the font? Hi Daniel I wasnt embedding the font at all other than specifying the embed property, since I assumed that it was done automatically through the compiler. There was another part in my app where I was manually embedding Verdana letters A-H. So it turns out that one has to manually specify font embedding, typically via an embed tag: [Embed(source=C:/WINDOWS/Fonts/Verdana.ttf, fontFamily=Verdana)] Googling this I also found a lot more on the topic, and of course (rtfm) the help files :) http://www.tink.ws/blog/embedding-fonts-in-as3/ http://www.db75.com/new_blog/?p=114 Cheers Tracy
[flexcoders] TextField.embedFont strange behavior
Hi there I'm getting a strange error when dynamically adding a TF and turning on the embedFonts property. Without the property turned on, all the text is displayed, but with embedFonts set to true I only see the text up to 'ABCDEFGH'. This is very odd behavior, am I missing something blatantly obvious? Code: var fmt:TextFormat = new TextFormat() fmt.font = Verdana fmt.color = 0x99 var toc:TextField = new TextField() toc.antiAliasType = AntiAliasType.NORMAL toc.autoSize = TextFieldAutoSize.LEFT toc.selectable = false toc.multiline = true toc.defaultTextFormat = fmt toc.embedFonts = true Tracy

Thanks Claus
I was meaning more whether it is possible to put 2 classes in 1 .as
file, within a single package definition. So far, it looks like this
is not possible.

[flexcoders] Multiple classes per package
Hi there
Does anyone know if Actionscript 3 and Flexbuilder2 support multiple
classes per package, where only 1 class is declared as public, while
the remaining classes are only available inside the package?
Eg.
package mypackage {
public class MainClass {
public function MainClass() {}
}
class HelperClass {
public function HelperClass() {}
}
}

[flexcoders] Embed an image for a Sprite
Hi there
How does one attach an image to a sprite class?
I have tried the following example, but nothing gets displayed on the
screen:
package
{
import flash.display.Bitmap;
import flash.display.Sprite;
public class MySprite extends Sprite{
[Embed(source='/assets/board.png')]
public var MyPhoto:Class;
function MySprite()
{
var pic:Bitmap = new MyPhoto();
this.addChild(pic);
}
}
}
Thanks

[flexcoders] Re: Embed an image for a Sprite
Ok, I managed to figure out what the problem was from a previous post
- one cannot add a sprite directly to a container, one has to first
add it to a UIComponent type.
Anyone with more info / experience with this?
Cheers
Tracy

[flexcoders] Event listeners: Removing a listener prevents future added listeners
Hi there I'm struggling with a series of KeyboardEvents. Here is the scenario: - I have mouse-down and mouse-up event listeners for my UIComponent. - In the mouse-down event I add a new listener for key-up(so that I can capture mouse-down + a key pressed) - I remove the key-up listener in the mouse-up event The functionality works fine for the 1st time I have my mouse-down - i.e. the key-up event fires when I hold my mouse down and press a key It doesn't work the 2nd time, once I have un-pressed my mouse (firing the mouse-up event removing the key listener) and pressing my mouse again (firing the mouse-down event, adding the key listener) It does however work if I explicitly dispatch a KeyboardEvent.KEY_UP Any expertise on this?

[flexcoders] Overlying UIComponent prevents click event
Hi there I have an Image control that sits ontop of a button. I am trying to capture the click event of the underlying button, but it looks like the overlaying image is blocking access to the button. How can I disable this behaviour? The actual setup is slightly more complex: parent canvas: - button container (Canvas) -- button items (Button's) - image container (Canvas) -- image items (Image's) --- image item button or hit area (Button) Thanks Tracy -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.com Yahoo!
