How can I initialize all TabNavigator Tabs upon a state change?

Here's the basic goal. I want to provide two views to the
user that display the same panels. I configured each view as a
separate state but I am having trouble initializing each of the tab
views since they are only created by Flex when the user first
selects it. I need them all created when the user changes to that
state so that I can insert my view objects. Does that make sense?
Ok, how about an example program. I define three view objects
in ActionScript which will be used in two different states. I use
AddChild to put them in the proper layout location. The problem is
with the Tab state. The AddChild operation only works for the first
tab because it is visible. The other two tabs don't get setup
properly. Can anyone help me resolve this?

Ok, here is an even simpler scenario. I take each view from
the default state and put them in the new tab view when the state
changes. If you compile and run this example, the only view that
makes it into the tabview is the one that was active when the state
changed. Why is that?

Flex 3 TabNavigator getting tab name when tab clicked

Hi All, I am using Flex 3.
I have <mx:TabNavigator id="dbtabs" width="100%" height="100%" click="changeTabs()" />
I am also adding tabs dynamically.
In the grand scheme of things, I want to let a user add tabs as needed and chose what content is on the tab. This is saved data, so when they come back I need to reload their saved settings.
What I am trying to do is find out how to get the index of the tab when it is clicked. Right now I have to click the tab then click in the vbox to get the selectedIndex. Is there a way to get the selectedIndex as soon as the tab is clicked?
Thanks.

private function handleTabClick(evt:IndexChangedEvent):void
       var i:int = evt.newIndex;
<mx:TabNavigator change="handleTabClick(event)">
        <mx:Canvas width="200" height="200" label="Tab 1"/>
        <mx:Canvas width="200" height="200" label="Tab 2"/>
</mx:TabNavigator>

How can you change the style of a flash tabnavigator with css

I'd like to change the colors of a tabnavigator in flash
form.
I found an example how to change the layout for a panel but
it doesn't inherate it to my tabnavigator.
Here a simple example for a panel that works:
quote:
<cfsavecontent variable="contentPanelStyle">
panelBorderStyle:'roundCorners';
backgroundColor:#EFF7DF;
headerColors:#CBEC84, #B0D660;
</cfsavecontent>
<cfform name="myform" width="420" format="Flash"
timeout="100" >

<cfformgroup type="panel" label="With styles"
style="#contentPanelStyle#" width="400">
<cfinput type="text" name="someinput" label="your name"
/>
</cfformgroup>
</cfform>
Actually, I just want to colorize my tabnavigator items
(don't want even a panel around it). How can I do this, as example
with the same colors like the panel?
pawel

Found 1 solution for the active Tab
quote:
<cfform name="myform" width="420" format="Flash"
timeout="100" >
<cfformgroup type="tabnavigator"
style="themeColor:##CC0000;">
<cfformgroup type="page" label="Tab 1">
<cfinput type="text" name="someinpu1t" label="your name"
/>
</cfformgroup>
<cfformgroup type="page" label="Tab 2">
<cfinput type="text" name="someinput2" label="your name"
/>
</cfformgroup>
</cfformgroup>
</cfform>
But still, how do I controll the colors of the inactive Tab
and the highlight Tab (rollover mouse)?

How to access a function in a tabnavigator container?

I have a tabNavigator container that I create the tabs using
the following code:
var tabFieldsBase1:Canvas = new Canvas();
var _userFields:userFields = new userFields;
tabFieldsBase1.label = "User Fields";
_userFields.id = "userFields";
tabFieldsBase1.addChild(_userFields);
tabHolder.addChild(tabFieldsBase1);
inside the tabed document/class I have a function/method
named: startMeUp(). How can I call this function in the currently
active tabed class using AS3 in my app?
I've tried many ways including: var testTemp:Object =
tabHolder.selectedChild.getChildAt(0);
testTemp.startMeUp();
userFields.startMeUp();
Thanks for the help;
Carlos

Thanks Tracy for your input, I think my problem is
understanding Flex 2 scopes properly.
I'm under the impression that when you create an mxml file
compoenent that Flex 2 converts that into an AS2 class, but I guess
not.
I solved this situation by using Actionscript 3 classes to
build my tabs. Now when my main form changes I'm able to
automatically synchronize the displayed tab by calling a method in
the class.
Thanks!!

Tabnavigator with swfloader problem

Hello,
I'm trying to run a tabnavigator component with each tab having a separate swfloader. Each swfloader is a different datagrid that I populate with the SystemManager.application['functionName'] = 'parameters' method.
My problem is that when I a few tabs, only the very last tab's datagrid will have data, and the others will be blank. What's wrong with it?
            public var matrixLoader:SWFLoader;
            public function addTab(tabName:String, swfURL:String, setFunc:Array, searchString:Array):void {
                var tabCanvas:Canvas = new Canvas();
                tabCanvas.label = tabName;
                tabCanvas.id = tabCanvas.label;
                tabCanvas.horizontalScrollPolicy = "off";
                tabCanvas.verticalScrollPolicy = "off";
                functionName = new Array(setFunc);
                paramString = new Array(searchString);
                matrixLoader = new SWFLoader();
                matrixLoader.minHeight = 100;
                matrixLoader.minWidth = 100;
                matrixLoader.percentWidth = 100;
                matrixLoader.percentHeight = 100;
                matrixLoader.addEventListener(FlexEvent.UPDATE_COMPLETE, created);
                matrixLoader.load(swfURL);
                tabCanvas.addChild(matrixLoader);
                tabnavi.addChildAt(tabCanvas,tabnavi.numChildren);
            public var loadedSM:SystemManager;
            private function created(event:FlexEvent):void {
                loadedSM = new SystemManager();
                if (matrixLoader.content != null) {
                    loadedSM = SystemManager(matrixLoader.content);
                    if (loadedSM.application != null) {
                        for(var i:int = 0; i < functionName.length; i++){
                            loadedSM.application[functionName[i].toString()] = paramString[i].toString();
Any help would be greatly appreciated.

Hopefully before you maybe loaded the subapp via
    swfLoader1.source="subapp.swf?foo=1
    swfLoader2.source="subapp.swf?foo=2
And code somewhere in the Application checked parameters.foo and set foo
appropriately:
    <mx:Application initialize="checkFoo()"...
    <mx:Script>
        public var foo:int;
        private function checkFoo():void
            foo = parameters.foo;
Now you just load the module once w/o parameters
    private var modInfo:IModuleInfo = ModuleManager.getModule("module.swf");
And once the module is ready:
    var module1:IMyModuleInterface = modInfo.factory.create();
    module1.foo = 1;
And
    var module2:IMyModuleInterface = modInfo.factory.create();
    module2.foo = 2;

A Bug in mx:TabNavigator ? See small example here

Hi all,
Maybe it's a bug in the TabNavigator component... should I
fill a new bug in the system or is that behaviour well known?
Just compile the code attach to this message.
It's a simple application with a mx:TabNavigator and some
buttons. When you create a new tab, via ActionScript, the 1st tab
ca be automatically selected.
But when you delete all the tabs (either by calling
removeAllChildren(), or by calling subsequently removeChildAt(...)
on every tabs), you wont be able to select the 1st tab, unless you
create a second one, select the new one and select the 1st one
afterward.
Is there any workaround for this?!
I really need to find a fix now, I can't wait another
revision of the Flex framework . . .
Please someone, help me!!!
thanks!!!
P.S. It's not a bug in the attach code, anybody can try this
at home, with the same result...

This is a bug and I just checked the source.
It seems that selectedIndex remains as 0 when you remove all.
When you addChild again, it checks if the index of added children
== selectedIndex and if yes, it do not focus. The patch should
affect removeAllChildren and removeChild, by setting -1 to
selectedIndex when numChidren reaches 0.
Where do I report this bug? It's the second one I found....

Guilherme Blanco

Error in app with TabNavigator loaded with SWFLoader - WebKit browsers

Hiya,
I use a flex app (A) to load another flex app (B) using SWFLoader (both built using Flex Builder 3 sometime ago).
Everything works fine as expected across all (IE, FF, Chrome, Safari) desktop browsers.
However, if I use a TabNavigator within the flex app (B) then when you click on any of the tabs it unloads the flex app (B) and re-starts flex app (A). This behaviour is limited to Webkit based browsers (Chrome & Safari) the rest of the browsers (IE, FF) it works fine.
I wonder if anyone can throw some light on this.
Many thanks
Kind regards,
klem

Resolved:
Replacing the HTML template files with the latest copy from Flash Builder 4.5 seemed to resolve the issue. It appears they have replaced the AC_OETags.js with swfobject.js
Tried to explore upgrading the code to 4.5 but seemed to throw a lot of incompatibilities, created a test/dummy project instead in 4.5 and used the html file created to replace the old html files created by Flex Builder 3.0
Clearly not a very common problem, but hope this saves someone time and effort.
Thanks Harui

Tabnavigator validates when switching pages??

I would like to build a cfform with a tabnavigator and two pages. Each page contains fields with some validation rules. I find that when the user switches pages, any integer, range, or other numeric validation rules are fired immediately. Simple isrequired style rules are not.
It is most annoying, since it looks to the user like there are errors before he has even had a chance to enter data.
<cfform name="myform" height="400" width="400" format="Flash" timeout="600">
<cfformgroup type="tabnavigator" id="tabBar">
<cfformgroup type="page" label="Page 1">
   <cfinput type="text" name="Name" label="Name"
    required="Yes" message="Please enter a name.">
</cfformgroup>
<cfformgroup type="page" label="Page 2">
   <cfinput type="text" name="age" label="Age" value="0"
    validate="range" range="1,1000000" message="This value must be greater than 0.">
</cfformgroup>
</cfformgroup>
</cfform>

Chris,
The DB is Oracle 10g, OS is Windows 2003 Server, The Web Server is in the same machine. The server is Dell 1420 SC Xeon @ 2.8GHx, 512MB RAM. It has not much traffic since we are on the development phase, so i don't think it is a capacity problem.
The problem happens when connecting from the internet as well as from the intranet.
I have not seen the Apache access logs, I will see them and update the thread.
Thanks.

One instance of a component in two TabNavigator children

Hello,
I currently use a TabNavigator composed of two tabs in which
I have two instances of the same component and I was wondering if
it were possible to have a unique instance in those two tabs. Let's
suppose that I have a TextInput in the tab `A' of my TabNavigator,
is it possible to have the same instance of this TextInput in the
`B' tab ?
The component in my problem is a big component that I would
like it to be shared in those two tabs without using something
complicated as addChild() removeChild() on the fly or something too
complex. For now, I have simply a common model to those two
instances but I am mostly worried about memory use, this component
is huge and it would be really cool to have the same instance.
The best would be something like having a reference in the
`B' tab of the instance of the `A' like a pointer but I do not have
enough knowledge in Flex to conceptualize such architecture, so if
anyone has an idea, I'm all hears. Thanks

There's an example of something like that with an Accordion
here:
http://flexdiary.blogspot.com/2008/09/groupingcollection-example-featuring.html
It does use addChild, though (addChild handles removeChild,
so you don't
need to call it separately.

TabNavigator Child Control Problem on Programmatic SelectedIndex Change

I've got a TabNavigator that contains another TabNavigator as
a child control on its second page. On the child TabNavigator
there's a ViewStack and a couple of Accordion controls. On my first
parent tab I've got a Button that, when clicked, programmatically
changes the selectedIndex of the parent TabNavigator to display the
contents of the second tab (which contains the child TabNavigator).
I'm finding that when the index of the TabNavigator is
changed programmatically, all of the controls in the child
TabNavigator are stacked on top of each other and overlapping as
though the Flash player has no clue how to display these child
controls. Once I click through each tab on the child TabNavigator,
they appear intact. If I click the Button to change the tab again,
all of the controls will be jumbled and stacked.
This problem happens 100% of the time. I've changed every
single control in my app to creationPolicy="all" to no avail.
Anybody experienced this or know what to do?

Avoid showing of a canvas in TabNavigator while playing effect?

Hello,
I´m using the great distorsion effect of Alex Uhlmann (part of Tour de Flex) in a TabNavigator with Canvas containers. The effect works fine but while fireing the IndexChangedEvent by pressing a tabsheet for a blink of an eye the target-canvas gets visible before the effect should make it visible which is very annoying.
As you can see in the Code-Snippet
The function playrotate() which is called in the EventHandler only set the right parameters for the CubeRotator method, which create an effectinstance and playing the effect.
public
function ChangeListener(e:IndexChangedEvent):void{oldI = e.oldIndex;
newI = e.newIndex;
playrotate();
private function CubeRotator(DC:String, oldI:int, newI:int):void{
var cr:CubeRotate = newCubeRotate( navtab.getChildAt(oldI) );cr.siblings = [ navtab.getChildAt(newI) ];
if( DC == DistortionConstants.LEFT ){cr.direction = DistortionConstants.LEFT;
else{cr.direction = DistortionConstants.RIGHT;
cr.horizontalLightingLocation = DistortionConstants.LEFT;
cr.duration = 1000;
cr.distortion = 40;
cr.play();
If somebody has an idea how to avoid this behaviour it would be great.
Thanks to everybody answering

Well for what it's worth...
I agree that it's a bad idea using a canvas like that.
Check this out:
http://social.technet.microsoft.com/wiki/contents/articles/29777.wpf-property-list-editing.aspx
Baically, it puts your label and edit controls into a collection of contentontrols presented by a listbox of itemscontrol.
<ListBox HorizontalContentAlignment="Stretch" Background="AliceBlue">
<ListBox.Resources>
<Style TargetType="{x:Type TextBox}">
<Setter Property="HorizontalAlignment" Value="Stretch"/>
</Style>
</ListBox.Resources>
<local:EditRow LabelFor="Label for property One:" >
<TextBox Text="aaaa"/>
</local:EditRow>
<local:EditRow LabelFor="Label for Property Two:">
<TextBox Text="bbbb"/>
</local:EditRow>
<local:EditRow LabelFor="Label for Property Three:">
<DatePicker/>
</local:EditRow>
<local:EditRow LabelFor="Label for Property Four:">
<TextBox Text="dddddd"/>
</local:EditRow>
<local:EditRow LabelFor="Label for Property Five:">
<TextBox Text="eeee"/>
</local:EditRow>
<local:EditRow LabelFor="Label for Property Six:">
<TextBox Text="fffffff"/>
</local:EditRow>
<local:EditRow LabelFor="Label for Property Seven:">
<TextBox Text="ggggg"/>
</local:EditRow>
<local:EditRow LabelFor="Label for Property Eight:">
<TextBox Text="hhhhhhhhhhh"/>
</local:EditRow>
</ListBox>
Listbox has a scrollbar for zero effort and there's no messing about working out all the positioning of each control.
Because editrow is a contentcontrol you can put any old control in it - textbox, passwordbox.... whatever you like.
Hope that helps.

I am using data binding to populate a canvas label in a TabNavigator. The actual number returned is correct, however the non-selected tabs do not show the text that they are set to, because the tab label is only about 20 pixels wide. If I click on the tab that is too narrow, it repaints itself, displaying all text at the proper with. How can I tell the Canvas to keep it's label wide enough to see all the text therein, at all times?   (The canvas.label.length property is read only, and there is no repaint, refresh method)
<mx:TabNavigator x="6" y="77" width="366" height="487">
       <mx:Canvas label="Subjects: {grdSBJs.dataProvider.length}"

TabNavigator - How to change what happens when a user clicks a tab

I am using a TabNavigator in my Flex application and I'd like
to be able to change what happens when a user clicks a tab on the
TabNavigator. I'd like to be able to handle the click on the tab
myself and stop Flex from perfoming it's default actions. Anyone
have a clue how to do this? Any help would be much appreciated!
Mike

Yeah, in the following code, the changeHandler has an effect
but the click effect does not:
<?xml version="1.0"?>
<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml">
<mx:Script>
<![CDATA[
private function clickHandler():void{
accounts.setStyle("fontSize",20);
stocks.setStyle("fontSize",20);
futures.setStyle("fontSize",20);
private function changeHandler():void{
accounts.setStyle("fontSize",7);
stocks.setStyle("fontSize",7);
futures.setStyle("fontSize",7);
]]>
</mx:Script>
<mx:TabNavigator borderStyle="solid"
click="clickHandler()" change="changeHandler()">
<mx:VBox id="accounts" label="Accounts"
width="300"
height="150">
<mx:Label text="Accounts"/>
</mx:VBox>
<mx:VBox id="stocks" label="Stocks"
width="300"
height="150">
<mx:Label text="Stocks"/>
</mx:VBox>
<mx:VBox id="futures" label="Futures"
width="300"
height="150">
<mx:Label text="Futures"/>
</mx:VBox>
</mx:TabNavigator>
</mx:Application>

TabNavigator's tab dynamic visibility handling problem.

Hello All,
I am facing problem in TabNavigator component.
My application has one tabnavigator with 4 tabs. (T1,T2,T3,T4)
Tabs visibility is depend on data which are load in those tabs.
If data is getting Null from database for T2, T2 tab will not displayed. Only other 3 are displayed.
I have tried this....
myTabNavigator.getTabAt(myTabNavigator.getChildIndex(myT2tab)).visible = false;
myTabNavigator.getTabAt(myTabNavigator.getChildIndex(myT2tab)).includeInLayout = false;
but problem is if once tab is hide by above code, will not visible again by setting visibile & includeInLayout property to true.
Anyone else noticed this, have any suggestions?
Thank you.

Hi Tejas S Patel,
I dont see any such kind of problem...I have run a test...it works perfectly fine.
Below is the sample test I have done..
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
<mx:TabNavigator width="103" id="tabone">
<mx:Canvas label="First Canvas" width="100%" height="100%">
   <mx:Label text="First Canvas"/>
</mx:Canvas>
<mx:Canvas label="Second Canvas" width="100%" height="100%">
   <mx:Label text="Second Canvas"/>
</mx:Canvas>
<mx:Canvas label="Third Canvas" width="100%" height="100%">
   <mx:Label text="Third Canvas"/>
</mx:Canvas>
</mx:TabNavigator>
<mx:HBox top="100">
<mx:Button id="btn1" label="HIDE SECOND TAB" click="tabone.getTabAt(1).visible=false;tabone.getTabAt(1).includeInLayout=false;"/>
<mx:Button id="btn2" label="SHOW SECOND TAB" click="tabone.getTabAt(1).visible=true;tabone.getTabAt(1).includeInLayout=true;"/>
</mx:HBox>
</mx:Application>
Thanks,
