TabNavigator tabs alpha
Hello!
How do I set the alpha for the Tabs in a TabNavigator that are not selected, please?
Hmm... so for say TabNavigator tas and/or buttons, if I don't want them to inherit the background color of the parent (by having alpha) I MUST implement custom skins?
There is no CSS selector to chage this?
background-alpha:1 does not solve this sadly.

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?

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)

TabNavigator Tab content refresh
Hi,
I have a TabNavigator with let's say two Tabs - TabA and TabB along with its contents. Both tab contents read and change xml on which their both contents depends. If i click TabA, then on TabB in which content i modify xml and then return to TabA which also depends on that xml but change won't be reflected like TabA content is not refreshed :/ So i am not sure how to handle that, how can i accomplish that Tab content refreshes every time i click on Tab?
Thanks,

TabNavigator tab selection event
I've been trying to trigger an event when i click on the tab in a tabnavigator.
The problem is that if i try to use the "change" event, the events for components inside the tab navigator are being fired and thats causing me problems. Could you suggest an alternative to "change" with a specific event that would enable me to fire a specific function only when i click on the tabs?
I know the question is trivial but I couldnt find an answer anywhere.
Thanks in advance<s:VGroup>

TabNavigator tabs not initializing
I am using a tabnavigator, but when I use the application, if
I access components on tabs that the user has not yet selected, I
get errors as if those components were null. If I click on all of
the tabs before doing anything, the program works fine. How can I
force the other tabs to initialize properly so that I avoid the
null errors?
ThanksAdobe Flex lazy loads components when it needs them,
try to Bind you variables to your components if you can.
if not add this to your tab navigator:
<mx:TabNavigator creationPolicy="all" ...............

TabNavigator: Tabs have a dropdown list
I want to create a TabNavigator, in which some of the tabs
contain a dropdown list. When those tabs are clicked, the
dropdown list is displayed and you can select one of the
items in the list. The display will change after the selection.
Is there is simple way to do it within TabNavigator?I don't think you want a TabNavigator then. The tabs in a
TabNavigator are used to, on click, switch through a view stack for
instance.
Seems like you could do what you wanted without a
TabNavigator at all. Place some labels at the top (styled like tabs
if you so desire), on click use an Effect to show a canvas sized as
your desired subnav (wipe down from the label you clicked, move it
via animation, bounce, etc). -
Module loaded from TabNavigator tab displays blank screen
I have an application which is using the TabNavigator to manage the active view content. The tabs are backed by individual VBox's which contain the
mx:ModuleLoader commands to load the module swf's. The application runs and the appropriate tabs are displayed.
When clicking on the various tabs, I know that the Ready ModuleEvent is getting fired and that the module projects default mxml class is being loaded and executed. However, the view content of the module is never displayed in the browser.
The following is a clip from the code block:
<mx:TabNavigator id="mainMenuTabBar" width="100%" height="100%" creationPolicy="auto" tabStyleName="tab">
<mx:VBox id="moduleOneTab" label="ModuleOne" creationPolicy="auto" width="100%" height="100%">

preinitialize="testLoader.applicationDomain=ApplicationDomain.currentDomain" />

<mx:ModuleLoader id="testLoader" url="testModuleOne.swf"
preinitialize="testLoader.applicationDomain=ApplicationDomain.currentDomain" />
</mx:VBox>
</mx:TabNavigator>
Any suggestions would be greatly appreciated.

Tabnavigator tab shift on rollover
Wondering if anyone has any ideas on why on a TabNavigator
component, when I roll over the first tab (which is selected by
default, fonts embedded, creationPolicy='all') there's a slight
size shift in the tab and, after that, all is well. Does anything
come to mind?

Is your rollover font different at all (for instance, bold)
from your
ordinary font? -
Changing hover color for TabNavigator tabs
I was able to change the background color of selected tab to
Navy and the others to Medium Blue. The foreground color is set to
White. The default color for the hover seems to be black, so when I
pass over the selected tab you can not read the text.
How do you change the hover color?Try setting the textRollOverColor of your selected tab style.

I have been struggling for a while with trying to change the color of a tab, after it's been displayed. Some background is that i have a multi tab window. If something happens in one of the windows, I want to bring attention to that tab and color the tab red.
I am dynamically adding the tabs to the tab navigator from database table. I read them in with their data and when I have them all I build up the tab navigator. My TabObject is really a Canvas that I have extended.
private function AddTabsToTabNavigator():void
var lIsFirst:Boolean = true;
for each ( var lTab:TabHandler in mTabDictionary )
// Create our Frame Canvas that we are going to add to the Tab Navigator
var lTabItem:TabObject = new TabObject();
lTabItem.name = lTab.GetTabName();
lTabItem.SetRefreshTime(lTab.GetTabRefreshInterval());
//lTabItem.setStyle( "tabStyleName", "tabStyleGreen" );
//lTabItem.styleName = Constants.TAB_STYLE_GREEN;
//TAB_NAVIGATOR.invalidateDisplayList();
lTabItem.setStyle( "backgroundColor", "green");
TAB_NAVIGATOR.addChild( lTabItem );
I've tried a number of things comented out here. I have a CSS and I can set the initial color of the tab no problem.

Hi all, I have a Tabnavigator with 5 tabs, each of which has charts of one sort or another. Since migrating to FB4 I get a problem where if the contents of one tab change, suddenly the content of all of them is displayed at the same time which looks absolutely awful. By clicking on each of the tabs the problem is gradually removed. I saw someone else reported this problem on stackoverflow.com:

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?

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?
