Re: [flexcoders] tabnavigator gets messed up

[t...@tamborine.to [flexcoders]]

Thanks.  I'm working on doing that.  I can't really post the code that's 
failing, it's part of an application that's far too big to post, but have built 
a smaller example and can't seem to get it to fail.

I had been setting the selectedChild/index manually and took that out but it 
still fails.  The code only manipulates the tab contents via mx:state settings. 
 So, it's frustrating in that I don't really do anything to manipulate tab 
contents (which would have potential to be my bug).

[flexcoders] tabnavigator gets messed up

[t...@tamborine.to [flexcoders]]

Using FB4 with sdk4.0.

My UI gets user details, then shows a tabbed interface.  Can view any tabs, 
then get new user details.

When the 2nd (and subsequent users) are chosen, the tabbed interface then is 
messed up with the details of the 3rd tab being displayed over the top of the 
details of the default (1st) tab.  It's just a visual representation that looks 
wrong but it's quite messy looking.

Any pointers on what might be causing this?

[flexcoders] TabNavigator

[Richard Rodseth]

Is there an event dispatched by TabNavigator when the *user* switches tabs?

"change" is dispatched when the selected change happens
programmatically (eg. because selectedChild is bound).

RE: [SPAM] Re: [SPAM] Re: [SPAM] [flexcoders] TabNavigator switches to second tab when revealed after a currentState change

[Tracy Spratt]

Sure.  States can be very useful, but I reserve them for more minor changes
the content of a component.  They are very powerful, but messy to code and
understand, compared to a viewstack.  And I do see occasional reports of
strange behaviors interactions with them.

A ViewStack is simply a way to switch between components.  It has no visible
presence of its own.  The children of a ViewStack can be anything (in some
container), including a full TabNavigator.  You can nest ViewStacks as
desired.

 

A side note on TavNavigator;  if you think you will ever want to dynamically
control the visible tabs, say based on user identity/permissions, I advise
TabBar + ViewStack.  To remove hide a tab in a TabNavigator, you have to
manipulate the childen directly.  If you use a TabBar, you can control its
content just by manipulating its dataProvider.  A hidden view will still be
in the ViewStack, but its tab will not be visible, thus the view will be
unavailable.

Tracy,

Thanks very much for responding - I always read your postings with

In my case are you suggesting I put everything into a ViewStack and not use

Subject: [SPAM] [flexcoders] TabNavigator switches to second tab when
revealed after a currentState change

 

  

I've run into a funny problem in a registration application I'm
working on. The base state for this application is a TabNavigator with
three Canvas subelements. On its own, this works fine.

When the application loads, I switch away from the base state to a
screen to let the user login/get their password emailed/add a new
registration. If they want to add a new registration, currentState is
set back to "" to return to the base state - the full data entry form.

The funny part is that when the state changes, the selectedIndex of
the TabNavigator switches from 0 to 1. I've stepped through in the
debugger and before this line the (hidden) TabNavigator has an index
of 0.

this.currentState = ""; // Base state has input form

After this line, the TabNavigator has an index of 1.

If I explicitly reset the selectedIndex back to 0, the TabNavigator is
drawn with elements from the first two "pages" drawn on top of each
other. I can see that the Canvas for index 0 is drawn and the Canvas
for index 1 is drawn on top of that.

I've tried using a ViewStack instead of TabNavigator but, as you would
expect, it makes no difference.

I've been going around in circles for some time here without any
progress - is this problem ringing a bell? I didn't find anything like
it in the archives. I've tried with the 3.2 and 3.5 SDKs but the
behavior is the same in both cases.

I could skip the TabNavigator completely and do everything with
ViewStates but, honestly, I'd rather not. I find it simpler to work
with the TabNavigator in the visual designer. Then again, if it isn't
going to work right it's not really "eaiser" any more.

Thanks in advance for any help or suggestions.

Either write a custom TabNavigator which does it (I can't see any

Just use a Viewstack and TabBar yourself to do the same effect
(TabNavigator doesn't actually add much to just using them
individually).

[flexcoders] TabNavigator changes page (html) title

[ynotob]

I've added a TabNavigator to a flex application.

The application is launched from html that is generated by a java server page 
(main.jsp).  The generated html includes a html page title.  

Up until I added the TabNavigator to the application, the generated html page 
title would display as expected when the flex application is run in the browser.

Now that I've added a TabNavigator, the html page title shows as expected until 
the flex application shows the TabNavigator.  Then the page title changes to 
that of the jsp (main.jsp) along with the full url to main.jsp.

Any idea of how to stop the TabNavigator from changing my page title?

RE: [flexcoders] TabNavigator changing from MXML to actionscript.

[Tracy Spratt]

I typically solve this problem using a TabBar and a ViewStack.  The
ViewStack has all the components and dataProvider for the TabBar is built
according to the permissions, with only the allowed functions.  The
dataProvider items have the index to the corresponding ViewStack child, and
the change event handler sets the ViewStack.selectedIndex with the
item.index value.

Subject: [flexcoders] TabNavigator changing from MXML to actionscript.

 

  

Hi I've an application already mostly written.

Background:

This application uses several custom components that extend or contain
TabNavigators.

A requrirement which I've missed is that if the user doesn't have permission
to view a tab then the tab doesn't appear in the tab navigators.

However tabs still appear even if the child elements they refer to are
invisible.

So I guess that I need to do something like this in my MXML files.  


http://www.adobe.
<http://www.adobe.com/2006/mxml> com/2006/mxml"
xmlns:component="com.example.test.*" CreationComplete="init()">
...
//Normal stuff in here
...
public var tab1:CustomComponent1;
public var tab2:CustomComponent2;
//etc
...

private function init():void
{
  if (Permissions.hasPermission("viewTab1")
  {
tab1 = new CustomComponent1;
...
// Set the properties that are normally specified in MXML
// Add event listeners for all the events normally specified in mxml.
// e.g. tab1.addEventListener(SaveEvent.SAVE, handleSave);
// Do any bindings that are normally associated with the MXML
  }
}

...


Questions:

1.  How do I set up the bindings? I have seen http://livedocs.
<http://livedocs.adobe.com/flex/3/html/help.html?content=databinding_7.html>
adobe.com/flex/3/html/help.html?content=databinding_7.html however this
leaves me worried that binding will occur differently.  I'm particually
worried that I'll get binding events occuring before the component is
initialised which won't (As is normal in mxml) be swallowed by the
framework. I don't even know where I'd put a try block for these errors.
2.  Doing things in this way means that tabs the user has permission for
but hasn't clicked on don't apply for deferred instanceiation. Is there any
way to get this back.  (Normally the tab navigator only instances its
children when the appropiate tab is selected).
3.  Creating the child after CreationComplete doesn't feel right to me.
I guess I could overwrite create children in the above example but not when
my MXML file contains a TabNavigator rather than is a TabNavigator which is
also a situation elsewhere in the application. Is there a better way arround
this?  Creating a ChildDiscriptor object. Does doing things in this way mean
a blank component appears then its contents appear?

Thanks in Advance,
Wes

[flexcoders] TabNavigator creationPolicy

[Richard Rodseth]

I have a TabNavigator with creationPolicy = "auto".
The immediate children are intermediate (superfluous) VBoxes containing the
actual components to be displayed.
Nevertheless actual component A's creationComplete fires even though it's
tab is not the active one.
What's up?

[flexcoders] TabNavigator data provider

[lanekelly5]

I have a ViewStack which I'm controlling with a LinkBar (via the 
dataProvider). I want to have a second TabNavigator (actually the 
google code SuperTabNavigator) controlling this same ViewStack. What I 
can't seem to figure out is how to assign a dataProvider to the 
TabNavigator. Are there any examples that show this? 

Thanks.

RE: [flexcoders] TabNavigator with multiline labels in tabs

[Gregor Kiddie]

I answered the same question last week. The response was...

 

"Yes, but it's convoluted! (Please, if there is an easier way to do
this, 

I'd be interested!) 

TabNavigator has a TabBar, which uses the Tab class to create its 

navigation items. 

You'd have to subclass Tab to create a version which included a button 

with 2 lines of text (That particular piece of info should be easy to 

find these days) 

You then have to subclass TabBar to set navItemFactory to the subclass 

of Tab.

Then subclass TabNavigator to get the tabBar to be your subclassed 

TabBar rather than the standard one. 

It's pretty straightforward, just messy."

Hello everyone,

I'm a longtime Flash developer tackling his first Flex project.

The layout I'm implementing specifies two-line tab labels for the
TabNavigator, which doesn't seem to be supported by Flex per default.
I'm a bit confused as to how I would approach changing the
TabNavigator's tab texfields to multiline. 

I'd be very grateful for any input on this topic.

RE: [flexcoders] TabNavigator - have to click twice on tab to display page

Hi Tracy,

It's really an issue with TabNavigator and we had faced it.
I won't say that I need to click the tab twice, but I need to switch back to
Tab1 and then come back to Tab2 to see the content on my 2nd Tab.

And yes, already tried with creationPolicy='all', but it din't worked.

I have a regular TabNavigator like so:

 




// more tabs go here



Within each tab, at various times in the program, I change the url of
the moduleLoader to load a new module within this container. When I
navigate to another tab, and then go back to this tab, the last loaded
module is displaying.

I would like to have the functionality so that the Label of the Tab is
a hyperlink - that would always load the "top-level" module. In other
words, the tab label will always load a specific module.

How can I make this a hyperlink or a LinkButton when the label
property is actually part of the VBox? Not sure how to do this

Thanks

Using TabNavigator, my app defines 3 tabs:

2. Edit Product Form
3. New Product

As you would expect, the Flow s/b:
A. Select product from list brings it up in tab #2 for edit -and-
B. Select tab #3 brings a new product up in tab #2 for edit.

Flow A is fine - my class handles a ListEvent.ITEM_CLICK, set
SelectProduct to event's selectedItem and then set the selectedIndex
in my tabNavigator to show the edit panel.

Flow B is NOT fine - the class handles a IndexChangedEvent.CHANGE,
sets SelectProduct to new product and then sets the selectedIndex in
TabNav to 1 to show edit panel.

The problem is with Flow B - the correct TabNav panel (product edit)
is displayed but the New Product tab remains selected. My hunch is
the type of event and component redraw flow has something to do with
this.

the help & user group is always appreciated.

Although I could not exactly understand like how you are proceeding with your
application. But as about this error, it is coming because you haven't
initialized something before you are trying to use it.
as in this case, 
this.day.title = "day schedule";
You might haven't initialized "this.day" to something(like new Date() or
whatever it is here) before using it in the above line.

Try to initialize it and then execute your application.

Re: [flexcoders] TabNavigator children

[Paul Andrews]

Why would you have a TabNavigator - something that supports the tabbed 
interface paradigm, showing only one tab at a time, then go ahead and try 
and make it behave like something else?

Why don't you have a TabBar, then manage the displayed pages (containers) 
yourself? You can then dispose of the TabBar and still have the containers 
to work with.

[flexcoders] TabNavigator children

[Daniel]

Hey guys,

Maybe this is easy, but I just can't figure it out! I have a
TabNavigator with a few tabs. At some point at run time I want to
dispose the TabNavigator and draw the containers in its tabs. The
problem is when I get the TabNavigator children and draw them on
screen it draws only one tab (the tab is selected by the time). The
unselected tabs exist, but are not drawn on screen. I've tried to
explicitly setting the position and size of each of them without success.

How can I draw all the tabs?

[flexcoders] TabNavigator and index out of bounds exception

[Mark Bradley]

Greetings,

I am trying to figure out how to get the TabNavigator to create it's  
children so they are accessible after I add the TabNavigator to it's  
parent through addChild().  However, I am getting an index out of  
bounds error because the TabBar children have not been created yet.   
Does anyone know how I can force creation of the TabBar children so I  
can assess them immediately?


Below is an example of the code that show my problem.

Thanks,

-Mark

[flexcoders] TabNavigator & scrollbar space - BUG ?

[bobpardoe1959]

I have a TabNavigator and I add children to it in actionscript. Each
child has its style set to top=2, bottom=2, left=2, right=2.

When displayed the tabnavigator has a 20ish pixel gap on bottom and on
the right of the container area. Left and top are aligned correctly. 

It looks as if it is space reserved for scroll bars.

I have set the horizontalGap and verticalGap styles to be 0. I have
turned off the horizontal and vertical scroll policies, but still it
remains.

Is it me or is the Flex 3 measurement system less robust than Flex2 ?
I seem to be having all sorts of issues relating to the runtime
measurement of HBox and VBox components when sized by percent or styles.

Is anyone able explain what might be going on ?

Thanks

BOb

 I have a TabNavigator with 4 tabs in it. Each tab has got a HBox with

 My tabs are right aligned and I want to be able to utilize the empty

I have a TabNavigator component that I completely reset the tabs
dynamically with the following code:

tabNav.removeAllChi ldren();
for each (var container:Container in myList )
{
tabNav.addChild( container)
}
tabNav.selectedInde x = 0;

So this successfully removes the existing tabs, then loops though my
ArrayCollection and adds a new set of tabs. It also shows the
contents of tabNav[0], but the tab that displays as selected is
whatever was currently selected. So if I originally displayed the
tabnav and clicked the 3rd tab, then clicked the button completely
outside of the tabnav that causes it to redisplay, it will correct
show the contents of tabnav[0], but visually it looks like the 3rd tab
is still selected.

I also tried tabNav.validateNow( ) and it doesn't work. To test I
added a button completely outside of the tabnav with
click="tabnav. selectedIndex= 0", works great.

So what am I not doing?

Hi all,

I have (after days of troubleshooting) figured out the the use of a
tabnavigator component in my applications is causing any further use of
a tween (even the opening of a combobox) to crash flash player and the
browser.

I can use the tweens successfully up until the point that i click on
another tab in the tabnavigator then the player grinds to a halt and
becomes unresponsive.

I have created an entirely separate test application and have been
unable to replicate the results. Does anyone have any advice on where to
look (in my code) or have experienced something similar?

Both apps are Flex 2, Cairngorm 2.2.

Many thanks for any help or direction

TitleWindow closes instead of changing state. Silently, no exceptions thrown.

Re: [flexcoders] TabNavigator+States=Crash

[tpokrajcic]

I generally had a lot of pain with states during past few weeks...
This is a very simple example that doesn't work, and I have many others.
In some cases something just crashes (like here), sometimes state changes
don't apply everywhere and sometimes component coordinates get messed up (it
seems to me as coordinate root is not referenced to parent container but to
grandparent container).

But in all my cases there's one common denominator - TabNavigator.

My bad luck is that my app has bunch of this TabbedWindows, and if there are
more than 2 tabs I'm sweating...

Re: [flexcoders] TabNavigator+States=Crash

[Jerome Clarke]

I think what he's saying is...

you press the button "Open window" and then press the button "Change state"
and the window closes straight away...

However if you press the "Open window" button and then click to Tab 2 and
then Tab 3 and then press the "Change state" button... then the label in
each tab changes to a text input field...

the bug is it's closes the flex window after you press the "Change state"
button without clicking through the tabs ( I had to select 2 different tabs
before the "Change state" button worked correctly )

I made a simple example of TitleWindow with TabNavigator and 2 states.
Please check it out (source view available) at:

Window crashes after pressing button for state change. But if you walk a bit
over tabs (click Tab2 and Tab3) window changes state.

[flexcoders] TabNavigator and States problem

[tpokrajcic]

I have a TitleWindow and a TabNavigator inside with several tabs based
on Canvas.
There are two states - "Base State" and "Edit". TitleWindow goes to
"Edit" state upon click on "Edit" button.

Now a problem:
After clicking on a button, state of current tab changes to Edit, but
when I click other tabs, they're in Base State. 
Actually, after switching tabs I can see in a blink of an eye that
other tab somehow changed state from Edit back to Base State, but when
I place breakpoints in UIComponent state handling functions I can't
catch any state changing there...
And more strange is that the first tab always has a correct state, no
matter on what tab I was when clicking button.
Anyone experienced something like this?

[flexcoders] TabNavigator : Is there a way to set corner Radius to only bottom corners?

[thebeginnersmind]

Is there a way to set cornerRadius of Tab Navigator to only bottom left and 
bottom right 
corners ( and not 4 of them)  ?

 (The below code in css sets cornerRadius to all 4 corners.)

TabNavigator {

cornerRadius: 10;

}

Thanks!!

Re: [flexcoders] TabNavigator no child selected

[Rico Leuthold]

I tried that. The problem is the tabBar (where I have to change the  
border color as well) which is not acessible from the TabNavigator.
The only way I found so far is to change the styleName property of  
the TabNavigator, but this is an extremly slow action (around two  
seconds).

Re: [flexcoders] TabNavigator with Local tag ..

[Abdul Qabiz]

Hi,

While building RIA using Flex or AJAX, we think in terms of views instead of
pages. We can consider each tab is a different view, each view could be a
separate (or same) component/module...

We can create views either by using inline tags or using components
(actionscript or mxml).

f.ex:

## Example.mxml - A MXML component

http://www.adobe.com/2006/mxml";>



## YourApp.mxml

http://www.adobe.com/2006/mxml"; xmlns:local="*">


   
  




Note the xmlns:local="*", that allows inclusion of mxml components in your
application under some namespace.

In my app am using the TabNavigator control for displaying Tabs. When I
click on click on each tab I've to open an mxml page with in a tab.

for this am using like

Since am using Local tag, am getting a error like "Display Child Object

Instead of using local tag is there any other alternative for this to achive

RE: [flexcoders] TabNavigator and includeInlayout

[Alex Harui]

includeInLayout is a flag on UIComponent and therefore Canvas and just
about everything as to whether its parent container should include it in
its layout algorithm, which is why only HBox, VBox, etc will actuall
examine the flag on its children.

 

Navigators do not examine this flag, and use visibility to hide the
unselected child, so there's no easy way to hide things from the
navigators we ship.  SuperTabNavigator does, I believe, so check it out.

Re: [flexcoders] TabNavigator/ToggleButtonBar Style conflict

[Derek Vadneau]

Thank you for the workaround, it will work great for my project.

Now, I can maybe understand that it's perhaps not a bug but it definitely is
a shortcoming of the style system and docs.

There is no mention of Tab in the docs. I had to go look for the class in
the SDK just to know how you got that.

Also, other than searching through the component code, the only method given
for setting the styles on the components is what I gave. In fact I got that
from the Adobe style explorer app.

And if I had a TabBar component in my project (I don't but bare with me) it
would take on the style I set with Tab, which I would expect, but not
necessarily want.

When I explicitly set a style for a component I expect that it takes on that
style. I understand what you mean by TypeSelectors and inheritance, but that
just means the style system (or code implementing it) might be flawed. When
I set a style for ToggleButtonBar, I would expect ALL instances of
ToggleButtonBar to take on that style. However, in the case of the
TabNavigator (and any other component that contains other components) when
there is a way to explicitly affect a child instance within, that should be
honoured.

Going back to my code, I would expect that the text in each TabNavigator tab
might be red (because of the ToggleButtonBar styles), but they aren't. Only
the first and last are. And I would expect that the cornerRadius set by the
TabNavigator style be honoured. If I set the cornerRadius as you mention in
mytoggleButtonBarFirstButtonStyle, I would expect the TabNavigator style to
override that style. Why? Because that style was explicitly set for the
TabNavigator's children.

A simplified example, but just to show where my head is at: Take an HTML
page with CSS. If I have a list item of an unordered list and specify a
style for li to be color:#FF and font-weight:bold, the text would be red
and bold. If I set a particular list item to use a class style where the
color is #FF, that one list item would be blue and bold. That would be
my expectation anyhow.

Hopefully you get my meaning.

Thanks for you time!

Solves your Problem. This is not a bug.

Since you are setting a firstButtonStyleName on an actual selector,
TabNavigator will not pick it up since it is undefined to begin with and now
defined on the super class TypeSelector of TabBar.

If you set

.mytoggleButtonBarFirstButtonStyle {color: #FF;cornerRadius: 0;}

You will see that changes the radius of the first tab button.

I've run into a problem when trying to set the selectedIndex property
on a TabNavigator. The TabNavigator is set in mxml, however I am
adding and removing children with AS3 at runtime depending on what
node the user clicks in a Tree control (hope that makes sense). The
children are doing what they are supposed to (i.e. attaching and
removing, and getting initialised with whatever data I pass to them).
But when the selectedIndex is, say, 3 and then the user clicks a tree
node forcing the TabNavigator to remove and reload children, I am
trying to reset the selectedIndex property back to 0 (to show the
first tab) - this part works, that tabnavigator shows the right tab,
but the tab button that appears selected is still the old property (3
in this scenario). 

So is this a display problem or the way that I am adding/removing
children? I have tried invalidateDisplayList() and callLater, but
nothing seems to help. Hope someone has some insight...

Cheers.

children?  I have tried invalidateDisplayList() and callLater, but
nothing seems to help.  Hope someone has some insight...

[flexcoders] TabNavigator and Text

[Matt]

I'm dynamically creating content with ActionScript and I create a
TabNavigator (set creationPolicy to 'all') and then add Boxes with
Text HTML content in each. My problem is that the first time I go to
each tab it takes a minute for the content to render but after that it
works fine. Is there any way I can tell it to pre-render so it looks
correct the first time it's selected?

RE: [flexcoders] TabNavigator focus issues

[Alex Harui]

Tabs that haven't been looked at don't have their children created yet
for performance reasons.  I think many folks use a pull-down strategy.
You keep a central notion of what the current item is and each view
widget binds to it.

Subject: [flexcoders] TabNavigator focus issues



I'm having the following issue. I have a layout of data seperated into 
4 tabs. The first three hold different sections of data for the same 
product. All product data is recieved from the CFC and stored as an 
ArrayCollection. The fourth tab contains a TileList that is populated 
from that ArrayCollection. When an item is selected on tab 4, I want 
it to update the fields on the other 3 tabs.

When I had everything on one tab, this was working fine. After 
seperating it into 3 tabs, I started getting errors. I started 
removing set statements from the function and was able to discover that 
if I only tried to set the text value of fields in first tab in the 
stack, it worked fine. If I changed the order of the stack and tried 
to update those fields instead, they would update fine. 

So what am I missing? how do I get it to update the fields in tabs 
other than the top one in the stack?

Thanks.

[flexcoders] TabNavigator & Filtering with Comparator class

[ajudah987]

I am using a tabnavigator with a Canvas and then a TileList in it.
I have a horizontal slider similiar to the Flex store to filter 
products based upon price. 

My challenge is that when i adjust the slider the Comparator class 
adjusts the alpha of just the items visible in the tilelist. It does 
not filter the items when u scroll down the list.

As well it filters all visible items except the first item.

Does anyone have any ideas on how to address this?

Thanks in advance

[flexcoders] TabNavigator - reset to the first tab

[maticpel]

Hi,
how can I set the tabIndex to 0, if the dataProvider changes ?

Example: http://www.ubuntuusers.de/paste/8035/

If you click on the second tab and then button "5 Seiten" you see the
content of the first tab but the second tab is always selected. 

Thanks,
Flayoo 

[flexcoders] TabNavigator - reset to the first tab

[Flayoo]

Hi,
how can I set the tabIndex to 0, if the dataProvider changes ?








I tried:

public function init ():void
{
tab.selectedIndex = 0
Log.Debug("Index "+ tab.selectedIndex);
}

But this doesn´t work because "tab.selectedIndex" is always "0"

Thanks,
Flayoo

[flexcoders] TabNavigator Tab BackgroundImage

[cgiamett2]

I have been doing a lot of looking around and cannot come across how to 
add a BackgroundImage to tabs in a TabNavigator.

I have seen buttons added, etc. Is there a simple way to just add an 
image to tabs?

Re: [flexcoders] TabNavigator and SWFLoaders problem

[Angus Johnson]

Hi Nick,

I don't if this will help you but one thing that I found with loaded swf's
is that if you explicitly set height and width on the loader and then
attempt to apply percentWidth or percentHeight it will fail to render.

If i set height=100, width=100 then percentWidth=50 and percentHeight=50 I
end up with height=0 and width=100... if you follow that :). Something a bit
odd there I think but I don't fully understand how things are sized.

So maybe your tabNavigator is applying percent measurements to a loader
where you have explicit width / height???

You should be able to see these properties in debug.

  Hi all,

I've been lurking on this list for a few weeks but I've now run into
a problem and need some help myself...

My application's main screen consists of a number of windows, each of
which is a Flex application in its own right. The layout of the main
screen is configurable from an external file which I parse at runtime
and create the corresponding controls/sub-applications using
Actionscript. Each sub-applications is loaded in a SWFLoaders which
has been sized appropriately and added to the configured container.
Once the screen is built I then tell all the SWFLoaders to load their
content.

This has all been working fine until now. What I want to do is have
a TabNavigator on the main screen with several tabs - each tab
containing a sub-application so that the user can flip between them.
What I am doing is creating a SWFLoader on each tab (within a canvas)
and setting their widths and heights to 100% (to fill the tab
whatever its size may be).

The sub-application on the first tab (i.e. the one visible at
startup) is fine - it fills the tab as planned. However, the sub-
applications on the subsequent tabs do not appear - UNLESS their
widths and heights are set explicitly (e.g. width="200"
height="100"). However this breaks my ability to change the size of
the tabs and still have the contents fill them. Nothing changes if I
set the TabNavigator or canvas creationPolicy to "all" either.

Any ideas anyone? Is this a bug?

I cannot post my entire application as it is getting pretty huge :-)
However I have created an example application which shows a similar
problem:


http://www.adobe.com/2006/mxml";
layout="absolute" applicationComplete="doStuff()">


















This application creates a TabNavigator with 3 tabs - all of which
contain a SWFLoader which loads BlueBox.swf. BlueBox.swf is simply
an empty application with a blue border and background so I can see
how large it is once loaded (see below).

Tabs 1 and 3 are identical - i.e. they both contain a SWFLoader sized
to 100%. However the one on tab 3 does not get sized/loaded
properly. The SWFLoader on tab 2 is very similar but its SWFLoader
uses explicit widths and heights (which seem to work).

Here is my BlueBox.swf:


http://www.adobe.com/2006/mxml";
layout="absolute" backgroundGradientColors="[#ff, #ff]"
borderColor="#ff" borderStyle="solid" borderThickness="2">


Thanks for your help (if you've managed to stay awake through all
that!)

Re: [flexcoders] tabnavigator transitions

[Yiðit Boyar]

what i meant was choosing the effect to be played @ runtime, according to user 
commands.
in other words; i want to control played transitions... assume tab2 is opened; 
when the user clicks tab3, 
diffrent (predifined) transition effects will be played. but when the user 
cliks tab4 from tab2, standart transition effect will be played.

so to conclude; i need a function; that is triggered in tabchange and it will 
decide which container will use which transition effect..

so 2 problems: 
-a trigger event (i already have, which i use to call inner containers 
functions)
-dynamically setting the transition effect of a container.. (this also seems 
available but i could not tried yet)

Choose the Transition effect?  Do you mean use a different effect 
than the fade, or change the effect at runtime?  If you want something other 
than fade, you can use any of the available effect, Zoom, Rotate, Move, ect...  
If you are wondering if you can change it during runtime, I believe it's 
possible, although I haven't done it.  It shouldn't be much more than setting 
the showEffect or hideEffect during runtime.  Sorry if I misunderstood your 
question, but hopefully that is what you were looking for.

Yigit,



You can try to use the hide and show effects on the child containers of the 
TabNavigator. The TabNavigator will play these effects when it changes. Here is 
some small pseudo code... You can use any of the Flex events in place of the 
fade affect. Note this was coded in Outlook, so not sure if it compiles, just 
wanted to throw something together for you.
