Re: [flexcoders] TabNavigator - Hiding Tabs

Hi Ali,

I'll give it a try tonight.

One of the other difficulties I was having was this:

I wanted to Keep a tab's state when a view is switched.

For example, I have something like:

tabNavigator
---pets
-----dogs
-----cats

---programmers
-----java
-----actionscript
-----php

/tabNavigator

I am currently hiding tabs for dogs, cats, actionscript, etc (all the children). Ideally, I'd like to keep the state of the parent tab up. Perhaps I could wrap those views in a Canvas with an ID, but I wouldn't know how to specify that child within the modelLocator.

Hi Dave,

Have you tried using the resize handler of the TabNavigator, and resizing the tabs at that poing? I'd probably wrap this inside a custom TabNavigator component.

Cheers,

Ali

Hi Alistair,

I'm using Cairngorm .99 and have added about 10 mappings to my ModelLocator.

Of those 10, 5 are views that need 'tab-ability' and 5 should be hidden.

I used the method below, hiding the tab and setting visibility to false. This works, initially.

However, when the stage is resized, the tabnavigator recalculates and repositions the tabs, including the tabs with the width set to 0.

Is there another workaround?
Is there a way to add a Stage.onResize listener in Flex to reset specific tabs within the tabBar to a width of 0?

Hi Alex,

Try this - I've made the tab visible and also set its width to 0, to force
subsequent tabs to move along to consume the space. tabBar is a private
property of TabNavigator, so I've had to trick the compiler into letting us
access it.

                {
                        var secondTab = tn["tabBar"].getChildAt( 1 );

                        secondTab.visible = false;
                        secondTab.width = 0;
                }
        ]]>

Subject: [flexcoders] TabNavigator - Hiding Tabs

I am trying to hide certain tabs from a Tab Navigator based on some
criteria. If I follow this approach: tabnav[0].visible = false; the actual
Tab is still visible but the children within that tab are invisible.

How can I hide the tab button itself?

Thanks,
Alex
