Open a new Browser tab from Tab navigator Content
The function is not being called. what should I do to get this to work?
protected function truckingMenu_clickHandler(event:MouseEvent):void
{
var connection_request:URLRequest;
connection_request = new URLRequest("file:///D:/Trucking.html");
connection_request.method = URLRequestMethod.POST; // setting method type
navigateToURL(connection_request); // this is standard function.
}
<mx:TabNavigator width="96%" height="90%" borderVisible="false"
horizontalAlign="center" fontSize="12">
<s:NavigatorContent id="truckingMenu" label="Trucking"
click="truckingMenu_clickHandler(event)" >
</s:NavigatorContent>

I'm sorry I wasn't clear, I meant a single simple file that illustrates
the problem. It may be better to put this on PasteBin or similar.
I assume when you right click the running .swf that 'Debug' appears in
the menu and you can select it ?
If so, please confirm you can at least get a breakpoint from a basic
creationComplete or childAdd event of the TabNavigator.
I ask because I always rule out the obvious first.
I'm always having an automatic security update nuke my debug Player,
which eventually reminds me to update it :-)
Assuming that works, I expect that listening for clicks on the child
doesn't work the way you expect because you are clicking the content,
not the element. I have a memory of this tripping me up before, which is
why I suggested using an event on the TabNavigator itself, like
childIndexChange, for instance.

If you look at my original question, you can see I provided the code. I am
using FB 4.5 on a Windows 7 computer. The browser is Firefox if not the
latest version, fairly close since I installed it a month ago.

Hey, the change event in the TabNavigator does fire. So I might have an

Thank You. I take it just because an event is available does not mean it
actually works. Do you know of a way that I can tell when an event is
available that it would work or not so I dont have to ask this type of
question any longer?

Re: Open a new Browser tab from Tab navigator Content
Posted by CodeGirl <Mi...@yahoo.com>.
Its probably a FB issue. I was trying to trigger off the Navigator Content.
I am now triggering off the tabNavigator Change event. What I was
trying to do is open a new window with a new set of tabs for a different
group of screens. Right now, I am using the change event and the newIndex
property. Though if I ever add a new tab and forget this, the desired
behavior for that tab will mess up. But at first glance, I didnt see
anything that was better. Such as newItem so I could compare id names.
But at least I found something that works.

Check the docs or source if available. There is no click event listed in the Events section of the NavigatorContent docs.
I think this is an exception though, I use Flash Builder and don’t remember having seen this problem before.
Not sure if this is a FB issue or some other problem.
I’m not clear on what you are trying to do. Does the Change event not work for you? Are you not trying to detect that a certain tab was activated?
This works fine for me, ie. I get an Alert window on every tab change:
<?xml version="1.0" encoding="utf-8"?>

connection_request.method = URLRequestMethod.POST; // setting method type

}

As far as I know, NavigatorContent isn’t clickable. It is just a non-visible wrapper that allows Spark components to work within the MX TabNavigator.
If you want your function to be called when the user activates that tab in the TabNavigator, use the events on the TabNavigator object as suggested by Tom, such as the Change event that is dispatched when a new tab is activated.

Sorry you feel that way, but as you say I did think that - your message
carried no indication of what you had already tried, and I've no idea on
your level of experience with Flex.
If you are unable to get even a a simple event like childAdded to pause
in the debugger, please clarify exactly what you have tried, with full
(not working) example code so that we can help.
We'll also need details about what Flash version, web browser or AIR
runtime you are using, as well as how exactly you are trying to debug
(Flash Builder ? Command line ?)
With out a full set of details, you are not going to get a very useful
response, and we'll both waste time asking questions back and forth
trying to see if you are using the wrong event, or there is something
with up with how you are debugging.

I think you are completely in appropriate. I am guessing you think I didnt
already try to find the answer before I asked the question. Your first
response was asking if I knew how to debug or not. The second made the
assumption that I hadnt already tried to find a different solution. I was
trying to be polite. But this last one was in excusable.

Have you tried alternative events, maybe even those on the TabNavigator
itself ?

The first indication it didnt work was that a new tab didnt open. Then yes,
I placed a break point and it didnt stop.

So you set a breakpoint on the first line, and it doesn't stop ?
You've tried replacing the body with a simple Alert.show() and it
doesn't appear ?
