If you are just using a Tab button,
opps, I meant Tab Bar. Both ways are correct in component development sense.
But you would choose either or based on the factors of... am I going to be
using a tab navigator?
anyway, both will work with some fine tunning.

Hi,
All you need to do is this;
1. Subclass TabNavigator;
2. create
-> protected var addButton:Button
3. In createChildren() ovveride;
addButton = new Button();
addButton.styleName = this;
addButton.label = "Add";
addButton.addEventListener(MouseEvent.CLICK, addButton_clickHandler);
rawChildren.addChild(addButton);
4. In the updateDisplayList() override
position the addButtonl; something like..
addButton.move(unscaledWidth - rightPadding -
addButton.getMeasuredOrExplicitWidth(), paddingTop);
addButton.setActualSize(addButton.getMeasuredOrExplicitWidth
addButton.getMeasuredOrExplicitHeight());
Your needs may vary.
5. create the handler
private function addButton_clickHandler(event:MouseEvent):void
{
dispatchEvent(new Event("addButtonClick"));
}
Vola, you now have a button that you could even skin and...
It gives you a custom event to listen for outside of the TabNavigator.
If you are just using a Tab button, it is the smae procedure although
there might be depth issues that you will have to address.
Peace, Mike
