Re: [flexcoders] Closable Panel? (flex2)

[Jason Y. Kwong]

I ran into a similar situation a while ago where I needed to add stuff to the panel's title bar.  While it's possible to use a Canvas to lay stuff on top of a Panel, this doesn't work if you're trying to create a re-useable custom Panel because the resulting component is a subclass of Canvas, not Panel.  If you try to use it in MXML, you'll be adding children to the enclosing Canvas, which is not what you want.
What I ended up doing was subclassing Panel via AS only and then overriding the createChildren() and updateDisplayList() methods.  It just so happened that the Panel's title bar object, titleBar, was declared public so I was able to accessi it and add children to it.  I've no idea if this still works in the Beta as I've yet to try it.
Is there a better solution?On 2/3/06, Alex Uhlmann <[EMAIL PROTECTED]> wrote:

(flex2)
I know that mx.controls.Panel contains a 'closeButton' which is 
utilised in the subclass TitleWindow. I really would like to have this close 
button on panels as well, so i guess i have to subclass Panel to achieve this. 
However, I have no clue of how to make this button visible and position it in 
the title area. Could anybody please help with this? --gunnar
