Re: [g-a-devel]Accessibility for "Stock Ticker Applet "

["Padraig O'Briain" <Padraig Obriain Sun COM>]

I have managed to run the gtik applet in my panel but it does not do anything 
useful so my comments will be superficial.

Can the applet be used with just the keyboard, i.e without using the mouse?

What widgets in the applet can receive focus?

Concerning implementing AtkText for scrolling items, what is so wrong about 
presenting all the text. The only problem I can see is that it is difficult to 
determine exactly what text is being displayed at a specified time but I would 
expect that the consumer of the AtkText interface is interested in all the text.
