Re: [g-a-devel]Accessibility for GnomeCharmap

[Marc Mulcahy <marc mulcahy sun com>]

If we take Padraig's approach, and make an AtkObject for GnomeStatusBar 
with a role of ATK_ROLE_STATUSBAR then we wouldn't necesssarily have to add 
tooltips to all the buttons.   We could rely on the assistive technology to 
do the right thing and read status bar changes.  As Padraig suggests, the 
text is available now without any modifications, but it is not obvious to 
an assistive technology that the text is contained in a statusbar.
