Re: [Lubuntu-desktop] Fwd: Lubuntu and Accessibility
Thanks. I'll keep a copy of this notes, It will be useful when the work on accessibility will start :) Regards, Julien Lavergne Le Tuesday 24 May 2011 à 23:58 +0100, Phill Whiteside a écrit : -- Forwarded message -- From: Rob Whyte fu...@thefudge.net Date: Tue, May 24, 2011 at 8:24 AM Subject: Re: Lubuntu and Accessibility To: Phill Whiteside phi...@ubuntu.com Hi guys, in my own efforts to get orca better with LXDE I conversed with Klaus Knopper the author of Knoppix.

Re: [Lubuntu-desktop] Fwd: Lubuntu and Accessibility
For the panel, Brian Cameron has a good idea. He suggested that we can use a different UI for orca. That means, replacing all buttons in the bar with standard GtkButton widget rather than some hand-made ones. This looks ugly, but will have much better usability. If accessibility mode is on, we use standard GtkButton with text label rather than current ones with images on them.

Hi I like that approach, Plus as I'm totally blind, I don't care about the graphics and that's just resources being used for no reason for some buttons.

An alternative is to make the existing buttons accessible, by adding calls to atk to properly identify and label the buttons. This reduces the amount of divergence and makes it easier for you to maintain, as you don't have to maintain a set of buttons using 2 different ways of rendering etc. Luke -- Ubuntu-accessibility mailing list Ubuntu-accessibility@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-accessibility
