+ + + + + Overview + + + + Cally (Clutter Accessibility Implementation Library) is the + Clutter implementation of the ATK interfaces. You can see as the + Clutter equivalent of GAIL, which provides accessibility support + for GTK+ and other GNOME related libraries. + + This implementation expose Clutter actors to accessibility + tools like Orca. This allows not only writing accessible user + interfaces, but also allows testing and verification frameworks + based on accessibility technologies to inspect and test a Clutter + scene graph. + + This reference manual defines the different APIs defined in + Cally. Anyway take into account that the most common use of case + Cally is transparent to the user, as the different accessibility + tools are intended to use the abstract ATK interfaces, and *not + directly* Cally, so this tools can communicate with applications + using different toolkits, like GTK+, Java, Clutter, etc. + + The purpose of this reference is allow to extend Cally + functionality in any Clutter-based widget toolkit. Clutter is more + low-level that other toolkits like GTK+, and some toolkits have + started to appear based on Clutter: MX, Shell Toolkit, Candies, + Glitter, etc. This means that it is really likely that these + libraries will require extra accessibility support. + + GAIL used a different approach, being a almost-pure-opaque + implementation of the ATK interfaces. So you can't extend it + directly. You need to use GObject and ATK mechanisms, like + run-time anonymous inheritance, to extend it. Although valid to + some custom cases, it showed to be really problematic and hacky in + wider approaches, like HAIL(Hildon Accessibility Implementation + Library). As explained, Clutter is more likely to be extended, so + these issues would arise sooner. + + Part of the accessibility support is implemented on Clutter, + like the initialization code, and the method to obtain the + accessibility object for each Clutter object. In the same way, to + make it easier, and to allow access to Clutter object private + data, it would be really likely that the accessibility support + would be implemented directly on some Clutter objects + + Check the next clutter methods for more information: + + + clutter_actor_get_accessible() + Virtual method to obtain the accessibility object of a + clutter actor + + + clutter_get_accessibility_enabled() + Method to check if accessibility is enabled. + + + + + + diff --git a/doc/reference/clutter/running-clutter.xml b/doc/reference/clutter/running-clutter.xml index 64e97ec..7e0a646 100644 --- a/doc/reference/clutter/running-clutter.xml +++ b/doc/reference/clutter/running-clutter.xml @@ -137,6 +137,10 @@ Unsets FLAGS from the COGL debugging flags. + + --clutter-enable-accessibility + Enables accessibility support. + The X11 backends also have the following command line
