Accessibility/Comparisons

Gecko's Accessibility Interfaces are Cross-Platform

At the heart of Gecko's accessibility architecture are the cross-platform nsIAccessibility interfaces. The goal is that these be the sum of all accessible toolkits on the various platforms.

Different implementation for each platform

However, in the real world, operating systems work differently. A developer that needs to make an application accessible has to do it in different ways, depending on the OS of choice.

Comparing the accessibility architectures

When implementating support for a new system in our cross-platform accessibility architecture, we need to make sure it fits up to the standard of the other implementations.

One way to do this, is try to find out their pecularities using comparison tables. Below you'll find such comparisons, showing what each accessibility implementation does and does not support.

• Comparison of roles
• Comparison of states
• Comparison of events/notifications
