Mozilla accessibility architecture
shtmltablecellaccessible(domnode, weakpresshell); special exception: traversal overloading in some cases the necessary accessible children are not in the dom subtree for a node. this is the case for: nshtmlimageaccessible: in msaa an image accessible can have accessible children if it has an image map. the children are the image map areas, which are in a different part of the dom tree. nshtmlcomboboxaccessible: an html combo box doesn't have a dom node or anonymous content for its s textfield, button or list. in the future xbl form controls may be used, in which case there will be dom content for these sub-parts, and we will not need to override the traversal methods. that is why we don't need to override these traversal methods for nsxulcomboboxaccessible (<menulist>). nsouterdocaccessible...
...d by the tree itself to get the text for each row, column in the tree. in all of these accessible implementations we override nsiaccessible::getaccchildcount(), ::getaccfirstchild() and ::getacclastchild(). in this way we avoid the normal nsaccessibletreewalker traversal methods and create whatever child accessibles we want. when there is no dom node for each accessible, as is the case for nshtmlcomboboxaccessible and nsxultreeitemaccessible, we also need to override the shutdown() method, so that the children get removed from memory when the parent is shutdown. in that case we also override ::getaccnextsibling(), ::getaccprevioussibling() for the dom-less children; otherwise they do not know how to find each other. it is also useful to override these the child getters to return nothing, as we do...
...e: some accessible children are generated by the accessible parent, because they have no dom node. these accessibles cannot be shutdown by traversing the dom, because their cache entry is not based on their dom node. therefore, the parent that generates these accessibles must also be responsible for shutting them down when their shutdown() method is called. this is currently implemented for nshtmlcomboboxaccessible as wells as nsxultreeaccessible. 6. future directions in general, the accessible api module work should now be coming to a conclusion. unfortunately, we still are not fully working with any major screen reader, screen magnifier or voice dictation product on the market. we hope to change that soon, and are working with the major vendors (and gnopernicus on linux/unix) to achieve this. i...

.... in a multi-line use (when aria-multiline is true), return or enter key inserts a line break. javascript features all features associated with any and all properties and states must be maintained, and forms submission on enter or return on a single line textbox needs to be handled. focus event handler and aria-activedescendent attribute if you are implementing a composite widget, such as a combobox composed of a text box and a listbox, you need to manage the aria-activedescendent attribute using a handler. before using this technique, ensure that the browsers you need to target currently support it. see the specification of aria-descendent for further information. it is a better practice to use an <input> element with type="text", or a <textarea> element instead of the aria textbox role.

...tyle bits for a window, so at products only look for it only when necessary. in fact, when a control has its own window, it's easy for a 3rd party application to know whether the object is disabled, focused, hidden, checked, etc. some assistive technologies will look for msaa if it doesn't already know that the given window class is used for something common. common examples are button, listbox, combobox, msctls_statusbar32, msctls_trackbar32, #32770 (dialog class), systreeview32, static, edit and richedit. other assistive technologies use a whitelist, and must list your window classes somewhere in their implementation, and then turn on msaa support when a window of that class receives focus. the window class is also used to determine a host of hard-coded behaviors, such as whether or not a scree...
