/** @brief This interface gives access to actions that can be executed
|
|
for accessible objects.
|
|
|
|
Every accessible object that can be manipulated beyond its methods
|
|
exported over the accessibility API should support this interface to
|
|
expose all actions that it can perform. Each action can be performed
|
|
or queried for a name, description or associated key bindings. Actions
|
|
are needed more for ATs that assist the mobility impaired. By providing
|
|
actions directly, the AT can present them to the user without the user having
|
|
to perform the extra steps to navigate a context menu.
