Description

Many list and tree controls used in VirtualBox 2.x are inaccessible. Under Windows, an IAccessible object is created, but it has a role of ROLE_SYSTEM_CLIENT and no other useful properties, which suggests that QT doesn't know how to make it accessible. These controls include:

  • The list of machines on the Details tab of the main window
  • Both controls (trees?) on the Snapshots tab of the main window
  • The control (list?) on the Description tab of the main window

Note that these controls were previously accessible in VirtualBox 1.6.x, so this is a regression.

I've just discovered that this is not entirely true.

When you first move focus to one of these controls, a focus event is indeed fired on an object with an IAccessible role of ROLE_SYSTEM_CLIENT. (This was definitely not the case in 1.6.x.) However, this object has the real control object (list, tree, etc.) as its only child. If you move to another item in the control, that item will have a focus event fired for it. Nevertheless, a focus event should still be fired on the focused item when first entering the control.

These subsequent focus events are not detected by NVDA due to several issues resultant to #3588.

My apologies for the confusion.
