Accerciser's interface contains a tree view, namely Application Tree View, that covers all accessible applications currently running on the desktop. To create this tree view, Accerciser uses the AT-SPI's registry daemon. This daemon is responsible for keeping track of all the accessible applications on the desktop and forwarding X events over the AT-SPI D-Bus. After getting all accessible applications, Accerciser represents each one of them as a hierarchical structure with expanding nodes.
The first node of each application represented in this tree view is the application itself. When you expand a node, you can see all of its child widgets, which allows a hierarchical view of the application's interface. For each node, Accerciser provides some basic information, such as its name, role and number of children.
Be aware that nodes with many children take a long time to expand.
Accerciser allows bookmarking items in the Application Tree View for later examining. This is helpful when the target application must be restarted - after rebuilding it, for example. To bookmark an item, select it and do Bookmarks ▸ Add Bookmark or press Ctrl+d.
Bookmarks to accessible items in Accerciser are defined by an application name and a "path" in the application's internal accessible hierarchy to the bookmarked accessible. When the target application is in a different state - i.e. multiple top level frames -, the path might not be correct. Bookmarks could be managed by accessing the bookmark editing dialog through Bookmarks ▸ Edit Bookmarks.
